I used to have trouble with oil blowing out of the valve cover breather on a 1/4 mile pass. I had a pcv valve in one valve cover and a breather in the other. What I did was replace the breather with a breather that had a big 1/2" or 5/8" hose connector on it. They have foam in them for a breather and I pulled all that out. I connected that hose to a hose fitting on the base of my K&N filter so that when manifold vac dropped off at full throttle, I would have vac on the crankcase from all the air being pulled by the carb. Worked like a charm and I have never seen any oil since.


I used clear tubing as well so I can see if any oil is being pulled. So far, nothing.

Interesting. I'll have to look into that.
