It is not a PCV valve guys....
It is a CCV grommet with a hole in it. They are two different systems.

Bill and Mike,
The kit comes as you descrbed it Bill. I have it on my CJ also. ALL original
CJ 258 (4.2l for you metric types) smog/PCV etc kit gets trashed. The whole
system is from the 4.0l system. Bill, your system isn't broken it's
installed exactly as it's intended to be installed. It may need some
cleaning/part replacement. Also as previously stated make sure there are no
leaks in the system. It will upset the apple cart.
Bill, if you need I can take pictures of my system and email them to you.

Re: Can the PCV Valve on a 4.0L Valve cover be cleaned or replaced?
Rich,
Mike's statement regarding my kit being broken (I bought it used) comes
from a succession of things we've discussed in the past. This leads him to
believe my kit is broken (gas wash or blow by issues). He believes my
engine has/had gas wash caused by leaky injectors. Also that my Charcoal
can could be bad (blowby).
I am thinking either the previous mechanic rebuilt the engine and didn't put
it back correctly throwing off the O2 sensor causing a rich burning system.
This causing the engine problems. (Only about 40k since the rebuild)
Or
The thing was never rebuilt as I was told and so it's just aged. (the
machinest did say he felt a ring ridge on the cylinders)
I don't think I had the MPI kit on there long enough to do the kind of wear
we're talking about.
However I've learned a lot from Mike and respect his input so just to be
safe I am going to get the system checked out after the rebuild.
Thanks for the offer of pics. I'll let you know when I get to that part.
