The 2005 Grand Prix Base model and GT models have 3.8L's and the GXP models have the 5.3L V8. I know the location on the 3.8L.
- Take the engine cover off
- Look at the very top of the motor, the intake manifold.
- There are fuel rails running over the top of this manifold.
- There is a bolt holding 2 of the rails in place right in the middle.
- To the bottom right of this bolt is the PCV valve.
- It has two bolts holding it in and no lines running to it.

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

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.
on a 1998 Pontiac gan am ,they do not have a pcv valve.
