!!!!!!! 91 4.0 oil leak !!!!!!!!!!!

I was wondering if wranglers have a pvc valve that needs to be cleaned out after a while, its leaking oil from the top of the valve cover where the oil cap and also the breathers that go in to the air box ,not extreme amounts just some, I had heard that if you clean the pvc valve this will stop, but i noticed 4.0 dont have it or at least i havent seen it, this has been going on for a while, any good thread you guys have or advice is great thanks....
