5.7L


The PCV valve (3) is mounted into the top/right side of the intake manifold (2).


1.The PCV valve (1) is sealed to the intake manifold with two O-rings (2).
2.Remove PCV valve by rotating counter-clockwise 90 degrees until locating tabs (3) have been freed. After tabs have cleared, pull valve straight up from intake manifold.3.After valve is removed, check condition of two valve O-rings (2). __________________

The valve is located under the thermostat housing facing the front of the car. There is very little room to work with here. You'll have to pull the hose up from the valve then pull the valve out.

 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. 

3.3 and 3.8 engine pcv valves are it the rear head valve cover. they are a pain to remove

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.
