320,000 miles on my 2019 Cummins with no issues, but I've been running 10w-30 AMS Oil in my truck since day one, and I tow heavy every day. I also change my oil every 10,000 miles..
Awesome you're doing great. But I would switch to the 0w40 Diesel and go 7,000 miles max. It turns out that most oil analysis isn't telling the truth. I've had the same RAM truck for 23 years & never had anything go wrong minus a stuck auto lock and blown speakers. You can still make it to 4 or 500,000. But we like going forever. Oil still breaks down. And it's because of contamination. I'd rather run 0w40T6 and change every 3500 miles. Either way God speed, Baruk Hashem. 🇮🇱✝️🇮🇱
I may be a little ocd I have a 2003 5.9 I change my oil every 5000 kilometres I run 15 40 rotella since new 285.000 kms on the truck now it’s quite the debate thanks great video
@@coreymerritt7742 03 and early 04s are the cleaning running diesels ever made, HPCR, no egr. I had an 03 that I changed the oil 15-20 thousand miles(upwards of 30K km) and I sold it running great at about 350k miles (565k km). T6 5w40 fwiw. The oil literally, actually literally, didn't get black until 12-15 thousand miles, you could read the dipstick through the oil till at least 10k.
The HLA’s were specifically requested for the FCA engines by Ram in order to reduce NVH. Cummins obliged. But their commercial B6.7 is, as you already mentioned, still the traditional Flat Tappet. That should tell you everything you need to know. The wrong weight of oil (15w40) is definitely attributable to some of the premature lifter failures, but not all of them. There are deeper issues with the HLA’s in the 2019+ trucks and it’s a combination of supplier quality control failures and also design issues. Ram needs to scrap the HLA design and go back to the tried and true flat Tappet.
Well shame on Cummins for obliging to that request. I'm shocked at how many corporations operate with a scarcity complex. It's not like FCA would have dropped them over this. Cummins is what makes Ram HD trucks so enticing. If FCA were stupid enough to drop Cummins over this GM or Chevy would have been tempted to pick them up or it would open the door for a Japanese manufacturer to develope a HD truck.
I was running the rotella T6 5W40 in my 2021 3500 HO till about 85k miles and the truck has been great. I just started using 10w30 and the engine seems to operate better. It’s quieter and more responsive. I change my oil every 5,000 miles because I do lots of short trips and since I haven’t had a boating accident yet the truck regens often. Great video by the way!
@@oldsalt8011 pretty bad you even gotta say that 😂 "yessir im at 23k miles and I haven't had any issues yet!!"... The epa has to be deregulated and i hope trump does it.
Why does it break the brains of so many truck guys when it comes to oil viscosity? The first number doesn't mean you're running a 5-weight. It means it's thinner when the engine is cold but it's still behaves like a 40-weight oil when the engine is up to operating temperature. It's actually more protective than say a 15W40 when temps are very cold. The oil flows faster, gets to the top end faster, and protects a cold engine sooner than the "heavier" oil and as it reaches operating temperature, a 5W40 behaves like a 40 weight just like the 15W40 behaves like a 40-weight at that temperature.
People do not understand how a lubrication system works on an engine, oil pumps have a pressure relieve valve, and the gap between a Connecting rod journal / main journal and camshaft against their respective bearings is only 1.5 to 2 Thousands of an inch ( average human hair 1 Thousand of an inch ) So if you start an engine on a cold day with a 15W-40 oil, the pressure of the oil will open the relieve valve and dump the oil back to the oil pan and very little oil will make it to the top of the engine, your oil light or gauge will show pressure because most of the oil sending switches are screw next to the oil filters and not the top of the engine. That is the reason why the industry invented the multigrade oils best protection for areas with hot summers and cold winters 0W- 40 or 5W-40
Great video and great detailed explanation of the changes that have been made to the Cummins engines. It is disappointing to see Cummins has changed the valve train for the Ram trucks vs. the commercial engines. Cummins was great originally because the kept it simple and now they have made changes that have hurt their reliability.
Cummins Ram has had that 15,000 mile OCI interval since the 6.7 came out in 2007. I can’t remember what it was on the 5.9 common rail, but might have been 10,000miles.
@tammyspencer9786 kilometers or miles? That a big difference here! 12000klm is only 7456miles. 15000miles is 24140 kilometers...that's a huge difference.
@@onstar1869 maybe my memory is worse than I thought 🤷♂️. I’m almost certain I was doing it more often than what was called for in the owners manual @10,000 miles. I know for sure that I never reset the OCI without changing the oil& filter. My ‘14 & ‘17 definitely call for 15,000 mile OCI’s & I’m still doing 10,000. I’ve always used full synthetic (5w40) for my trucks after the 1st couple oil changes.
Thanks for the information Was going to pull the trigger on a new 2024 Ram 6.7 H O Not now I only put a few thousand miles a year on with a 4000 pound truck Camper Going with The Ford 7.3 Gasser now to avoid all these engine issues with these new diesel engines I too am a retired diesel mechanic and the last thing I want to do is work on a new engine
I run valvoline premium blue 5w40 and have 48k miles with zero issues. I live in WA state where it drops down to -5 during winter and 105 during summer.
I really believe that the key to preventing the hydraulic valve train failures is to keep the oil changed regularly! Keeping the oil clean and using a good quality oil is the key! I have my oil and filters changed every 5,000 miles, not the normal 15,000 miles recommended by the manufacturer!
I agree with your skepticism on the saved maintenance. I have a 2018 ram 3500 and just did the 240000km valve lash adjustment. $167 and that’s alberta prices.
$ 167 … If do it your self is even free* I know mine when is almost about time by the sounds of the motor specially after run it the whole day under a load .. ohh yeah .. you can hier that gap flapping at the top of the head cover
Rotella T6 5W-40 on my 2019 3500 with 35k original miles as of this post. I change oil at 5k miles, I want the best with extreme weather conditions Texas heat this summer high 120s - high 20 degrees in the Utah mountain trails in dec/feb. I spoke with Rotella field engineer about this years ago and he said Rotella T6 will get the job done!
50k miles on my 2021 light hauling and daily driving. 10w30 and Mopar filter every 7k miles. Oil analysis keeps saying everything is fine so not gonna worry too much, especially since it’s been deleted from new.
Except emissions gains are negated by reliability decreases, because cars themselves have a carbon footprint. The oil burned to mine their materials, the oil burned by employees driving to work to make them, the oil burned by consumers driving to work every day to save up money to buy them. Etc etc. If the EPA can't see that, they need to go bye bye.
Hi Getty. Since you have access to the regular tappets and to the updated roller engines, it would be insightful to measure the valve spring rates for each. I assume that in order for the engines using the rollers to hit their power/torque/rpm/epa numbers, they have to use way higher spring rates to keep the valves from floating too much. That plus the oil sludge issue would cause the cams to wear alot faster.
Really appreciate you sharing findings and getting information out to the community! As the owner of an 18 3500 with the 6.7L, I am interested in design changes like this (and the CP4) as the 6.7 Platform gets revised. I bought my cummins for the reliability - I dont mind wrenching, as long as my truck doesnt let me down...so I'm hanging onto my 4th gen! Reliable resources are getting harder to find, in a time when corporations are working hard to mask problem areas to save reputation. Love the content! Keep it coming!! Subbed! 🤘👌
I have a 21 Ram 3500 HO with 37,000 on it, and it's been error free. I currenly change the oil everying 6 to 8k mikes and have run Hotshot EDT in the truck since the 2nd tank of fuel. It's been a fantastic truck so far.
@brycelund4112 I agree. But I've seen so many people on UA-cam that have had all kinds of emission issues, warning lights, and failures on all kinds of engines with low miles. My wife has a 2021 Yukon Denali, and we just lost the 6.2 liter engine to complete failure because of CrankShaft bearings. Thank God it was still under warranty. It had 31,700 miles on it. Apparently, this was a known issue on some 2021's but we had no idea.
2023 SO 3500 with 73,000 miles, tow 10-20k all day every day, changing oil every 5-6k miles with Schaeffers synthetic 5-40, so far so good, no issues. Hoping it l will last at least 200k without issue
The people that service our trucks use shaeffers. No issues. I started getting a little lifter tick. She suggested Shaeffers moly additive, and it went away. 2022 std output with 100k miles. We change oil every 7-8k ish. My whole emissions just crapped the bed. The DPF plugged and split so did the EGR cooler.
@@joewright9784 emissions are my biggest concern, I don’t have a backup truck so downtime could be painful, looking into Enterprise for a truck rental if my truck goes down for extended maintenance
Hi, just got my 2022 HO 3500 out of the dealership for P2459 code. Believe it or not (sit down for this), the problem was....wait for it.....the engine air filter. Yep, mine had 2 glue strips on the bottom of the filter that created too much of a seal and the engine was basically 'running rich' causeing excessive regen cycles, and also messed up the MAF. Both replaced, and viola, no more issues! The old air filter was a Wix (great filter), but again, make sure (foot stomp) that there are no glue strips on the bottom.
106,000 Miles on my 2021, 2500, 6.7 Cummins. Bought it with 100k miles. Almost certain I have a lifter failure. I have the iconic driver side faint tick that I have seen indicates this failure (was not aware of that issue before my purchase, however I did notice that tick before purchasing). Getting it into the shop in a few weeks. After doing some research seems like OEM replacement is the best bet. After market kits for roller replacement require, lifters, push rods, springs, rocker arms, for the small price of $4,700. OEM is much cheaper. Flat tappet requires super stringent break in of running the truck at 2500 RPM for 30 minutes, and adding zinc additives to your oil, forever. For an engine not designed for that additive not sure if there are other part failure consequences when that is done. In my research I've also seen people talk about the keying on the lifter being a very low profile, potentially causing axial play causing the lifter to not be true perpendicular to the cam, thus not having a perfect role. The oil consistency, and oil change intervals may likely play in this failure as well. Sucks having a picky truck, and doing a cam job is ridiculous if you don't have a lift to push the whole body off of the frame. Will update with what the shop discovers and how much I'm in for.
@@stevenrossi8173 FULLY AGREE AND THE ADDITIVE PACK HE IS TALKING BOUT IF NOT DELETED CAN CAUSE SOME NASTY ISSUES WITH THE DPF, BUT SHIT IF DELETED HAMILTON ALL THE WAY! CURRENTLY I RUN HOTSHOT 10W30 BLUE DIAMOND AND HAVE NOTHING BUT GREAT SUCESS WITH HER BUT I CAN HERE THE LIFTERS EVERY SO OFTEN. THE HAMILTON IS TO COME FOR SURE AND AT THAT POINT WITH MISSING ITEMS ITS BACK TO HOTSHOT SECRET BLACKDIAMOND 15W40 WHICH ALREADY HAS THE GOOD ADDITIVES IN IT! ALSO WILL BE PUTTING A BYPASS FILTER IN JUST TO HELP ELEMINATE EXTRA MESS AS MUCH AS POSSIBLE!
GM and Fords 6.7 have been running Hydraulic lifters for years with no issues. The 6.6 L5P had some issues early on because they switched to a LS style lifter but all other years have been rock solid so hopefully Cummins can get the issues fixed a well designed hydraulic lifters can go as long as a flat tappet design if engineered correctly.
yeah i just got my first one , 2024 .. ive always wanted one , most of the older trucks have already been tuned and deleted , and have high miles and you just dont know if the maintenance has been properly done on them which is what drove me to get a newer truck , but i do wish they had just left things alone with the lifters , videos like this do make me nervous. I would never go 15k between oil changes personaly.
Considering all manufacturers are or have had valvetrain issues when we’re talking about automotive stuff I’m not surprised. I’ve got a ‘20 Ram, I’m not bothered by it. And 15k mile oil changes is nuts.
KTM 790/890 cam-itis (cheap metalurgy) I was surprised they had used solid lifters in the past. I'd be interested where the hydraulic lifters are made. (KTM has moved a lot of it's manufacturing to China) Good stuff as always, Alex
I change my oil every 12,000 kms on my 2021 Ram 2500. More often than called for but I’ve always done this (this is my 3rd 2500 with a Cummins). I’m at 155,000kms and have extended warranty to 160,000. Went for my oil change last week and apparently I have a camshaft/lifter issue. 🫤 at least dealer has been great, it’s under warranty but this video made me realize it’s likely a bigger issue especially the 2021 model year.
I listened to JB reviews he interviewed a Cummins mechanic with 30 years plus in the game, the guy had a good point and he said that all these problems started occurring when manufacturers started putting this lighter weight oil and making it required to run lighter weight oil in these diesel engines and if you look back over time, there was basic maintenance obviously with any motor in the world, but The Cummins motor didn’t have the issues that it currently has today and the only thing that’s really changed. Is the lighter weight oil?
5w40 isn't any lighter than a 15w40 at operating temperatures. But a 5W40 flows way better when the engine is cold and gets oil to the valvetrain much more quickly than 15w40. When the oil is cold, it takes a lot longer to pump hydraulic lifters up with a 15w than a 5w. Until they are pumped up, those lifters are hammering the roller against the cam lobes.
I’ve run 5w40 year round in all of my Cummins trucks going back to the 2000 5.9. I considered a newer one than my 2017 at one time, but too many issues popping up on UA-cam & forums. I’ll be sticking with the ‘17 for quite awhile & likely replace it with a gas truck if I have to at some point.
I don’t understand like how google says as oil heats up it looses viscosity (agree) also every engine I’ve had looses oil pressure as it warms up. My question is then how does a 5x40w (thinner oil) hold up as well than a (thicker wieght oil) when hot and have comparable viscosity than the thinner (5)w x 40w?
Alex, you are not some guy on the internet talking.... I like to think you know your stuff. Oil change intervals at 15k is too long imo. Wish the company would go back to the old style lifter you showed us. Sometimes the KISS principle actually makes since. Thanks for your videos, Greg from North Carolina.
I believe all of the engine components receive oil pressure at the same time during startup. A check valve ensures oil is held in the galleries, similar to the way that fuel is held in the rails. No?
6.7 PS has always recommended 10w-30 or 5w-40 syn. The advancement of engine and oil technology has made it possible to run lighter weights in heavier duty scenarios.
Yes concerned I have a tight oil interval 6-8k So will see I have 110k on a 22 ram And no issues to report so far actually runs beautifully and gets great gas mileage 10-12l /100k full emissions
I have a Ram 2500 diesel. Just clocked over 60,000 miles has a horrible lifter tick. I’ve taken it to three different dealerships and only one of them said that they can hear the tick the other two said that they can’t hear it which just pisses me off because it’s very obvious lifter noise. It has gotten way worse since it first started. It is very bad at a cold start. But the tick is there even when the engine is warm. It’s also got compression coming out of the intake on first start up.
So here is my thoughts. Tiller lifters in general are a failure point. We are seeing them fail in the Chevy gas engines with cylinder deactivation, we see it in the ram with the mds systems and now we are seeing it in the Cummins engine. U know the real reason I think they went to the roller lifter. The small amount of hp gains you get from using them. Just my opinion though but it would suggest that when it’s not in that bus engine. Can the roller lifters be reliable sure if you use high end oils and high efficiency filters but if that oil gets just a little gritty those lifters are going to start causing problems.
Detroit diesel used roller lifters in the 71 series engine beginning in the late 1930's. As I recall, they were trouble free regardless of the oil viscosity. These weren't hydraulic rollers, however. Maybe go to a non-hydraulic roller lifter?
The roller lifter is superior to the tapet. However the hydraulic lifter isn’t. Most large diesels use cam follower lifters and id support that any day.
2019+ show ~4x iron in UOA on average. Pre-2019 Iron was around 9 ppm. 2019+ is around 34 ppm. The lowest I have seen in my 2022 is 50ppm at 6k miles. 10k miles UOA showed 135 ppm. I have ran 10w30 T6 and 5w40 Valvoline prem blue. Best results have been with 5w40 and less than 10k oil changes. I knew to buy for CP3…but never thought to research a change in valve train. 75k on truck and runs great but the UOA…can’t unsee the excessive wear metals that are significantly higher than the pre-2019 engines.
I've got a 2022 3500 HO. UOA showed Iron 27ppm at 12,250 mi. Waiting on my 6K sample i just sent in this week. 5-6Kmi changes, Amsoil 10w-30 w/Amsoil filter. Watching and listening for signs of roller lifter wear/impending failure. Will likely go for the Hamilton flat tappet cam and associated items change vs replace the offending roller lifter.
Amsoil 10w-30 is my next change. Never had a temperamental engine and have gotten 350k - 500k from all I have owned on store bought synthetics. Now planning better and keeping 2 Amsoil changes on the shelf. Looking forward to my first UOA on the liquid gold.
Hydraulic lifter in the Chrysler 3.6 gas engine has the same problem. I had a Jeep wrangler with that engine, had to change all the lifters and a camshaft due to a couple failing. I've got a 2011 Ram 3500 with the 6.7, this I will not be upgrading.
If you were to be in the engine for one reason or another, are the school bus flat tappet cam and lifters a direct fit replacement into the pickup truck blocks? I have a long time before my warranty runs out, but it might be good knowledge for the future.
Hello Alex. I'm asking a big question to you. Would you be willing to make a review video of Fords 6.2 gas v8? The reason why I'm asking is because my long time childhood friend owns 3 superdutys with the 6.2 and a gen 1 Raptor with the 6.2. All 3 superdutys have over 250,000 miles with no issues and are the hardest working trucks on his farm property. I've been wanting to see a deep dive review of the 6.2 and I trust you're words and thoughts. Thanks 😃 greetings from Pennsylvania
I had a 2022 ram 2500 that developed a lifter knock at about 27,000 miles. I actually think the reason it started knocking is because it was constantly going through DPF regens and was getting too much fuel dilution in the oil. The excessive fuel dilution compromised the oil and its ability to properly lubricate the valve train. I think Ram needs to redesign their regen strategy and use a 7th fuel injector downstream of the engine block rather than injecting fuel on the exhaust stroke of the engine block. Might help improve valve train longevity.
I have the 2022 high output. Sad we are going to deal with this. I started the truck doing oil at 6000 mile service. I have dropped the interval down from that to 5000 and less. Hope I'm buying time for aftermarket to have a solution. This is sad buying a truck for almost 100 g and the heart is bad. I never got rid of my 5.9 and it is still making money.
I believe with the current emissions on the 6.7 and the engine having to regenerate all soot etc that the oil becomes contaminated very rapidly. I personally change not only my 6.7 and 5.9 Cummins oil at 5000 miles all of my gas engines receive the same service interval. It cheap insurance in my eyes . And in 35 years of driving I have never had an engine failure.😊
Why don't you change the oil on the gassers at 2,000? They are running on less than half the amount of oil than the diesels, the oil gets hotter and can contaminate more quickly. My opinion, which is only valid for me, is that if the oil performs perfectly for 10,000 then changing at 5,000 is throwing money away and wasting time.
@@GettysGarage Well, if the regen cycles work by injecting fuel on the exhaust stroke (like you've explained before), you should get more fuel contamination of the oil over time. Fuel contamination of the oil is one of the biggest contributors to excessive component wear. At least according to Lake Speed Jr. aka "The Motor Oil Geek". That and soot. Nasty business all of that. Wonder if you've heard of Speed of Air pistons. If you haven't you should definitely research those! Amazing stuff that greatly mitigates all of the harmful effects of the after gas acronym soup.
I'm a firm believer in "shorter" intervals on most engines, gas or diesel. The longer intervals on many modern diesel applications are just a recipe for failure in the long run. Oil does get contaminated no matter what, especially in diesel applications, and the more contaminated it is, the more wear is introduced to all of the components. I'd rather spend twice as much or more on oil changes than a fortune in repairs due to various failures.
Is there a benefit to running synthetic over standard 10w-30 in the warner months? Why do they switch from standard oil to synthetic from summer to winter? I know why for winter, the waxes and paraffins in the oil. But why not stick with synthetic year round?
20000 miles on my 2023 Ram 3500 HO and it already has a failed cam / lifter. It's been dealer serviced and has spent 40% of my ownership at the dealership 😢
Seems to be a ton of war on 10/30 vs 5/40 on these with no real regard to climate. I have a 21 with 29k she just started making the slightest slightest tick out front and I’m not real sure what it is just yet. I’d be curious if Gettys take on proper weight for these. I have been running mobile delvac extreme 10/30 and changed between amsoil and mopar and fleet guard syn version filters. I just ordered ADV HP 10/30 HD to see if that changes any noise. I almost grabbed 5/40 but I’m not sold that’s the answer. Being an amsoil dealer and shop I almost went that route but I wanted something a tick more extreme which to me was HP see if it changes the sound. That said I’m not sure it is in fact lifter or rod. Which makes me wonder how much of this is “lifter issue” vs the Cummins just developing Cummins noises and causing panic and being mis diagnosed. Especially first time diesel owners. But one thing we know is that fourth gen and down were so clacky you couldn’t hear a tick like that if you wanted. These new motors are so quiet (especially intact) you hear everything.
Great video, I’m super concerned as I’m hesitant to drop the huge dollars on one of these trucks. We are retired and do lots of towing miles with our 2004 5.9 Cummins dodge ( 200.000 km ) love the truck but as you get older the noise the truck makes when hauling is bothering our hearing. Plus in 2004 the truck has less power no Bluetooth,poor stereo less overall creature comforts but…… has great fuel economy and never breaks down. Oh and it’s paid for. See my dilemma? I would like if you were to dig deeper into the lifter issue.
2019 6.7 HO lifter failure at 117,000 miles , head needed rebuilt, still using coolant internally, no one can figure it out . I’m $11,000 in and still can’t use this truck. Hamilton cam and lifter kit $3,000 , head work $3,000 , studs , wire ring , expensive gasket kit .
I took ill, bought a camper , sold it and now I'm selling my 2022 Dodge Ram with 25 hundred miles on it. I'm only selling my dually because everyone tells me it's not good to baby these trucks. I'm an older fellow and bought it to haul my truck camper. I paid up there for I bought it when there was a chip shortage. Hope I can get at least 79 thousand. It'a limited with Asian transmission. 4x4, long horn package, such a beautiful truck.
23 Ram 2500 with 12k. I notice this tick at the dealer after the first fuel filter service at 8k. It hasn't gone away yet. I don't understand how a fuel filter service causes this.
I maintain about 20 of these 19+ trucks. No lifter issues. Some of them have 130k miles on them. Don't let them idle, use 10w30, and change the oil every 5k miles.
Ouch. Just bought a 2022 HO w/11K mi. Doing Amsoil 10w-30 every 5K mi and engine oil analysis to catch a roller lifter going bad. Are you going the flat tappet cam (Hamilton) route or just replacing the bad lifters?
The Getty Adventures, I have a 2020 Ram 2500 cummins, what would we be your recommended interval as a consumer of these vehicles that can prevent hydraulic lifter failures from happening would it be 6000-8500 miles as well do oil analysis to see if their any potential wear? I'm using 10w30 oil since I dont get temperature below 0 degree Fahrenheit.
I have owned a 2019 and now 2024 CGI Cummins. I run 10K oil change intervals, and oil analysis shows no abnormal wear, and TBN shows lots of life left in the oil. If I did more highway, I'd have no reservation of going 15K intervals. They should have stayed with the flat tappets, but, as you pointed out, requiring a lash adjustment was a marketing problem.I would add that an even bigger factor was soy-boys who wanted a silent diesel, evidenced by the scissor gear to take the rattle out of the timing gears. Perhaps the biggest factor of all is materials. Are they made of chinesium, like so much of Cummins stuff these days?
I think the difference between between the commercial cummins and the one in the ram could be packaging more so than fuel economy. Ram doesn't have to make it get a certain fuel economy like passenger vehicles. but they do have to make it fit into a the hood of a pickup. Probably had to change the oil delivery system and head for that.
I was at the dealership yesterday and they act like they didn't hear anything and it was OK but it's still under warranty so it's going back thanks for the video 👍🏽
I’ve got a 21’ 3500 HO with 93,000 miles. Just found out I’ve been running 15W-40… sBut no issues. I’m in FL. Should I go to 5w-40 or 10w30? I’m not sure I want the 30. But I want to switch to what’s recommended so I don’t have lifter issues.
RAM recomends oil change at 15k. Unless you use any biodiesel. Not sure about Canada, but most of the diesel stations in the USA are anywhere between 5%-15% RAM then recomends 12k interval. Where I live, we have Biomass diesel (not to confused with Biodissel) so I change oil every 5k.
I adjusted the valves on my 12 valve at 170000 miles and my 6.7 at about 150000 miles. Neither where out of spec, though some valves were on the edge. It wasn't very hard to do, not a big deal.
I adjusted mine at 65k miles. They were out of spec so if things get noisy it may need to be done sooner. Mine was also throwing misfire codes but seems to be fine now. It's definitely a lot quieter too.
That nub sticking out tracks in a groove in the lifter bore. A little wear there and the lifter wont track straight with the cam and it wipes the roller and lobe. So instead of just doing a quick valve adjustment you will do a cam swap!
Could you convert a 5th gen 6.7 to flat tappets relatively easy? You probably need a different camshaft, but if that's about it, then why not go for it?
We always change out our oil every 5,000 miles and we have never had any engine problems with any of our cars (1981 ram 250, 2015 Subaru outback, 2018 Toyota Tacoma, 2022 ram 3500) Doesn’t matter the make model or year regular oil changes keep your cars alive
Just got put in a new Volvo at work and they are now recommending 5w30 in their D13 engines doesn’t sound wright after years of 15w40 but I guess thin oil is the new normal Also if seems like they have started pulling the EGR after the DPF because it took almost 8000 miles before the oil turned as dark as my last trucks oil would in less than a 1,000 miles that may something all these engines need to have happen to reduce the amount of soot getting into the oil to help reduce wear
20k on my 2023 and lifter took out the camshaft. Fixed under warranty, but I bet it did damage to the other bearings that warranty didn’t care about. I’m selling the truck. Edit: 3k oil change intervals with minimal idling.
Odd they would blame and change the oil, I'm fairly certain Duramax and Powerstroke are both hydro lifters and T4 15-40 is the go-to oil on those... 50K+ on my 6.7 PSD with zero issues - -20*F starting every winter too.
I am guessing that the commercial engines stayed as they were for maintenance reasons. Commercial diesels are a competitive market, and no sense giving a client pause. RAM buys a lot of engines, so if that's the way they want it, that's how it goes. They own the warranty. Commercial folks don't want a warranty, they buy a lifetime reputation.
You might want to look into the fact that RAM trucks have a frequent regeneration issue that they cannot resolve. I have a 2022 Ram 3500 with a HO cummins engine. It gave its first check engine light at a little over 5000 miles.(code P2459 to frequent regen cycles). It has been doing a regen every 100 miles since that. This process is causing diesel fuel to get into the oil pan. Within just a few thousand miles after my last oil change I am already a quart over full on the dip stick. It has been tested and shows fuel in the oil. RAM has no answer for this other than to blame programming for the problem. But they do not know what the answer is and will not replace the engine control module or reprogram it. So you might test not only the hydraulic lifters but other engine components as to what the diesel fuel dilution is doing to that engine.
Very well could be, a good friend of mine had a 2021 3500 HO and his truck would regen almost daily. dealership threw the parts cannon at it but solved nothing - he ended up wisely trading it in. the Powerstroke and I believe the Duramax as well all use a "9th" fuel injector which directly dumps fuel into the DPF for regens. whereas the cummins dump extra fuel into the combustion chambers for regens. which 100% dilutes the oil with diesel but especially when the engine is running frequent regens. didn't really put the two together but reading your comment it would make some sense, once the oil is compromised it's only a matter of time.
@@jamiel9902 At least not in my case, as we do not give it excessive idle time. We might give it up to 10 minutes during the winter to heat up, but there is nothing excessive on the idle hours.
The 2024 Ram trucks are calling for a 15,000 mile oil change interval. I'd never run that long on a diesel. 5 to 7 thousand mile oil changes with the right oil weight is the way to go.
320,000 miles on my 2019 Cummins with no issues, but I've been running 10w-30 AMS Oil in my truck since day one, and I tow heavy every day. I also change my oil every 10,000 miles..
Awesome you're doing great. But I would switch to the 0w40 Diesel and go 7,000 miles max. It turns out that most oil analysis isn't telling the truth. I've had the same RAM truck for 23 years & never had anything go wrong minus a stuck auto lock and blown speakers. You can still make it to 4 or 500,000. But we like going forever. Oil still breaks down. And it's because of contamination. I'd rather run 0w40T6 and change every 3500 miles. Either way God speed, Baruk Hashem. 🇮🇱✝️🇮🇱

The HLA’s were specifically requested for the FCA engines by Ram in order to reduce NVH. Cummins obliged. But their commercial B6.7 is, as you already mentioned, still the traditional Flat Tappet. That should tell you everything you need to know. The wrong weight of oil (15w40) is definitely attributable to some of the premature lifter failures, but not all of them. There are deeper issues with the HLA’s in the 2019+ trucks and it’s a combination of supplier quality control failures and also design issues. Ram needs to scrap the HLA design and go back to the tried and true flat Tappet.
Well shame on Cummins for obliging to that request. I'm shocked at how many corporations operate with a scarcity complex. It's not like FCA would have dropped them over this. Cummins is what makes Ram HD trucks so enticing. If FCA were stupid enough to drop Cummins over this GM or Chevy would have been tempted to pick them up or it would open the door for a Japanese manufacturer to develope a HD truck.
Same with the CP4 debacle.

Why does it break the brains of so many truck guys when it comes to oil viscosity? The first number doesn't mean you're running a 5-weight. It means it's thinner when the engine is cold but it's still behaves like a 40-weight oil when the engine is up to operating temperature. It's actually more protective than say a 15W40 when temps are very cold. The oil flows faster, gets to the top end faster, and protects a cold engine sooner than the "heavier" oil and as it reaches operating temperature, a 5W40 behaves like a 40 weight just like the 15W40 behaves like a 40-weight at that temperature.
You are correct my guy. They just rip you off when you buy it. Only difference there is
People do not understand how a lubrication system works on an engine, oil pumps have a pressure relieve valve, and the gap between a Connecting rod journal / main journal and camshaft against their respective bearings is only 1.5 to 2 Thousands of an inch ( average human hair 1 Thousand of an inch ) So if you start an engine on a cold day with a 15W-40 oil, the pressure of the oil will open the relieve valve and dump the oil back to the oil pan and very little oil will make it to the top of the engine, your oil light or gauge will show pressure because most of the oil sending switches are screw next to the oil filters and not the top of the engine. That is the reason why the industry invented the multigrade oils best protection for areas with hot summers and cold winters 0W- 40 or 5W-40
I use Schaeffer's Full Syn 5W-40. I hope that it is a good choice of oil for my Ram 3500 with the 6.7 Cummins.
Its all just marketing to keep prices up. They could have just one oil on the shelf like 0W 40 and it would cover everything.
Great video and great detailed explanation of the changes that have been made to the Cummins engines. It is disappointing to see Cummins has changed the valve train for the Ram trucks vs. the commercial engines. Cummins was great originally because the kept it simple and now they have made changes that have hurt their reliability.
15k service interval? you got to be kidding me. clean oil= long life every time.
Cummins Ram has had that 15,000 mile OCI interval since the 6.7 came out in 2007. I can’t remember what it was on the 5.9 common rail, but might have been 10,000miles.

I think the main reason they went to hydraulic roller lifters is noise, efficiency, and emissions.
I wouldn't disagree with that.
Except emissions gains are negated by reliability decreases, because cars themselves have a carbon footprint. The oil burned to mine their materials, the oil burned by employees driving to work to make them, the oil burned by consumers driving to work every day to save up money to buy them. Etc etc. If the EPA can't see that, they need to go bye bye.
Appreciate all your videos!
Thank you sir
Hi Getty. Since you have access to the regular tappets and to the updated roller engines, it would be insightful to measure the valve spring rates for each. I assume that in order for the engines using the rollers to hit their power/torque/rpm/epa numbers, they have to use way higher spring rates to keep the valves from floating too much. That plus the oil sludge issue would cause the cams to wear alot faster.
Really appreciate you sharing findings and getting information out to the community!
As the owner of an 18 3500 with the 6.7L, I am interested in design changes like this (and the CP4) as the 6.7 Platform gets revised. I bought my cummins for the reliability - I dont mind wrenching, as long as my truck doesnt let me down...so I'm hanging onto my 4th gen!

Hi, just got my 2022 HO 3500 out of the dealership for P2459 code. Believe it or not (sit down for this), the problem was....wait for it.....the engine air filter. Yep, mine had 2 glue strips on the bottom of the filter that created too much of a seal and the engine was basically 'running rich' causeing excessive regen cycles, and also messed up the MAF. Both replaced, and viola, no more issues!
The old air filter was a Wix (great filter), but again, make sure (foot stomp) that there are no glue strips on the bottom.
106,000 Miles on my 2021, 2500, 6.7 Cummins. Bought it with 100k miles. Almost certain I have a lifter failure. I have the iconic driver side faint tick that I have seen indicates this failure (was not aware of that issue before my purchase, however I did notice that tick before purchasing). Getting it into the shop in a few weeks. After doing some research seems like OEM replacement is the best bet. After market kits for roller replacement require, lifters, push rods, springs, rocker arms, for the small price of $4,700. OEM is much cheaper. Flat tappet requires super stringent break in of running the truck at 2500 RPM for 30 minutes, and adding zinc additives to your oil, forever. For an engine not designed for that additive not sure if there are other part failure consequences when that is done. In my research I've also seen people talk about the keying on the lifter being a very low profile, potentially causing axial play causing the lifter to not be true perpendicular to the cam, thus not having a perfect role. The oil consistency, and oil change intervals may likely play in this failure as well. Sucks having a picky truck, and doing a cam job is ridiculous if you don't have a lift to push the whole body off of the frame. Will update with what the shop discovers and how much I'm in for.
I would 100% go with a hamilton flat tappet kit if i had lifter issues and was going to get a replacement.

They have needle bearing in lifters and ram Cummins does not have
But in this case the roller isn't failing. It's the part on top of the roller :)

In Australia you can’t get the oil RAM specifies but yet Cummins workshops use a different grade of oil compared to the dealers.

I change my oil every 12,000 kms on my 2021 Ram 2500. More often than called for but I’ve always done this (this is my 3rd 2500 with a Cummins). I’m at 155,000kms and have extended warranty to 160,000. Went for my oil change last week and apparently I have a camshaft/lifter issue. 🫤 at least dealer has been great, it’s under warranty but this video made me realize it’s likely a bigger issue especially the 2021 model year.
I listened to JB reviews he interviewed a Cummins mechanic with 30 years plus in the game, the guy had a good point and he said that all these problems started occurring when manufacturers started putting this lighter weight oil and making it required to run lighter weight oil in these diesel engines and if you look back over time, there was basic maintenance obviously with any motor in the world, but The Cummins motor didn’t have the issues that it currently has today and the only thing that’s really changed. Is the lighter weight oil?
5w40 isn't any lighter than a 15w40 at operating temperatures. But a 5W40 flows way better when the engine is cold and gets oil to the valvetrain much more quickly than 15w40. When the oil is cold, it takes a lot longer to pump hydraulic lifters up with a 15w than a 5w. Until they are pumped up, those lifters are hammering the roller against the cam lobes.
Lots of folks were running 5W40 year-round prior to the change to hydraulic rollers.
I’ve run 5w40 year round in all of my Cummins trucks going back to the 2000 5.9. I considered a newer one than my 2017 at one time, but too many issues popping up on UA-cam & forums. I’ll be sticking with the ‘17 for quite awhile & likely replace it with a gas truck if I have to at some point.
Jb reviews is an absolute cancer to the pickup world
I don’t understand like how google says as oil heats up it looses viscosity (agree) also every engine I’ve had looses oil pressure as it warms up. My question is then how does a 5x40w (thinner oil) hold up as well than a (thicker wieght oil) when hot and have comparable viscosity than the thinner (5)w x 40w?
Alex, you are not some guy on the internet talking.... I like to think you know your stuff. Oil change intervals at 15k is too long imo. Wish the company would go back to the old style lifter you showed us. Sometimes the KISS principle actually makes since. Thanks for your videos, Greg from North Carolina.
You think they might have switched to hyd lifters to help reduce NVH?
I believe all of the engine components receive oil pressure at the same time during startup. A check valve ensures oil is held in the galleries, similar to the way that fuel is held in the rails. No?
6.7 PS has always recommended 10w-30 or 5w-40 syn. The advancement of engine and oil technology has made it possible to run lighter weights in heavier duty scenarios.

I have a Ram 2500 diesel. Just clocked over 60,000 miles has a horrible lifter tick. I’ve taken it to three different dealerships and only one of them said that they can hear the tick the other two said that they can’t hear it which just pisses me off because it’s very obvious lifter noise. It has gotten way worse since it first started. It is very bad at a cold start. But the tick is there even when the engine is warm. It’s also got compression coming out of the intake on first start up.
It'll be a just a matter of time before solid rollers are available, if they're not already out there for the Cummins.💯
So here is my thoughts. Tiller lifters in general are a failure point. We are seeing them fail in the Chevy gas engines with cylinder deactivation, we see it in the ram with the mds systems and now we are seeing it in the Cummins engine. U know the real reason I think they went to the roller lifter. The small amount of hp gains you get from using them. Just my opinion though but it would suggest that when it’s not in that bus engine. Can the roller lifters be reliable sure if you use high end oils and high efficiency filters but if that oil gets just a little gritty those lifters are going to start causing problems.
I have 1 million miles on my 5.9 Cummins i change the filter and add 2 quarts of ams oil every 10k. No issues
Time for an overhead!
My 2013 Cummins is at almost 300,000 Mi and I've done only regular maintenance. It has been amazingly reliable. Next truck I buy will be a 2018.
Detroit diesel used roller lifters in the 71 series engine beginning in the late 1930's. As I recall, they were trouble free regardless of the oil viscosity. These weren't hydraulic rollers, however. Maybe go to a non-hydraulic roller lifter?
The roller lifter is superior to the tapet. However the hydraulic lifter isn’t.
Most large diesels use cam follower lifters and id support that any day.

I have ran 10w30 T6 and 5w40 Valvoline prem blue. Best results have been with 5w40 and less than 10k oil changes. I knew to buy for CP3…but never thought to research a change in valve train. 75k on truck and runs great but the UOA…can’t unsee the excessive wear metals that are significantly higher than the pre-2019 engines.

Watching and listening for signs of roller lifter wear/impending failure. Will likely go for the Hamilton flat tappet cam and associated items change vs replace the offending roller lifter.
Amsoil 10w-30 is my next change. Never had a temperamental engine and have gotten 350k - 500k from all I have owned on store bought synthetics. Now planning better and keeping 2 Amsoil changes on the shelf. Looking forward to my first UOA on the liquid gold.

Hello Alex. I'm asking a big question to you. Would you be willing to make a review video of Fords 6.2 gas v8? The reason why I'm asking is because my long time childhood friend owns 3 superdutys with the 6.2 and a gen 1 Raptor with the 6.2. All 3 superdutys have over 250,000 miles with no issues and are the hardest working trucks on his farm property. I've been wanting to see a deep dive review of the 6.2 and I trust you're words and thoughts. Thanks 😃 greetings from Pennsylvania
I had a 2022 ram 2500 that developed a lifter knock at about 27,000 miles. I actually think the reason it started knocking is because it was constantly going through DPF regens and was getting too much fuel dilution in the oil. The excessive fuel dilution compromised the oil and its ability to properly lubricate the valve train. I think Ram needs to redesign their regen strategy and use a 7th fuel injector downstream of the engine block rather than injecting fuel on the exhaust stroke of the engine block. Might help improve valve train longevity.
My 2020 ran in regen 90% of the time, dealer say that's normal!! Yeah Right.
I have the 2022 high output. Sad we are going to deal with this. I started the truck doing oil at 6000 mile service. I have dropped the interval down from that to 5000 and less. Hope I'm buying time for aftermarket to have a solution. This is sad buying a truck for almost 100 g and the heart is bad. I never got rid of my 5.9 and it is still making money.
I did banks upgrade and seemed to help with Regen. Not eliminated but seems to do alot better than stock. Air intake horn and boost toobs.
Built for the haul, not for the mall. I only recall 1 Regen below 100k miles.
I believe with the current emissions on the 6.7 and the engine having to regenerate all soot etc that the oil becomes contaminated very rapidly. I personally change not only my 6.7 and 5.9 Cummins oil at 5000 miles all of my gas engines receive the same service interval. It cheap insurance in my eyes . And in 35 years of driving I have never had an engine failure.😊
I mean the regens have nothing to do with oil really but the EGR pushing all that soot through the engine certainly does. So I can't argue with that.
I ment to type regurgitate my bad
Why don't you change the oil on the gassers at 2,000? They are running on less than half the amount of oil than the diesels, the oil gets hotter and can contaminate more quickly. My opinion, which is only valid for me, is that if the oil performs perfectly for 10,000 then changing at 5,000 is throwing money away and wasting time.
@@GettysGarage Well, if the regen cycles work by injecting fuel on the exhaust stroke (like you've explained before), you should get more fuel contamination of the oil over time. Fuel contamination of the oil is one of the biggest contributors to excessive component wear. At least according to Lake Speed Jr. aka "The Motor Oil Geek". That and soot. Nasty business all of that. Wonder if you've heard of Speed of Air pistons. If you haven't you should definitely research those! Amazing stuff that greatly mitigates all of the harmful effects of the after gas acronym soup.
I'm a firm believer in "shorter" intervals on most engines, gas or diesel. The longer intervals on many modern diesel applications are just a recipe for failure in the long run. Oil does get contaminated no matter what, especially in diesel applications, and the more contaminated it is, the more wear is introduced to all of the components. I'd rather spend twice as much or more on oil changes than a fortune in repairs due to various failures.
Is there a benefit to running synthetic over standard 10w-30 in the warner months? Why do they switch from standard oil to synthetic from summer to winter? I know why for winter, the waxes and paraffins in the oil. But why not stick with synthetic year round?
20000 miles on my 2023 Ram 3500 HO and it already has a failed cam / lifter. It's been dealer serviced and has spent 40% of my ownership at the dealership 😢
Seems to be a ton of war on 10/30 vs 5/40 on these with no real regard to climate. I have a 21 with 29k she just started making the slightest slightest tick out front and I’m not real sure what it is just yet. I’d be curious if Gettys take on proper weight for these.
I have been running mobile delvac extreme 10/30 and changed between amsoil and mopar and fleet guard syn version filters. I just ordered ADV HP 10/30 HD to see if that changes any noise. I almost grabbed 5/40 but I’m not sold that’s the answer. Being an amsoil dealer and shop I almost went that route but I wanted something a tick more extreme which to me was HP see if it changes the sound.
That said I’m not sure it is in fact lifter or rod. Which makes me wonder how much of this is “lifter issue” vs the Cummins just developing Cummins noises and causing panic and being mis diagnosed. Especially first time diesel owners. But one thing we know is that fourth gen and down were so clacky you couldn’t hear a tick like that if you wanted. These new motors are so quiet (especially intact) you hear everything.
Yeah, that's true. My 2001 Ram with the 5.9 has so much combustion rattle that I can't pick out any mechanical noises at all.
Great video, I’m super concerned as I’m hesitant to drop the huge dollars on one of these trucks. We are retired and do lots of towing miles with our 2004 5.9 Cummins dodge ( 200.000 km ) love the truck but as you get older the noise the truck makes when hauling is bothering our hearing. Plus in 2004 the truck has less power no Bluetooth,poor stereo less overall creature comforts but…… has great fuel economy and never breaks down. Oh and it’s paid for. See my dilemma? I would like if you were to dig deeper into the lifter issue.
Just add the creature comfort you need.
I have
2019 6.7 HO lifter failure at 117,000 miles , head needed rebuilt, still using coolant internally, no one can figure it out .
I’m $11,000 in and still can’t use this truck.
Hamilton cam and lifter kit $3,000 , head work $3,000 , studs , wire ring , expensive gasket kit .
I took ill, bought a camper , sold it and now I'm selling my 2022 Dodge Ram with 25 hundred miles on it. I'm only selling my dually because everyone tells me it's not good to baby these trucks. I'm an older fellow and bought it to haul my truck camper. I paid up there for I bought it when there was a chip shortage. Hope I can get at least 79 thousand. It'a limited with Asian transmission. 4x4, long horn package, such a beautiful truck.
Is running your truck better or worse at high speeds and Rpms. Around 2500 rpm. Or keep the rpms lower? 2020 2500.
23 Ram 2500 with 12k. I notice this tick at the dealer after the first fuel filter service at 8k. It hasn't gone away yet. I don't understand how a fuel filter service causes this.
I maintain about 20 of these 19+ trucks. No lifter issues. Some of them have 130k miles on them. Don't let them idle, use 10w30, and change the oil every 5k miles.
2022 124k mine is in the shop for bad lifters right now. Getting that sorted is fun. 5-40 oil changes at 10k km since I’ve owned it
Mine is in the shop getting lifters redone and a new Transmission
Ouch. Just bought a 2022 HO w/11K mi. Doing Amsoil 10w-30 every 5K mi and engine oil analysis to catch a roller lifter going bad. Are you going the flat tappet cam (Hamilton) route or just replacing the bad lifters?
@ dealer is putting in a new short block under warranty
The Getty Adventures, I have a 2020 Ram 2500 cummins, what would we be your recommended interval as a consumer of these vehicles that can prevent hydraulic lifter failures from happening would it be 6000-8500 miles as well do oil analysis to see if their any potential wear? I'm using 10w30 oil since I dont get temperature below 0 degree Fahrenheit.
I have owned a 2019 and now 2024 CGI Cummins. I run 10K oil change intervals, and oil analysis shows no abnormal wear, and TBN shows lots of life left in the oil. If I did more highway, I'd have no reservation of going 15K intervals.
They should have stayed with the flat tappets, but, as you pointed out, requiring a lash adjustment was a marketing problem.I would add that an even bigger factor was soy-boys who wanted a silent diesel, evidenced by the scissor gear to take the rattle out of the timing gears.
Perhaps the biggest factor of all is materials. Are they made of chinesium, like so much of Cummins stuff these days?
I think the difference between between the commercial cummins and the one in the ram could be packaging more so than fuel economy. Ram doesn't have to make it get a certain fuel economy like passenger vehicles. but they do have to make it fit into a the hood of a pickup. Probably had to change the oil delivery system and head for that.
I was at the dealership yesterday and they act like they didn't hear anything and it was OK but it's still under warranty so it's going back thanks for the video 👍🏽
Cat has been recommending 10w30 for 30 years now with no issues so I would have no issues running the thinner oil…
08 Ram 335k miles , never have done a valve adjustment
I bought one with 350k on it after doing the valve adjustment it was quieter and better field economy.
Thanks Alex. Give me flat tappets any day. Any other issues with them?
I’ve got a 21’ 3500 HO with 93,000 miles. Just found out I’ve been running 15W-40… sBut no issues. I’m in FL. Should I go to 5w-40 or 10w30? I’m not sure I want the 30. But I want to switch to what’s recommended so I don’t have lifter issues.
woah woah woah... flat tappets dont work with modern oils, like they explode. how does this engine get around this????
2019 ram 3500 6.7 cummins. Running Amsoil 6x 15w-40 and change every 5k-7k and no issues yet at 94k miles
Schaeffer 5W-40 changed every 5,000 miles. I love my truck too much to worry about the extra cost of an oil change.
So sounds like if we use the correct grade of oil we’re fine?
RAM recomends oil change at 15k. Unless you use any biodiesel. Not sure about Canada, but most of the diesel stations in the USA are anywhere between 5%-15% RAM then recomends 12k interval. Where I live, we have Biomass diesel (not to confused with Biodissel) so I change oil every 5k.
Ok so any 10-30 oil will work? Like a Mobil 1 10-30 full synthetic?
No. Needs to have CK4 approval.
@ bingo that’s what I needed thank you
Wonder what the mpg changed to with thinner oil and rollers?
great video thanks for the info !!
Im running Schaeffer 5W-40. Is there anything wrong with that and Hydraulic Lifter? Full Synthenic.
I adjusted the valves on my 12 valve at 170000 miles and my 6.7 at about 150000 miles. Neither where out of spec, though some valves were on the edge. It wasn't very hard to do, not a big deal.
I adjusted mine at 65k miles. They were out of spec so if things get noisy it may need to be done sooner. Mine was also throwing misfire codes but seems to be fine now. It's definitely a lot quieter too.
That nub sticking out tracks in a groove in the lifter bore. A little wear there and the lifter wont track straight with the cam and it wipes the roller and lobe. So instead of just doing a quick valve adjustment you will do a cam swap!
No replacement for clean oil ! Especially when the exhaust is pumped back thru your engine
Great, i dumped my chevy 18 months ago because it was showing signs of lifter failure, now this, and I swore i heard it a few days ago 😞
Hi, on 2011 tru 2014 ceramic bearing in the turbo what is percetage of failure to the turbo?
Could you convert a 5th gen 6.7 to flat tappets relatively easy? You probably need a different camshaft, but if that's about it, then why not go for it?
Warranty.
We always change out our oil every 5,000 miles and we have never had any engine problems with any of our cars (1981 ram 250, 2015 Subaru outback, 2018 Toyota Tacoma, 2022 ram 3500)
Doesn’t matter the make model or year regular oil changes keep your cars alive
Just got put in a new Volvo at work and they are now recommending 5w30 in their D13 engines doesn’t sound wright after years of 15w40 but I guess thin oil is the new normal
Also if seems like they have started pulling the EGR after the DPF because it took almost 8000 miles before the oil turned as dark as my last trucks oil would in less than a 1,000 miles that may something all these engines need to have happen to reduce the amount of soot getting into the oil to help reduce wear
My2019 HO 3500 manual states it can run Cummins CES 20081 which is the number on Shell 15w-40 T6 full synth.
20k on my 2023 and lifter took out the camshaft. Fixed under warranty, but I bet it did damage to the other bearings that warranty didn’t care about. I’m selling the truck. Edit: 3k oil change intervals with minimal idling.
Odd they would blame and change the oil, I'm fairly certain Duramax and Powerstroke are both hydro lifters and T4 15-40 is the go-to oil on those... 50K+ on my 6.7 PSD with zero issues - -20*F starting every winter too.
You're really playing Russian roulette using that oil. I would never use conventional 15w in any truck that I'm towing with
I am guessing that the commercial engines stayed as they were for maintenance reasons. Commercial diesels are a competitive market, and no sense giving a client pause. RAM buys a lot of engines, so if that's the way they want it, that's how it goes. They own the warranty. Commercial folks don't want a warranty, they buy a lifetime reputation.
@@stevegillmeister7738 cummins has a virtual 100% monopoly now
You might want to look into the fact that RAM trucks have a frequent regeneration issue that they cannot resolve. I have a 2022 Ram 3500 with a HO cummins engine. It gave its first check engine light at a little over 5000 miles.(code P2459 to frequent regen cycles). It has been doing a regen every 100 miles since that. This process is causing diesel fuel to get into the oil pan. Within just a few thousand miles after my last oil change I am already a quart over full on the dip stick. It has been tested and shows fuel in the oil. RAM has no answer for this other than to blame programming for the problem. But they do not know what the answer is and will not replace the engine control module or reprogram it. So you might test not only the hydraulic lifters but other engine components as to what the diesel fuel dilution is doing to that engine.
Very well could be, a good friend of mine had a 2021 3500 HO and his truck would regen almost daily. dealership threw the parts cannon at it but solved nothing - he ended up wisely trading it in. the Powerstroke and I believe the Duramax as well all use a "9th" fuel injector which directly dumps fuel into the DPF for regens. whereas the cummins dump extra fuel into the combustion chambers for regens. which 100% dilutes the oil with diesel but especially when the engine is running frequent regens. didn't really put the two together but reading your comment it would make some sense, once the oil is compromised it's only a matter of time.
Didn't the 6.4 Powerstroke use the same strategy?
Worked well for them also
I wonder if some of this is due to excessive idle time. Idle diesel = bad = lots of regens.
Frequent regen is due to not allowing to complete regen in the first time it started
@@jamiel9902 At least not in my case, as we do not give it excessive idle time. We might give it up to 10 minutes during the winter to heat up, but there is nothing excessive on the idle hours.
My late 2023 did not even make it to the first oil change. Lost a lifter. Still sitting at dodge. POJ.
The 2024 Ram trucks are calling for a 15,000 mile oil change interval. I'd never run that long on a diesel. 5 to 7 thousand mile oil changes with the right oil weight is the way to go.
Roller cam is not compatible with flat tappet cam and vise versa.
I've got a 18 ram Cummins. At what miles should I have my old style lifters adjusted? I've got an 05 with 113k also.
I would bet that the soot from EGR is contaminating the engine oil and causing the lifter to malfunction .
Glad I've got a 4th gen at this point.
