location and removal of pcv valve

On the passengers side top of valve cover at rear near fire wall, Just wiggle and pull straight up, replace or clean with throotle body cleaner and if you can get the vacuum hose off and back on clean it out too, just push it back it same as pulled out. You did not say which engine but the one I have seen are in the same place. Give it a few shakes up & down quickly to hear if its working.
