OK, this car does not have a PVC valve. I went to the dealer and tried to buy one. The parts guy looked it up and couldn't find it. It does however have a crankcase vent valve, which is pretty much the same as a PVC valve.

It's located under the intake manifold on the drivers side. It's pretty much impossible to see, and is connected by two rubber hoses going to the engine. He had to remove the manifold to access it. All the rubber hoses were cracked and needed to be replaced. The ports where the hoses connected were completely clogged. He used a drill bit to ream them out by hand (very difficult to get-to).

The engine runs fine now and the oil problem has pretty much disappeared. A $20 valve solved it.
