Cover your distributor with saran wrap and give your engine a bath, then get back to us with exact location and amount of leakage. 20/50 sounds good in any case.

I would not recommend pcv . The 37 uses no rear seal so youd be sucking dust from the clutch area using a pvc

You need to do as suggested. Clean the motor and be more specific, picture will help

Maybe start by tightening the bolts on the oil pan, timing gear cover, distributor, etc. and see if that makes any difference.

What mcgarrett said x 2, but do not over tighten the pan bolts.

A 20/50 is no more then a 20 thought all operating temp go to a 30
