There is a great write-up with pics on how to change the PCV valve at: http://macgp.clubgp.com/howto/pcv/pcv.html Hope this helps. G
I KNOW TRYING TO LOCATE THE PCV ON 2004 GTP IS FUSTRATING, I HAVE THE SAME PROBLEM! SPEAKING TO THE PONTAIC DEALER I WAS TOLD IT IS LOCATED ON THE DRIVERS SIDE, ON THE SUPER CHARGER. GOOD LUCK!!!!
The PCV valve is located under the MAP sensor on a 1990 Pontiac Grand Prix. The MAP sensor is in the upper plenum.
In the valve cover at the right front corner
For pics and instructions for the Grand Prix GT check out. http://macgp.clubgp.com/howto/engine/pcv/gt/pcv.html . "G" It is in the intake behind the throttle boly.
PCV Valve LocationI just changed mines recently. Remove the top cover. It should be located on the left side (passenger side) next to the fuse box. It has a plastic covering that reads sensor. Look for the wiring. That's correct if its a Grand Prix GT. If you have a Grand prix GTP supercharged engine, the PCV valve is under the black plastic engine cover which comes off by removing the oil filler plastic tube and lifting up and forward. Look to the back right corner of the intake manifold when standing in front of the car and you will see a small metal cover with two bolts. Inside is a gasket, a spring, and the PCV valve. Be careful and keep it clean.
The PCV is a small metal cylinder the is plugged into the top of the valve cover and has a 1/2" coming out the other end.

Yes, a person can get a diagram of the PCV valve location in a 1989-1999 Mercury Grand Marquis. This diagram would be located in the maintenance books found in auto part stores.
For all GTPs 1997-2003, the first step is to remove the cosmetic supercharger cover. At the rear of the motor, on the driver's side of the vehicle, there is a small plate etched with "PCV." Use a small socket and ratcher to unscrew the two bolts, and the PCV valve will be exposed. The PCV valve may stick, so you may need needlenose pliers. Remove the valve, and do not lose the corresponding spring. Simply put the new valve with the spring in and reinstall. Hope this helps!
It is the Positive Crankcase Ventilation (PCV) valve.
it is on the rear valve cover.very hard to get to..The pcv valve is not visible on a 3800 series II engine, which I presume you have in your Grand Prix, because it is located under the MAP sensor. You will find that at the front of the engine, where the serpentine belt is located. Unplug the connector to the MAP sensor and then you will have to unclip the sensor itself. You will then see pcv valve underneath.3For a 3800 normally asperated check out the following website for pics and instructions. http://www.scacgp.com/mods/gt_pcv.htm."G"
The 3800 in the SE is the same engine as in the GT. Check out the following website for pics and instructions on how to change. http://macgp.clubgp.com/howto/engine/pcv/gt/pcv.html Hope this helps. "G"
Take the cover off and the PCV valve is inside the black plastic thing on the right (passenger) side of the engine. Press down and twist off the cover. Be careful, though, they break easy.
Replace spark plugs and wires Replace fuel and air filters Replace PCV valve

The PCV valve on the 2002 3.8 Liter Supercharged engine (in my case it's a Pontiac GTP) is located under the plastic cover at the top of the supercharger towards the back. A oval shaped black plate covers the PCV valve. The plate is secured with two bolts (10mm). Some report problems with regards to the integrity of these bolts so be careful not to over torq them when re-installing them. Recommended torq is 78lb. There is a spring pushing against the bottom of that plate that holds the PCV valve tight against its rubber seat. There is also a gasket between the black plate and the supercharger housing. Replacing that gasket is also a good idea when replacing the PCV valve.
on a 1998 Pontiac gan am ,they do not have a pcv valve.
depending on which motor you have 2.0 in the valve cover 2.5 at the rear of the drivers valve cover
The PCV valve on a 1999 Bravada is located near the oil filter. It is on the passenger side of the engine compartment.
