What is the pc valve and is it easy to change

 

You got me? Maybe its called something else?

 

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.

 

is yours bad..........it should not need changed for several years...........

 

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.........
