I’m having trouble finding the replacement front breather vent 90 off the valve cover. The one I bought for it is too big for the hole. The one that was on it was all brittle and fell apart when I removed it. I can’t find the replacement anywhere, even the dealership was of no help. Hoping someone on here has an idea. Cherokee is a 1990.

I have no experience with the older 4.0's but from my '88 to '90 parts catalog

14 GROMMET, PCV

5300 4722 1 Gray, 2.6mm I.D.
5300 4721 1 Black, 2.2mm I.D.
So I am guessing black goes in the front and gray in the back.

So do yourself a favor. Read this:

Having parts catalogs can be helpful.
Also for your viewing pleasure.

RENIX VACUUM HARNESSES

NOVEMBER 17, 2015 SALAD 17 COMMENTS



The vacuum harness that attaches to the front of the valve cover and includes the grommet/fitting, and is called the front harness, is Napa part number BK 715-1367 or is a Dorman 46003.



The vacuum harness that is closest to the air cleaner, EGR etc, and is called the rear harness, is Napa part number BK 715-1366 or is a Dorman 46004.



The tube from the rear of the valve cover to the intake manifold is part number BK 715-1365 or Dorman 46005 and comes with the valve cover grommet.

The Throttle Body to MAP hose is no longer available. Click HERE to access a fix for that.
