I have this problem ever since I blew a head gasket, oil comes out from the distributor O'rings, lower intake manifold bolts and pours from the rear main seal, has PVC valve and breathers on both valve covers. Lost about 2.5 quarts of oil in 500 miles
Prokiller, with issues like that, I would forego formalities too.
Are you sure you dont have a crankcase ventillation issue still? I would remove the oil filler cap and see what happens (if you have 90 MPH wind coming out of there, that aint quite right.
There is either still a ventillation issue or serious ring issue IMHO.
