There are two locations depending on which engine you have one of the valves is in the right valve cover while the other location is in the left rear of the valve cover. Check out the diagrams below to see what I am talk about

CAUTION:DO NOT remove PCV system from engine. Removal of PCV system will adversely affect fuel economy and engine ventilation and result in shorter engine life.

The Positive Crankcase Ventilation (PCV) system cycles crankcase gases back through the engine where they are burned. The PCV valve regulates the amount of ventilating air and blow-by gas to the intake manifold and prevents backfire from traveling into the crankcase. The PCV valve is designed with a quarter-turn cam-lock thread at one end to prevent accidental disconnection from the valve cover.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

If you stand in front of your car, look on the rear right side of the engine head cover where you will see the ruber hose elbow that connects to the side to the rear of the engine head cover. The PCV is mounted from one side of the elbow hose to the engine head cover. The PCV is mounted directly to the engine head cover. To remove it, pull the elbow rubber hose off the other side of the PCV and twist the PCV on the head cover counter clockwise to remove it. Make sure you clean the inside of the hose and the wall of the head cover before you put the new one on.
Good luck,
Tran

On the hose that goes from the valve covers to the throttle body or intake air cleaner, check the rubber boots, the valve may be in there or it may be in the middle of the hose that leaves the valve covers.

I would like to change the PCV valve on the vehicle but can't seem to locate it. Would you recommend changing it and where is it located. It is the original equipment.

Thanks

On the 5.0 v8 it is located on the back of the intake manifold. On the v6 it is located on the valve cover near the brake booster.
