I will assume you you have the Duratec engine (24 valve). It is located under the intake manifold on the transmission side of the engine. Real tough to get out without some real long pliers with a ring type end on it. It needs to be twisted counterclockwise to release it. replace the hose to it while you are there also , they degrade and will cause a vacuum leak.

the pcv is located on the rear(firewall) of the drivers side valve cover.turn counterclockwise and pull to remove be careful there are 2 small tabs inside the pcv hole in the valve cover(can feel with small finger) this is to hold valve in place so it wont leak.if you have a oil leak at the pcv a quick fix is to put a small amount of silicone around the pcv o-ring and install.wait hours for silicone to set up.

it is down under the intake manifold. the intake manifold must be removed to get to it. this vehicle is known for developing a vacum leak in the elbow hose that connects to pcv valve, so ive done a few.

rough-idling engine can signal a number of positive crankcase ventilation (PCV) valve problems, such as a clogged valve or a plugged hose. But before beginning the functional checks, double check the PCV valve part number to make certain the correct valve is installed. If the correct valve is being used, continue by disconnecting the PCV valve from the valve cover, intake manifold, or hose. Start the engine and let it run at idle. If the PCV valve is not clogged, a hissing is heard as air passes through the valve. Place a finger over the end of the valve to check for vacuum.
With the engine at idle, vacuum should be felt at the PCV valve.
