The front top valve cover has 2 pieces (main cover and pcv cover). The PCV is located under the small cover (has a 6 inch hose attached to it) on top of the front valve cover . If you look at the front valve cover, you'll see four (4) bolts. The two outer bolts fasten the valve cover to the cylinder head. The two inner bolts hold the PCV cover to the valve cover. To gain access to the PCV valve, you remove the two inner bolts and remove the PCV cover, leaving the valve cover fastened to the cylinder head. It might take some "persuasion" to get the cover off. Once you have the PCV valve cover off the valve cover, there will be a large square seal (looks like a big o-ring) that seals the perimeter of the PCV cover. There will also be two o-rings that seal the PCV cover bolt bosses to the valve cover. The PCV valve is located on the right side of the opening. You can't miss. Just unscrew it and spray some WD40 on it and work it around. Pick up another PCV cover o-ring and the two o-rings located underneath the cover bolts (3 seals total) at the dealer or parts store. They're probably hard as stones by now.
