It's Jeeps patented anti-rust technology.

Stops everything for rusting.

Re: leaking oil....

Wecome to the club. Seriously, it's a common problem. [img]images/graemlins/cussing.gif[/img]

Prior to my engine swap I tried a number of things, the best being to simply run a hose into out of the valve cover and into a one liter pop bottle. The pop bottle is held onto the hose by drilling a hole through the bottle with the hose inserted and puting a wire through it. Every once and a while empty the bottle and add some oil. Oh, if the hose is tight you will need to poke some holes near the top to vent the crankcase gasses off.

Good luck

Re: leaking oil....

How's the grommet look. If its cracked and brittle, change it, might save you from the "blow by bottle" for a while. [img]images/graemlins/grin.gif[/img]

Re: leaking oil....

JDog is right. Also make sure that the valve is good. Standard test is to shake it. If it rattles, it's good. Otherwise replacing it might solve the problem.

I thought I had a blowby problem once, and solved it by making a dual manifold. - Two PCV valves in parallel to suck more out of the engine. It solved the problem, but eventually I found that the problem was caused by something else. I still have the manifold, in case you want to try it.

JimLou, Can you post a pic of what you're talking about... I'm not much of a 'visionary' [img]images/graemlins/tongue.gif[/img].

Re: leaking oil....

PCV looks like it is ok. What could the root problem be? bad guides?? Any way, I will get a new grommit and hope that that works well. I have really never had this problem before, I replaced all the gaskets and always bragged that I owned the only CJ 7 that does not leak oil. Hahahah.. Now it does...

Re: leaking oil....

Here 'tis. It was easier to draw it than go to the shop and dig through the junk buckets. [img]images/graemlins/blush.gif[/img]

It's two nylon blocks with two PCV valves between them. The lowre nipple plugs into the valve cover, and the hose to manifold vacuum goes over the upper nipple.

It doesn't give twice the flow of a single valve because of the restrictions in the hose and nipples, but it gives a little more - maybe 50%.

If anyone wants to see if it will help, it's yours.
