Yes Rollin it is and remember Every K over is a KILLER! woot.Rollin said:there should be a line from the rocker cover to the can (on the side near the top usually) then a line from the top of the can to the intake (before the boosting apparatus) and another from the bottom of the can back to the sump (?)
oil/air comes in from the rocker cover, gets seperated in the can (i think they have a filter or some steel wool or something in them to help this process?) the oil drains into the sump, and the air goes into the air intake to be burned by the engine.
i have seen lots of imports with the can vented to atmosphere, instead of back into the intake, which is illegal *tisk tisk tisk*
