Ok, This part is pretty hidden. On the series II engine. It is under the plastic cover. Take this cover off. Now on the passenger side is a black box with wires coming out of it and a numerical code and a bar code on this box. Now there is a twist clip on there. Compress this clip and then twist. The PCV valve is under this clip. Be careful not to break this black box. IT IS ATTACHED!!!! If this box is broken, the check engine light will come on. So be careful! Good luck!!
The PCV valve on a 2002 Pontiac Bonneville is located on the back of the in take manifold, however to get to the PCV valve you will need to remove the valve cover.
