Where is the PCV valve on a 2000 Pontiac Grand Prix?

Answer 1

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.
