Paul,
On very back of block in lifter valley is a hole that from the factory had a oil separator (baffle) which pushes into that hole (approx ! 1/4 hole and then a 7/16 head bolt holding it in place. Then that hole ends up coming out behind block on outside, right behind dist. Is that hole plugged on the outside of your block or do you have vacum on it to try and get rid of windage pressure inside motor? If you have vac on it, without the oil separator (baffle) in place it will suck oil like crazy.
