Where is the PCV valve located on a 2004 350z and is it easy to change?

The PCV Valve is located on the passenger side of the engine. Its next to cylinder #1 and looks like a black bolt with a hose on it. To remove, unhook the clamp on the hose, move it to the right, take the hose off the valve, unscrew the PCV valve and replace. New ones usually cost $11-$17. The whole process takes 5-10 minutes. It took me 45 minutes however because I dropped the old PCV valve inside the engine compartment, and the VQ setup is not pretty. So be very careful...
