projectXJ: Quick valve cover CCV (PCV) repairs for pesky oil and vacuum leaks (96-01 Jeep XJ 4.0)

I have to do this bit of maintenance to my '87 Pioneer. Yet I chuckle as it does not have a "check engine" light. 😜

@@Mauser1965 it will definitely be different than what I did here, as the valves and seals I used apply to 96-01 XJs and (I think) the 4.0 ZJs.

The PCV valve is attached to the intake manifold.

I can't speak for every variant of the 4.0, but that's not a PCV valve on ours. It's just an open brass fitting that provides a hose attachment.
