ABSTRACT:
A separator receives crankcase fumes having blowby gas and oil mist. A rotatable filter in the separator passes the gas constituents to an outlet for recycling back to an engine air intake. The filter, by rotating, causes oil to be flung centrifugally out onto a wall from which it can be drained from the separator and returned to the crankcase.
