Re: List of LS problems. KISS
There's the piston slap issue, my 5.3 seems to have it on cold start, let it run for a few minutes and the noise goes away.
The ever popular exhaust manifold bolt issue. The OEM bolts "wear out" over time and break. GM also put Loctite on the threads so the best way to get them out is to weld nuts to the broken stubs and they come right out. I sold a 4.8L to a friend recently and all the bolts broke, I felt really bad but he was able to remove all of them using the welding method.
