Found my oil leak, need some help finding something

[fly89gta]

Ok, it appears my oil leak is coming from where the oil filter housing meets the block, looks like there is a gasket or 2 and a few O-rings, its leaking from that whole area, does anyone have the schematics or pics of the gaskets and stuff?

I need to give em to a friend of mine who is going to get the parts need to stop this damn oil leak


As always its much appreciated

BTW I searched gnttype.org and couldn't find anything

Just really need to know the gasket arrangments. Pics would be GREAT

The oil filter seals to the oil cooler adapter using the gasket on the face of the filter. Make sure the mating surfaces are clean and that you put a fresh coat of oil on the filter gasket using your index finger before installing.

The oil cooler adapter seals to the oil pump cover with o-ring P/N 25530999. Make sure that the retainer (the fitting onto which the oil filter threads) is tight - they can loosen when you remove the filter.

The oil pump cover seals to the motor with gasket P/N 25512860.

Tell your GM counter guy to pull up the "1986-87 "G" Engine Oil Cooler Pipes & Filter V6 (LC2/3.8-7) illustration in Group 1 - you'll see everything there.

Likely it's the o-ring - and Kirban and others have slightly thicker, replacement o-rings for this application.
