It is on the driver side engine valve cover. Its a small part,

There is a short L shaped (right angle) hose about 1/4 inch in

diameter connected to it. Lift up on the hose and it should

disconnect from the valve cover. the small metal cylinder should

pull right off that hose. Thats your PCV valve.

Note: there is a similar hole on the opposite valve cover, but

that has a larger hose that connects to the intake. You can use

this as a reference to find the PCV valve on the driver side.
