Hi!
I have changed my LS1 98 trans am engine oil. Only 38000 miles. I found the metal parts of the pic in the oil drain plug...
The car runs smooth and perfect, also in high rpms. ONLY at idle you can appreciate slighty little noises like a free screw or something inside. No drops in rpm, but motor doesn´t have a uniform vibration. Can you help me?

Thanks!

Arnt those the bearings from the rocker arms? Pull valve cover and check.

Rocker arm needle bearings and what looks to me like torn valve stem seals.

You got lucky that everything fell straight into the pan. Is this a stock ls1?

Jurgen, is a completely stock LS1 with 38000 miles.
New rocker arms? Im in Spain. All parts are ordered to USA... I must be completely sure what part I need replace. This is the reason I posted the problem here.

Jurgen

here is a video on how to change the bearing with trunnion kit so it doest happen again . there is more videos if you search and you can do it urself . you take the bearings out of your rocker arms .
Good luck .
