replace the intake side PCV valve with a mkiv one if you haven't done so already.. Then, do not worry about that side of the motor after doing so.
move on to the exhaust side (twins) and place hose running from the valve cover vent to the catch can itself (ex. mine is placed behind the passenger side headlight). From there, run another hose out of the catch can to the suction port on the turbo intake piping. the two ports are within about 7" of each other, just follow the hoses below.
