Hey Jeff==It is on the pass side of the intake manifold. There should be a hose going from it to the throtle body. GoodluckJoe

Additionally: I rotated my engine to get access to the pcv, and changed the three sparkplugs back there while I had access. Using the slope of the driveway as a helper, I was able to swing the engine just by grabbing the top and pulling it toward me. Jonny
