    The PCV system for this vehicle is quite simple. At each valve cover there is separate smaller cover called the breather cover. Connected to the breather cover is a rubber hose (one on the right breather cover and two on the left) each of these hoses connects to the air intake system at the rear of the motor below the air cleaner connection and the Mass Air Flow (MAF) sensor. You need to check to see that these hoses are all correctly connected and that the hoses are not cracked or collapsed. You will have to remove the air cleaner housing to get a good look at all the parts. You should also check and make sure the oil filler cap fits tightly and does not have oil leaking passed the seal. The PCV hoses I mentioned earlier are available at a reasonable price and should be in stock at any dealership. The sealer on the breather covers can leak oil (this is very common). Those are all the components to your PCV system. Good luck.
