looks like a pain to change. Plus, I had a hard time finding it. i thought they were usually up on the valve cover somewhere. Anyhow, getting to that bottom hose connect is looking tough from the top but its looking like its its gonna be tight getting in from the bottom also. I am gonna have a reason to raise the car fairly soon (torn cv boot). Is it easier to get to that bottom hose from under the car? 93 DX HB by the way.
Look at your intake manifold... On the front of the plenum (the part that distributes air from the throttle body to the 4 runners) there should be 2 or 3 vacuum lines. One of them is larger than the other(s) and runs down to a plastic elbow stuck in a holder between two of the runners. That plastic elbow is the PCV valve.
I may get flack for this but I've never bought a new PVC valve. I always just use carb cleaner and clean it till it rattles.
$.50 worth of carb cleaner from a $1.99 can or $5 for a new PVC valve. It makes sense to me.
haha.....I have done that also several times, although I usually just get a new one since they are not expensive and don't need to be replaced often..Then I saved the old cleaned out one for a spare. So let the flack begin.
