I recently replaced the CCV plumbing on my XJ since I was having problems
with oil blowby into the air cleaner. Anyway, the rear valve cover grommet
doesn't mate up with the elbow. The grommet I've got is round while the
elbow fitting for the rear vacumn line isn't! Is it possible to buy just a
new grommet or do I have to buy an entire new valve cover?

Hi Doug,
All those grommets are found on the display racks at most parts
stores.
The blowby tells me you still have a problem with a clogged orifice
solenoid at the base of the throttle plate. Chuck it, and convert to a
regular Positive Crankcase Venation valve like at:

You have a new elbow, and it's not round? There
should be no reason to replace any of this system
unless it's broken, there are no wear parts. When
you notice oil in the airbox, you have a plugged
orfice. Clean the orfice and your job is done.

Let's get clear... is the elbow new? Is the grommet
new? Was the old elbow plugged up? Did you
already throw it away? Was the old elbow round?

I think we can safely say that you don't have to
buy a new valve cover.

I don't have a clogged orifice in the rear valve-cover CCV plumbing because
it's not really connected at all. That's the problem the grommet in the
valve-cover doesn't match up with the CCV elbow fitting. The grommet in the
valve cover is merely a round hole whereas the CCV elbow fitting is designed
to be rotated and locked in place (kinda of like the oil filler cap) rather
than just plugged in.

The CCV plumbing is all new because I was having oil blowby into the air
filter. The problem is the rear valve cover CCV plumbing never fitted so
there's plenty of room for a vacumn leak and I'm pretty sure nothing is
being ported from the valve cover to the intake manifold because the
connection is so loose.

Because of all the above I'm thinking Jeep/Chrysler/Damniler must have
changed either the rear valve cover grommet design or the valve cover design
since '91'.

I think I'll look into Bill's idea and see if I can find and elbow that will
mate to the existing grommet and CCV plumbing.
