: engine oil in intake manifold

03-10-14, 09:31 AM
Anyone experienced engine oil in intake manifold on Seville 1996? Any idea what could be faulty? Currently we have removed transmission with shifting problems. Engine has 78000miles.

Nothing is faulty. It's normal EGR and PCV gas deposits that settle out after the engine is shut down. Ugly, but harmless.

Yep ^^^^

PCV vapor deposits. Normal. Pre-2000 with rattle valve and pre-1998 with different TB piping will get dirtier.

When i replaced my starter not too long ago, i had a bit of a mess in the valley. And this is a "newly built" from the ground up Northstar, all new seals and gasket. I wouldnt be concerned.

I had the same thing in my 1998 Deville, when I was cleaning the throttle boday. Nothing to worry about.
