Lifter Failure? Report it here!

Did you by chance run it with cover off and mark the rods to see if they were rotating?

I did run it with cover off. From the looks of the pushrod tips I would say there was no rotation on a couple. I did not put marks on any. Great idea. Next time I’m in there I will.

No rotation normally = bent.. even in the slightest. But that's with flat tappet/ground cam... These rotate but (my understanding is) it is way way less rotational force. Basically only due to off-axis rod to lifter/rocker cups. Correct me here but I think the rocker cups rotate, right? If so I'd think more polishing up top would be expected.
 
I don’t think they do. I believe the cups are pressed in. Not positive. I agree they must rotate somehow because some of them had good polishing. If you look at some of the older pics I put up, there were a few that had directional grooves in them. I need to just do the conversion and be done with it.
 
Well, it’s my turn to be added to the list.

2022 SO, 66k miles on the clock. 1840 hours, with 356 at idle. Have been running Amsoil Signature Series 5w40 with Donaldson filters. Truck was whisper quiet yesterday, and started sounding like **** this morning when I started it up to get warm before I changed the oil. Truck sits in a garage 90% of its life, and has had no regen issues.

I have only got about 5k miles on this particular oil change, but I’m sitting at about 13 months, so I figured an annual was a good call. Probably gonna leave that oil in it now for the dealer to do an analysis on.

Bought the truck with 55k on it from Washington state, so service history is unknown.

Did the noise go away after the oil got through the engine?

I should have clarified;

I didn’t end up changing the oil, for fear of the dealer claiming that the oil change spurred the noise.

I’m still wildly under the miles/hours interval for my oil change, so I figured another 50 miles and few days before the dealer sees it will not hurt.
 
I ask because I notice if my truck sits for awhile the engine gets pretty dry, inevitably causing a rough startup. At least till the oil get in the lifters
 
I had my 6.4 hemi replaced for failing lifters. I wonder which engine has a worse ratio of produced/failed lifters between the hd gas and deisel.
Also wish I knew new that ratio between ram, Ford and chevy. They all seem to have an issue with this or cam phasers.
I like the flat tappet idea. And really like shim on bucket DOHC engines, without variable valve timing..

What year truck, and at what miles?

If I had to guess, and it is JUST a guess, I'd say more problems with diesel than the 6.4. And also guess that RAM has more lifter issues than Ford and GM combined. But as we all know, each manufacturer has it's own set of engine issues.

Chevy 1500s were doing pretty bad. The LS engine with cylinder shutdown killed their brands reliability. 05' era were bullit proof.
My 6.4 is a 2022. Lifter failed and started to grind the cam. It was replaced at 32k miles. Have 42k now.
Also there are soo many cars with these lifters in 392 srt8 from 2019+ and hd trucks, i don't see that many being replaced. Longevity is a question mark still.
Fresh oil seems to be key.

Thats another good reason to use 5w40 year-round. "Thinner" oil will pump to the lifters faster at startup. But even if it doesn't, in my head it does, and thats all that really matters. LOL
 
Yeah im at like 93k now on the clock. That oil analysis was hotshot pao 5w-40. Im a little concerned with the aluminum. But I guess time will tell.

I feel the same way. Just put 10w30 in, man it runs so much quieter. Hotshots tends to run a little thinner in my opinion. Probably from the fr3. 5w-40 hotshot compared to a valvoline blue 5w-40. It seems like the hotshot flows faster, at least out the bottle.
 
I forgot to mention I did studs on that oil change Some of that arp sauce might make some of the numbers different
 
Why is there so many videos and information out there about Duramax and PowerStrokes having this same noise? You'll find them with a quick search. Do they all have lifter failure issues too? Why do GM and Ford write off the noise as normal or related to recent oil changes? All coincidence, perhaps, perhaps not. This is truly a mystery.
 
Ram told me mine was normal quite a bit. I felt better about my truck after watching those videos of the dmax’s and ford videos. The noise eventually made me paranoid enough to crack the valve cover off. Had a couple pushrod ends wore down. Replaced with performance set. Still makes noise after oil change. Scoped the cam with a camera including lifters. Everything looks fine on that front.

This is part of my point here. This typewriter noise seems to be very prevalent across all three platforms. So, we have a correlation question here. It is quite possible that people have had lifter failure and the typewriter noise, but was that even correlated or was it coincidence? I just can't wrap my head around how this noise is so prevalent and diagnosed as so many different things. I've read injectors, DEF injector, timing belts, AC compressor and fresh engine oil to name a few. Ford apparently took a stand and issued a TSB that says it is normal.

Who can explain why this sound is so intermittent and erratic? I'm not a mechanic, I'm an operator and I only know how to break things. Shouldn't something that is mechanical like this spinning at whatever fast RPM continues get worse if it's an actual problem? Wouldn't it be more rhythmic in sound?
