Hi Bill, you likely don't remember me but you replaced head gaskets on my 6.4L. I was likely the last job you did in 2013 I picked the truck up late on Christmas eve. I was the old man you are talking about here. Had an H&S tuner. Always drove on setting 1 (Stock power) and for sure always towed my big camper in 1. But I was messing around with different settings and I forgot to change it back to 1 when I hooked up the camper. As I topped Mount Eagle I felt just a little sort of twitch. Stopped for the night and the next day coolant was low. Topped off and continued on the trip. Right about then I noticed the tuner in setting 2 and figured it out. That truck towed that big camper (17,000 pounds) out to western Montana, up to Glacier NP, back to Yellowstone, and back home, all after blowing a HG, I just kept topping off the coolant. Lots of people ragged on the 6.4L but I thought it had great power. Two months after I got it back from you a drunk old woman hit us down in Fort Myers and they totaled the truck. I got a new 6.7L and proving there is no fool like an old fool I have it tuned. Tune is STOCK POWER, EGR OFF, DPF DELETED. I think that is a safe tune. but I'm 80 now so if it blows it blows.
A clean mild delete tune that follows stock power levels is the way to go! Get rid of the epa engine killing crap, and don’t turn your truck into a race car; you’ll have reliability and still adequate power!
Hey bill!!! Awesome video!! I’ve got a 2000 F250, 7.3 with over 738,000 miles and she purrs like a cat. 3k mile oil changes, oem filters every time. You couldn’t offer me a brand new one to replace it. Thanks for all your content on your videos. Keep them coming!!
Thanks for the education, I’ve still got a 7.3 that I’ve always run at in the highest gear possible when not towing anything. I hope I haven’t caused any problems. After watching this video, I will run it to a higher rpm before shifting gears. Thanks again!
Your concise words on early cylinder ignition is my envy. Having begged with people to understand the multi-injection algorithm (program) PRIOR TO THE PRIMARY or MAIN injection is so key to knowing how these computers and the piezoelectric injectors can get the extra fuel in but cannot stop the physics and chemistry of compression ignition PARTICULARLY EARLY and sending that force down the rod to beat the bearing half and squeeze that oil film away damaging the bearing..... getting OWNERS KNOWING ALL THE FUEL IS NOT INJECTED IN "ONE SINGLE SHOT" is key for them to knowing that EVERY TUNER MANUFACTURER is managing BOTH Pre and Main Injection Programming... Thanks Bill for your Greatest Video Content for so many years....!!!!
Love these longer chats.. Thanks Bill. No longer a powerstroke owner, but still a subscriber (since the old 7.3 vs 6.0 video series!) and enjoy the education. If I ever get myself into a 6.0, itll come from Arizona to see you.
Engine lugging is what killed tons of Subaru WRXs and STi. People getting a tune and then mashing the go pedal in 4th gear at 1500 rpm causing insane amounts of detonation and blowing the ringlands off or rod bearing apart.
That's a thing with even stock cars these days,with small displacement relying on the turbo ,and then having crazy compression ratios like 10-11-12:1 on a gasser. Unheard of compression and boost levels and at lower rpms , if something is slightly off it's gonna pop. On a side note ,my manager at work has one of those little ram vans ,every time from a cruise when you tip into it you'll hear a little spark knock. That's kinda telling me a few things, the stock tune is aggressive , and keep doing that for 100k and watch a piston fry up.
My 2019 f150 had a faulty ethanol sensor (never ran e85 but it was a flex fuel gen 3 coyote) dealership said timing was advanced to the max. I brought it in for a weird rattle going in and out of 3rd gear, thought it was trans related. Nope, it was detonation so bad it sounded like a chain rattling. It was fixed under warranty (new ethanol sensor and Ford reflashed everything) ran really good but I just traded it in last week. I drove it like that for god knows how long, could have been all winter. Couldn't hear it unless the window was down
thank you so much for being an amazing person who provides so much to the automotive industry! you've always put honesty first and we all love it! cheers from texas
I can see why people want some more power if they are running an older truck, but yeah the new ones have plenty from what I’ve seen. To be honest, it gets really old when I’m driving to work each day and everyone always wants to race you, when I just want to get to my job in one piece then make it home the same way…
Me personally I think the people who tune these trucks are stupid but it's their truck they can do what they want with it and me being a mechanic I just charge them when I fix it 🤣🤣🤣 I work on a lot of these f****** tuned 6.7s but I am constantly fixing oil leaks and blowout turbos and f***** up fuel injectors and f***** up hp fuel pumps... If I'm being honest these idiots make me a lot of money 🤣🤣🤣🤣🤣🤣
Thank you Bill, for putting this in “Layman’s term”. I just got some Banks upgrades for my 2018 power-stroke. I think you explained everything i could have had questions about for the “non-deletion and deletion options”. It’s pretty much about the RPM’s!!
Ok so I kinda call bs. I work at a Ford dealer and I'm the main diesel tech. Been at the dealer since 04 as a diesel tech so I've seen them all. The real issue here is the epa. Most every truck we work on is bone stock. This is very very common for 6.7s to hammer the bearings or spin the bearings in completely stock trucks. It all stems from the epa wanting fuel milage (aka 6 and 10 speeds with 1400 to 1600rpm pulling on the highway), the epa mandate to pull all of the good things like zink out of the oil because it's bad for the dpf. And then we have the dpf and scr systems that make these things breathe through a dirty straw. I've seen way more issues with main bearings from oil type than any tuning. Yes don't get me wrong tuning can kill any engine. But in the 6.7 tuning is such a small spec on the map compared to what's actually killing the bearings.
Thats why I lock out the higher gears when I have a big load behind my 6.7 Cummins. Running a 30hp tune from a smarty and never run the higher tunes as they all start messing with injection timing to get power and that's not good for longevity.
Great video, I'm originally from the Pacific Northwest true diesel truck land. Moved to Phoenix about 18 mo ago. The heat down here is tough on my 95' F250 Powerstroke. I'm a CM for a large home builder so in the summer we spend hours a day in our trucks. All the idling is really hard on bearings I noticed one day my oil pressure was lower than normal. Still in a safe range but not high like usual. 250,000 on the truck and found my oil cooler was leaking. There's a video on a new 6.7 that had very low miles but approx 5,000 hrs of idling! Oil change history was good for the miles but the bearings were toast! Bottom line know your truck and don't abuse it.
Thanks for this explanation. I recently had my 6.7 tuned just to support the 2015+ turbo (mine's a '13) and I've been having frequent regen problems, even after a full flow test certified DPF cleaning. I decided to upgrade the turbo since the exhaust manifold studs started popping off and have read the stories about the early year turbo failures and wanted to bulletproof the exhaust system. The torque converter locks up earlier and shift points have been changed. I'll be sure to check if it's lugging too much or just try to keep the rpms up and see if that helps with the regen intervals. I'm to the point I may need a new Powerstroke doctor to fix it up since the shop that did all this work wants to avoid any responsibility...
As a ford dealer tech that mainly fixes the diesels I can’t agree more! A good economy or towing tune is good for a diesel but having some racing or aggressive street tune can destroy it in a matter of minutes.
Very good video Bill. People don't realize that the whole time the engine is running it is trying the shove the crankshaft right through the oil pan. All you're doing is multiplying the leverage when you get too crazy with fuel, timing, and overboosting past the limit it was designed for. Very good video.
good info on the rpm range for the 7.3l..... ill stop lugging it from now on!! Would really like to see a video describing driving habits and methods for the PS engines just like this tip on rpm sweet spot. Tips and tricks for higher mileage and longevity.
Pushing the engine harder than intended is always a gamble. In my tuned vehicles I send an oil sample in every couple of oil changes to track what its doing. Keeps my mind stress free that there is no forbidden glitter or reynolds brand bearing foil going on.
I have a 2011 6.7 150,000 and still even has stock turbo but is deleted and a sweet and simple tune nothin crazy I hate rolling coal and thing is a champion gets 18 mpg in the city with a 4.5 lift and 35x12.5 love the 6.7 and can’t imagine hauling with anything else, great video tho man I enjoy your information
Damnit... Guilty of this on the ol 03 7.3. I don't lug it hard(4r100) but I do drive at low low rpms. And I run the third, from the all out tune. My bearings gonna slip out in the middle of the night, sneak in the house right into the ol bedroom, and put it's shavings in the toothpaste and on my TP likely if I don't knock it off I feel. Im praying to the Ford gods to release the bad juju I've imposed with this "hammering" and let me spin it for another few hundred thousand miles. She runs like a top at 296k, still on factory injectors. Starts at -2 like butter too. Crazy how it works when you maintain them. Fresh ZD-11's and a stancore relay, probably better than new. Thanks for the info, it'll probably save me a small chunk for a good while.
Note: when towing if not on flat and level the the cruse control can over load the mains they will rotate and then no oil to rods. Have seen non tuned engine failures. ( Ford senior master Tec.)
My 2000s trevan had a switch on the turn signal lever that if the vehicle was either hauling heavy or towing one was to Preston switch. My guess was that the system raised the RPMs at which the transmission would up-shift to the next gear in order to keep the 4.3L V6 Virtec engine from lugging.
Excellent information. Not a Ford guy but what he says applies to all brands. I blew up a mildly tuned 6.5 Chevy by lugging it while towing. Now I have one with a better turbo and more fuel that I can tow much heavier with- but I keep the rpm above 2200 at all times (usually 2500 and up).
Good information here. Good, clean, proper tuning can make a world of difference on your diesel engine. Improper tuning can kill it in record time as well.
I wish I had went to work for this man when he put the million mile shop truck video years ago! He knows what he is doing and why the machines do what they do. I will never forget, "Too many burnouts in the cauldasack?", He is up on everything in his business, ladies and gentlemen, you want the best advice? 🤔 He is going to give it to you straight forward and bluntly with no sugar folks. Great evening to you all and enjoy.
Even the new 6.7L (stock tune) with the 10R140 (stock tune) lugs when shifting from 4 - 3 when in tow mode (1500 rpm). Sucks. Forces you to hit manual to force a downshift to raise rpms.
More fuel and timing with the tuners=more force on the bearings for longer periods of time. Not to mention those injectors are injecting 3, 4, 5 times on every compression stroke.
PCP - Peak Cylinder Pressure. Timing affects it, as does fuel rate. Every engine is designed to a PCP target, and nearly every tuning change bumps PCP above that limit. Engines are also designed with Safety Factors for the individual structural components. Some of these are easy to add extra margin to (block), but others have a lot of competing targets (con rod wants to be as light as possible, so it has a smaller safety factor. Head needs to be cooled, so it can't have a large factor of safety because wall thickness competes with ability to cool it). There's always a "fuse" in the system, typically the head gasket (6.0 lifted the heads and puked coolant out of the reservoir). But if the fuse is elsewhere (as in the 6.7), the failure mode can be more severe. 6.7 is robust structurally, but (as you expertly pointed out), the combustion force can literally squeeze the oil film out from between the bearings and crank journals, resulting in metal-to-metal contact just like a dry start (except under full load). The only way to increase capacity in the bearing is to make it wider. And bearing area is another tradeoff - more area requires thinner crankshaft webs (wider bearings) or a heavier crank (journal diameter increase). So the solution to achieving more power safely is to increase the area under the combustion pressure curve, without increasing the peak pressure above the limit.
I never owned a power stroke engine. I really appreciate this u tube channel as I believe they are very good at what they do ..I remember many years ago in the forums for what that's worth about timing and the effects on bearings , I run more timing in my old diesel as it gets better mileage. I was also wondering about the wrist pin bushings ect . These things are I assume based on the size of the components and the load imposed on them . Timing can also stress the head gasket to a failure... i alway like to let the old engine get up to temperature before i load it up . Thanks for the videos and the information
Love the explanations, I work on Freightliner's and such. We are seeing many many deletes or tunes on trucks because of the cost of repairing emissions. But the damage to the engine because of over fueling due to bad tuning.
@@michaeldunagan8268ell no. Considering just the new engine of a new 6.7 PSD is like 20 grand, I'd imagine they'd total the truck on purpose before that happened. I know I would.
Thanks for this information as I am that older guy with a 6.0 and a tune. I use the tune for good fuel economy when running unloaded and switch to a mild tow tune when needed. I have the manual transmission and tend to shift early courtesy of those years behind a Detroit diesel 🙂. Time for an old dog to learn a new trick and shift a bit later and keep the revs up.
I have a 2012. And I refuse to treat that truck like a race car. I just beefed up some of the weaker components. I.e: turbo, cold side pipe, ccv delete, disaster prevention kit, s&b cold air and a few others. Truck runs great no matter what I’m doing, cruising or pulling. Only tuning I’ve done is for the larger tires. It’s plenty powerful without adding anymore.
Larger tires without compensating the extra diameter of the wheel assembly and the axle or transmission brings the vehicle closer to the lugging range as larger tires act like shrinking the ring gear relative to the pinion gear.... I'm just saying....
Following I used T6 15w on my ‘12 but was advised to use 5w40 on my ‘15. I can see it in cold Indiana weather. But I pull heavy everyday but no tune. Yet I’m on the fence.
I've been running 15-40 since I bought my 6.7 2 years ago. It's got 175k miles on it. Run it all year long even when it gets below freezing. Never had an issue
I’m running the Banks Derringer programmer on my ‘19 F-450, with 2 gauge pods monitoring all the temps. I like that it is adjust on the fly. More power = lower fuel economy. Only time I turn it on is getting on the highway or running up some big hills, when I’m pulling my 20k toy hauler, or I have a heavy load on my flatbed trailer. Has plenty of power in stock setting for most other situations. Also gets best mileage in stock setting. Best thing I did for fuel economy was put the Ram Air system on it. Gives me 10%-15% better mileage.
Don’t turn the power up when towing. That was the main point of the video. Ignition timing at lower rpms… Be sure to keep it around 2000-2200 rpm when going up steep grades.
I absolutely agree Bill. I've had my 2015 6.7 for 6 years now. It's been deleted since 2016. Mild tuning, but always found the trans wanted the highest gear possible all the time. I run it in tow haul 90% of the time cause it just seems to run better in those higher rpm ranges. Love your content man, keep it coming.
What tuner did you get? I'm having a hard time choosing the right one. I want power efficiency and mpg only and of course let it breath better ya know.. I want one thats safe where the tuner knows what they're doing. Not trying to run 300hp just help the engine.
I have an 11 that does the same thing. Was thinking about getting a tune with a trans tune to try to fix that. It’s actually annoying to drive I prefer my 6.0 as far as shifting goes haha
I got a 17 f250 6.7 well maintained been deleted for about 3 years now and never had any problems I’m running a mild tune just wanted to get that junk dpf off of it runs a lot better than stock in my opinion to each their own
After reading the problems on youtube I'm afraid to delete my truck now. I have a Ford F250 2015 6.7L with 46,100 miles on it. I don't drive it much but when I do, I drive it till it gets hot. I use a OBDII and monitor when it goes into regen mode and I drive it till it deactivates and continue after it deactivates before returning home. The dealer always changes the oil and use's Motorcraft 15w40. I love the truck. Once a year for veterans day I trailer / haul my jeep for a parade.
Almost 50k miles on my 16 6.7 fully deleted and tuned, with 25k of that being full bolt on with non-vgt turbo swap, mpd piping and swap kit, airdog lift pump, etc. Shes been absolutely flawless for me. Tuning does not kill these trucks, the idiots behind the wheel do. Treat it like a truck, use the proper tuning for what youre doing, and be responsible. Also its a V8, dont be afraid to rev it out a bit, youre gonna do more damage trying to lug it at 1800rpm than letting her shift at 3000 to alleviate cylinder pressure.
Hi Bill, this is some great information you are sharing. I have a ‘17 6.7 but I’m in the peoples republic of California so no tune for me lol. Good to know that this engine is happiest in the 1800-2200 rpm range. I started using archoil last year when I found your UA-cam channel. I’ve only got 53k on the truck so I’m hoping to get as many trouble free miles as I can. Thank you so much for your great advice and additives.
I have a 13 6.7, and a 32' 5th wheel. I love the selective shifter because when I hook up to my trailer I loose 5th and 6th. I try to curse at 2000, and down grades I run 2500 to 3200. Seldome use brakes, even living in the mountains of Arizona. I recommend this operation to everyone. Never tow on O.D......
@@willc5512 so do I in Texas without all the crazy regulations… people are leaving your state in droves and moving to be free in the Great State of Texas! 👍🏻
With the 6.7L, is the design itself not also an issue? From the much narrower and smaller rods (Edit: The later model ones seem to be more reasonable as far as size) it seemed as though Ford was banking on the injection strategy to keep the peak cylinder pressures down by spacing out the combustion over multiple injection events. Since the pressures are lower, so are the forces, more like a gas engine with it spaced out over the work cycle rather than as a sharp impulse like old-school mechanical diesels. These seem to have fairly small bearings as well. Probably works ok with the factory tune and helps fuel economy by keeping the rotating mass down, but I can see why they would fail when tuned more like a traditional diesel. In a way the bottom end is somewhat like what you would see with a gas V8.
Yeah but whats the torque of the cat? The rotating assembly is probably twice the size of the 6.7 ps. Just because it makes the same hp doesnt mean its made the same. Thats like comparing a tractor engine to a truck engine. They are made different for different jobs.
Great advice! I guess I’m an older guy now… driving trucks with Cummins or Cats you never ran higher RPMs, unless it was a Detroit 318.. then you hammered it!
The only Powerstroke I would consider building and tuning for power is the final edition of the 7.3 that ended in 2003. I currently have an '03 6.0 w/an '04 engine. The 6.0 and DPF Powerstroke isn't designed to be overboosted....and live very long. Economy tunes and Tow/Haul tunes can be more efficient AND powerful within the limitations of the OEM parts. It's the high-performance tunes that kill ALL diesels, especially the Powerstroke, due to its inherent design flaws. I'm not a mechanic any longer and am a retired Industrial Design Engineer. My discussions with International and Ford/Navistar engineers were very enlightening as to the flaws and WHY they exist. Suffice to say that marketing, sales, and the CARB/EPA were camped out in the engineering departments, making unreasonable demands that resulted in the product we were sold. Thank you for your insight.
FYI, there is no explosion in the cylinder during the power stroke. There is a controlled burn of the fuel and the oxygen in the air. What is left over is super heated expand nitrogen the piston squeezes the expanded nitrogen and pushes the piston back down.
I still have my 2003 7.3L 2 wheel drive, crew cab, long bed manual transmission. it's a pleasure to cruise cross country in. stock as far as i know and 204k miles. if i ever fix my 1983 f100 inline six 2 wheels drive short bed i may use her as a daily driver/grocery getter.
I ordered my 01_F350 from the factory and it will be a cold day in hell before I sell it. Most reliable vehicle I've owned in almost 60 years of vehicle ownership.
My father has done nothing but beat the crap out of his 6.7 and that thing has no metal in the oil nothing. I know this isn’t proven but I’m telling ya. My father deleted and got it tuned at 80k miles and that suckers pushing 200 and strong as hell. These 6.7s are tanks when you keep them maintained overall just a much stronger 7.3 in my opinion power wise
As a small business owner myself that statement you said is so true about one day we’ll be looking for bankruptcy attorneys in the phonebook and then all the sudden a job comes through the next day never know what’s gonna happen
What are your thoughts on the new fuel water separator/secondary filter that SPE came out with last week? It uses CAT filters and replaces the stock unit in front of the tank.
Cylinder pressure 101. I find the stock scorpions are damn perfect bone stock. The only thing I would suggest is tuning the trans shift schedule to lower dynamic cylinder compression...and an aftermarket lift pump and absolute 2 micron cat filter system.
I was taught that a diesel should be near the governor on hills and not flat footed. Pick a gear that will allow some acceleration. But that was on old stuff.
it’s ALL ABOUT the powerband 💪 my little Detroit 500 60 series likes the rpms pretty high. water temp is like 160 rolling 62 mph at 2100 rpm old is gold baby 🤗
We have a 6.7 at the shop now. This is the third ive seen. Same problem just a little worse. It spun 3 main bearings and 4 rods. It is stock, not tuned. I think the stock programing is also to blame. They want the rpm low and converter locked for fuel mileage and to help control transmission temperatures when towing. I've talked to another shop that specializes in just powerstrokes and he is seeing alot of bearing failures around 200k miles or less. The other two trucks, one was tuned, and the other was a oil field work truck that was not tuned
Yes....trans shift scheduling and high end oil will be a big benefit. I honestly think they want these trucks dead by 250k so people buy new stuff. Look at the 7.3 gas engines. That oil system is a joke. I am at my fill with ford. They are turning me into a hater. I am an oilfield guy as well.
I drive a stock 2011 with 170k and Blackstone tells me I’ve got aluminum, probably from bearings, in my oil. I use good oil, change it regularly, and drive normally. I don’t know what else to do but wait for it to fail and get a long block.
great education for me watching this. is this the same reason why people see metal shavings when replacing fuel filters? hence why people are upgrading to the " disaster kit" on the fuel system?
Just had a 2011 F350 6.7 power stroke lock up. It was running when I brought it to the mechanic I told them it had a major oil leak and it was losing oil pressure and they started it up and ran it even though I told them such. The engine locked up on them and they call me and said your engine is seized and you need a new one. What do I do about this it ran when I brought it there they should have known not to start it. They should have pulled the oil pan or look at the oil cooler or something but definitely should not have started it since I told them a bunch of oil leaked out and I told them it was losing oil pressure.
Decades ago my brother ran an engine out of oil. He drove all the way home with like one quart in the crankcase. The next day the engine was seized after it cooled. Was in writing that you directed the dealership to take off your oil pan? I am surprised that you even on the Adept Ape channel that he started an engine that came in with an engine knock. I would think that since he's a Caterpillar technician he would bar-the- engine over to avoid any further damage to the engine by cranking it.
You need to put out more videos!! Apparently when you wake up in the morning, you piss excellence. It shows in every one of your videos. Everyone of your videos are perfect and dead on. I’m sure your work is the same.I really think you and your out look are refreshing! Keep up the good work.
I wonder how well these 6.7’s hold up to excessive idling? The work truck im in is a 2021 f-550 and it has 2800 engine hours and 20k on the odometer. We have to run them all day because of the cold. It was -41 the other night and the truck had to be left running all night. Nowhere to plug it in
Ten liter and larger Cummins and Caterpillar engines I know that the manufacturers warn against against prolonged idling of their engines. Both manufacturers do acquiesce but then they say only at 1,000 RPM or higher make sure that all the fuel is being burned in the combustion chamber. You might want to try 1200rpm in (-45°F) weather. You may not have to regen as much either by high idling than by slow idling.
People don't want to hear about the repercussions of their hot-rod tuning. There's no such thing as a free lunch. You're giving up longevity to achieve your marginal performance gains. These engines are worlds more powerful than their counterparts from 20-30 years ago. It's just never enough for some people...
What I don’t understand about high performance tuning or even an 80-120hp tune is what’s the point of tuning it if you have to stay out of the peddle often so you don’t kill the truck? You risk all that ecu money if it tanks or engine damage and you can’t even floor it all the time. Makes no sense
I've heard of this happening a couple of times in the Cummins for the Ram. Those engines pull so hard at low rpm but it is very harsh on the engine and causes the trucks to run so rich which is why they smoke so much more deleted compared to other trucks.
Both my companies rams are deleted one 5500 and one 3500. The 5500 is getting a new engine right now because it decided to delete cylinder #6 while pulling our backhoe a month ago.
I had a 6.2 diesel in my 1500 Chevy it started to run slow so I did the move the injection pump trick and it ran like a new one and even would puff a little black smoke when I would step on it.
Timing chain stretch will do that. Every 100K or so chain should be checked. My 86 with the 6.2 was converted to a gear drive which is nice. Can almost set it and forget it
I feel so guilty 🤦🏼♂️ bought my old 7.3 idi @385k and beat the crap out of it everyday for 2years and when she’s rolled over 400k we bumped that pump up and she’s still getting the beating 🥺 love her she’s the strongest old girl I know thank you international can’t believe she’s been beat of for 30 years and still wants more she runs so good I don’t even plug her n on cold nights and she gets up everyday 😊 not bad for ah 30 year old with ah drinking problem ❤
I really notice the engine in low RPM’s when I have the cruise control on traveling at 70 MPH under load and I hit a hill the cruise control will not downshift til it has gone 5 MPH below the set speed. I’ve begun giving it gas early to avoid the slowdown, didn’t know that was also bad for the bearing too. Thanks Bill and merry Christmas to the whole Powerstroke family!
Great video and explanation Bill! Is the 20+ motor less susceptible to this problem than the previous motors due to the revised rods, piston, and lower compression??? The new 10 speed loves to keep the rpms way down, I think the main caution would be when towing to be sure to downshift on long grades. Hope you’re doing well!
It's the same for the 20+. The rods piston and compression aren't really factors. Bearing size (width) where wider is better, and then just timing are what do it. Bill touched on it just briefly but the key thing of this failure is metal fatigue in the bearing itself. Take a coat hanger and flex it back and forth it will get weak and break, that's what is happening to the bearing. The hammering is flexing the bearing and after a while the metals in it start to fail. Can't even solve this with some kind of better oil, because it has nothing to do with lubricity or film strength. Even if an oil had perfect film strength all that means is the forces are fully transferred through the oil to the bearing bending it instead of pushing oil out. You could theoretically help this with a weaker rod because a weaker rod would flex and give more, absorbing more energy and reducing what gets to the bearing. But imagine the outcries if Ford installed weaker rods. The reason higher RPM helps Bill didn't explain, but it's because the flame front of combustion always has the same speed. With higher RPM the piston and rod will get farther away from being straight up and down at the moment of peak cylinder pressure because the piston is literally running away from the flame front faster. Bill is correct, when increasing the forces in the cylinder like this you either need to use more RPM to keep the rod angle appropriate, or less timing. The lesson here really is understanding that tuners go by the dyno and adjust their tunes based on the output measured by the dyno. What they aren't doing is tuning an engine and then running it for 2,000 hours at load to see if their tunes create failures in the long run. You'll see things like "early lockup" in tunes, run away. People like that because it really will make the truck feel and drive better and get better mileage, but it's also much harder on the engine's internals.
@@seijirou302 what are you talking about?! I’m mainly referring to your comment of “run away” to “early lockup”. Do you even know what that means??? Do you understand what that does? You were pretty easy to follow at first and then it started to ramble like you regurgitated something you heard. Then you make that comment and it’s obvious you don’t know what your talking about. Don’t give advice when you yourself don’t know
Great video, Big trucks and cummins drivers can lug a little more, because they are in-line and not V engines. gives them a lot more room for wider bearings = more surface area, more oil film area. I’m sure it won’t matter as much in stock form.

Hi Bill, you likely don't remember me but you replaced head gaskets on my 6.4L. I was likely the last job you did in 2013 I picked the truck up late on Christmas eve. I was the old man you are talking about here. Had an H&S tuner. Always drove on setting 1 (Stock power) and for sure always towed my big camper in 1. But I was messing around with different settings and I forgot to change it back to 1 when I hooked up the camper. As I topped Mount Eagle I felt just a little sort of twitch. Stopped for the night and the next day coolant was low. Topped off and continued on the trip. Right about then I noticed the tuner in setting 2 and figured it out. That truck towed that big camper (17,000 pounds) out to western Montana, up to Glacier NP, back to Yellowstone, and back home, all after blowing a HG, I just kept topping off the coolant. Lots of people ragged on the 6.4L but I thought it had great power. Two months after I got it back from you a drunk old woman hit us down in Fort Myers and they totaled the truck. I got a new 6.7L and proving there is no fool like an old fool I have it tuned. Tune is STOCK POWER, EGR OFF, DPF DELETED. I think that is a safe tune. but I'm 80 now so if it blows it blows.
The epa is killing the diesel industry
Who?
Exactly. I've seen this same problem in stock trucks. Best mileage is low rpm with the converter locked. Hammer down on the bearings
that's facts rite there
@@ShainAndrews epa and carb
Diesel particulates literally sicken and kill people, so maybe they should kill it.
A clean mild delete tune that follows stock power levels is the way to go! Get rid of the epa engine killing crap, and don’t turn your truck into a race car; you’ll have reliability and still adequate power!
But if you don't do your own tuning, how do you know who's tunes have too much timing and who's doesn't?
North coast diesel makes clean tunes.
all day long
Don't mess with your 6.7
Best description of this on the internet. I miss this guy, such a loss to our community.
Bill is a great guy. I never met him but love how real he is here. Solid and knowledgeable. Thanks for the info I learned alot here.
Hey bill!!! Awesome video!! I’ve got a 2000 F250, 7.3 with over 738,000 miles and she purrs like a cat. 3k mile oil changes, oem filters every time. You couldn’t offer me a brand new one to replace it. Thanks for all your content on your videos. Keep them coming!!
738,000 very nice!
Thanks for the education, I’ve still got a 7.3 that I’ve always run at in the highest gear possible when not towing anything. I hope I haven’t caused any problems. After watching this video, I will run it to a higher rpm before shifting gears.
Thanks again!
Did bill pass away if so im sorry to hear he is so highly intelligent and loved hos craft terrible if no one followed his foot steps
Your concise words on early cylinder ignition is my envy. Having begged with people to understand the multi-injection algorithm (program) PRIOR TO THE PRIMARY or MAIN injection is so key to knowing how these computers and the piezoelectric injectors can get the extra fuel in but cannot stop the physics and chemistry of compression ignition PARTICULARLY EARLY and sending that force down the rod to beat the bearing half and squeeze that oil film away damaging the bearing..... getting OWNERS KNOWING ALL THE FUEL IS NOT INJECTED IN "ONE SINGLE SHOT" is key for them to knowing that EVERY TUNER MANUFACTURER is managing BOTH Pre and Main Injection Programming... Thanks Bill for your Greatest Video Content for so many years....!!!!
Love these longer chats.. Thanks Bill. No longer a powerstroke owner, but still a subscriber (since the old 7.3 vs 6.0 video series!) and enjoy the education. If I ever get myself into a 6.0, itll come from Arizona to see you.
I got a 6.0 you can buy
Upgraded to a cummins???.....😁
@@michaellee5399 $?
Is Bill still selling his DealerProofed dualies?
I got a 6.0 you can buy too. Brand new motor 0 miles head studs is all is done to it. You just need a trans. 2007 f250 crew cab 15,000.
Thank you Bill! As a 6.7 owner this is great knowledge.
An Exhaust Temperature Guage will tell you alot about whether or not you are lugging the engine too. Thanks for the great videos Bill.
U can always tell by how an engine sounds and how an engine runs if your lugging it. As well.
Or watching the tach and knowing where torque peaks.
Bill you can retire sir. we want you to be happy
I don’t even own a powerstroke and I find all your videos very educational and good knowledge to have
Engine lugging is what killed tons of Subaru WRXs and STi. People getting a tune and then mashing the go pedal in 4th gear at 1500 rpm causing insane amounts of detonation and blowing the ringlands off or rod bearing apart.
That's a thing with even stock cars these days,with small displacement relying on the turbo ,and then having crazy compression ratios like 10-11-12:1 on a gasser.
Unheard of compression and boost levels and at lower rpms , if something is slightly off it's gonna pop.
On a side note ,my manager at work has one of those little ram vans ,every time from a cruise when you tip into it you'll hear a little spark knock.
That's kinda telling me a few things, the stock tune is aggressive , and keep doing that for 100k and watch a piston fry up.
Focus st too
My 2019 f150 had a faulty ethanol sensor (never ran e85 but it was a flex fuel gen 3 coyote) dealership said timing was advanced to the max.
I brought it in for a weird rattle going in and out of 3rd gear, thought it was trans related. Nope, it was detonation so bad it sounded like a chain rattling. It was fixed under warranty (new ethanol sensor and Ford reflashed everything) ran really good but I just traded it in last week. I drove it like that for god knows how long, could have been all winter. Couldn't hear it unless the window was down
thank you so much for being an amazing person who provides so much to the automotive industry! you've always put honesty first and we all love it! cheers from texas
To many guys think there 8000lb truck is there new race car leave it alone they have plenty of power stop the kill tunes
I can see why people want some more power if they are running an older truck, but yeah the new ones have plenty from what I’ve seen. To be honest, it gets really old when I’m driving to work each day and everyone always wants to race you, when I just want to get to my job in one piece then make it home the same way…
Me personally I think the people who tune these trucks are stupid but it's their truck they can do what they want with it and me being a mechanic I just charge them when I fix it 🤣🤣🤣 I work on a lot of these f****** tuned 6.7s but I am constantly fixing oil leaks and blowout turbos and f***** up fuel injectors and f***** up hp fuel pumps... If I'm being honest these idiots make me a lot of money 🤣🤣🤣🤣🤣🤣
You’re talking like a California liberal, it’s america we want that powa baby
Dude your a great teacher!! You have a great way of explaining stuff! I got a feeling a man could learn a lot just hanging around you.
I’ve seen main bearing failure on stock 6.7 powerstrokes countless times with stock tuning, stock truck. I doubt it’s the tune.
Thank you Bill, for putting this in “Layman’s term”. I just got some Banks upgrades for my 2018 power-stroke. I think you explained everything i could have had questions about for the “non-deletion and deletion options”. It’s pretty much about the RPM’s!!
Ok so I kinda call bs. I work at a Ford dealer and I'm the main diesel tech. Been at the dealer since 04 as a diesel tech so I've seen them all. The real issue here is the epa. Most every truck we work on is bone stock. This is very very common for 6.7s to hammer the bearings or spin the bearings in completely stock trucks. It all stems from the epa wanting fuel milage (aka 6 and 10 speeds with 1400 to 1600rpm pulling on the highway), the epa mandate to pull all of the good things like zink out of the oil because it's bad for the dpf. And then we have the dpf and scr systems that make these things breathe through a dirty straw. I've seen way more issues with main bearings from oil type than any tuning. Yes don't get me wrong tuning can kill any engine. But in the 6.7 tuning is such a small spec on the map compared to what's actually killing the bearings.
So which oil viscosity do you recommend? I've been using the 5w-40 rotella....so far so good.....
Thats why I lock out the higher gears when I have a big load behind my 6.7 Cummins. Running a 30hp tune from a smarty and never run the higher tunes as they all start messing with injection timing to get power and that's not good for longevity.
Great video, I'm originally from the Pacific Northwest true diesel truck land. Moved to Phoenix about 18 mo ago. The heat down here is tough on my 95' F250 Powerstroke. I'm a CM for a large home builder so in the summer we spend hours a day in our trucks.
All the idling is really hard on bearings I noticed one day my oil pressure was lower than normal. Still in a safe range but not high like usual. 250,000 on the truck and found my oil cooler was leaking. There's a video on a new 6.7 that had very low miles but approx 5,000 hrs of idling! Oil change history was good for the miles but the bearings were toast! Bottom line know your truck and don't abuse it.
If you get rid of epa, which has no right to make law you solve the biggest problem.
Thanks for this explanation. I recently had my 6.7 tuned just to support the 2015+ turbo (mine's a '13) and I've been having frequent regen problems, even after a full flow test certified DPF cleaning. I decided to upgrade the turbo since the exhaust manifold studs started popping off and have read the stories about the early year turbo failures and wanted to bulletproof the exhaust system. The torque converter locks up earlier and shift points have been changed. I'll be sure to check if it's lugging too much or just try to keep the rpms up and see if that helps with the regen intervals. I'm to the point I may need a new Powerstroke doctor to fix it up since the shop that did all this work wants to avoid any responsibility...
The frequent regens are from bad tunes.
As a ford dealer tech that mainly fixes the diesels I can’t agree more! A good economy or towing tune is good for a diesel but having some racing or aggressive street tune can destroy it in a matter of minutes.
Very good video Bill. People don't realize that the whole time the engine is running it is trying the shove the crankshaft right through the oil pan. All you're doing is multiplying the leverage when you get too crazy with fuel, timing, and overboosting past the limit it was designed for. Very good video.
good info on the rpm range for the 7.3l..... ill stop lugging it from now on!! Would really like to see a video describing driving habits and methods for the PS engines just like this tip on rpm sweet spot. Tips and tricks for higher mileage and longevity.
Any engine hates lugging. If for no other reason than the fact that the mains take more of a beating then than at any other time.
Pushing the engine harder than intended is always a gamble. In my tuned vehicles I send an oil sample in every couple of oil changes to track what its doing. Keeps my mind stress free that there is no forbidden glitter or reynolds brand bearing foil going on.
Just buy an oil filter cutter, or get a System 1 oil filter, and check it yourself EVERY oil change.
I have a 2011 6.7 150,000 and still even has stock turbo but is deleted and a sweet and simple tune nothin crazy I hate rolling coal and thing is a champion gets 18 mpg in the city with a 4.5 lift and 35x12.5 love the 6.7 and can’t imagine hauling with anything else, great video tho man I enjoy your information
Damnit... Guilty of this on the ol 03 7.3. I don't lug it hard(4r100) but I do drive at low low rpms. And I run the third, from the all out tune. My bearings gonna slip out in the middle of the night, sneak in the house right into the ol bedroom, and put it's shavings in the toothpaste and on my TP likely if I don't knock it off I feel.
Im praying to the Ford gods to release the bad juju I've imposed with this "hammering" and let me spin it for another few hundred thousand miles. She runs like a top at 296k, still on factory injectors. Starts at -2 like butter too. Crazy how it works when you maintain them. Fresh ZD-11's and a stancore relay, probably better than new.
Thanks for the info, it'll probably save me a small chunk for a good while.
Note: when towing if not on flat and level the the cruse control can over load the mains they will rotate and then no oil to rods. Have seen non tuned engine failures. ( Ford senior master Tec.)
My 2000s trevan had a switch on the turn signal lever that if the vehicle was either hauling heavy or towing one was to Preston switch. My guess was that the system raised the RPMs at which the transmission would up-shift to the next gear in order to keep the 4.3L V6 Virtec engine from lugging.
Excellent information. Not a Ford guy but what he says applies to all brands. I blew up a mildly tuned 6.5 Chevy by lugging it while towing. Now I have one with a better turbo and more fuel that I can tow much heavier with- but I keep the rpm above 2200 at all times (usually 2500 and up).
Good information here. Good, clean, proper tuning can make a world of difference on your diesel engine. Improper tuning can kill it in record time as well.
I wish I had went to work for this man when he put the million mile shop truck video years ago! He knows what he is doing and why the machines do what they do. I will never forget, "Too many burnouts in the cauldasack?", He is up on everything in his business, ladies and gentlemen, you want the best advice? 🤔 He is going to give it to you straight forward and bluntly with no sugar folks. Great evening to you all and enjoy.
Even the new 6.7L (stock tune) with the 10R140 (stock tune) lugs when shifting from 4 - 3 when in tow mode (1500 rpm). Sucks. Forces you to hit manual to force a downshift to raise rpms.
More fuel and timing with the tuners=more force on the bearings for longer periods of time. Not to mention those injectors are injecting 3, 4, 5 times on every compression stroke.
Isn't pilot injection actually helpful
PCP - Peak Cylinder Pressure. Timing affects it, as does fuel rate. Every engine is designed to a PCP target, and nearly every tuning change bumps PCP above that limit. Engines are also designed with Safety Factors for the individual structural components. Some of these are easy to add extra margin to (block), but others have a lot of competing targets (con rod wants to be as light as possible, so it has a smaller safety factor. Head needs to be cooled, so it can't have a large factor of safety because wall thickness competes with ability to cool it). There's always a "fuse" in the system, typically the head gasket (6.0 lifted the heads and puked coolant out of the reservoir). But if the fuse is elsewhere (as in the 6.7), the failure mode can be more severe. 6.7 is robust structurally, but (as you expertly pointed out), the combustion force can literally squeeze the oil film out from between the bearings and crank journals, resulting in metal-to-metal contact just like a dry start (except under full load). The only way to increase capacity in the bearing is to make it wider. And bearing area is another tradeoff - more area requires thinner crankshaft webs (wider bearings) or a heavier crank (journal diameter increase). So the solution to achieving more power safely is to increase the area under the combustion pressure curve, without increasing the peak pressure above the limit.
I never owned a power stroke engine. I really appreciate this u tube channel as I believe they are very good at what they do ..I remember many years ago in the forums for what that's worth about timing and the effects on bearings , I run more timing in my old diesel as it gets better mileage. I was also wondering about the wrist pin bushings ect . These things are I assume based on the size of the components and the load imposed on them . Timing can also stress the head gasket to a failure... i alway like to let the old engine get up to temperature before i load it up . Thanks for the videos and the information
Love the explanations, I work on Freightliner's and such. We are seeing many many deletes or tunes on trucks because of the cost of repairing emissions. But the damage to the engine because of over fueling due to bad tuning.
I wonder if all the purported or expected fuel that was saved, if any, is enough to compensate for the early death of their engines.....🤔
@@michaeldunagan8268ell no. Considering just the new engine of a new 6.7 PSD is like 20 grand, I'd imagine they'd total the truck on purpose before that happened. I know I would.
I believe Banks makes a safe tuner for completely stock trucks with mild bolt ons.
This is one of the best videos I’ve seen about 6.7s on the internet
thank you for speaking from all of your years of experience with honesty.
One of the best diesel videos I’ve seen in a long time I’m a 23 year old diesel tech you remind me a lot of my mentor when I was 17 at the dodge house
Thanks for this information as I am that older guy with a 6.0 and a tune. I use the tune for good fuel economy when running unloaded and switch to a mild tow tune when needed. I have the manual transmission and tend to shift early courtesy of those years behind a Detroit diesel 🙂. Time for an old dog to learn a new trick and shift a bit later and keep the revs up.
Yup
6.0 likes rpm
Cleans combustion and turbo
And sounds great
I have a 2012. And I refuse to treat that truck like a race car. I just beefed up some of the weaker components. I.e: turbo, cold side pipe, ccv delete, disaster prevention kit, s&b cold air and a few others. Truck runs great no matter what I’m doing, cruising or pulling. Only tuning I’ve done is for the larger tires. It’s plenty powerful without adding anymore.
Larger tires without compensating the extra diameter of the wheel assembly and the axle or transmission brings the vehicle closer to the lugging range as larger tires act like shrinking the ring gear relative to the pinion gear.... I'm just saying....
Do you know what weight oil he was running?
Bearing failure seems to be more common on trucks running 15w40, especially if they ever see cold temps.
Following I used T6 15w on my ‘12 but was advised to use 5w40 on my ‘15. I can see it in cold Indiana weather. But I pull heavy everyday but no tune. Yet I’m on the fence.
Closer bearing tolerances on the 6.7. 5w40 is crucial on these engines!
I'm running 5w t6 on my cummins especially here in the cold time of year but I might throw t5 in there when it gets hot
I’ve gone to Amsoil Signature 5/40. It’s expensive but better than having to replace a motor.
I've been running 15-40 since I bought my 6.7 2 years ago. It's got 175k miles on it. Run it all year long even when it gets below freezing. Never had an issue
I’m running the Banks Derringer programmer on my ‘19 F-450, with 2 gauge pods monitoring all the temps. I like that it is adjust on the fly. More power = lower fuel economy. Only time I turn it on is getting on the highway or running up some big hills, when I’m pulling my 20k toy hauler, or I have a heavy load on my flatbed trailer. Has plenty of power in stock setting for most other situations. Also gets best mileage in stock setting. Best thing I did for fuel economy was put the Ram Air system on it. Gives me 10%-15% better mileage.
Don’t turn the power up when towing. That was the main point of the video. Ignition timing at lower rpms… Be sure to keep it around 2000-2200 rpm when going up steep grades.
I absolutely agree Bill. I've had my 2015 6.7 for 6 years now. It's been deleted since 2016. Mild tuning, but always found the trans wanted the highest gear possible all the time. I run it in tow haul 90% of the time cause it just seems to run better in those higher rpm ranges. Love your content man, keep it coming.
A good transmission tune would do you good. A lot of people just tune the engine and never the trans
Yea with more power you kinda gotta accomodate with stronger trans and what not
What tuner did you get? I'm having a hard time choosing the right one. I want power efficiency and mpg only and of course let it breath better ya know.. I want one thats safe where the tuner knows what they're doing. Not trying to run 300hp just help the engine.
Same truck as you
I have an 11 that does the same thing. Was thinking about getting a tune with a trans tune to try to fix that. It’s actually annoying to drive I prefer my 6.0 as far as shifting goes haha
I got a 17 f250 6.7 well maintained been deleted for about 3 years now and never had any problems I’m running a mild tune just wanted to get that junk dpf off of it runs a lot better than stock in my opinion to each their own
Very good video.
You make very clear concise points.
Thank you
Thanks for the advice and your wealth of knowledge, Bill.
Very interesting listen. Thank you for this!
After reading the problems on youtube I'm afraid to delete my truck now. I have a Ford F250 2015 6.7L with 46,100 miles on it. I don't drive it much but when I do, I drive it till it gets hot. I use a OBDII and monitor when it goes into regen mode and I drive it till it deactivates and continue after it deactivates before returning home. The dealer always changes the oil and use's Motorcraft 15w40. I love the truck. Once a year for veterans day I trailer / haul my jeep for a parade.
Almost 50k miles on my 16 6.7 fully deleted and tuned, with 25k of that being full bolt on with non-vgt turbo swap, mpd piping and swap kit, airdog lift pump, etc. Shes been absolutely flawless for me. Tuning does not kill these trucks, the idiots behind the wheel do. Treat it like a truck, use the proper tuning for what youre doing, and be responsible. Also its a V8, dont be afraid to rev it out a bit, youre gonna do more damage trying to lug it at 1800rpm than letting her shift at 3000 to alleviate cylinder pressure.
Hi Bill, this is some great information you are sharing. I have a ‘17 6.7 but I’m in the peoples republic of California so no tune for me lol. Good to know that this engine is happiest in the 1800-2200 rpm range. I started using archoil last year when I found your UA-cam channel. I’ve only got 53k on the truck so I’m hoping to get as many trouble free miles as I can. Thank you so much for your great advice and additives.
I breathe alot better in Ca. So im fine with u having no tune!
come to far nothern cali its all tuned and deleted trucks up here lol
I have a 13 6.7, and a 32' 5th wheel. I love the selective shifter because when I hook up to my trailer I loose 5th and 6th. I try to curse at 2000, and down grades I run 2500 to 3200. Seldome use brakes, even living in the mountains of Arizona.
I recommend this operation to everyone. Never tow on O.D......
@@willc5512 so do I in Texas without all the crazy regulations… people are leaving your state in droves and moving to be free in the Great State of Texas! 👍🏻
Thanks. I'm a Cummins guy, but I learned a lot from your video.
Excellent discussion, Bill. Informative and educational. Thanks much.
Wow I just learned so much on this topic I’m just 20 minutes, this was awesome thank you
With the 6.7L, is the design itself not also an issue? From the much narrower and smaller rods (Edit: The later model ones seem to be more reasonable as far as size) it seemed as though Ford was banking on the injection strategy to keep the peak cylinder pressures down by spacing out the combustion over multiple injection events. Since the pressures are lower, so are the forces, more like a gas engine with it spaced out over the work cycle rather than as a sharp impulse like old-school mechanical diesels. These seem to have fairly small bearings as well. Probably works ok with the factory tune and helps fuel economy by keeping the rotating mass down, but I can see why they would fail when tuned more like a traditional diesel. In a way the bottom end is somewhat like what you would see with a gas V8.
Hey Bill that engine is making 475hp 1050 torque now look at a caterpillar 475 hp the bearings are twice the size 😀
Yeah but whats the torque of the cat? The rotating assembly is probably twice the size of the 6.7 ps. Just because it makes the same hp doesnt mean its made the same. Thats like comparing a tractor engine to a truck engine. They are made different for different jobs.
@@454budman Cummins laughing in the back.
Yea a 475 truck engine is gonna probably be set up for 1750 or 1850 tq usually. And there's the difference between light duty and heavy duty engines
Apples and oranges... dumb shit
And it's made to go a bazillion miles ,not 2-3-400k like a plain truck
Great advice!
I guess I’m an older guy now… driving trucks with Cummins or Cats you never ran higher RPMs, unless it was a Detroit 318.. then you hammered it!
The only Powerstroke I would consider building and tuning for power is the final edition of the 7.3 that ended in 2003. I currently have an '03 6.0 w/an '04 engine. The 6.0 and DPF Powerstroke isn't designed to be overboosted....and live very long. Economy tunes and Tow/Haul tunes can be more efficient AND powerful within the limitations of the OEM parts. It's the high-performance tunes that kill ALL diesels, especially the Powerstroke, due to its inherent design flaws. I'm not a mechanic any longer and am a retired Industrial Design Engineer. My discussions with International and Ford/Navistar engineers were very enlightening as to the flaws and WHY they exist. Suffice to say that marketing, sales, and the CARB/EPA were camped out in the engineering departments, making unreasonable demands that resulted in the product we were sold. Thank you for your insight.
Hey bill that would make a great T-shirt. " I tuned my truck and I'm going to diesel h***."
merry christmas tks for all you do
FYI, there is no explosion in the cylinder during the power stroke. There is a controlled burn of the fuel and the oxygen in the air. What is left over is super heated expand nitrogen the piston squeezes the expanded nitrogen and pushes the piston back down.
I still have my 2003 7.3L 2 wheel drive, crew cab, long bed manual transmission. it's a pleasure to cruise cross country in. stock as far as i know and 204k miles. if i ever fix my 1983 f100 inline six 2 wheels drive short bed i may use her as a daily driver/grocery getter.
Thanks as always for the information..that's why I have and will keep my 2001 f250 7.3..
I ordered my 01_F350 from the factory and it will be a cold day in hell before I sell it. Most reliable vehicle I've owned in almost 60 years of vehicle ownership.
As a owner of a new 2022 6.7 ps, I appreciate the info, keep rpm 2000!!! Ten 4
might want to check the Bosch CP 4 fuel pump while you have the engine out?
My father has done nothing but beat the crap out of his 6.7 and that thing has no metal in the oil nothing. I know this isn’t proven but I’m telling ya. My father deleted and got it tuned at 80k miles and that suckers pushing 200 and strong as hell. These 6.7s are tanks when you keep them maintained overall just a much stronger 7.3 in my opinion power wise
same thing for constuction. One day its dead, next day we need to hire more people.
Thank you from a long time ford mechanic!!!!
As a small business owner myself that statement you said is so true about one day we’ll be looking for bankruptcy attorneys in the phonebook and then all the sudden a job comes through the next day never know what’s gonna happen
What are your thoughts on the new fuel water separator/secondary filter that SPE came out with last week? It uses CAT filters and replaces the stock unit in front of the tank.
Cylinder pressure 101. I find the stock scorpions are damn perfect bone stock. The only thing I would suggest is tuning the trans shift schedule to lower dynamic cylinder compression...and an aftermarket lift pump and absolute 2 micron cat filter system.
So rpms being low while towing up a hill can be bad for a diesel?
Yes, especially if you’re running high egts. 2000 rpm is a sweet spot and would be considered quite low for a gas engine.
I was taught that a diesel should be near the governor on hills and not flat footed. Pick a gear that will allow some acceleration. But that was on old stuff.
it’s ALL ABOUT the powerband 💪
my little Detroit 500 60 series likes the rpms pretty high. water temp is like 160 rolling 62 mph at 2100 rpm
old is gold baby 🤗
We have a 6.7 at the shop now. This is the third ive seen. Same problem just a little worse. It spun 3 main bearings and 4 rods. It is stock, not tuned. I think the stock programing is also to blame. They want the rpm low and converter locked for fuel mileage and to help control transmission temperatures when towing. I've talked to another shop that specializes in just powerstrokes and he is seeing alot of bearing failures around 200k miles or less. The other two trucks, one was tuned, and the other was a oil field work truck that was not tuned
Yes....trans shift scheduling and high end oil will be a big benefit. I honestly think they want these trucks dead by 250k so people buy new stuff. Look at the 7.3 gas engines. That oil system is a joke. I am at my fill with ford. They are turning me into a hater.
I am an oilfield guy as well.
I drive a stock 2011 with 170k and Blackstone tells me I’ve got aluminum, probably from bearings, in my oil. I use good oil, change it regularly, and drive normally. I don’t know what else to do but wait for it to fail and get a long block.
Great info. Good to see still making informative videos.
great education for me watching this. is this the same reason why people see metal shavings when replacing fuel filters? hence why people are upgrading to the " disaster kit" on the fuel system?
Just had a 2011 F350 6.7 power stroke lock up.
It was running when I brought it to the mechanic I told them it had a major oil leak and it was losing oil pressure and they started it up and ran it even though I told them such. The engine locked up on them and they call me and said your engine is seized and you need a new one.
What do I do about this it ran when I brought it there they should have known not to start it. They should have pulled the oil pan or look at the oil cooler or something but definitely should not have started it since I told them a bunch of oil leaked out and I told them it was losing oil pressure.
Decades ago my brother ran an engine out of oil. He drove all the way home with like one quart in the crankcase. The next day the engine was seized after it cooled.
Was in writing that you directed the dealership to take off your oil pan?
I am surprised that you even on the Adept Ape channel that he started an engine that came in with an engine knock. I would think that since he's a Caterpillar technician he would bar-the- engine over to avoid any further damage to the engine by cranking it.
Great video!
Thank you Bill
I had the exact failer on my 2020 6.7
You need to put out more videos!! Apparently when you wake up in the morning, you piss excellence. It shows in every one of your videos. Everyone of your videos are perfect and dead on. I’m sure your work is the same.I really think you and your out look are refreshing!
Keep up the good work.
I wonder how well these 6.7’s hold up to excessive idling? The work truck im in is a 2021 f-550 and it has 2800 engine hours and 20k on the odometer. We have to run them all day because of the cold. It was -41 the other night and the truck had to be left running all night. Nowhere to plug it in
Ice Road Trucker?
We have them with 20 k idle hours. They eat up dpf
But run.
Ten liter and larger Cummins and Caterpillar engines I know that the manufacturers warn against against prolonged idling of their engines. Both manufacturers do acquiesce but then they say only at 1,000 RPM or higher make sure that all the fuel is being burned in the combustion chamber. You might want to try 1200rpm in (-45°F) weather.
You may not have to regen as much either by high idling than by slow idling.
People don't want to hear about the repercussions of their hot-rod tuning. There's no such thing as a free lunch. You're giving up longevity to achieve your marginal performance gains. These engines are worlds more powerful than their counterparts from 20-30 years ago. It's just never enough for some people...
I really like this guy, sounds very honest.
Always love your videos Bill!!
What I don’t understand about high performance tuning or even an 80-120hp tune is what’s the point of tuning it if you have to stay out of the peddle often so you don’t kill the truck? You risk all that ecu money if it tanks or engine damage and you can’t even floor it all the time. Makes no sense
I've heard of this happening a couple of times in the Cummins for the Ram. Those engines pull so hard at low rpm but it is very harsh on the engine and causes the trucks to run so rich which is why they smoke so much more deleted compared to other trucks.
Both my companies rams are deleted one 5500 and one 3500. The 5500 is getting a new engine right now because it decided to delete cylinder #6 while pulling our backhoe a month ago.
@@huskers1278 How many miles before it deleted itself?
I had a 6.2 diesel in my 1500 Chevy it started to run slow so I did the move the injection pump trick and it ran like a new one and even would puff a little black smoke when I would step on it.
Timing chain stretch will do that. Every 100K or so chain should be checked. My 86 with the 6.2 was converted to a gear drive which is nice. Can almost set it and forget it
I feel so guilty 🤦🏼♂️ bought my old 7.3 idi @385k and beat the crap out of it everyday for 2years and when she’s rolled over 400k we bumped that pump up and she’s still getting the beating 🥺 love her she’s the strongest old girl I know thank you international can’t believe she’s been beat of for 30 years and still wants more she runs so good I don’t even plug her n on cold nights and she gets up everyday 😊 not bad for ah 30 year old with ah drinking problem ❤
I really notice the engine in low RPM’s when I have the cruise control on traveling at 70 MPH under load and I hit a hill the cruise control will not downshift til it has gone 5 MPH below the set speed. I’ve begun giving it gas early to avoid the slowdown, didn’t know that was also bad for the bearing too. Thanks Bill and merry Christmas to the whole Powerstroke family!
Great video and explanation Bill! Is the 20+ motor less susceptible to this problem than the previous motors due to the revised rods, piston, and lower compression??? The new 10 speed loves to keep the rpms way down, I think the main caution would be when towing to be sure to downshift on long grades. Hope you’re doing well!
It's the same for the 20+. The rods piston and compression aren't really factors. Bearing size (width) where wider is better, and then just timing are what do it. Bill touched on it just briefly but the key thing of this failure is metal fatigue in the bearing itself. Take a coat hanger and flex it back and forth it will get weak and break, that's what is happening to the bearing. The hammering is flexing the bearing and after a while the metals in it start to fail. Can't even solve this with some kind of better oil, because it has nothing to do with lubricity or film strength. Even if an oil had perfect film strength all that means is the forces are fully transferred through the oil to the bearing bending it instead of pushing oil out. You could theoretically help this with a weaker rod because a weaker rod would flex and give more, absorbing more energy and reducing what gets to the bearing. But imagine the outcries if Ford installed weaker rods. The reason higher RPM helps Bill didn't explain, but it's because the flame front of combustion always has the same speed. With higher RPM the piston and rod will get farther away from being straight up and down at the moment of peak cylinder pressure because the piston is literally running away from the flame front faster. Bill is correct, when increasing the forces in the cylinder like this you either need to use more RPM to keep the rod angle appropriate, or less timing.
The lesson here really is understanding that tuners go by the dyno and adjust their tunes based on the output measured by the dyno. What they aren't doing is tuning an engine and then running it for 2,000 hours at load to see if their tunes create failures in the long run. You'll see things like "early lockup" in tunes, run away. People like that because it really will make the truck feel and drive better and get better mileage, but it's also much harder on the engine's internals.
@@seijirou302 what are you talking about?! I’m mainly referring to your comment of “run away” to “early lockup”. Do you even know what that means??? Do you understand what that does? You were pretty easy to follow at first and then it started to ramble like you regurgitated something you heard. Then you make that comment and it’s obvious you don’t know what your talking about. Don’t give advice when you yourself don’t know
Great video, Big trucks and cummins drivers can lug a little more, because they are in-line and not V engines. gives them a lot more room for wider bearings = more surface area, more oil film area. I’m sure it won’t matter as much in stock form.
I have a 99 7.3 with 400K and not tune. Ran the crap out of it everyday but it held up. I've never lugged any engine. They just don't like it.
The black smoke was killing me
Awesome video. Thank you.
As a commercial truck driver, we are told to lug the trucks for mpg. I rarely see 9ver 1400 rpm.
The opposite is true of the Detroits Bill. They Did Not like to be lugged, They liked to be reved.
