Remove the sight shield from the fuel rail. (it's the large plastic shield that dresses up the engine) As you stand in front of the car the alternator is located on rear left side. In front of it is an electrical connector to the MAP sensor. Remove it. Press the PCV valve cover down and rotate it 1/4 turn counterclockwise. It is actully on the intake manifold. Lift the cover, the upper O-ring and the spring from the housing. Remove the pcv valve and the lower O-ring from the intake manifold.
