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.
You can find the PCV valve beneath the MAP sensor located in the plenum at the right front of the engine.
No PCV valve on this engine. Has "PCV system". Hose from valve cover to throttle body. Nothing to replace.
the 89 with the 360 has the pcv valve in line behind the carburator.
The PCV valve on 1987 to 1990 2.8L or 3.1L engines is in the top center of the valve cover by the firewall. It is under the plenum so it can be a little hard to see and get to.

The PCV valve should be on the passenger side valve cover, about halfway back.On a few models it is on the back of the engine mounted to the plenum.

Follow the little hose from the front valve cover to the intake manifold. The part it hooks to on the intake is the pcv valve.
Not sure about the 1989, but 1990-1993 it goes into the valve cover. Look for a hose running to the valve cover and the PCV valve should be what is at the end of it pushed into the valve cover.
