Thanks hattee,
I was about to post my findings here for future reference. You are correct, the PCV valve is located at the end of the black S-shaped hose. It is (facing the back of the car) about 6 inches to the right of the oil filler cap on top of the engine under the cover labled "16 valve DOHC". Pair of pliers for hose detachment and a 14mm wrench worked wonders. 15 minute job tops!
