Title: Oil leaking??
Post by: binjeepin on September 10, 2009, 09:40:40 AM

I just picked up a 90 YJ with the 2.5 4cyl. It is leaking oil into the air cleaner box through a little hose that I thought ran from the PCV valve. I took the 'valve' out only to find that it is only a vent type thing. No check valve or ball in it at all. I suspect some blow back from a posibble valve problem. Any suggestions before I go and tear the head off of this thing and get a valve job done??

I was just reading an artical on this last week, this is based on the 4.0L, but might steer you in the right direction???
HTH..

That sounds like an easy fix and describes what is happening woth mine. I think that it should work on the 2.5 as they share similar systems.
