Abstract:
A one-piece combination oil fill/air breather cap for an automotive type engine positive crankcase ventilation (PCV) system that includes a filter and oil separator chambers below the filter defined by partitions or baffles upon which the oil droplets impinge during reverse flow operation of the PCV system; a double lip flared annular seal operating in tension being sandwiched between the cap lower surface and the engine rocker arm cover to minimize oil leakage.
