An oil separator that removes oil from ventilation gases flowing between a crankcase and an intake manifold of an internal combustion engine. The oil separator includes a housing, a wall and a diaphragm. The housing has an inlet and an outlet. The wall is cooperative with the housing to define a path through which the gases flow between the inlet and the outlet. The wall is movably coupled to the housing to effect a change in the height of the path. The diaphragm has a movable portion coupled to the wall. The diaphragm defines a substantially closed volume. The volume is open with the intake manifold so that pressure changes in the intake manifold causes corresponding displacement of the movable portion and the wall relative to the housing.
