Pcv valve
I was have a 89 cherokee with the 4.0. My local parts store can not get a new pcv , but was told there is a way to mod ur own. Any one on here know how.

The pcv valve in front has the large hole while the one in the rear has the small orifice. The one in the front usually is the one that is hard to get. Just buy an extra rear and drill a 3/8th hole in it.
