6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

Need a little advice here before I just trade the truck in for a 2500 6.6L L8T and SPA it.  Really dont want to be left with a broken truck and lose value.
 

Just replaced my oil lines due to leaking, never leaked more than half a quart between 5k oil changes (barely noticeable on dip stick).  Afterwards, hopefully just paranoia, I hear a distinct powertrain noise.  Could have always been there, but now paying more attention.  Pretty sure the leak wouldn't have caused some kind of oil delivery issue to some of the internals.

I really don't think its the direct injection system, as that is still pretty distinct.

Took the truck into the dealer, and specifically asked for someone who has worked on the L87 (6.2) lifter failure, and they stated if it was the lifters/cam failing or making that noise, I would have a CEL and misfires/performance decrease.  Which I do not.

At what percent or miliage do you change your oil?  You should be changing it at 5k miles, I don't care what anyone else says.  

 

Personally if I were you,  trade it before you have transmission problems.  

 

I have a 2020 6.2l 10l80 112k miles.  93k trans idler bearing gave out and started whining. At 112k transmission failed. Well, slight slip then fishbite but dealer said needed a transmission. So about 14k worth of trans work at the dealer.

5k always...maybe twice did it go ~100 miles past waiting for royal purple to be delivered.  I really doubt an oil quality issue.  Today, at a bar, a GMC mech, so who knows how valid; suggested switching to 5w40 (the lifter failure "fix") which is still in court.  I honestly just need, but probably wont get, it's not a lifter failure, as a response.  If trans failure on the 10 speed, going 6.6L, it would be the same problems.  For all of that, I'd go Ford Godzilla motor.

The oil is NOT a lifter failure switchover.  You are mixing up two separate things.  The 0w40 had to do with protecting engines built from 2021-2024 which is the 6.2 "recall" range and special coverage for engine machining and manufacturing defects with the crankshafts and connecting rods.

Sorry had to fix it for you, lower end 6.2 issues are still happening because the parts is still being made at the same Mexican sweatshop. Why should anyone expect anything other then failure when you have people being paid 5 bucks an hour to make crankshafts for your premium engine. The oil weight has beyond nothing to do with this issue, it has to do with paying near slave labor wages to make important engine components.

 

I think the Oil debate was just a stall tactic and a throw it against the wall change to see if the thicker oil helps prolong engine life to get out of warranty. I have watched tear downs of never run 6.2 engines and all the finish surfaces were trash but like i said you get what you pay for!

Well...went to drive to work this morning, and it kicked the bucket.  Its at the another dealer now; dont trust the previous one that just said "You do have powertrain noise.".  Hopefully just lifters and pushrods.  Fingers crossed they dont rape me, but I'm sure it will be 10k rebuild or 13k for crate.  Just sad this happened at only 56k miles.

Sorry to hear that bud. Any updates?   

 

Also have you thought about going to an independent shop, ordering a DOD deleted rebuilt engine and have the shop tune it?  I bet it would be cheaper and more durable than another DOD engine with the same trash lifters.  It's the lifter quality, not necessarily the design that is causing the issues.  There is a brand of lifter The Car Wizard recommends if you go back with the DOD.

Dealer called back, not just lifters, but the shavings in the oil pan, can pay them more diag to tear it down, but would cost another 3-5k.  So decided new motor, 13k comes with 3 more years of warranty.  So said screw it.  Got to get it fixed to be worth anything.  Can upsell the new motor a bit for the 43k quote from the dealer after repair.  Going to see how that goes.  Looking at the 2026 Chevy 2500 ZR2 6.6L gas, but really dont like the price tag.  Maybe something else will come out in the next year or two that will

I did think about going independent and having them pull the motor and rebuild without DOD (with some upgrades of course), came out to about 10k (Lifters, cam, pushrods, crank, etc).  Of course that assumes my block doesn't need machining.  It will cost me more if they tear it down and the block isn't good.  Same as dealer.

 

So in the mean time, I'm done with DOD and the 6.2L in the near future; all of the trucks (RAM, GM, Ford, Toyota) have issues because of it.  Going to buy this cheap, but good on gas, 2016 Miata tomorrow to get around town.  Tired of riding the bike in the rain just to get the milk.

 

WHO KNOWS, MAYBE GM WILL REIMBURSE ME BY 2035!  56k miles and a bad engine just doesnt make sense to me.  Even if I would have got the extended warranty, it would have ran out too.

Did your dealer just tell you there is nothing they can do? Usually with that low of miles they might be able to secure a partial amount to help off set the cost or something, perhaps call the gm service line. I know it's a long shot but heck even getting a grand in gm accessory's gifting would help with the sting of this.

 

I take it the 13k is a for a direct crate replacement engine? I wouldn't blame you because I'm sorry the independent shop route is a bumpy one imo. There are FAR more hack mechanics out there then good reliable ones imo, and finding a go fast shop that does good solid work is very very very hard to come by imo these days.

Unfamiliar noises can definitely cause concern, Chris.

Looks like a bit more going on here then unfamiliar noises..... His motor let go on him @ 57,000 miles and GM clearly thinks that is an acceptable outcome. How about actually doing something and work to help secure him at least partial coverage here?

What do you mean, like another middleman?  Really needed my truck this weekend to pull my trailer, but after almost a month, its still not done.  Service advisor is at least going to put me in a 2026 Colorado today that cant even pull my trailer.  I feel like putting someone else between the dealer and I would just delay things further.

What really needs to happen, GM needs to drop the suit, accept they messed up, and start paying for their mistake.  Or is it only acceptable for us (The taxpayer), to bail GM out.

Ended up having the buy a cheap, but reliable 2018 Maxima, and it feels like I'm going to grow a uterus.  Now all the sudden a vehicle is available.  So now I'm 18k for the car; 13k for the motor.  And who knows what else they will try to delay and add on.  This truck is going to be sold immediately, and GM will never see another dime from me.

      Trim level custom/pro

      Are you going to take long trips in it?  If so, try out the seats in the various trims. For me the lower trim level seats were not comfortable.

      I have a 2016 that I bought new and still own. I'm around 129,000 miles now. The biggest problem was a transmission failure about 2 years ago around 95000 miles. No warning, just failed while driving down a back road. A reman GM transmission installed and it's been fine ever since. A few other minor problems along the way. I am in no hurry to replace it. It's been paid off long ago and do plan on driving this as long as I can.   I will admit I am leery about all the additional electronics in the newer models and feel that it is just more potential problems. I think there's actually more than I would have wanted in this 2016 but so far so good. I think even if something major like lifter failure happened, it would still be cheaper to at worst, drop a new engine in than buy a new vehicle.

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences.
