PCV VALVE is located UNDER the back of the intake on the valve cover. Follow the large vacuum hose from the intake manifold (not the one to the brake booster) to under the intake at the back of the engine. Better done when engine is cool asthe exhaust piping to the EGR is quite warm (frying eggs come to mind) when the engine has just been shut down. It's kinda tight in there so be careful of pinch points, etc. especially if you got BEAR PAWS for hands.
