Needle bearings in oil pan.....
 

Chad, did you ever get that problem with your LS1 worked out?

Cause I had my oil changed today (along with a new fuel filter), and there were about 10 needle bearings on the oil plug magnet when they pulled it out. A buddy of mine thinks that one of my rocker arms is damaged.....we're gonna take off the coil packs & valve covers tomorrow and check them out.

Supposedly this is a common problem......anyone else have to replace a stock rocker arm?

Yeah I got mine fixed, it was just a misfire.

needle bearings...in rockers??? i dont think there are any neddle bearings in an engine...

aren't roller rockers needle bearings? The big thing though is if the bearing came apart that cylinder would be dead, and youd have a ses light from teh missfire

if maybe theyre full roller they might have a needle bearing in em...but do ls1s have that?

Turns out I had a busted rocker arm.....a buddy of mine helped me fix it, and he also discovered I had a rather large vacuum leak. Some electrical tape made for a temp fix, then I got some flex hose from Autozone to replace it.

Got those 2 things taken care of, but now I have an unholy rattling from the exhaust....plus a noise that sounds like a bad exhaust leak. D@mmit, its always something.
