Hi - My vote is for venting. Add more vents!!! Oil pushes out because of p=
ressure in the block. Give the pressure somewhere to go and either you get =
less leaks or no more leaks (depending on the state of the engine).
I think Kas covers this pretty well in one or more of the books.
;-)
By way of example, I run two 1/2" vents in the valve cover and one via the =
fuel pump blanking plate, so three total. I also run PCV and a Goodparts oi=
l separator. As long as I keep the revs under 6000, the oil getting pushed =
out seems to be very small indeed, maybe a few teaspoons per session.
There's a common misconception about what gaskets do. They do not relieve p=
ressure and that's why you're pushing oil. Get rid of the positive crank ca=
se pressure and "Bob's yter unKle".
