Where is the PCV valve located on a 2004 Pontiac Grand Prix?
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.
