Need help finding this
 

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.

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 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.
