Pcv System Ok so i replaced my pcv system and was wondering if the air is pulled from the driverside valve cover or from the passenger side valve cover? anyone got a flow chart? i think i may have my pcv valve on the wrong way.

on the ls1 fbody engine
fresh metered air starts on the top, passenger side of the throttle body. a hose runs from there to the front of the passenger side valve cover (metal fitting faces forward).
the "pull" side of the system starts on the lower passenger side of the intake manifold snout. a hose runs from there into the PCV valve (about 3" from the manifold port). it then runs back along the top side of the valve cover and around the rear of the engine. there is a Y fitting that has one side running BACK towards the passenger side valvecover, and connects to the pcv fitting on the rear of the passenger cover (fitting faces backwards). the other side of the Y runs behind the engine to the plug on the very back side of the driver's valve cover. its more of a plug than a fitting.
hope that helps.
