Have been thinking more and more about the lifters on my 2019 6.2L with about 95k on it. No symptoms so far, but just weighing options in terms of keeping the truck, trading it, possibly doing a preemptive service, etc. At this point my feeling is that the odds are good enough that with some good monitoring I should be able to get comfortable that I could get some warning of a problem before it gets too far along.

 

How likely is it that I'd see signs in idle misfire counts (pulling from an OBD tool, not just looking for a CEL) before a lifter totally fails?

 

And with the failure modes I see with people doing the repair (the rollers and cam lobes eating each other) it seems like there would be an early signal in oil analysis with increased metals. Unfortunately I just changed my oil and didn't think to grab a sample, but am I right to think that if I start sampling there's a good chance I'd see early signs of a problem before it gets catastrophic?

 

Anything else to keep an eye on?

How often have you changed the oil? A key factor I think for this issue.

My sister in law drives a 2019 Escalade. Short distance. She wouldn’t let her husband touch it. She takes it to the dealer when it tells her to. She has 75K miles on it. She definitely has a snobby attitude claiming if you have a caddy you don’t work on it yourself. My brother is definitely capable. When the 6.2 failure started. 2019 is supposed to be ok.

Every 5k typically. Longest it ever went (one time) was 6,200. Average interval over the life of the truck is 4,950. Always full synthetic, quality filters, etc.

I've definitely seen a few reports of 2019s failing, but I do think it's probably less common. Part of why I'm leaning toward just continuing to roll the dice. But I'd like to have some way to keep eyes on it to get some advance warning if something is starting to go.

 

Seems hard to believe that something like that lifter on the right in the attached picture (and the matching cam lobe wear) wouldn't show up in an oil analysis before completely failing, but I'm just a little surprised with all the chatter on the subject, I don't see anyone talking about it. Same with watching the misfire counts.

Great!

 

Yeah, I've babied this thing since day one, planning to keep it for the long haul. Changed the diffs and transfer case fluids at 4300 miles (dealer parts guy looked at me like I was insane when I went in to get fluid) and again since then, did the trans fluid and filter, etc, etc. I'm pretty invested in it (time more than money, really) so hoping to stick with that plan.

I have almost 84K on my 2019.  I do oil analysis (2x a year) and the only "issue" i ever see is higher fuel dilation in the winter months.  Im going to stick with my 3K mile oil changes as I plan to keep this truck for some time.

Keeping up with maintenance even if the engine goes it’s cheaper to replace it versus getting a new one. My wife with her 2011 Genesis even though it’s a cream puff it’s probably worth about 6-8K. She’s made it pretty clear the engine will be replaced if it goes. For about 8 years it rattles like crazy when it starts for about 2 seconds, 5 if it’s cold. They have a problem with the timing chain tensioner bled off overnight. I go out with her everyday when she starts it up to make sure it doesn’t blow up.

I change fluids more than most do, it has served me well over 50 years.

Yeah, agree - my main thing is, if a lifter is on its way out, I'd like to catch it before it totally fails and blows the engine full of metal chunks and who knows what else. In that case, I don't even think replacing the engine would be my answer. I'd just park it and take my time opening it up and replace the lifters and cam and maybe do a DoD delete at the same time (although I'm not nearly as big a hater of DoD as many are, I'd probably turn into one once it led to me having to rip my engine apart). So at that point the cost (at least dollar cost) wouldn't even be that great.

 

At least as importantly, I'd prefer to know ahead of time so I don't end up stranded on the side of a snowy road with my son and his friends going skiing when it's -15 out and we're 3 hours from home and we all have work/school the next day.

 

Really curious if any one has reported a failure that was picked out early by oil analysis or misfires or any other symptom. Seems almost obvious to me that it would be detectable, but again, also just seems weird that no one is talking about it as a way to help manage this risk.

Do the dod delete, problem solved.

I just feel like that's the same work I'd be doing if a lifter goes (or potentially more even), but instead of having a 1% chance or a 5% chance or whatever the chance actually is, by deciding to do it, I'd be voluntarily choosing a 100% chance of doing the work.

 

I know a lot of times a lifter going leads to an engine replacement, but I think a lot of that has to do with dealer shop labor rates and expertise changing the economics to where that's just what makes sense. And if it was under warranty, I'd kick and scream until I got a new engine out of it. But for me out of warranty, I'd most likely park it and take my time tearing it down and fixing it.

 

Plus, I might be the only one here, but I actually appreciate the fuel savings of DoD. I'm amazed when I can get like 20MPG going 85 on the highway in 6000lb vehicle with all the aerodynamics of a barn. So if it's not actually causing a problem for me, I wouldn't mind keeping it, particularly if there's a way to get some advance notice if a problem is developing (at which point I might just do the delete to be done with it while I'm in there).

It can be more work/expense if the lifter goes, because it doesn't just wipe out the cam, but also can result in crankshaft damage by sending metal debris to it.

 

But it's a risk vs rewward thing, as even doing the delete up front isn't risk-free, as some debris can get into the wrong spot while doing it, or you get a bad part...

Yeah, part of me wishes I'd just traded it for a 2500 last summer. According to KBB mine has dropped 25% in value since then. Oh well, too late now. Let's gamble!

    • I have never seen GM instructions for the other trucks as per the HD with the 6 speed or the half tons but had got the impression that the HD trucks with the 6 speed were not having the same problem that the 10 speed and pan presented. Also video that I have seen of the HD 10 speed with the gas engine starting in 2024 model year showed that it was a real struggle to even make it work when pulling down hard on the exhaust after undoing the exhaust hanger bracket on the side of the transmission as after all there is little room for the pipe to even go down behind the Y joint as it soon would hit a frame cross member. Also that they had tried just like I did with the gasket off and no way was that pan coming out any way they tried to manipulate the pan. From that as well as the local transmission shop talking about the pain in the rear issue, I was not expecting my pan to come out because GM shows it was not even intended to come out without dealing with the exhaust piping.    It would be nice to claim, here's what you do and its easy to remove the pan guaranteed on any HD truck with the gas 10 speed but dollars to donuts the next guy trying what I did would not have the same luck as the exhaust was just manufactured slightly different and be pissed off at my claim that the pan comes out with no issue. Its more of a try and see if your particular truck might work like mine did .... or not !. 
    • Sorry I didn't see this until now, but it works on both the 6 speed and 10 speeds, as well as all the half tons too.
    • Hello, I have a 2018 GMC Sierra 1500 that I recently changed both motor mounts on due to the driver's side being blown out. After replacement I seem to have a steady vibration that I can feel in the pedals and the back of the seat. At this point I'm convinced that the aftermarket "Anchor" branded mounts I used are not performing as well as OE, the only real reason I ended up using the mounts in question was because my local dealers were out a few months to get a Driver's side mount. I've tried "Neutralizing" the mounts according to the motor mount TSB published for these truck to no avail. My trans mount is also in great shape and seems to be absorbing vibrations swimmingly. As far as I can tell there is no issues idling, my idle RPM is steady and I've recently put GM plugs and wires on, however, I have not cleaned the throttle body or intake valves. Any one else have a similar experience with aftermarket mounts? Patience certainly is a virtue that I wish I exercised here. Thank you!
    • I still saw people out for runs, on their bikes/motorcylces, jeeps with the doors off driving around here the past 2 days. I guess we are just used to it here haha.   Tasted like a bonfire the last 2 days.
    • The TCM has to be flashed before it can drive.   If you installed it the way it is, it has the OS (operating system/program) from the 2010 truck you got it from. That will not match with the VIN/OS pair that your 2013 truck has.   You can do the full install. Then tow it to a dealership and they can flash the trucks PCM/TCM with the latest program for your VIN.
