PCV (Positive Crankcase Ventilation) is located on your valve cover, connected to a hose. There are two of those covers, one on the left and one on the right, only one cover has a PCV valve in it...............however, on some model the PCV is located in the valve cover, and a hose runs from the valve to the throttle body base plate (intake manifold)

The PCV will be left valve cover at rear facing up
covered by black hose. If it is the New style fixed orifice PCV Valve you do not need to change it. If it rattles when you shake it you need to change it.
