I'm trying to determine how they told you it was the one lifter. Hoping for the best but I don't think the shop actually knows the extent of any damage without getting into the motor. It sounded like they pulled the heads to get to the lifters and put it all back together so you could go pick up the car.

Good idea to check them. 8000rpm could fatigue the stock springs and end up dropping a valve in the future. With heads off it shouldn't be difficult to change them if you dont have access to shop air. Buy a spring compressor and do it on a bench. Cheap insurance. Are you upgrading the cam? If so i would use new lifters as well. Best of luck op. Remember it's just a machine, it can be fixed.

I'm just hoping since the speed wasn't absurd and the engine RPM had to be under 7750-8k, that the damage was very minimal and that one cylinder was the only thing affected. Other than that I have read these engines are pretty damn tough so I'm hoping that's the case. |

Stupid question but I doubt the warranty covers an accident like this correct? lol

If they know the failure was due to a mechanical over-rev, unlikely..

If gm has a tech pull the heads or the scope the cylinder and find valve marks on the piston tops then they could deduce a money shift which i believe is not covered unfortunately.

Update: Car is back, a valve was bent in #3, there was a very very small nick on the piston supposedly. Replaced it, CEL is off runs great, put about 100 miles since I got it back haven't heard any abnormal sounds or anything. I was paranoid about 2,4,6,8 cylinders since that side wasn't really evaluated to my knowledge but it's not down on power, no weird noises...so I think I'm in the clear. I was thinking of doing a compression/leak down test on that side just to calm down my paranoia but just looked at the engine againit's pretty intimidating to say the least.
