Best Answer

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.
