That engineer is a perfect example of what good vehicle maintenance does over the life of your vehicle. Those bearings were still smooth. Minimal piston wear, good rings, etc..etc..etc.. This UA-cam channel is great. I love it.
its been scientifically proven engines last longer when they run and drive at operating temperature and not go through many cold starts and warming up periods. this is why semi-trucks can last over a million miles.
@@ericmartin2470 Semi trucks also run at much lower RPMs, have thicker cylinder walls, larger bearings, stronger connecting rods, produce less power per liter of displacement, are usually made from stronger alloys, hold significantly more oil. Apples to oranges
How cool would it be to see this exact engine completely rebuilt and put back into the same truck and have it monitored for the rest of the trucks life. Might be history in the making!
In the late '90's, using parts I rounded up on Jegs/Summit, I built a pre-start oil pressuring system. I used a small tank, connected through the oil pressure sensor, wired to my ignition. Before I started it, by turning the key on, it brought the oil pressure up to about 5 psi and then I started it.
A neighbor of mine has a 92 Ram250, 5.9 Cummins, 4x4, 6" lifted trucks on 35" tires since it was 3 months old with 1.3 million miles...! He has never missed an oil change and just put it's third manual transmission in it a few months ago, but it's engine is still going flawlessly...!!! Thanks for sharing... Keep up your awesomeness. ..!
@kurtisstutzman7056 see if he’ll let you do a video. We wanna see this! Not because I don’t believe you but because that’s freakin awesome! Drop a comment back here if you put one up so we can go watch! 👊🏼
Just found the channel - great testimony to proper oiling and filtering. Former Worldwide Powertrain Planner for GM here. The likely reason they chose the needle bearings was lower friction, lower weight and thus more available power. That these needle bearings made it this far shows Ford engineers made the RIGHT decision, not the wrong one. It could certainly be argued the bushing has more surface area, but only an engineer could tell us what the bushing tolerances would have done with a lot of heat cycles and the normal amount of dirt from a typical engine. This was certainly an outlier. Bravo to the owner. I hope he checks in here. I'm sure we'd give him a standing ovation if he walked into a meeting with my peers. An engineer's dream owner!!
Well Dave has a big head and self indulgence, he is not an engineer nor has had any experience in systems testing. He just has a theory. And a problem building failing engines. 😂. Total tool and a complete dickhead. I'm only here for watching the entertainment
We did our best back in the day to break your power stroke diesels they held up toa lot of abuse. nothing like that power stroke turbo whistle. You just got a hammer out all the Cal converter in the pipe.
Very interesting. My first new car was a 1999 Mercedes E300 with 796,000 miles, the OM606 Diesel. The engine and transmission has never been out of the car. It has been running on Mobile 1 synthetic 10W-30. It still runs well. Currently we are replacing the fuel pump because the original one developed a crack and started leaking oil. The goal is to crack a million miles.
I grew up in my dad's shop which was a Mercedes indy shop and the best thing you can do on for that engine is swap you filter halfway through the oil change interval. if you read the old Mercedes maintenance manual it even recommends it. The m103/m104/om606 blocks are one of the best engine blocks ever made. I got rid of my w202 after 350k just because of all the other aging car issue that I did not want to deal with it anymore for a daily driver but the guy I sold it to still drives it at 450k miles.
The 1999 E300 has a system that tells you when to change the oil. Since this car runs on the highway, the oil change interval is right around 20,000. Over this time, the engine has consistently used 3 quarts of oil during this time, unless an oil leak develops. It gets driven nearly 240 miles to work, then a few days later home. It has always been idled a couple minutes before driving unless it is very cold then a few minutes longer.
@@user-oi8tg3dq7tthose Mercedes engines are indestructible. I had a friend who's mother wore out the car and, after setting in the weeds for a couple years, he pulled it and put it in a big 20k forklift. That was 20 years ago and it's still running, though it does burn oil now
I don't know. My grandfather had about 3 diesel Benz and they all were garbage. My brother gave him a old Chevy Impala and he told us the Chevy was the best car he ever owned. He said he wasted all that time playing around with Mercedes 😅
As a retired lube oil engineer with Chevron, this video stresses the importance of maintenance and regular oil change intervals. Not sure what brand of oil this gentlemen used but it was clearly a top tier product. Really enjoyed this video and glad I found your channel.
@@earskinpresley5264AMSOIL is the best.I’ve been using it for 25 years 15-40 in my 2001 Duramax LB7 . It still has the original Injectors in it .I use Amsoil Diesel injector cleaner every fillup since the Truck was new.
@@turtlekoff1 I used Mobil 1 Delvac 15w40 ESP Turbo Diesel oil for the first 750k the balance was Lorenzo’s oil from a company called Insane Diesel, same company I got the bypass oil filter from.
I intended to just watch long enough until I found out what the motor was. I stayed for the whole video. Dave’s knowledge and experience is so incredible and he shares it so well. We’re lucky to have him and this channel to watch and learn from.
My 1972 240Z Datsun had 660,535 miles on it, when we finally scrapped it in 2002. Was used as a family car, and multiple long trips. As a GM engineer, I was able to maintain it and keep it running. However at some point, common parts were no longer available for cheap, so there came a crossover, where a newer car was needed. We also had a 1975 Toyota Camry, which we finally gave away to Goodwill in 2005. It lasted another year, then the new owner trashed it because she ran it out of oil. We saw it along the road, abandoned, looked into the hood, and saw the obvious. It made me cry. Our regular family car, 1995 Honda Accord has 275K on it, and still going strong. I ran an estimate, and these cars have saved us over 2+million dollars, over buying a new car every year.
Nobody buys a new car every year. Stop embellishing and exaggerating. If you bought a brand new f150 every 10 years it would only cost you $150k over 30 years. And that’s if you don’t sell the 10 year old one for anything but realistically a 10 year old f150 still going for 20-25k.
Being an engineer, you were more likely to have mechanical sympathy, and address issues like servicing and checking and changing your oil regularly. I have seen engines where the funny red light which sometimes illuminated, turned out to be the oil light, and needed 4.5 litres to top up. That is just asking for misery. I have also seen a car which was so hot to the touch, that I needed rags to approach the bonnet. Inside the engine bay, the exhaust headers were glowing red-orange. Turned out to be zero coolant and oil. She said, I just need to get to an appointment, and drove off.
I think as far as diesel engines go, operating under load is better for them than just daily driving. Pulling trailers around is keeping the engine running clean along with good maintenance. Same in Class 8 trucks, too. This driver understands his equipment.
I have over 400K on my 2007 Ram 2500 (5.9 Cummins). Most of those miles were on the highway, pulling a trailer. It's retired from long haul driving now, and carefully maintained for occasional hauling. I'm likewise retired, so my daily drivers don't get more than 1500 or 2000 miles per year. It will be my last ever truck purchase, and is practically a family member.
@@vandalsgarage Ram Cummins are Great. I got a 07 Ram 3500 with 6.7 Cummins with 979231 Miles on original engine. Engine never opened up and maintained well with a bypass oil filter using good oils and filtermag on oil filter. Bypass oil filter was only used about the last 1/3 of its mileage. Engine works like new with more power then i need no kidding. Best truck i ever owned Praise GOD!!
My dad's friend invented an auxiliary oil filter and my dad allowed him to put one on my 1982 Rabbit diesel. I drove that car for 496,357 miles. The only part of the engine that was ever opened was the oil pan to plumb in a return line, and the valve cover to replace the leaking gasket. Sold the car to a diesel parts shop as a parts runner. The filter added 4 quarts to the system and changed the oil every 10k.
Big truck engine maintenance uses bypass filters. Oil is lab tested at regular intervals and topped up. Oil is very rarely changed because it’s perfectly good.
@aaron-dd5zr if I pulled in behind a semi I could get over 60. Ironically, I had a 2009 Jetta TDI and it got the same mileage as the 30 year old model. I also had an Audi A3 TDI that routinely got 50 and this was a rocket ship compared to the other 2.
Hello Dave's Auto Center. I think the lifters you want for your awesome engine builds are the eeze roll lifters by isky cams which use a bushing with oil lubrication groove design. They were commonly used by big daddy don garlitz on top fuel engines, I saw them on the engine build parts lists at don garlitz museum. Hope it helps
@philipmilsom9544 Dave's machine shop only needs to manufacture their own similar lifter that's more affordable. I believe a set of lifters from isky is far cheaper than buying 1 at a time, call for pricing. If daves machine shop pressed out the lifter pin on a stock lifter, they could easily machine a bushing to fit the oem roller wheel and lifter pin. There's endless possibilities when it comes to creativity with a pro engine machine shop. I mentioned the lifters because they have the correct design dave mentions would be better than roller bearings, the rest is up to the creative people at dave's. One other possibility to extend roller life is to use a larger roller on the lifter to reduce roller rpm. I've seen some engine builders use a cam cut from a larger diameter core to achieve the same lift and duration with less transition onto the lobe to reduce wear on roller lifters. Theres lots of ways to deal with roller lifter wear.
Interesting video. I got a 07 Ram 3500 with 6.7 Cummins with 979231 miles on original engine.

Congrats on that impressive mileage. I’ll bet Cummins would be interesting in researching y items engine. What sort of emissions problems, if any, have you had? What sort of fuel treatment, if any? What kind of oil?
Thankyou for the congrats, yea maybe Cummins would like to buy my truck even? It would take a lot of coin before that would happen. Emissions problems i had around 2014 with the 3 converters in the exhaust plugged up at around 430,000 miles. Put in a straight pipe and had the computer system emissions deleted and tuned for better fuel mileage and that was a great improvement in fuel economy, performance, reliability and cooler running engine. Fuel treatments i don't always use but have used lucas fuel system lube, power service in white bottle, ATF, others i can't remember the name. I also modified the fuel system to half inch line all the way into the tank with high temp hose and built a heated fuel system from engine coolant heating a remote mounted fuel filter using a CAT 1R-0750 spin on fuel filter. I relocated the Dr side battery into the bed and then Put a aluminum pad where the battery was under the hood and built the heated fuel filter system on that and it worked better then i expected and tested flawlessly at -40 in cold winter night long distance trucking pulling new Campers. I also have run waste oil in the truck at times with the heated fuel system but its not convenient now to play around with pre filtering waste oil were i live but my truck can run it no problem. Now i just stand beside my truck and spin off the fuel filter and spin on the new one the way it SHOULD have been from factory. The oem fuel filter is nuts to get at having to remove the battery and stand on a toolbox and wiggle both arms in by the engine with a special plier + chemical resistance gloves to access... Not a fun job especially in the cold of winter when the fuel filter plugs up.. I been in some scary cold situations and had enough that the next summer i built my heated fuel system to save my life and it was sure worth it.. Wish the manufacturers had the option to have a heated fuel system and a fuel pressure gauge in the truck while they are at it... They don't care that much... To this day a diesel truck is $100,000 give or take and you don't even get a fuel pressure gauge.. Diesels need a fuel pressure gauge just like an engine needs a oil pressure gauge. When pressure drops you know its either the filter is plugged or the fuel pump is going out or there is gel in the line... Engine oil was rotella T 15w40 a lot of the trucks life but i got the truck at 390,000 miles and kept using that brand of oil and lucas oil stabilizer and powerup metal treatment.. I later switched to mobil 1 0w40 synthetic ( using the same additives ) after finding tests that it was 1 of the best on the load bearing test bench. Later Amsoil Signature series 10w30 tested better so i switched to that... Also added the frantzfilter bypass oil filter that uses a toilet paper roll to clean the oil better. I could go 4 times as long on my oil changes after that and it saved me time and money and helps the engine... Back in Jan 2022 i lost my trucking job because some big shots thought i needed to inject some dna altering venom in my veins to continue trucking. I said no way as i want to live and so here i am now still heathy with a healthy truck but no job and lots of debt... Last oil change i did on the truck was jan 2022 using a jug of Lucas oil stabilizer and a jug of Amsoil signature series 10w30 and a jug of motorkote as an experiment and its thick but no problems and the oil is fairly clear still with only a slight tan color from new color... Truck has hardly any rust for living in a rust belt area in Canada. I oil up areas on the truck with wd40 GEL Lube and highly recommend all vehicles be soaked with that oil or Krown works to and my Brothers garage uses krown and its great to and creaps into areas better... If you don't drench your vehicle with oil then rust will have the pleasure of destroying it for you at your own expense!!!! Best thing is to drench a vehicle with oil from new on then once a year after that. Oil in the rockers and frame inside and out, in cracks and crevices and inside doors but remove the panels and clean out any grime at the door bottoms 1st because it collects there over time. Soak it when it new is the best ans it key. Overall i was Blessed with a Great truck. Proper Maintenance Extends life and that goes for more then just vehicles 🙏
@@Emory561 This was such a great reply. Believe it or not, I’d still watch a video on your truck if you explaining all that. I’d bet you’d get 20-50k views just naming it something like “Ultra high mileage Cummins. How long can it last?” Then put a camera close up shot of the odometer and a photo of the truck. Walk everyone through what you just said and show the filters and the tank you built. People like seeing things that are out of the ordinary. A truck with nearly a million miles is pretty far from ordinary. If you’re worried about emissions stuff getting you in trouble skip that part. I would like to recommend you looking into fuel bypass filters. Without knowing what kind of fuel pump you’ve got, it’s an amazing way of preventing an engine or injector failure. I am pretty interested in the S&S Diesel bypass fuel filter. They destroyed a filter and it survived preventing the shrapnel from getting to the injectors. That’ll save an engine death or 10k repair bill and it’s like 450 bucks and a few hours of time. Okay now the response: Thanks for taking the time to respond. It’s fascinating you are able to burn anything in the engine and the injectors without worrying about clogging. Sorry about Canada going crazy and forcing vaccines. We had it too here in the states and it’s unacceptable. Glad Biden and Trudeau are out so we can get some new life in our spirits. It’s also interesting you don’t trust Amsoil by itself without the stabilizer. Oil manufacturers talk about stabilizers being an impediment to their chemistry. Amsoil seems like it’s best without any additives according to their promo videos. I’m no expert so I wouldn’t want to tell you to change anything. It’s just a point of conversation. I’m curious what fuel pump you have and if you’ve changed it. Don’t ever let the tank run dry. That’s apparently what kills CP4 pumps and destroys fords. As long as it has fuel apparently it’s a great pump. Who knows? CP3 doesn’t seem to fail catastrophically in the forums online. Either way a bypass fuel filter would completely eliminate this worry. I haven’t heard of Frantz Filters but I’ve heard people say the toilet paper thing before. It’s pretty fascinating they use a roll of toilet paper. Seems like it works great. I would love to know how well it works when comparing to the Amsoil or Insane Diesel bypass filters. A roll of TP sounds much cheaper than a filter from them. As for fuel additives. Seems like you didn’t need those as much. I wish we could get good data on whether they’re worth it or not.
I have ran the FS2500 oil filter for 650,000 miles on a Cummins 5.9 24 valve. I have no issues with the motor except a few oil leaks. I still drive the truck daily.
Don't forget that $pec oil every 5k, all the additives, driving it "daily", the DPF clean out(s) and two shakes of a voodoos stick every morning. Miss one and it's YOUR FAULT the pump blew up, etc., etc. Diesel dudes be funny.
Wrong... evidence proves if an engine runs and drives at operating temperature with less cold starts and warming up periods the engine will last much longer. this is why semi-trucks can last over a million miles. you herd the owner say "I haul campers".
@@ericmartin2470people that use trucks personally always have now failures than commercially used trucks in my experience. Unless it's a Dodge/Ram they struggle to last no matter what here in NY.
This engine use case is interesting because the guy obviously did regular maintenance, plus he benefitted from very long duty cycles driving campers across the country (the opposite of stop and go). In addition, he also had that 1 micron filter they mentioned at the beginning of the video. HOWEVER, he did also say in an earlier video that he did idle the truck all the time. Remember he said he would regularly sleep in the truck on long trips and idle the truck overnight, contrary to what Dave said at the 16:15 mark. To me this says that excessive idling in a vacumm is indeed bad BUT if you are doing regular maintenance and running the truck for long periods at peak (non-idle) engine temps, you can still prevent a lot of engine wear and carbon build up. Thoughts?
its been scientifically proven engines last longer when the oil is at operating temperatures and not having to go through a warming up period with frequent cold starts like you see in a passenger car. if auto manufactures implemented oil heating to 160 degrees followed by pre-oiling before engine start then we would see engines lasting much longer. but who would go through a 20+ min sequence before starting?
@@ericmartin2470 Heating the oil also heats components, which reduces wear on start up’s . The cold and hot cycles are extremely hard on engines. A cold engine on start up has less clearance between components. Pre-oiling would be beneficial. Could we get people to plug their gas or diesel engines in to maintain temp?
Dave I watch a lot of your videos. One thing I see. Removing a steel oil pan with a chisel etc almost always damages or destroys the pan. If you use some gas heat on the flange it softens the sealer and the pan falls off. No damage. Keep up the good work.
I'm a electronics technician now. Retired from the USAF over 20 years ago, after 20 years of service, as an Air Craft Weapons Mechanic. Loaded bombs, missiles, guns, and kept the acft weapons system up and running, electrical and mechanical. Then after retirement, put my skills to work for several copier companies. Xerox and a couple of other local companies. In one of the companies I did a lot of Canon copiers. We had one copier, a canon 6000 series. Never had a problem. Just the one. IT had parts that wore out, but they were designed to be replaced. This one copier weighed almost 2x as much as other 6000 series. Thats nearly 800 pounds. The copier is about the size of an average home washing machine. We joked about that one machine as being the prototype that got sold. And as you know, prototypes are usually built way better. then later, substandard parts are then put on the assembly line. To see all that... my first thought was no way nearing a million miles. WOW. Thats got to be one engine where they used the same parts the prototype had on it. With parts like that on it, keep them on the engine. until they need to be changed. You might not ever change them.
You can use a ball bearing with a flat micrometer to measure a bearing's thickness, just accurately measure the ball bearing first, then subtract that from your measurement.
@TucsonDude a ball bearing is perfectly round, what are you talking about? Plus you measure the ball bearing then take that measurement into account when taking your final measurements.
FYI: The oil was drained, it’s in the gray bucket on the ground behind Dave. Any oil that’s coming out now is what has settled in the oil pan since it was pulled out in October. Also , this engine is packaged as a core that has to be sent back to ford as what they consider a long block. In the summer of 2023 the ford dealer in Wyoming had to reseal the upper, lower oil pans, and the front and rear cover. Spring of 2024 the upper oil pan was leaking again, come to find out when the repair was done the first time the tech inadvertently stripped the bolt hole in the rear cover which caused the new leak. So the job had to be repeated with the addition of a new rear cover.
A long time ago now, I drove commercial charter motor coach out of Ohio. Our owner had about 120 coaches. Some were 6V92 and some were Detroit 60 series. (Yes, I am old). We all knew that those engines could easily go 1.5 million or more. But they were swapped at 500k. PM and passenger safety was first on the list.
@@dsstaang new semi-trucks needs to meet EPA regulations put in place during Obama. this has had a detrimental effect on diesel engine longevity. the reason you'd see 2.5 million miles is because those truck engines spent the vast amount of time running at operating temperatures and not having to go through cold starts and warming up periods. the motor oil needs to be above 160 degrees to lubricate properly.
I put the Amsoil Bypass filter on my old Ram. It filters the oil down to 2 Microns. And I only run Amsoil full synthetic oil. Also use their diesel fuel additive
Better efficiency but yeah less reliability from needle bearings. And i.m.o. bronze bushing thats can impregnate with oil will always be better long term than a roller
Generally when calculating life time of bearings there is a 10% failure rate used. Reason is that there are so many parts with individual tolerances. So you check the lifetime but accept failure. Benefits are less friction - after 900k mls this is no failure, it is just wear due to concept.
As an automotive technician for over 30 years, I have always made it the first priority for myself and my customers to always change the engine oil at the recommend intervals or before. Proper maintenance will greatly extend the life of your engine. Remember if you don’t do proper maintenance it will cost you a new motor or more and if you change your oil too often it will only cost you the price of the oil and filter.
That makes complete sense….if there was no other way! With the filter I use and oil analysis you can save your customers time and money for a minimal initial investment. This filter from Insane Diesel really is a no brainer for anyone that plans to keep their vehicle and maximize the investment.
As my late Dad always said "oil is cheap, engine parts are expensive". I change every 3k synthetic and often on my 2001 f150 supercrew it's 1000 because a yr has passed 😉 but yes oil and filters ..
I realize it’s apples to oranges, but I have 1,980,000 on a 2006 International 9400i with a Caterpillar C13 engine. It had an in frame overhaul at 1100,000 miles due to a head gasket failure. Since then, with the exception of one injector electrically failing, the engine has been flawless. I use the FS2500 spin-on filters, Cat oil and fuel filters, and Rotella T6 oil, and the only fresh oil she gets is when the filters are changed every 20k. I finally had to change the oil last month at around 475,000 miles as the lab said it was time. Since the engine overhaul, i think that’s only the second oil change. When the injector was installed last year, the tech at Lansing Cat commented how clean the engine was inside. Bypass oil filtration is a huge game changer!
So cool to learn all this in my 50’s. In high school, I always had my head under the hood. Life took me down a different route but now I am spending a lot of time doing what I always loved. Just got done swapping out my 2002 7.3 L. I put an old motor from a well-maintained bus with 200,000 miles on it. The church I bought it from did regular oil changes. No EGR runs awesome.
Clint , of Custom Works, a 7.3 YT channel, already showed the data specs which filters are best on our diesels. The AMSOIL “by pass” filter on their dual filter set up, is Unsurpassed, other filters can use , Donaldson BD7405, Baldwin B7039, Total purple filter, Amsoil EA099, Mobil1. on & on. You’re Welcome.
All Fram filters are trash! Will never use a Fram. Had 1 that had a pinhole in the side, and engine lost oil pressure, it was a chevy 6.0 , thankfully the low oil pressure light came on n I stopped in time
Dave, you guys should’ve gone over the bypass oil filter setup in-depth and told viewers what the brand was and such. Maybe that’d be a great idea for another video on this truck/engine. It’s obviously a great product, and everyone in the comments is curious about them after watching this. I know you don’t make em, but it’d still be cool to shoutout a good product and tell us all about it. I guarantee you’re gonna have people interested in them after seeing inside that engine, so I hope you either start sellin em or tell people where to get em.
@ because this is America and I can watch and have an opinion about anything that I choose. I also have the freedom to type and share my opinions on public platforms.
@@paulbennett274Awesome, I see it now. I couldn’t find it when the video came out so idk if it was there before or I’m just blind lol. I hope Dave does an in-depth video on the system in a video cause it’s obviously something that works and I’d like to hear more about it and how it looks mounted in the truck and everything.
Reason this diesel made it to almost 900k miles was because the engine worked non stop for the majority of it's life. Cold engine running, stop and go, and idling is what kills engines both gasoline and diesel even more so than extended oil intervals.
The secret behind all these high mileage cars, vans, trucks. Frequent oil change, forget what the manufacturer's say, change the oil and filter every 3'000 miles. The other thing that helps is not too many cold starts, this guy ran his truck for 12 hours a day, so most of the mileage was done on a warm engine and warm oil. Any engineer will tell you, most of the wear on an engine is done in the minutes after start up of a cold engine. Treat her gently until you have her up to running temperature.
Nah the owner is in the comments he changed his oil every 15k miles and had them test it every time. They actually told him it was still viable but he changed it anyway.
The hate spewing over a 900k mile engine that literally needed a cam and lifters to be good again is absolutely ridiculous. Say what you want about the "flawed" oiling system, it apparently works just damn fine.
I think it’s more of pointing out ways it could be improved. And he mentioned he’s seen many fail at lower mileages. Some people don’t hate, has nothing to do with emotion, other than passion to improve things, maybe every engine would last 900k with that kind of… “hate.” 🤘
Back in the day when I used to build two-stroke dirt bike motors, the lower rod bearing, and it was a needle bearing, it would always fail, & the needles would get sucked through the ports, and it would always end up chewing up the top of the piston. It would always happen on the real high horsepower KX80, CR 250, last one I did was an RM250. They would press the crank halves together, in the rod was a solid piece with needle bearing between the crank journal. I can't tell you how many cases I split to change the rod bearing in a 2-stroke dirt bike....
I love your channel Dave. Although I now work as an engineer, in the field of biomechanics, machines have always been my love. Sometimes that's why I stop by my old workshop and visit the old team and the new owner who was my young worker 20 years ago. We look together at what is on the table and what goes into processing, and we almost always end the discussion on the fact that today there are not so many bad engines, as there are many bad owners. Dave, I congratulate you on a job well done as always (although I know there are days in our lives when it would be best if we stayed in bed that morning) and I wish your team and you much luck and success. P.S. there is no going back now, stay good as you are.
Really enjoyed the tear down and reading the comments on this engine. I think if I were this guy and could afford it, would buy a complete engine, so everything is new. I’m sure Dave will build a great long block but everything else has almost a million miles on it.
What I brought to Dave’s is what Ford Motor Company calls a long block. I would never bring something to someone the way “I” wanted to bring it, that would be rude and disrespectful. I bought a long block from Ford, it was shipped to the dealer on this exact pallet, and that’s how they wanted the old engine returned. During editing some things get left out! 🤷♂️
I brought my engine to a shop to get rebuilt. They where annoyed it still had the oil pan on and intake. I don't get it. Just charge me more to take it off and give me an option to charge me more to put it on. Why get all pissy. You are in it to make money. You have the tools and knowledge to do it, why not just happily take my money and not be a little b*tch about it. Also I dont have a parts cleaner to clean my oil pan and intake, so I need your equipment to do that. That being said I like the videos and thanks for the videos
In Dave's case, he's generally dealing with other businesses, which are fully capable of stripping the block. Like he said, this engine was shipped by a mechanic. They should should know better. I knew the differences between short and long blocks, and complete engines before I was 10 years old. Shipping it full of oil was the icing on the oil cake. I understand your position, but businesses rightly determine what their needs are. They could have been more gracious about it for sure, but at base, you and that business were a bad match, and you should have used a more suitable one. As a locksmith, I've been asked to do things that were illegal, unethical, or just outside what was sensible and profitable for me to do. You think you should tell someone to "just" do what YOU want them to do. Sorry, but no. Get real. Call someone else. Period
Ya i didn't see what the fuss was about. You call yourself an engine rebuild shop so take the oil pan and the valve covers off and charge accordingly. Wtf's the big deal ?
Was that truck deleted, I’m sure it idled a ton being that was his home but taking epa out of the equation resulted in that truck going that long with his stellar maintenance to help!
I didn't hear Dave ask the guy about idle time, but he said he spent 12 hours a day in his truck, so I'd like to hear from him about his idle time. Everyone wants to know about the brand of oil, but I'm more interested in the filter. Subaru developed an oil filter that I used to use called a Trasko. It's a canister filter and you replace the element. The element resembles a roll of toilet paper, but it wasn't. It also had a super fine stainless screen that would capture metal flakes. The first oil change on my Fed Ex Ground Workhorse P30 had about five flakes of metal in it; I about filled my shorts. I added Lucas at my monthly oil changes and never saw another flake. I sold the the truck at over 300k miles and never had an issue with the motor.
As a gear head since I was a kid I was always told that if you do proper services on diesels you should get a million miles out of them and there’s your proof. What a great video !! First time seeing a diesel motor hit those miles with a tear down and showing that if you do the oil changes and do the proper precautions of taking care of a diesel motor that’s the out come. Love your videos Dave. You have a great crew as well. Take notes people !!!
I'm impressed . Almost 900,000 MI and those main bearings look perfect well I guess what really says that you really need to put a better oil system in and what the guy put in better stuff to keep your oil clean and your temperature is down and if it had better lifters that would be a million mile engine wow thank you Dave for putting such good videos out about diesels I had a 6.2 Ford on 85 f250 and I thought I maintained the engine really good I got 400,000 miles before I got rid of it I always put a bigger oil filter on and I had a dual rancor fuel filter system and I always added additives to my fuel and that engine always ran great it finally started to I had a head gasket go out and about $410,000 MI so I had to get rid of it but it was my favorite truck
As I recall, this guy was doing 10k-15k mile oil changes with a bypass and oil analysis. Is Dave’s motors going to require him to change oil at 3k as it states on their website for warranty? Dave is marveling at how clean the engine is, and at the same time telling people to cut their service interval in half. This thing was going almost double the recommended oil change interval and it’s spotless. But the guy was doing it the right way. My hang up is Dave require proof of 3,000 mile oil changes for warranty. This is proof that this policy is out dated and not friendly to the customer.
@ you aren’t wrong but that has nothing to do with the oil. It saved his CP4 pump for sure. But the bearings and pistons look awesome for an engine 1/4 the miles. His oil change interval was perfectly appropriate at more than 10,000 mile intervals. Is Dave going to honor his engine warranty at this interval or is he going to stick to the 3,000 miles as stated on their warranty page? That’s the question
@@mebordernoneya8484 The owner was always doing very long trips delivering stuff (he did say but I can't remember what he delivers). That in itself means that the engine was always running at highway speeds and under load. Any carbon build up under those conditions would be extremely small. Even if he did sleep with the engine idling (as he said he did) when he is back on the road again any carbon deposited from idling would be burned off in no time.
@ Dave’s engines sells long blocks. Emissions has nothing to do with a long block other than being built with the right compression ratio, quench, and valve recession. Emissions all happen on equipment bolted to the long block.
Keep some of the rod bearings in an exhibition for customers and tell them the mileage with regular oil changings. Put failed/scratched/worn out bearings of a low-mileage engine with bad maintenance besides them as a SHOCKER.
Some awesome quality work here, it’s great seeing people taking the time to properly diagnose a issue and work out a solution to resolve or avoid the problem, I’m from Australia I run a small mechanical shop but that’s probably one place I could work for! Finally some real experience
My old '01 F250 7.3 I bought new and sold to my friend in '05 is still on the original engine at 760k miles. He runs it hard, but he's meticulous with maintenance and runs Amsoil diesel fuel additive in every tank. Modern diesel fuel is garbage. Probably the best thing you can do for a diesel engine is add some lubricity to the fuel and keep the filters changed.
I twisted my Dad's arm to start adding a bit of power service every other fill-up on his 1997 7.3 and he hasn't stopped bragging about better mileage and running super smooth. You're right ..we have crap diesel anymore, these poor engines need extra lubricity.
You can thank Al Gore for “dry” diesel fuel. He had the petroleum industry take out the surplus that lubricants the fuel. The supposedly low emissions regulations. Total and BS technology.
Dave, nettle bearings spread the load more than a bushing will, think about it you can't have a dedicated oil supply so the impact would be on just two areas of th4 lifter. The needles move around so the load isn't iin the same area every stroke. The total area covered would be less than the needles. I think they designed the lifters the best way, not the only way, but the best for a push rod engine. The best way would be with overhead cams. Push rods are for lawn mowers.
This isn’t totally true. Bushings apply the load to the film of oil. Needle bearing apply the load to the needles. There is a reason pistons and main bearings are bushings and not needle. If flowing oil is available bushings are better. If flowing oil isn’t available (such as a drive shaft yoke) needle bearings are better.
Its not just maintenance. This man worked his truck. Diesels need to be run . Driving around town short 15 mile trips are what shorten the life of a diesel. Towing is great it burns cleanest.
Always great advice from the expert who knows engines. This is a great example of how proper care and maintenance affect a diesel engine. Thanks for making this video. It is an inspiration for those who care about their engine. Don’t idle unnecessarily and change the oil and filters with good quality products at frequent intervals! Simple!
To be fair, even roller lifters are meant to be replaced before 1m mile. The fact this engine lived this long is a testimony to the fact we can still build relable shit they just need to get rid of the cp4 pump and emissions junk almost every failure point on this engine was designed by bosch can't be a coincidence
I'm having a head rebuilt on my dad's 318 a Dodge Ram with 465,000 mi. Got a leak in the head gasket the day before Christmas. Only thing I've done to is replace the headlight switch the ignition switch an added the additive tribotex to the motor rear end and transmission at 420,000 miles.
The hardness, surface finish, and roundness of the inner sleeve, the outer sleeve, and each needle must be maintained to have a successful needle bearing. The shortcoming of these systems is the finite point contact between the needles and parallel surfaces compared to a bronze sleeve with oil film. The size of the needles increases or decreases rolling resistance based on lubricant, cleanliness, and metallurgy. There's a reason needle bearings aren't used on crankshaft mains or crankpins. All that's necessary is to polish those surfaces fine enough to prevent any asperities from poking through the thin oil film in operation. Maintain the oil pressure and film strength, you have zero metal to metal contact. The oil fluid becomes the bearing.
I have marine engines. I centrifuge my oil every 50-100 hours. The centrifuge returns oil to semi transparent, almost as clear as new. Because the engines are free of sludge, the oil never gets completely black. I test the oil once or twice a year. Before I started using a centrifuge I used a bypass filter. I get 2 or 3 times the service life between overhauls than others using the same engines in the same service. The biggest difference is in the sleeve and ring wear. But my bearings also look like new. Crankshafts don't wear. I haven't ground a crank since the 1960s. Clean oil makes a huge difference. I also drain my PU and run the oil thru the centrifuge. I like having people check my oil for their expression when the dipstick has transparent oil. I'm anxious to use speed of air pistons.
@@MIKEmofit There's always going to be wear, but the cross hatching lasts 2-3 time longer and is usually the deciding factor for overhaul. Mostly 2 cycle, so I can see the piston and sleeve thru the ports.
@@davidrosenbloom6652 All the diesels are plumbed in to a gear pump that sends the oil to a heated tank. Each engine pan has 2 valves for safety. After the oil is in the tank, it's pressurized and that pushes the oil to the metering valve on the centrifuge. The centrifuge separates out oil and water. The finished oil drains to another tank and pumped back to the engine. Usually the oil is centrifuged after a run while it's hot. It separates better. The dirt is lightly embedded in the bowl and isn't cleaned every time since the engines are clean. Final oil cleanliness is controlled by how fast the oil passes thru. I drain my PU into a bucket and take it to the ship. There's a deck fill that goes into the tank. After the centrifuge the clean oil is diverted into a clean bucket. I use Shell Rotella T4 in everything. Marine engines were overhauled 12 years ago and had a bypass filter, so cleaner than the average engine when I started. Mains are Detroit Diesels. If I was younger, I'd put one in my PU. Others use the same centrifuge for biodiesel, etc.
@@oceanmariner Has the oil ever been sent for analysis after the centrifuge process? I can see the water and debris are sufficiently removed from the oil but I'm wondering if the usual breakdown of oil hydrocarbon chains (and associated lubrication strength) are still occurring at rather normal rates for the use of the oil, in spite of removing contaminates.
coming from a ford tech, that is how ford sends most (LONG BLOCKS), pan, front cover, rear adapter, etc. some of those parts on certain engines are integral to the assembly, oil pick-ups and such. what you sell is closer to a short block with heads. I would put money on it that is deleted as well.
Exactly what I was thinking plus those parts protect the inners from damage and moisture... Dave's being so picky on certain things it could bring more issues.
Actually, it probably doesn't have anything deleted as this guy has to have a DOT inspection every year in order to haul campers. Running all highway miles with a good diesel additive keeps the DPF in the best shape that a DPF can be in.
@salsuginusrex5196 you obviously don't know how things work, for example in CT where I live if your registered 10001 lbs you're exempt from emissions, if you think these guys are not exploiting every lope hole you are a fool
If you add his total engine idle hours of 4,714 and times it by 30 = 141,420 miles and you add his odometer mileage of 892,315 = 1,033,735 total miles on his engine.
Ford: produces a 900,000 mile engine. Also Ford: the 2.0 EcoBoost in my '18 MKC failed at 37,000 miles and the replacement engine failed after 5,000 miles. Religiously maintained. Suffered the notorious coolant intrusion issue twice
Probably Synthetic Rotella 15w40. Probably changed every 5000 miles. But considering the advanced filtering system, and road traveling without stop and go, might he have gone to 10k but I doubt it. Very impressive life out of a motor especially considering how hard he worked it. I would probably guess 5000 mile changes.
@@phil4986In the first video with the owner and Dave’s son Miles the truck owner said he did oil analysis routinely and based on how well the oil did he started with 5000 mile changes, then 7500 and I believe he ended up going at least 10,000. But it seems the key is that the truck ran 12 hrs a day every day towing travel trailers from coast to coast. The engine was always at full operating temperature with clean oil and fuel. I have an acquaintance who also towed travel trailers with his Ram 3 liter Ecodiesel and got 462,000 miles on the first engine and over 300,000 on the second before he moved up to a Cummins. Modern diesels need to be run, little idling and longer trips. City driving and modern emissions don’t go together. Look at Dave’s video before this one “Looking at CP4 at 900,000 miles.”
Amzoil with a bypass filter. 325k on my Mazda pickup. Changed oil 5 times. Engine was clean as a whistle and ran like a top! Got tired of driving it. Sold it after 14 yrs and 325K.
I wonder how many times those injectors fired. Those bearings proved how important oil changes & filtration are. I would have NEVER thought bearings with that many miles on them could look that good. Think how many times that crankshaft rotated with all that pressure on it. Amazing.
Ain't no body gonna talk about the Toilet paper oil filter his friend built that the owner used from the first month he bought his truck? To get it almost 900K miles.
I use a filter by Gulf Coast that uses a roll of heavy duty paper towels. Works great. I drain and replace six quarts of oil from the filter and change the filter every 5-10 k miles. Oil analysis always says the crankcase oil is good to run. I usually change all 20 quarts of oil the bypass and full flow filters every 30 k or so. 25 years and going strong. 2000 7.3
This man is the only man in the industry trying to improve quality (Less Profit). Every manufacture is trying to produce the worst product that they can sucker you into buying (to maximize profit at your expense). Companies have been disimproving things for at least the last 50 years.
@@Vikturus22 fun thing is that depending on your location and dimension for distance measuring the „barrier“ is different - million mls or million km. 🤣 With around 1.5 mio km and these clean journal bearings - really impressive.
I usually only idled when it was very cold or very warm, total engine hours(running and idling) 24,610 which is 19.2% idle time. Higher than I would like but necessary!
Must agree with Dave again. Solid bushings is the way to build it. Heavy duty truck-equipment engines have always used solid bushings for any high load bearing application. Surprised there isn't an aftermarket replacement for the cam followers. Newer HD diesels 12-16L are all overhead cam anyway which is a far better design than cam in block with pushrods. Heck, the auto industry figured that out decades ago.
@@MIKEmofitprogressive 10 micron down to 1 micron bypass oil filter, religious oil analysis, high quality oil, and don’t abuse your equipment! That’s how it looks how it looks! Also, I’ll be providing the service history to Dave’s and Insane Diesel for any “doubters”!
or even delay in ignition/fuel injection, you crank engine 20x and after that, startup. with decompression system cranking would be 2x faster than normal and startup would be easier.
it would be better if the engine had a pre-heater and heat the oil to operating temperature before starting. a pre-oiler would do nothing because engine oil needs to be hot before it starts working properly. Dave got this wrong as does most people.
Dave, excellent video! This is proving the oem lies to us on service intervals. Im glad youre taking the time to bring to light all the manufactures misinformation. THANK YOU.
The magic that made this engine last is the daily long term use without starting engine multiple times a day. He’s using this engine like a Peterbuilt driver uses one.
Correct. An engines internal wear is almost zero once warmed up. So all the number of warm up cycles matters. One one car I drove it 72k miles in one year. It's wear that year was nil compared to someone driving 72k miles in 12 years with zillions of short trips
The needle bearings experience a point load. Theoretically the surface area of the bearing on the race is zero square inches. That changes of course on the quality of manufacture, the wear on the bearing, and the tolerances. It is like a locomotive wheel. It is solid steel in a "perfect" circle, resting an a steel rail that is perfectly flat. What is the contact area....Zero square inches in theory.
"Theoretically" the contact between pin and bushing is also zero. The difference with a larger diameter pin in pin/bushing vs needle is more area is closer with the pin, more area for oil to suspend the pin. Catch-22 is the pin/bushing must have oil else contact is made. Needle bearing can roll with less wear during low oil conditions.
Ball bearings are even worse, especially if sizes aren't perfect, because then a lot of heat will concentrate on the largest bearings and then guess what? My experience is based on the front left on a Mazda MX5 race car where I ended up replacing them as a maintenance item every 6 months, thus getting rid of the failures.
In the first video the owner said he tested his oil the first 2 or 3 changes, then put his changes out at 15,000 miles, and even testing that oil showed it was good enough to leave it in. But he changed every 15,000 anyway. That auxiliary filter must have worked great !
That engineer is a perfect example of what good vehicle maintenance does over the life of your vehicle. Those bearings were still smooth. Minimal piston wear, good rings, etc..etc..etc.. This UA-cam channel is great. I love it.
That is one well designed engine. Those bearing surfaces are amazing.
its been scientifically proven engines last longer when they run and drive at operating temperature and not go through many cold starts and warming up periods. this is why semi-trucks can last over a million miles.
Yeah. The thermal cycling kills them. Also, the engine spends less time at operating temp.@ericmartin2470
@@ericmartin2470 Semi trucks also run at much lower RPMs, have thicker cylinder walls, larger bearings, stronger connecting rods, produce less power per liter of displacement, are usually made from stronger alloys, hold significantly more oil. Apples to oranges
When is the crazy price for a Subaru engine?
How cool would it be to see this exact engine completely rebuilt and put back into the same truck and have it monitored for the rest of the trucks life. Might be history in the making!
I agree! What do you say @DavesAutoCenterCenterville
In the late '90's, using parts I rounded up on Jegs/Summit, I built a pre-start oil pressuring system. I used a small tank, connected through the oil pressure sensor, wired to my ignition. Before I started it, by turning the key on, it brought the oil pressure up to about 5 psi and then I started it.
I remember kits like this for sale in the 1990’s.
You wasted your time congrats
@@nanerpussz why wasted time?
I've thought about building a pre-lubrication system.
Did you find it helped?
They should have an auxillary oiling system with all these start/stop engines.
A neighbor of mine has a 92 Ram250, 5.9 Cummins, 4x4, 6" lifted trucks on 35" tires since it was 3 months old with 1.3 million miles...!

Just found the channel - great testimony to proper oiling and filtering. Former Worldwide Powertrain Planner for GM here. The likely reason they chose the needle bearings was lower friction, lower weight and thus more available power. That these needle bearings made it this far shows Ford engineers made the RIGHT decision, not the wrong one. It could certainly be argued the bushing has more surface area, but only an engineer could tell us what the bushing tolerances would have done with a lot of heat cycles and the normal amount of dirt from a typical engine. This was certainly an outlier. Bravo to the owner. I hope he checks in here. I'm sure we'd give him a standing ovation if he walked into a meeting with my peers. An engineer's dream owner!!
Thank you sir!
Exactly. I’m no expert but pros and cons to all decisions.
Well Dave has a big head and self indulgence, he is not an engineer nor has had any experience in systems testing. He just has a theory. And a problem building failing engines. 😂. Total tool and a complete dickhead.
I'm only here for watching the entertainment
We did our best back in the day to break your power stroke diesels they held up toa lot of abuse. nothing like that power stroke turbo whistle. You just got a hammer out all the Cal converter in the pipe.
Very interesting. My first new car was a 1999 Mercedes E300 with 796,000 miles, the OM606 Diesel. The engine and transmission has never been out of the car. It has been running on Mobile 1 synthetic 10W-30. It still runs well. Currently we are replacing the fuel pump because the original one developed a crack and started leaking oil. The goal is to crack a million miles.
I grew up in my dad's shop which was a Mercedes indy shop and the best thing you can do on for that engine is swap you filter halfway through the oil change interval. if you read the old Mercedes maintenance manual it even recommends it. The m103/m104/om606 blocks are one of the best engine blocks ever made. I got rid of my w202 after 350k just because of all the other aging car issue that I did not want to deal with it anymore for a daily driver but the guy I sold it to still drives it at 450k miles.
The 1999 E300 has a system that tells you when to change the oil. Since this car runs on the highway, the oil change interval is right around 20,000. Over this time, the engine has consistently used 3 quarts of oil during this time, unless an oil leak develops. It gets driven nearly 240 miles to work, then a few days later home. It has always been idled a couple minutes before driving unless it is very cold then a few minutes longer.
@@user-oi8tg3dq7tthose Mercedes engines are indestructible. I had a friend who's mother wore out the car and, after setting in the weeds for a couple years, he pulled it and put it in a big 20k forklift. That was 20 years ago and it's still running, though it does burn oil now
I don't know. My grandfather had about 3 diesel Benz and they all were garbage. My brother gave him a old Chevy Impala and he told us the Chevy was the best car he ever owned. He said he wasted all that time playing around with Mercedes 😅

As a retired lube oil engineer with Chevron, this video stresses the importance of maintenance and regular oil change intervals. Not sure what brand of oil this gentlemen used but it was clearly a top tier product. Really enjoyed this video and glad I found your channel.

@@turtlekoff1 I used Mobil 1 Delvac 15w40 ESP Turbo Diesel oil for the first 750k the balance was Lorenzo’s oil from a company called Insane Diesel, same company I got the bypass oil filter from.
I intended to just watch long enough until I found out what the motor was. I stayed for the whole video. Dave’s knowledge and experience is so incredible and he shares it so well. We’re lucky to have him and this channel to watch and learn from.
My 1972 240Z Datsun had 660,535 miles on it, when we finally scrapped it in 2002. Was used as a family car, and multiple long trips. As a GM engineer, I was able to maintain it and keep it running. However at some point, common parts were no longer available for cheap, so there came a crossover, where a newer car was needed. We also had a 1975 Toyota Camry, which we finally gave away to Goodwill in 2005. It lasted another year, then the new owner trashed it because she ran it out of oil. We saw it along the road, abandoned, looked into the hood, and saw the obvious. It made me cry. Our regular family car, 1995 Honda Accord has 275K on it, and still going strong. I ran an estimate, and these cars have saved us over 2+million dollars, over buying a new car every year.
Who buys a new car every year bro?
How buys a car every year for life?
Nobody buys a new car every year. Stop embellishing and exaggerating. If you bought a brand new f150 every 10 years it would only cost you $150k over 30 years. And that’s if you don’t sell the 10 year old one for anything but realistically a 10 year old f150 still going for 20-25k.
The first year they made the camry was 1983...
Being an engineer, you were more likely to have mechanical sympathy, and address issues like servicing and checking and changing your oil regularly. I have seen engines where the funny red light which sometimes illuminated, turned out to be the oil light, and needed 4.5 litres to top up. That is just asking for misery. I have also seen a car which was so hot to the touch, that I needed rags to approach the bonnet. Inside the engine bay, the exhaust headers were glowing red-orange. Turned out to be zero coolant and oil. She said, I just need to get to an appointment, and drove off.
Couldn't help smiling in disbelief at not seeing any copper peaking through the bearing.
Great system and taken care of too.
I think as far as diesel engines go, operating under load is better for them than just daily driving. Pulling trailers around is keeping the engine running clean along with good maintenance. Same in Class 8 trucks, too. This driver understands his equipment.
I have over 400K on my 2007 Ram 2500 (5.9 Cummins). Most of those miles were on the highway, pulling a trailer. It's retired from long haul driving now, and carefully maintained for occasional hauling. I'm likewise retired, so my daily drivers don't get more than 1500 or 2000 miles per year. It will be my last ever truck purchase, and is practically a family member.

Bypass oil filter was only used about the last 1/3 of its mileage.

Best truck i ever owned Praise GOD!!
My dad's friend invented an auxiliary oil filter and my dad allowed him to put one on my 1982 Rabbit diesel. I drove that car for 496,357 miles. The only part of the engine that was ever opened was the oil pan to plumb in a return line, and the valve cover to replace the leaking gasket. Sold the car to a diesel parts shop as a parts runner. The filter added 4 quarts to the system and changed the oil every 10k.
Those VW rabbits were great. I had a 79 gas 42 miles to the gallon. I knew the diesels to get 49
Big truck engine maintenance uses bypass filters. Oil is lab tested at regular intervals and topped up. Oil is very rarely changed because it’s perfectly good.
@aaron-dd5zr if I pulled in behind a semi I could get over 60. Ironically, I had a 2009 Jetta TDI and it got the same mileage as the 30 year old model. I also had an Audi A3 TDI that routinely got 50 and this was a rocket ship compared to the other 2.
Another masterclass on functions within a motor. Keep it up, Dave. These are classes I don't mind attending ! Every video has info of great worth.
Hello Dave's Auto Center. I think the lifters you want for your awesome engine builds are the eeze roll lifters by isky cams which use a bushing with oil lubrication groove design. They were commonly used by big daddy don garlitz on top fuel engines, I saw them on the engine build parts lists at don garlitz museum. Hope it helps
$1500 each wow! 🤯
@@philipmilsom9544 Actually that price is for one set of 16 lifters
@philipmilsom9544 Dave's machine shop only needs to manufacture their own similar lifter that's more affordable. I believe a set of lifters from isky is far cheaper than buying 1 at a time, call for pricing. If daves machine shop pressed out the lifter pin on a stock lifter, they could easily machine a bushing to fit the oem roller wheel and lifter pin. There's endless possibilities when it comes to creativity with a pro engine machine shop. I mentioned the lifters because they have the correct design dave mentions would be better than roller bearings, the rest is up to the creative people at dave's. One other possibility to extend roller life is to use a larger roller on the lifter to reduce roller rpm. I've seen some engine builders use a cam cut from a larger diameter core to achieve the same lift and duration with less transition onto the lobe to reduce wear on roller lifters. Theres lots of ways to deal with roller lifter wear.

Congrats on that impressive mileage. I’ll bet Cummins would be interesting in researching y items engine.
What sort of emissions problems, if any, have you had?
What sort of fuel treatment, if any?
What kind of oil?
Thankyou for the congrats, yea maybe Cummins would like to buy my truck even? It would take a lot of coin before that would happen.
Emissions problems i had around 2014 with the 3 converters in the exhaust plugged up at around 430,000 miles.
Put in a straight pipe and had the computer system emissions deleted and tuned for better fuel mileage and that was a great improvement in fuel economy, performance, reliability and cooler running engine.
Fuel treatments i don't always use but have used lucas fuel system lube, power service in white bottle, ATF, others i can't remember the name.
I also modified the fuel system to half inch line all the way into the tank with high temp hose and built a heated fuel system from engine coolant heating a remote mounted fuel filter using a CAT 1R-0750 spin on fuel filter.
I relocated the Dr side battery into the bed and then Put a aluminum pad where the battery was under the hood and built the heated fuel filter system on that and it worked better then i expected and tested flawlessly at -40 in cold winter night long distance trucking pulling new Campers.
I also have run waste oil in the truck at times with the heated fuel system but its not convenient now to play around with pre filtering waste oil were i live
but my truck can run it no problem.
Now i just stand beside my truck and spin off the fuel filter and spin on the new one the way it SHOULD have been from factory.
The oem fuel filter is nuts to get at having to remove the battery and stand on a toolbox and wiggle both arms in by the engine with a special plier + chemical resistance gloves to access...
Not a fun job especially in the cold of winter when the fuel filter plugs up..
I been in some scary cold situations and had enough that the next summer i built my heated fuel system to save my life and it was sure worth it..
Wish the manufacturers had the option to have a heated fuel system and a fuel pressure gauge in the truck while they are at it...
They don't care that much...
To this day a diesel truck is $100,000 give or take and you don't even get a fuel pressure gauge..
Diesels need a fuel pressure gauge just like an engine needs a oil pressure gauge.
When pressure drops you know its either the filter is plugged or the fuel pump is going out or there is gel in the line...
Engine oil was rotella T 15w40 a lot of the trucks life but i got the truck at 390,000 miles and kept using that brand of oil and lucas oil stabilizer and powerup metal treatment..
I later switched to mobil 1 0w40 synthetic ( using the same additives ) after finding tests that it was 1 of the best on the load bearing test bench.
Later Amsoil Signature series 10w30 tested better so i switched to that...
Also added the frantzfilter bypass oil filter that uses a toilet paper roll to clean the oil better.
I could go 4 times as long on my oil changes after that and it saved me time and money and helps the engine...
Back in Jan 2022 i lost my trucking job because some big shots thought i needed to inject some dna altering venom in my veins to continue trucking.
I said no way as i want to live and so here i am now still heathy with a healthy truck but no job and lots of debt...
Last oil change i did on the truck was jan 2022 using a jug of Lucas oil stabilizer and a jug of Amsoil signature series 10w30 and a jug of motorkote as an experiment and its thick but no problems and the oil is fairly clear still with only a slight tan color from new color...
Truck has hardly any rust for living in a rust belt area in Canada.
I oil up areas on the truck with wd40 GEL Lube and highly recommend all vehicles be soaked with that oil or Krown works to and my Brothers garage uses krown and its great to and creaps into areas better...
If you don't drench your vehicle with oil then rust will have the pleasure of destroying it for you at your own expense!!!!
Best thing is to drench a vehicle with oil from new on then once a year after that.
Oil in the rockers and frame inside and out, in cracks and crevices and inside doors but remove the panels and clean out any grime at the door bottoms 1st because it collects there over time.
Soak it when it new is the best ans it key.
Overall i was Blessed with a Great truck.
Proper Maintenance Extends life and that goes for more then just vehicles 🙏
@@Emory561 This was such a great reply. Believe it or not, I’d still watch a video on your truck if you explaining all that. I’d bet you’d get 20-50k views just naming it something like “Ultra high mileage Cummins. How long can it last?” Then put a camera close up shot of the odometer and a photo of the truck. Walk everyone through what you just said and show the filters and the tank you built.
People like seeing things that are out of the ordinary. A truck with nearly a million miles is pretty far from ordinary. If you’re worried about emissions stuff getting you in trouble skip that part.
I would like to recommend you looking into fuel bypass filters. Without knowing what kind of fuel pump you’ve got, it’s an amazing way of preventing an engine or injector failure. I am pretty interested in the S&S Diesel bypass fuel filter. They destroyed a filter and it survived preventing the shrapnel from getting to the injectors. That’ll save an engine death or 10k repair bill and it’s like 450 bucks and a few hours of time.
Okay now the response:
Thanks for taking the time to respond. It’s fascinating you are able to burn anything in the engine and the injectors without worrying about clogging.
Sorry about Canada going crazy and forcing vaccines. We had it too here in the states and it’s unacceptable. Glad Biden and Trudeau are out so we can get some new life in our spirits.
It’s also interesting you don’t trust Amsoil by itself without the stabilizer. Oil manufacturers talk about stabilizers being an impediment to their chemistry. Amsoil seems like it’s best without any additives according to their promo videos. I’m no expert so I wouldn’t want to tell you to change anything. It’s just a point of conversation.
I’m curious what fuel pump you have and if you’ve changed it. Don’t ever let the tank run dry. That’s apparently what kills CP4 pumps and destroys fords. As long as it has fuel apparently it’s a great pump. Who knows? CP3 doesn’t seem to fail catastrophically in the forums online. Either way a bypass fuel filter would completely eliminate this worry.
I haven’t heard of Frantz Filters but I’ve heard people say the toilet paper thing before. It’s pretty fascinating they use a roll of toilet paper. Seems like it works great. I would love to know how well it works when comparing to the Amsoil or Insane Diesel bypass filters. A roll of TP sounds much cheaper than a filter from them.
As for fuel additives. Seems like you didn’t need those as much. I wish we could get good data on whether they’re worth it or not.
I got an 08 2500 with 6.7 with a g56 6 speed. Good to hear mines only got 160k on it, what extra fuel filter system you have
Nice! Praise the engineers, mechanics and research scientists!
I have ran the FS2500 oil filter for 650,000 miles on a Cummins 5.9 24 valve. I have no issues with the motor except a few oil leaks. I still drive the truck daily.

Wrong... evidence proves if an engine runs and drives at operating temperature with less cold starts and warming up periods the engine will last much longer. this is why semi-trucks can last over a million miles. you herd the owner say "I haul campers".

I know almost nothing about diesel engines, but enjoyed this video. Learning new things all the time! Thank for the informative video.
This engine use case is interesting because the guy obviously did regular maintenance, plus he benefitted from very long duty cycles driving campers across the country (the opposite of stop and go). In addition, he also had that 1 micron filter they mentioned at the beginning of the video. HOWEVER, he did also say in an earlier video that he did idle the truck all the time. Remember he said he would regularly sleep in the truck on long trips and idle the truck overnight, contrary to what Dave said at the 16:15 mark.
To me this says that excessive idling in a vacumm is indeed bad BUT if you are doing regular maintenance and running the truck for long periods at peak (non-idle) engine temps, you can still prevent a lot of engine wear and carbon build up. Thoughts?
Agreed.
perhaps a egr delete and a more advance oil filtration system.
I wonder what brand oil he used?
its been scientifically proven engines last longer when the oil is at operating temperatures and not having to go through a warming up period with frequent cold starts like you see in a passenger car. if auto manufactures implemented oil heating to 160 degrees followed by pre-oiling before engine start then we would see engines lasting much longer. but who would go through a 20+ min sequence before starting?
@@ericmartin2470 Heating the oil also heats components, which reduces wear on start up’s . The cold and hot cycles are extremely hard on engines. A cold engine on start up has less clearance between components. Pre-oiling would be beneficial. Could we get people to plug their gas or diesel engines in to maintain temp?
Dave I watch a lot of your videos. One thing I see. Removing a steel oil pan with a chisel etc almost always damages or destroys the pan.
If you use some gas heat on the flange it softens the sealer and the pan falls off. No damage.
Keep up the good work.
Essentially, this engine needed a cam and lifters and would have been good to go for another 500K miles,. that bottom end looks great!
Yup !
So, he had an opportunity to save the engine and then replaced it eth a different used engine when he knew he should buy Dave's? Lol

I'm a electronics technician now. Retired from the USAF over 20 years ago, after 20 years of service, as an Air Craft Weapons Mechanic. Loaded bombs, missiles, guns, and kept the acft weapons system up and running, electrical and mechanical.
Then after retirement, put my skills to work for several copier companies. Xerox and a couple of other local companies. In one of the companies I did a lot of Canon copiers. We had one copier, a canon 6000 series. Never had a problem. Just the one. IT had parts that wore out, but they were designed to be replaced. This one copier weighed almost 2x as much as other 6000 series. Thats nearly 800 pounds. The copier is about the size of an average home washing machine. We joked about that one machine as being the prototype that got sold. And as you know, prototypes are usually built way better. then later, substandard parts are then put on the assembly line.
To see all that... my first thought was no way nearing a million miles. WOW. Thats got to be one engine where they used the same parts the prototype had on it. With parts like that on it, keep them on the engine. until they need to be changed. You might not ever change them.
You can use a ball bearing with a flat micrometer to measure a bearing's thickness, just accurately measure the ball bearing first, then subtract that from your measurement.
True, but that assumes the ball is perfectly round.
@TucsonDude a ball bearing is perfectly round, what are you talking about? Plus you measure the ball bearing then take that measurement into account when taking your final measurements.
@@donniev8181nothing is perfectly round. Don’t be obtuse.

@@Letsgobrandon827 lol
FYI: The oil was drained, it’s in the gray bucket on the ground behind Dave. Any oil that’s coming out now is what has settled in the oil pan since it was pulled out in October. Also , this engine is packaged as a core that has to be sent back to ford as what they consider a long block. In the summer of 2023 the ford dealer in Wyoming had to reseal the upper, lower oil pans, and the front and rear cover. Spring of 2024 the upper oil pan was leaking again, come to find out when the repair was done the first time the tech inadvertently stripped the bolt hole in the rear cover which caused the new leak. So the job had to be repeated with the addition of a new rear cover.
If your the owner what you use for the disel
@ could you be a little more specific please?
Out of curiosity what is your oil change frequency and what oil are you using?
What brand of oil and fuel additive did you use?

A long time ago now, I drove commercial charter motor coach out of Ohio. Our owner had about 120 coaches. Some were 6V92 and some were Detroit 60 series. (Yes, I am old). We all knew that those engines could easily go 1.5 million or more. But they were swapped at 500k. PM and passenger safety was first on the list.
I worked at Penske we had 100 Detroit diesels
Daylily put all the other motors to shame not great on horsepower or fuel economy but they were very reliable
not to forget the best sounding diesels
@@dsstaang new semi-trucks needs to meet EPA regulations put in place during Obama. this has had a detrimental effect on diesel engine longevity. the reason you'd see 2.5 million miles is because those truck engines spent the vast amount of time running at operating temperatures and not having to go through cold starts and warming up periods. the motor oil needs to be above 160 degrees to lubricate properly.
I put the Amsoil Bypass filter on my old Ram. It filters the oil down to 2 Microns. And I only run Amsoil full synthetic oil. Also use their diesel fuel additive
As a sewing machine mechanic, I replaced needle bearings with a bushing made by the manufacturer. Way too many failures with needle bearings.
Better efficiency but yeah less reliability from needle bearings. And i.m.o. bronze bushing thats can impregnate with oil will always be better long term than a roller
Generally when calculating life time of bearings there is a 10% failure rate used. Reason is that there are so many parts with individual tolerances. So you check the lifetime but accept failure.
Benefits are less friction - after 900k mls this is no failure, it is just wear due to concept.
Imagine telling a guy your needle bearings are bad....😆
I never realized sewing machine mechanics existed lol
@@Peterswarahedwhat's so funny about that ?
"oh man thanks for coming thats pretty neat that your engine lasted this long" then proceeds to bash the same dude for not shipping it correctly lmao

Also, the little interview was done 11/20/24, same day as the cp4 video, but I think the engine teardown took place on 12/31/24
Well....he did it wrong...that's that. Now anyone watching this knows too....
Harshly knows lol@@vincentcarrozza2334
Hes trying to save future people money.Also its on his website.
As an automotive technician for over 30 years, I have always made it the first priority for myself and my customers to always change the engine oil at the recommend intervals or before. Proper maintenance will greatly extend the life of your engine. Remember if you don’t do proper maintenance it will cost you a new motor or more and if you change your oil too often it will only cost you the price of the oil and filter.
That makes complete sense….if there was no other way! With the filter I use and oil analysis you can save your customers time and money for a minimal initial investment. This filter from Insane Diesel really is a no brainer for anyone that plans to keep their vehicle and maximize the investment.
As my late Dad always said "oil is cheap, engine parts are expensive". I change every 3k synthetic and often on my 2001 f150 supercrew it's 1000 because a yr has passed 😉 but yes oil and filters ..
I realize it’s apples to oranges, but I have 1,980,000 on a 2006 International 9400i with a Caterpillar C13 engine. It had an in frame overhaul at 1100,000 miles due to a head gasket failure. Since then, with the exception of one injector electrically failing, the engine has been flawless.
I use the FS2500 spin-on filters, Cat oil and fuel filters, and Rotella T6 oil, and the only fresh oil she gets is when the filters are changed every 20k. I finally had to change the oil last month at around 475,000 miles as the lab said it was time.
Since the engine overhaul, i think that’s only the second oil change. When the injector was installed last year, the tech at Lansing Cat commented how clean the engine was inside. Bypass oil filtration is a huge game changer!
Hopefully your comments will help people believe! Thank you! You can lead a horse to water but you can’t make him drink!
No surprise, older CATs are good
So cool to learn all this in my 50’s. In high school, I always had my head under the hood. Life took me down a different route but now I am spending a lot of time doing what I always loved. Just got done swapping out my 2002 7.3 L. I put an old motor from a well-maintained bus with 200,000 miles on it. The church I bought it from did regular oil changes. No EGR runs awesome.
Just incase some of you don't know he also used a Frantz Filter System to filter the oil which kept the sludge down and large particles out of engine.
1970's a roll of toilet paper as a filter.
I think it’s an Insane Filter. Same principle though, probably knock off from Frantz.
@@hanseich You ever seen a Frantz filter? If anything they vastly improved it.
Clint , of Custom Works, a 7.3 YT channel, already showed the data specs which filters are best on our diesels.
The AMSOIL “by pass” filter on their dual filter set up, is Unsurpassed, other filters can use , Donaldson BD7405, Baldwin B7039, Total purple filter, Amsoil EA099, Mobil1. on & on.
You’re Welcome.
All Fram filters are trash! Will never use a Fram. Had 1 that had a pinhole in the side, and engine lost oil pressure, it was a chevy 6.0 , thankfully the low oil pressure light came on n I stopped in time
Could only imagine what Bill Hewitt would say, that’s amazing how long that went as well as it did.
Love seeing tear downs on this channel!
Dave, you guys should’ve gone over the bypass oil filter setup in-depth and told viewers what the brand was and such. Maybe that’d be a great idea for another video on this truck/engine. It’s obviously a great product, and everyone in the comments is curious about them after watching this. I know you don’t make em, but it’d still be cool to shoutout a good product and tell us all about it. I guarantee you’re gonna have people interested in them after seeing inside that engine, so I hope you either start sellin em or tell people where to get em.

@@paulbennett274Awesome, I see it now. I couldn’t find it when the video came out so idk if it was there before or I’m just blind lol. I hope Dave does an in-depth video on the system in a video cause it’s obviously something that works and I’d like to hear more about it and how it looks mounted in the truck and everything.
Reason this diesel made it to almost 900k miles was because the engine worked non stop for the majority of it's life. Cold engine running, stop and go, and idling is what kills engines both gasoline and diesel even more so than extended oil intervals.
The secret behind all these high mileage cars, vans, trucks.
Frequent oil change, forget what the manufacturer's say, change the oil and filter every 3'000 miles.
The other thing that helps is not too many cold starts, this guy ran his truck for 12 hours a day, so most of the mileage was done on a warm engine and warm oil.
Any engineer will tell you, most of the wear on an engine is done in the minutes after start up of a cold engine. Treat her gently until you have her up to running temperature.
I guess the only problem with this statement is thatI the owner of this truck performed oil changes every 10-15,000 miles based on oil analysis.
So very true. Even bad engines can survive much longer, if they get some love and sympathetic attention.
A good quality engine doesn't need that. You just should know before buying what is good quality.
Nah the owner is in the comments he changed his oil every 15k miles and had them test it every time. They actually told him it was still viable but he changed it anyway.
@@cdurkinz But didn't he have a secondary filter fitted.
“Every move you make, every breath you take, I’ll be watching you.”
Yes, Dave, I agree! Creepy 😅
The song's about a stalker. 😉
The song is every tyrant CEO's fav.
The hate spewing over a 900k mile engine that literally needed a cam and lifters to be good again is absolutely ridiculous. Say what you want about the "flawed" oiling system, it apparently works just damn fine.
It's all snake oil salesman nonsense to get people worried and to buy their "fix".
I think it’s more of pointing out ways it could be improved. And he mentioned he’s seen many fail at lower mileages. Some people don’t hate, has nothing to do with emotion, other than passion to improve things, maybe every engine would last 900k with that kind of… “hate.” 🤘
but if it didn't have a "flawed" oil system, it might have gone 990k mi....
Some people are happiest when they're miserable.
the guy had a ton of after market upgrades he mentioned in the beginning that were all to make it last longer
Back in the day when I used to build two-stroke dirt bike motors, the lower rod bearing, and it was a needle bearing, it would always fail, & the needles would get sucked through the ports, and it would always end up chewing up the top of the piston. It would always happen on the real high horsepower KX80, CR 250, last one I did was an RM250. They would press the crank halves together, in the rod was a solid piece with needle bearing between the crank journal. I can't tell you how many cases I split to change the rod bearing in a 2-stroke dirt bike....
I love your channel Dave. Although I now work as an engineer, in the field of biomechanics, machines have always been my love. Sometimes that's why I stop by my old workshop and visit the old team and the new owner who was my young worker 20 years ago. We look together at what is on the table and what goes into processing, and we almost always end the discussion on the fact that today there are not so many bad engines, as there are many bad owners.
Dave, I congratulate you on a job well done as always (although I know there are days in our lives when it would be best if we stayed in bed that morning) and I wish your team and you much luck and success.
P.S. there is no going back now, stay good as you are.
@3:49 “every step you take, I’ll be watching you.” That’s correct, Dave. It’s a Cold War Song, not a love song. Very misused for weddings. 😅
You're a research and development gift to the world
As I understand it, Iskenderian Cams has bushed roller lifters, I do not know who makes it for them, but it is something to look at.
Really enjoyed the tear down and reading the comments on this engine. I think if I were this guy and could afford it, would buy a complete engine, so everything is new. I’m sure Dave will build a great long block but everything else has almost a million miles on it.
What I brought to Dave’s is what Ford Motor Company calls a long block. I would never bring something to someone the way “I” wanted to bring it, that would be rude and disrespectful. I bought a long block from Ford, it was shipped to the dealer on this exact pallet, and that’s how they wanted the old engine returned. During editing some things get left out! 🤷♂️

Just charge me more to take it off and give me an option to charge me more to put it on. Why get all pissy. You are in it to make money. You have the tools and knowledge to do it, why not just happily take my money and not be a little b*tch about it. Also I dont have a parts cleaner to clean my oil pan and intake, so I need your equipment to do that. That being said I like the videos and thanks for the videos
Oil pans easy to drop8mm Bolt's poor little princess in shop wanted to get home early to wax their hair bean bags
In Dave's case, he's generally dealing with other businesses, which are fully capable of stripping the block. Like he said, this engine was shipped by a mechanic. They should should know better. I knew the differences between short and long blocks, and complete engines before I was 10 years old. Shipping it full of oil was the icing on the oil cake. I understand your position, but businesses rightly determine what their needs are. They could have been more gracious about it for sure, but at base, you and that business were a bad match, and you should have used a more suitable one. As a locksmith, I've been asked to do things that were illegal, unethical, or just outside what was sensible and profitable for me to do.

Thanks Dave! Top notch content. Love this episode!!! Cheers from Motown/Dearborn
Was that truck deleted, I’m sure it idled a ton being that was his home but taking epa out of the equation resulted in that truck going that long with his stellar maintenance to help!
I’d bet it wasn’t. They can check for emissions stuff in some states, because the hot shot drivers are considered commercial.
I didn't hear Dave ask the guy about idle time, but he said he spent 12 hours a day in his truck, so I'd like to hear from him about his idle time.
Everyone wants to know about the brand of oil, but I'm more interested in the filter.
Subaru developed an oil filter that I used to use called a Trasko. It's a canister filter and you replace the element. The element resembles a roll of toilet paper, but it wasn't. It also had a super fine stainless screen that would capture metal flakes. The first oil change on my Fed Ex Ground Workhorse P30 had about five flakes of metal in it; I about filled my shorts. I added Lucas at my monthly oil changes and never saw another flake. I sold the the truck at over 300k miles and never had an issue with the motor.

Outstanding content and Channel ! Thanks for sharing this
As a gear head since I was a kid I was always told that if you do proper services on diesels you should get a million miles out of them and there’s your proof. What a great video !! First time seeing a diesel motor hit those miles with a tear down and showing that if you do the oil changes and do the proper precautions of taking care of a diesel motor that’s the out come. Love your videos Dave. You have a great crew as well. Take notes people !!!
I'm impressed . Almost 900,000 MI and those main bearings look perfect well I guess what really says that you really need to put a better oil system in and what the guy put in better stuff to keep your oil clean and your temperature is down and if it had better lifters that would be a million mile engine wow thank you Dave for putting such good videos out about diesels I had a 6.2 Ford on 85 f250 and I thought I maintained the engine really good I got 400,000 miles before I got rid of it I always put a bigger oil filter on and I had a dual rancor fuel filter system and I always added additives to my fuel and that engine always ran great it finally started to I had a head gasket go out and about $410,000 MI so I had to get rid of it but it was my favorite truck
It shows you how the maintenance program was done by the owner. And this guy not only maintained it well, but also respected his engine.
As I recall, this guy was doing 10k-15k mile oil changes with a bypass and oil analysis. Is Dave’s motors going to require him to change oil at 3k as it states on their website for warranty?
Dave is marveling at how clean the engine is, and at the same time telling people to cut their service interval in half. This thing was going almost double the recommended oil change interval and it’s spotless. But the guy was doing it the right way.
My hang up is Dave require proof of 3,000 mile oil changes for warranty. This is proof that this policy is out dated and not friendly to the customer.
Most people don't use additives like this owner did.
@ you aren’t wrong but that has nothing to do with the oil. It saved his CP4 pump for sure. But the bearings and pistons look awesome for an engine 1/4 the miles. His oil change interval was perfectly appropriate at more than 10,000 mile intervals. Is Dave going to honor his engine warranty at this interval or is he going to stick to the 3,000 miles as stated on their warranty page? That’s the question
@@mebordernoneya8484
The owner was always doing very long trips delivering stuff (he did say but I can't remember what he delivers). That in itself means that the engine was always running at highway speeds and under load. Any carbon build up under those conditions would be extremely small. Even if he did sleep with the engine idling (as he said he did) when he is back on the road again any carbon deposited from idling would be burned off in no time.
Dave’s engines are also emissions compliant you can’t tell me that engine was pushing through an EGR
@ Dave’s engines sells long blocks. Emissions has nothing to do with a long block other than being built with the right compression ratio, quench, and valve recession. Emissions all happen on equipment bolted to the long block.
Adding extra filter will always add life. Nice
Keep some of the rod bearings in an exhibition for customers and tell them the mileage with regular oil changings.
Put failed/scratched/worn out bearings of a low-mileage engine with bad maintenance besides them as a SHOCKER.
Some awesome quality work here, it’s great seeing people taking the time to properly diagnose a issue and work out a solution to resolve or avoid the problem, I’m from Australia I run a small mechanical shop but that’s probably one place I could work for! Finally some real experience
My old '01 F250 7.3 I bought new and sold to my friend in '05 is still on the original engine at 760k miles. He runs it hard, but he's meticulous with maintenance and runs Amsoil diesel fuel additive in every tank. Modern diesel fuel is garbage. Probably the best thing you can do for a diesel engine is add some lubricity to the fuel and keep the filters changed.
I twisted my Dad's arm to start adding a bit of power service every other fill-up on his 1997 7.3 and he hasn't stopped bragging about better mileage and running super smooth. You're right ..we have crap diesel anymore, these poor engines need extra lubricity.
The bypass filter, fuel enhancement and oil this guy used is made by INSANE DIESEL
back in the day up in LA, many diesel truck owners I knew used ATF in each tank of diesel, cleaned and lubed at the same time.
You can thank Al Gore for “dry” diesel fuel. He had the petroleum industry take out the surplus that lubricants the fuel. The supposedly low emissions regulations. Total and BS technology.
What I have heard, is that American Diesel fuel is run without any sulphur? That is a way to damage the engine and limit its life expectancy.
Dave is a master of his craft for sure
Dave, nettle bearings spread the load more than a bushing will, think about it you can't have a dedicated oil supply so the impact would be on just two areas of th4 lifter. The needles move around so the load isn't iin the same area every stroke. The total area covered would be less than the needles. I think they designed the lifters the best way, not the only way, but the best for a push rod engine. The best way would be with overhead cams. Push rods are for lawn mowers.
came to the comments to say this about needles vs bushings.
This isn’t totally true. Bushings apply the load to the film of oil. Needle bearing apply the load to the needles. There is a reason pistons and main bearings are bushings and not needle. If flowing oil is available bushings are better. If flowing oil isn’t available (such as a drive shaft yoke) needle bearings are better.
Agree - plain bearing lifter rollers would be drastically inferior
Great video! Really appreciate the thoroughness of you and your team.
Its not just maintenance. This man worked his truck. Diesels need to be run . Driving around town short 15 mile trips are what shorten the life of a diesel. Towing is great it burns cleanest.
Always great advice from the expert who knows engines. This is a great example of how proper care and maintenance affect a diesel engine. Thanks for making this video. It is an inspiration for those who care about their engine. Don’t idle unnecessarily and change the oil and filters with good quality products at frequent intervals! Simple!
Thank you!
To be fair, even roller lifters are meant to be replaced before 1m mile. The fact this engine lived this long is a testimony to the fact we can still build relable shit they just need to get rid of the cp4 pump and emissions junk almost every failure point on this engine was designed by bosch can't be a coincidence
I'm having a head rebuilt on my dad's 318 a Dodge Ram with 465,000 mi. Got a leak in the head gasket the day before Christmas. Only thing I've done to is replace the headlight switch the ignition switch an added the additive tribotex to the motor rear end and transmission at 420,000 miles.
Needle bearings must be reasonably durable. Almost 900k out of it.
The hardness, surface finish, and roundness of the inner sleeve, the outer sleeve, and each needle must be maintained to have a successful needle bearing. The shortcoming of these systems is the finite point contact between the needles and parallel surfaces compared to a bronze sleeve with oil film. The size of the needles increases or decreases rolling resistance based on lubricant, cleanliness, and metallurgy.
There's a reason needle bearings aren't used on crankshaft mains or crankpins. All that's necessary is to polish those surfaces fine enough to prevent any asperities from poking through the thin oil film in operation. Maintain the oil pressure and film strength, you have zero metal to metal contact. The oil fluid becomes the bearing.
the fact the needle bearings maid it that long supper impressive!!!! if my truck maid it to 500k miles id call that a major win!!! gasser mind you.
I have marine engines. I centrifuge my oil every 50-100 hours. The centrifuge returns oil to semi transparent, almost as clear as new. Because the engines are free of sludge, the oil never gets completely black. I test the oil once or twice a year. Before I started using a centrifuge I used a bypass filter. I get 2 or 3 times the service life between overhauls than others using the same engines in the same service. The biggest difference is in the sleeve and ring wear. But my bearings also look like new. Crankshafts don't wear. I haven't ground a crank since the 1960s. Clean oil makes a huge difference. I also drain my PU and run the oil thru the centrifuge. I like having people check my oil for their expression when the dipstick has transparent oil.
I'm anxious to use speed of air pistons.
SO YOU STILL HAVE CROSS HATCH IN THEM BORES THEN LIKE THE DAY THAY WAS HONED . NO WHEAR AT ALL .
@@MIKEmofit There's always going to be wear, but the cross hatching lasts 2-3 time longer and is usually the deciding factor for overhaul. Mostly 2 cycle, so I can see the piston and sleeve thru the ports.
How do you centrifuge? And what oil brand?
@@davidrosenbloom6652 All the diesels are plumbed in to a gear pump that sends the oil to a heated tank. Each engine pan has 2 valves for safety. After the oil is in the tank, it's pressurized and that pushes the oil to the metering valve on the centrifuge. The centrifuge separates out oil and water. The finished oil drains to another tank and pumped back to the engine. Usually the oil is centrifuged after a run while it's hot. It separates better. The dirt is lightly embedded in the bowl and isn't cleaned every time since the engines are clean. Final oil cleanliness is controlled by how fast the oil passes thru.
I drain my PU into a bucket and take it to the ship. There's a deck fill that goes into the tank. After the centrifuge the clean oil is diverted into a clean bucket.
I use Shell Rotella T4 in everything.
Marine engines were overhauled 12 years ago and had a bypass filter, so cleaner than the average engine when I started. Mains are Detroit Diesels. If I was younger, I'd put one in my PU.
Others use the same centrifuge for biodiesel, etc.
@@oceanmariner Has the oil ever been sent for analysis after the centrifuge process? I can see the water and debris are sufficiently removed from the oil but I'm wondering if the usual breakdown of oil hydrocarbon chains (and associated lubrication strength) are still occurring at rather normal rates for the use of the oil, in spite of removing contaminates.
coming from a ford tech, that is how ford sends most (LONG BLOCKS), pan, front cover, rear adapter, etc. some of those parts on certain engines are integral to the assembly, oil pick-ups and such. what you sell is closer to a short block with heads. I would put money on it that is deleted as well.
Exactly what I was thinking plus those parts protect the inners from damage and moisture... Dave's being so picky on certain things it could bring more issues.
It definitely has an EGR still; Dave refers to it when talking about the low amount of carbon trash on the piston head.
Actually, it probably doesn't have anything deleted as this guy has to have a DOT inspection every year in order to haul campers. Running all highway miles with a good diesel additive keeps the DPF in the best shape that a DPF can be in.
Yes, I'd like to hear the answer from the owner.
@salsuginusrex5196 you obviously don't know how things work, for example in CT where I live if your registered 10001 lbs you're exempt from emissions, if you think these guys are not exploiting every lope hole you are a fool
👍 Thank you Dave and crew, your presentation, knowledge, and professionalism is much appreciated. 👍
If you add his total engine idle hours of 4,714 and times it by 30 = 141,420 miles and you add his odometer mileage of 892,315 = 1,033,735 total miles on his engine.
Except idling isn’t mileage.
@@MudOilnGearsExactly, often it is worse!
@@MudOilnGearsit’s not, but….its worse on the engine then running. I was told!
What was the total engine hours?
@@twostroker56 19896 running hours, 4714 idle hours, total hours 24,610.
Ford: produces a 900,000 mile engine.
Also Ford: the 2.0 EcoBoost in my '18 MKC failed at 37,000 miles and the replacement engine failed after 5,000 miles. Religiously maintained. Suffered the notorious coolant intrusion issue twice
It would be interesting to know what oil was used and how often it was changed?
Probably Synthetic Rotella 15w40. Probably changed every 5000 miles. But considering the advanced filtering system, and road traveling without stop and go, might he have gone to 10k but I doubt it. Very impressive life out of a motor especially considering how hard he worked it. I would probably guess 5000 mile changes.
@@phil4986In the first video with the owner and Dave’s son Miles the truck owner said he did oil analysis routinely and based on how well the oil did he started with 5000 mile changes, then 7500 and I believe he ended up going at least 10,000. But it seems the key is that the truck ran 12 hrs a day every day towing travel trailers from coast to coast. The engine was always at full operating temperature with clean oil and fuel. I have an acquaintance who also towed travel trailers with his Ram 3 liter Ecodiesel and got 462,000 miles on the first engine and over 300,000 on the second before he moved up to a Cummins. Modern diesels need to be run, little idling and longer trips. City driving and modern emissions don’t go together. Look at Dave’s video before this one “Looking at CP4 at 900,000 miles.”

Amzoil with a bypass filter.
325k on my Mazda pickup.
Changed oil 5 times.
Engine was clean as a whistle and ran like a top!
Got tired of driving it.
Sold it after 14 yrs and 325K.
You mean to tell me that you changed oil 5 times in 325k miles? Are you stupid?
mishimoto trans coolers are no joke
I wonder how many times those injectors fired. Those bearings proved how important oil changes & filtration are. I would have NEVER thought bearings with that many miles on them could look that good. Think how many times that crankshaft rotated with all that pressure on it. Amazing.
that's proof that journal bearings work without any wear if everything is ok.
Keeping the oil clean, not necessarily changes. Bypass filter or centrifuging. Oil analysis will prove this out.
You know the reason for that, lubrication! The owner used good oil and short intervals. Plus he added on another oil filter.
wow the cinematography has stepped up. good work
Ain't no body gonna talk about the Toilet paper oil filter his friend built that the owner used from the first month he bought his truck? To get it almost 900K miles.
Dude! That’s what I’m saying. The latter part of the video should have been showcasing that system so the people can find it.
A company called a “Frantz” makes that style oil filter, and they actually sell a cartridge that isn’t off-the-shelf TP though you can still do that.
I use a filter by Gulf Coast that uses a roll of heavy duty paper towels. Works great. I drain and replace six quarts of oil from the filter and change the filter every 5-10 k miles.
Oil analysis always says the crankcase oil is good to run.
I usually change all 20 quarts of oil the bypass and full flow filters every 30 k or so. 25 years and going strong. 2000 7.3
Probably why the truck didn't last longer..
This man is the only man in the industry trying to improve quality (Less Profit). Every manufacture is trying to produce the worst product that they can sucker you into buying (to maximize profit at your expense). Companies have been disimproving things for at least the last 50 years.
Shows us that the weakest link will fail the entire engine. But with this mileage I would call it an overall success! 🎉
892k miles on og engine. Passed reliability check. I’m fine with an engine failure at this mileage.
@@Vikturus22 fun thing is that depending on your location and dimension for distance measuring the „barrier“ is different - million mls or million km. 🤣
With around 1.5 mio km and these clean journal bearings - really impressive.
I love how Dave is with his employees. He is awesome. I’m glad he bitches here and there but for the most part it seems like they love them.
I usually only idled when it was very cold or very warm, total engine hours(running and idling) 24,610 which is 19.2% idle time. Higher than I would like but necessary!
Must agree with Dave again. Solid bushings is the way to build it. Heavy duty truck-equipment engines have always used solid bushings for any high load bearing application. Surprised there isn't an aftermarket replacement for the cam followers. Newer HD diesels 12-16L are all overhead cam anyway which is a far better design than cam in block with pushrods. Heck, the auto industry figured that out decades ago.
The pistons, the rings and the rod bearings of this Diesel engine with 900,000 mi look better than many VW gasoline engines with just 100,000 km!!!
I WOULD LOVE TO KNOW HOW IT STILL HAD GOOD CROSS HATCH IN THEM BORES. THAT TO ME DOES NOT ADD UP . AT ALL .

Truly your best video!
Imagine if that engine had a startup pre-oiler.
or even delay in ignition/fuel injection, you crank engine 20x and after that, startup. with decompression system cranking would be 2x faster than normal and startup would be easier.
it would have made it beyond 1 million mile mark
it would be better if the engine had a pre-heater and heat the oil to operating temperature before starting. a pre-oiler would do nothing because engine oil needs to be hot before it starts working properly. Dave got this wrong as does most people.
Dave, excellent video! This is proving the oem lies to us on service intervals. Im glad youre taking the time to bring to light all the manufactures misinformation. THANK YOU.
The magic that made this engine last is the daily long term use without starting engine multiple times a day. He’s using this engine like a Peterbuilt driver uses one.
Correct. An engines internal wear is almost zero once warmed up. So all the number of warm up cycles matters. One one car I drove it 72k miles in one year. It's wear that year was nil compared to someone driving 72k miles in 12 years with zillions of short trips
First time I seen this guy, great video! Definitely checking out the rest. Well done!
The bots just love learning about diesel engine tear downs.
Yea....you gotta respect em for their willingness to learn outside of their wheelhouse.!
I guess they got tired of learning about aliens from Joe Rogan.
Woo-hoo! 900k!
What Dave is saying about lifter needle bearings vs bushings makes sense when you look at those rod bearings.
Not a good comparison. Look how much surface area the rod and crank bearings have. And most importantly, they are under full oil pressure at all times
The needle bearings experience a point load.
Theoretically the surface area of the bearing on the race is zero square inches. That changes of course on the quality of manufacture, the wear on the bearing, and the tolerances.
It is like a locomotive wheel. It is solid steel in a "perfect" circle, resting an a steel rail that is perfectly flat. What is the contact area....Zero square inches in theory.
"Theoretically" the contact between pin and bushing is also zero. The difference with a larger diameter pin in pin/bushing vs needle is more area is closer with the pin, more area for oil to suspend the pin. Catch-22 is the pin/bushing must have oil else contact is made. Needle bearing can roll with less wear during low oil conditions.
Ball bearings are even worse, especially if sizes aren't perfect, because then a lot of heat will concentrate on the largest bearings and then guess what? My experience is based on the front left on a Mazda MX5 race car where I ended up replacing them as a maintenance item every 6 months, thus getting rid of the failures.
Only motor I have ever seen in person was a 7.3 powerstroke I watched it roll over on the mileage odometer. Crazy for a 6.7 this is amazing
What brand of oil and how often changed is my question?
Synthetic Often, that's the best brand
Red Line full synthetic 15W-40. Has group V Ester base oil and a ton of additives
In the first video the owner said he tested his oil the first 2 or 3 changes, then put his changes out at 15,000 miles, and even testing that oil showed it was good enough to leave it in. But he changed every 15,000 anyway. That auxiliary filter must have worked great !
My 96 Z71 is closing in on 800,000, have always used Royle Purple, still running like new.
