An oil separator is provided for removing oil from crankcase ventilation gases of an internal combustion engine. The oil separator includes a housing and a spiral shaped wall. The housing includes an inlet and an outlet. The spiral wall defines a spiral path for guiding the ventilation gases between the inlet and outlet of the housing. The spiral path has a width that decreases at a predetermined constant rate between the inlet and outlet of the housing.
