The PCV valve is located on the passenger side of the vehicle about center of the air collector system cover. It's right on top and easy to see and replace. Just remove the hose connected to it and screw the valve out of the intake manifold. Install is the reverse. You may want to check the valve first before replacing it. To do this, just remove the ventilation hose attached it and start the engine. If you hear a hissing sound coming from the valve while the engine is running, the valve is good.
