I'm assuming you have the 2.0? Have you called the dealership to make sure you don't qualify for the recall, they were all replaced at one point, including a metal hose to the turbo as well.

If you don't qualify, then it is just a matter of unscrewing the 6 T25 Torx screws from the PCV valve on the front of the valve cover, disconnecting the two hoses, and replacing it.

Expert:  gomi_otaku replied 1 year ago.

Are you able to remove the oil cap with the engine running, or does it suck down really hard? That is the symptom of the PCV being bad.

I have a 2.5 engine is it the same has 2.0
Expert:  gomi_otaku replied 1 year ago.

No, on the 2.5 the problem is usually internal in the valve cover- as the PCV system is built into it.
