    dang, nice job! you got it.

    it's not the condensate, although i don't want that going back through my engine either if i can help it... it's oil getting sucked right out of the oil pan, through the return line. it's happened before when the CCV freezes - it's an extreme scenario, but entirely possible. in short, the intake manifold pulls vacuum on the CCV, but the consendate in the lower half of the CCV is frozen (and thus blocking the outlet from the valve cover), so the oil from the pan comes right up the drain tube. clearly a gross oversight on BMW's part... the 1-way check valve would prevent destruction.

I ordered the CCV parts a couple of nights ago - it seems like this check valve is the last thing I need. Is it the 12mm that comes up by default when I click on the link?
    yep, it's that exact one! essentially it allows the oil and condensate to drain back into the oil pan - like the OEM design - but does not allow oil to come back up. it's a 1-way valve.

    I replaced my ccv two years ago with no change in consumption. Am I lucky/rare?

    Where did you place the order? Amazon was going to take forever to get it here. Napa or AutoZone don't carry it.
