92 S10 CPI oil pooling in my plenum ?

[Mr S10]

Ok so I take off my plenum to check to see if I had a gas leak, The good thing is I didnt have gas pooling. But I had oil pooling in the corners of the intake plenum, what is this from is it bad?

Just tryed to have my 92 s10 Blazer 4.3 Vin W Smoged didnt pass can this have been one of many reasons

What can cause oil to pool in there?

All my spark plug are new and still clean after 400 miles

Dose not use oil or smokes. Put 5 quarts in and get 5 quarts out. im using 10w/30

The oil in the plenum is like black slug my motor is normal light tan not worn oil looks new and never had black or dark oil. I change it often.

You have been helping me on my other Thread (Exhaust value no sealing 4.3 Vortex)

the PCV test is more than a rattle. sometimes they are worn and allow toomuch vapor to be sucked.
