    That is pretty slick. Lot of ingenuity went into thinking it up. And making it work right.

    I feel more confused. Should I just leave the 2 breathers on the driver vc and just clean it up every now and then again?

    Or add a breather to the passenger vc?

    My 2 cents, make everything as tight as possible, add 1 line to a small puke tank & you're done cheap.
    If you want to do it right, add something to actually remove the windage from the pan.
    Evac system, electric vac pump into a puke tank, or a belt drive pump.

    If I was running something that was actaully street able, I would run the elect vac pump off a diesel into a puke tank.
    No parasitic loss, and you gain a tiny tiny bit of HP without contaminating the charge.
