Hey MM==As far as I know it is like the rest of the 3800 engines and in in the intake manifold. There should be a hose going from it to the throtle body. Good luck Joe To replace the PCV valve: 1) Remove SC plastic shroud, 2) Note the black plastic PCV cover about 3 inches to the right of the shroud bolt, on top of the SC/Intake Manifold. It does not have a hose connected to it!! 3) Remove the 2 10mm bolts and lift off the PCV Cover. 4) A hold down coil spring can be removed and 5) the PCV valve sits in the recess. Reverse assembly with new PCV valve. With this location DO NOT EXPECT big change in operation - the old valve just gets a little varnished...
