I had the same problem, and after checking with the dealer twice, I finally found it. On the 3.8L engine, it is located under a sensor. Remove the plastic engine top cover (unscrew the oil cap and the cover easily pulls off). On the top left side (passenger) of the engine (just left of the top black center cover) is a sensor with with two wires (I think) that will twist off (half a turn to get it off). Twist off the sensor and the PCV valve is underneath.
