When L31 heads and aftermarket cam are mentioned in the same post, I begin wondering about whether or not the builder actually prepared the heads for more lift or not. I'd be pulling a spring off an intake valve to inspect the seal and see if it's been smashed into submission by the underside of the retainer or not.

No. 2 possibility....oil rings not installed correctly.

No. 3 possibility....intake manifold not sealed to head ports, motor sucking in oily vapor from crankcase on intake stroke.
They are summit racing heads, and had an additional bill from the machine shop for porting after initial porting.

I wasn't sure if the vortec style intakes were at the same risk for gasket issues as a standard style intake. Is there anyway to accurately test this before i break out the sawzall to try and the dist and intake out? It really doesn't look like much fun in an S10 lol.
