I bought a set of aftermarket valvecovers the kind that come without any holes. I put a push in
breather in one cover. Should Ido the same with
the other or cut ahole and put in a pcv valve?

PCV valve if it will see alot of street miles. I run two KN push in breathers,no pcv,one in each valve cover and the valve covers stay suprisingly clean with low tension oil rings. This was on a 30-40 roundtrip to town.

I did the same thing and I had a K&N push in breather in one valve cover and then a pcv in the other the only thing is there arent any baffels and once the engine heats up, I get a oil coming out around the breather but not the pcv. That the only problem Ive had have any of you had that problem? If so how did you fix it? Thanks a lot.
