Clois,
I've had your problem too. I have a rear breather, a front
oil fill breather and two valve cover breathers. Solved the problem with no detrement by placing some "Scrubbie" stainless element in the
oil fill breather tube. Ask you Missus to find you some at the supermart. It's sorta like Brillo, only stainless threads. Cut off about two inches worth and gently pull apart, then insert into fill tube. Traps flying
oil but lets out crankcase pressure. No Splatter. Remove to add oil then re-install.
Hope this helps. It works well for me. And I have .090" restrictors.
Good luck,
