An air-oil separator operating on an updraft principle for use with gasoline and diesel internal combustion engines. The separator includes a housing having an inlet and an outlet located at the upper end of the housing. Air-oil mixtures are introduced into the upper portion of the housing, flow downward with a vortex action, are deflected by a baffle at the bottom of the housing and reverse their flow to enter a conduit extending from the outlet and opening into the interior of the housing at a point near the baffle. The inlet has a smaller cross-sectional area than the outlet producing a reduction in pressure of the air-oil mixture. The reduction of pressure, vortex action, deflection and flow path reversal cause oil and contaminants in the stream to be deposited at the bottom of the housing where they are removed by means of a drain.
