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