thansk for asking me :fawk:
i have one and its inline the pcv hosing...
and i've been catching a good amount of oil into my can...
fro mthe debates i've been in.. its best to run the setup below:
valve cover crankcase to intake - place catch can inline)
pcv hosing -place catch can inline

another option people have done it have the catch can dumped into the atmosphere, because pcv stays shut when under pressure (turbo)
