Sorry it took so long my contact was on vacation. Your engine was built in Spring Hill Tennessee.

 

 

Thanks Firehawk99 I just crawled under and took a picture of my Julian tag and it starts with N and I was going to ask the same question. May 12th 2021 for me and Vin build date is 6/21 so it looks like it's running about 3 weeks to a month difference from engine build to truck build. Thanks again for all your info.

Anytime! Happy to help out.

In all reality it's not a major repair. Things just have to come apart to reach the lifters.   In total they replace a few gaskets and bolts. Them being 2 head gaskets, head bolt kit, possib

Any trucks built after 3-4-21 should be fine. That is the break point.

I work for GM at the Tonawanda engine plant. We build the 4.3, 5.3, 6.2 and the 6.6.

Back in the shop, after all lifters and a bent pushrod were replaced I picked it up and started shaking badly at about 40 mph and on light acceleration or when coasting. Was able to get it home, called my local dealer who said no appointments until 9/20 or drop it off and they will get to it when they do. Continued driving it as it wasn't horrible and no check engine light until I started smelling burning oil. Look under the hood and see oil pooling on the the intake manifold dripping down onto the exhaust manifold. Didn't have a choice but to drop it off at the point. Now waiting 5 days as it's a holiday weekend to be looked at without a loaner.  Take as long as you want to repair it, once it reaches a total of 30 days I will get and attorney and proceed with lemon law. GM is useless and their " senior rep" never picks up her phone. Horrible customer service.

My question is, what changed? Hardware or software?

can you confirm is this the lifter sound of a possible issue?  This is on a 2021 Tahoe with the 5.3

It sure sounds like it to me. I would park it and have the dealer come pick it up.

Cool, thanks 🙏🏽 luckily it’s on a vid I pulled from another forum. I asked here because at first to me it sounded like injectors similar to this video at 5:20+
