PCV valve on a 1991 Wrangler

I also had another question...

When I took my Jeep in to get an oil change, they said it needed a new PCV valve. I bought one, thinking I could easily put it on myself. But I can't find it!!! I did some research and several sources said that it has a CCV valve, not a PCV. Is this true and if so, where is the CCV valve?

hey, it is technically a ccv i think. if you look on the very top of the engine (valve cover) there should be an elbow at the front that has a hose going to the air box and an elbow at the back going with a vacuum line on it, that one is the ccv
