put the pcv on the side opposite the fill cap.make sure there is suction at the pcv, else find out why. make sure the vlave cover is tight.

to check the pcv system, let the car idle with pcv in VC. remove breather and hold a stiff piece of paper up against the grommet. it should be sucked up against it (albeit lightly). if it doesnt, you dont have enough vacuum or too much blowby or the oil fil or VC is leaky
