I tore down my valve cover. to clean and paint. now I can't find parts. does anyone know the part numbers for the CCV front and rear grommets /elbow . . and for the gaskets for the valves In side the ccv tunnels.

I bought gasket paper and just made new ones.

cbheternal

that was plan B for the tunnel gaskets. lol. but the real problem is finding the ccv grommets. the dumb *** at the dealership. can't find the parts. other than a kit that costs 250$. I just want the new grommets. any ideas. ( wrecker ). jeep stuff is hard to find here.

cbheternal

could I use rtv sealant instead of paper gasket.

XJ Stryker

Oh and they have those grommets at autozone, advance all those places.

When i asked for them i took the guy out to me jeep and showed him what i meeded and he got them for me

XJ Stryker

I didnt. It had gaskets and it is only a matter of tracing and cutting.

cbheternal

I'm in Canada. no go at Lordco. and Wakefield. I'll try some other places. one would thing the dealership would have made this a easy project. Nope.

Canadian tire...help section. Same on my renix...just improvise. That's the Canadian way lol...

cbheternal

crappy tire eh? it's worth a shot. alder auto. seems to be the most help so far. the hunt continues. cheere

DFlintstone

Agreed ^^, like hank points out, there are grommets out there. I found some in the drawers at ACE.

I don't think inside the valve cover the gaskets are necessary. You might look at Cruisers valve cover mod for Renix in my signature.


Looks like you are in "fighting trim" there Hank Lol!


Of course I have the end of this routed to the air cleaner. The next thing I might do there is put a little "window section" just downstream of the ccv orifice. Somewhere I have a little 1 in dia, 3 inch fuel filter with a glass cylinder. I might remove the element and install that...for fun. A second stainless/w zip tie bracket would take some stress off that front grommet. VV

Not sure if you've used Rock Auto. They have a Dorman part

I just bought the grommets today for a 96.
The NAPA # is 630-1410, marked "Breather Grommet-CHRY"
The MOPAR # is 2946 079
It's the same for front and rear on mine and I'm pretty sure this will work for the front grommet on yours, but the rear will be different.
On older models, the orifice is built into the grommet, like the one 67GMC posted.
(on mine it's built into the rear elbow)

For some reason I'm remembering my 89 having a PCV valve at the rear rather then a CCV, but I could be wrong on that or maybe The US and Canadian models were different.
...and I couldn't tell you what would happen if you switched from a PCV to a CCV set-up on that motor.

DFlintstone

A little trivia. (from the FSM for 90) The CCV orifice on the 4.0 is 2.6mm. It has a spring/plunger that limits the flow at high vacuum, but lets more pass at medium vacuum. It also blocks backfiring.

Now knowing that, I want to clean mine in case it's not closing down for high vacuum. Seems like that could gum up easy, and it wouldn't surprise me if they didn't tend to end up sticking, "Open".

On your 89, the front grommet is actually a fitting that reduces to the plastic line to the air cleaner. Only way to get it is with the vacuum harness and it's available at Napa.
