PCV Valve in 94 4.0L?

I have a 94 YJ with the 4.0L. I followed the Haynes manual and tried to check my PCV valve. First problem, when I was trying to pull the stinkin elbow off, I broke the cheap plastic. Anyone know where I can pick up a PCV elbow (the part that goes from the hose into the engine)? And to add insult to injury, there was no valve there to check! Should there be one? I asked the local auto store and they said there isn't a PCV valve. But they also told me that there isn't an elbow either. I've got the pieces to prove the elbow exists. Any help is appreciated.

Take what is left of the old one to the local parts store. They should have what you need.

I believe that you don't have one. I think that the 90's engines abandoned the PCV for the CCV .........which is a metered orfice (the metering valve is on the manifold). I'm not sure why they did it ..maybe the use of air/fuel valves for idle had something to do with it.

Go to NAPA ..they have one of those rotating rack/stand thingies with every known plastic part.

on my chevy I broke the elbow on my PCV valve. I replaced it with a section of hose. This was a "temp. fix", but that was 6 months ago. It works good and I see no reason to replace it.
