Thank you all for the new ideas, and i'll check them out. I did the intake first, with the engine in the car. With both the intake and the valve covers on the work bench, and the engine obviously at rest, there was still
oil leaking from the engine, onto the shop floor. So, it can't be from either of those two places, but it could be from one of the others, and I'll check those. Thanx again...I'm learning a great deal from this (somewhat difficult) exercise. s
