When you open the hood and are standing in front of the car, at the left end of the vavle cover, which would be the pass. side, there may be a clip to hold the plug wires on it. There are probably two bolts on a flat cover, remove the bolts, you may have to gently tap the cover to break it free, it does have an o-ring seal and a spring under the cover. Use a pair of long nose pliers to grab and gently pull up to re move the old pcv valve you may have to use the pliers to install the new one, then spring and replace the cover

The PCV valve should be on top of the valve cover at the back. The valve just plugs in, and slides out of the rubber hose.

Do you mean the PCV (Positive Crankcase Ventilation) valve? The PCV valve should be on the top of the motor, either in one of the valve covers or in the coverplate on top of the block.
