    Jlt oil separator issue

    Installed JLT oil separators recently on both passenger and driver sides. Passenger side fills within 1000 miles and the drivers side is bone dry. Why would the passenger side fill so quickly with nothing in the drivers side? Seems like the drivers side valve cover is not venting at all. Any ideas?

    I installed a breather on the driver side VC, and plumbed in a Moroso catch can into the passenger side back returned to the blower PCV line. Used a kit that uses the oil fill tube as the suction point

    The PCV system is a loop. Fresh filtered air is introduced to the crankcase through the driver side cam cover. There is a vacuum behind the throttle body caused by the engine running, so the connected port in passenger side cam cover is tied to said vacuum of the plenum.

    Think of it like this: Your Driver side cam cover is the PCV system's intake, and the passenger side is the exhaust. You should never see oil in the driver side PCV tube. If you do, you have other issues. The passenger side is the one that will collect all the oil.

    Yes a separator on the driver side is unnecessary. Sell that thing and get some of your money back haha.
