off-topic - '85 Chevy RV oil leak at oil filter adapter

Re: off-topic - '85 Chevy RV oil leak at oil filter adapter

All - sourced both the GM gasket and the FelPro kit ($10 at AutoZone) - turns out that this system does use a gasket as well as the o-ring. As noted, the gasket was mostly hardened, and required quite a bit of scraping. The most curious part was the condition of what used to be the o-ring. It had turned into a hard, blackened, flaky mass that seems to have extruded itself onto the inner surfaces of the oil filter adapter. This can't be what GM had in mind for this material...

Good news is - leak fixed! And, since I had lots of stuff out of the way, fixed a small exhaust leak with a new gasket where the pipe joins the exhaust manifold.

Thanks again to all for your support.

in the 20+ years that "O" ring has been in there the composition of the oils has changed and the newer oil may have attacked the "O" ring. even in 1985 they had viton "O" rings but they would have cost GM 5 cents more so they did not use them. this is why GM is in so much trouble,stepping over $$$ to save pennies

I'm glad to hear you got it fixed. Since you didn't mention any difficulties, I take it the job went well. Congratulations.
