you need the turbo oil-drain free flowing - the stuff coming out of the housing is a very hot, oily, frothy, shit that HAS to see crank-case atmosphere not a liquid 'wall', otherwise it'll rapidly pressurise the turbo bearing housing resulting in failed bearings/seals and a smoke trail like a VL-single-legger.
