I have a Cali 85 617 motor as well, without the separator. I burn no oil , at least not a detectable amount, in 4k oil changes. Yet, the two tubes, the one leading to the air filter, and the one going to the intake hose between the air filter and turbo inlet, get a little oil in them. I would imagine that maybe 1 tablespoon, but not much more, gets ingested into the intakebetween changes.
I remember reading that this trace amount of oil is good for upper cylinder wear prevention and valve lubrication and works like an oil mister. I wish the engineer who designed it this way would speak and resolve our questions.
Anyone know for sure?
Thanks, Adam Bush
