Sense its a GT I am going to assume it has a 3100 engine and the PCV is under the intake. You can replce it but unless you have over 150000 miles on it you probably don't need to. They hardly ever give any problems on those cars. If I am not right about the engine let me know and i`ll give you the you need. Ray
On my '99 Grand Prix GTP SuperCharged. + Standing in front center of the car + Remove the plastic cover + On TOP, the back right hand corner, there is a small flat plate with 2 small bolts on it. + Remove 2 bolts, lift up Plate and Gasket + Remove Spring + Remove PCV with O-ring + Put O-ring on new PCV and put PCV back in hole + Put Spring back in hole on top of PCV + Replace Gasket and Plate + Tighten down the 2 bolts + Put Plastic Cover back on and tighten nut. I would change it(PCV) out every time I changed the oil. PCV's only cost about $2.50 and keeps your car motor from building up too much pressure and keeps your car from getting oil leaks. Also I personally use Mobil 1 oil. Now drive it like you stole it! Dexter
Every Grand Prix GT I have ever seen had the 3800 engine in it, usually supercharged, that's why its called a GT. The standard run-of-the-mill SE models have the standard 3100 engine in them. BUT,...if you buy a car new, DIRECT FROM THE FACTORY, then a person could order their car with either engine! If you got the money to burn, a person could have General Motors drop a V8 in their SE or GT model
