ON the valve cover in the left top corner i have that threaded hole open aswell and no problem...but i think on that year.. the PCV valve is located there...haven't looked at the 97 and older 2.2 reacently...sorry...

ya your right the pcv valve is located in the top left hand corner of the valve cover. The threaded hole is in the middle of the valve cover right at the front of it
