Its a PCV valve. On our cars i dont know where its located. On my old car which is a Regal, it sits right on the valve cover. How many miles on your Tc?

ya why would you already have to chance the pcv valve?

If I remember right it has to do with the oil not flowing backwards from the airfilter into the engine.

On the Xb and XA we do not have a PVC "valve"

It is the 3/4 inch tube that comes out of the top of the head and runs to the air intake tube to the air box. on an after market intake they supply a PVC type valve that you attach in the middle of the head to the intake on a hose supplied in the kit.

Sorry could not find a pic of the TC motor to see where it would be.

These rarely go bad in cars that have PCV "valves"

i have no idea. the guy from the service dept said it needed to be changed. i only have 31k on my car

pretty sure it is the tube from the back side of the valve cover.....onthe passenger side........not 100% sure though.........
