What did you expect him to tell you, the truth?

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.
