This answer is false there IS a PCV on a 2002 Bonneville. It is located on the Intake manifold on the left hand side. There is a sensor mounted on top of it. You need to disconnect the sensor first, then twist the sensor to the left and pull it off. It has an o ring underneath be sure to not loose this, and the PCV valve is now in plain view. Pull it out with a pair of needle nose pliers. It also has an o ring wrapped around it. This should come out with the valve to be reused. =) there is not one even though the books call for a fram 299 pcv valve so dont worry bout it
The PCV valve on q 2007 Torrent is made into the valve cover. It is not removable, the valve cover and PCV valve must be replaced together.
