Where is the PCV valve on a 1991 Chevy Celebrity?
On the V-6 model, the PCV valve is a real pain to replace on
this motor. The valve itself is located on the rear valve cover.
Getting it off is a pain cause its such a tight area, and because
the hoses are usually very brittle, and break. If this happens, you
have to take off the upper intake plenum to replace the hose. This
in itself can be a pain cause of the hard plastic vacume lines that
are located around it. As much as you want to do it yourself, I
almost recomend taking to a dealer for this. That way if they break
it, they pay for it. Unless you are mechanicaly inclined
