The PCV valve is located behind the alternator, under the intake manifold. The best way I found to get to it is to remove the Passenger front tire, remove the splash guard, Remove the bolts on the Power Steering hose bracket (just makies it easier to get into the area),remove the oil filter. You should be able to see a hose that runs parallel to the engine block behind and above the alternator. I had to grab it with a plier to get enough leverage to pull it out. Once out, I was able to remove the hose and replace the valve. I put a little oil on the valve exterier to make it slide in easier.
