I have a 1992 Ranger with a 2.3L. Where is the PCV valve?

let's see. It's basically in the back hanging (it's an inline pcv). If you feel under the upper intake and find a rubber hose, then follow it to the back and down, you will find it. The PCV you buy at any parts store is the correct one, but you have to pull off the angle piece. It's a little tuff but it's possible. :)

I had a problem with finding the correct PVC valve with the auto stores here in my town. Make sure if they give you the wrong one have them try to cross reference it. But then at autozone even after the crossreferenced it they still couldn't get the right one. But I was lucky that at napa they were able to find the correct one after referencing that one.
