hi I wanted to ask a question, if with a scavange oil pump I create a vacuum in the crankcase what happens to the turbo oil drainage line?

thank you lorenzo

I generally recommend that the turbo oil drain is still returned back into the crankcase/sump as normal and then the scavenge stages pull oil from there. As far as the turbo oil drain is concerned, a vacuum is actually helpful to ensure oil drain back.
