Lifter Failure? Report it here!

Pretty much the same thing my dealer said to me, just going to run it till it knocks a lobe off the cam and grenades' the entire engine lol.

What a disaster lol, first time buying a new truck in 15+ years, of course I didn't realize they went away from flat tappets, wouldn't have even considered this truck had I known.
 
So yeah. I just read thru this entire thread, and like alot of you, now I'm kinda regretting my purchase. I thought I had done a damn good amount of research before purchasing this 2024 3500 HO just 6 weeks ago, and now I read all about possible lifter failures. I'm trying to put things in context though-- this is a forum thread dedicated to lifter failures, asking folks to post their issues, and theres only a handful of complaints in the grand scheme of things. One thing I noticed though is that hardly anyone who has posted of failures or noises has provided any supporting info, such as the year of the truck, SO or HO (if that even matters, which I doubt), miles on the engine, how the truck is used, etc. As I said, my new truck is a 2024 and its got just over 3k miles on it. Its all stock and will remain so for the duration of my ownership. I am meticulous about maintenance, probably overly so. Currently we tow an approximately 10k# BP toy hauler but plan to upgrade to a 35' 5th wheel at about 15k#, hence the purchase of the 3500. And now that I'm aware of the potential for lifter failure, I'm going to have the same stress and worry every time we drive it as I did with my old 2006.... every mile just waiting for something to let go. I bought the new truck to get rid of the stress and worry!!

So, in anyone's opinion (or based on some actual data), what percentage of these new trucks do you think are experiencing this failure? I can't imagine its an enormously widespread epidemic or surely I would have read about it somewhere before I purchased the truck. What would be a reasonable expectation? 1 in 2 trucks? 1 in 10? 1 in 100? Or, given enough miles, its an eventual certainty with 100% of em? I know, hard to say. But if someone DID say, I'd feel better. (or worse). LOL

If this lifter issue has been a known point of common failure by Ram and Cummins starting with the 2019 engines, and the failures are happening at any sort of alarming rate, its difficult for me to comprehend that after 5 years it still hasn't been addressed by Ram and Cummins. Kinda like the CP4 issue, once it became obvious that this was an epidemic-level point of failure, Ram/Cummins made the smart move to switch back to the trusty CP3. It makes obvious good sense for any manufacturer to make these changes as needed to avoid forever-lost brand confidence and to avoid what has to be astronomical costs in warranty repairs-- or worse, lawsuit settlements. Based on that logic, I'm going to assume that the lifter failures, while a real bummer for those who have had to deal with it, are not at any epidemic level. Or, unbeknownst to me, it has already been addressed by Ram/Cummins.

All the data points you asked about are in the spreadsheet in post #1. It’s just a small slice of folks who come to the forum, so not scientific but good information to have if you’ve run into any of the same issues. I’m sure there are others who have had the same problem, who have never been to the forum and input their data on the spreadsheet. I don’t believe it’s widespread, I’ve seen where there was a few different styles of lifters being used which to me says there was a correction attempt midstream. Unfortunately, like the Hemi owners, it’s just another thing to be aware of and be sure to keep up with your maintenance intervals. Check out the Cummins forum, there is a whole thread on roller lifters here:

Eh, it's a horrible design, I'd bet it's as widespread as the LS and HEMI lifter failure issues if not worse.

The amount of trucks showing this issue with less than 40-50K miles is pretty telling that this is going to be a big problem the longer these trucks are on the road, it's not like some trucks got bad lifters and some didn't, the lifter design is bad period.

I hope I'm wrong, but I seriously doubt it.

There are enough people with 300-400k miles with no noise on stock lifters. I dont think its a lifter issue to me it looks like the factory block machining some have issues some don’t. There have been people who used the rollers with no hydraulics and they have the same issue so the lifters are not tracking straight on the cam clearly.

Plenty of HEMI's and LS's with that much mileage without issues as well so not really proving anything there.

Might as well be saying the CP4 isn't that bad because there were trucks with 500K and a CP4, not really proving anything that SOME survived that long lol.

Everything that I have read about the block machining is limited to very early 2019 engines. The locating dowel in the lifter that can pretty much just fall out is the cause of the lifter not tracking properly on the cam. There are videos out there of those locating dowels just falling out of the lifter, they surely aren't keeping it straight lol.

Hemi and LS don't use the same lifters so cant compare them the slot the dowel rides in is pretty sloppy in some, one i saw had .005 slop which is far to much they should have max .001 the roller is the issue a flat hydraulic lifter is usually problem free.

Either way the current setup is not ideal and flat tappet was much better

Completely agree.

The real question is flat tappet conversion or trade it in on a 25 :D

Unless they have an engine design change, you’ll have the same setup in a ‘25, maybe an 8 speed transmission. Not sure what year truck you have but I think flat Tappet conversion would be the way to go. Would end up costing you less in the end. Down payment, financing, new vehicle depreciation etc…..

I have a 2022, I bought it used so I'm in a decent place with it. I agree though, 3K and a weekend in the shop certainly beats out buying a new truck.

Interesting, my truck goes back tomorrow for a transmission clunk that supposedly a quick relearn would fix it but of course it did not. I also mentioned the tick I hear in the 1500rpm range and they are going to look into it. I’ll see if they give me the same story.
Click to expand...
I've been reading this whole thread because my truck ('24 2500 has the same loud tick). I'm replying to your post because it also has the same loud clunking, but also a muffled screech or sliding metal sound when changing gears. It has 8000 miles on it. First oil change was at 4500 and an intermittent ticking sound showed up shortly afterwards. Dealer said it was the def. Ticking has become louder and constant so we took it to a different dealer on 9/11 this week. They went ahead and changed the oil again to see if it helped with the tick. They called and said tick was gone and transmission sound is normal so come pick up the truck. As soon as I started the truck the ticking was so loud that other patrons made comments about the bad lifter sound. Needless to say, the truck is still there. Dealer is opening up a STAR case with Chrysler. Let me know what they find out with yours.

Here is the result of the Star Case. Not to sure how to feel about this.
 
This is kind of the approach I am having right now. Although I am under a 125k warranty I will continue driving it until a failure happens.
 
has anyone looked at the cut in the lifter valley to keep lifter oriented to see if there is possibly some bad machining or left over casting material causing the lifters to get stuck?

2019+ LIFTER FAILURE:

I’ve had quite a lot of requests to document these.
If you have had a lifter failure, I’d like to record your trucks information. The goal here is to see how many of these failures have occurred, as well as document basic data surrounding the failure. You can open the form to view it prior to filling it out, that way you can see if there’s information you need to collect prior to filling it out and submitting it. I’ll be using this reporting form to gather data. I will transpose the information onto a publicly viewable spreadsheet as the forms get submitted. Any questions or feedback please comment below.

You can find the form at this link:
forms.gle

2019+ RAM HD 6.7 Cummins Lifter / Cam Failures Data Tracking: Reporting Form

The purpose of this form is to document and track the number of confirmed lifter failures experienced in 2019 and up Ram HD trucks with the 6.7 Cummins engine. Please submit your information. The results will be posted on a separate Google Sheets spreadsheet and posted for public viewing...

I am late to the game. But my ram just failed. The dealer is a rip off. They did not do any diag on the truck. Heard it and said I need a engine. They did not even do a oil sample and flat out told me they did not check anything. I towed it to a great diesel shop and they diag it within a couple hours. Cylinder 1 exhaust lifter failed. Will pull the cam and inspect for damage. If no damage will go to the solid tappet. 160k on engine. Thanks foe this form. I will fill it out when I get thw truck back

Make sure the block itself is checked for damage as well. Any damage to the machining where the lifter body keepers insert into the block can cause excessive axial play and you’ll be right back wi the issues. Probably a good time to consider doing the Hamilton flat tappet conversion and be done with it.

I was just gonna post this. There are MORE people with 200k+ miles on these rigs than those with lifter failures. FAR more.
