A closed crankcase ventilation system for an internal combustion engine is disclosed. A compressor is configured to compress air and enhance the venting of crankcase emissions from a crankcase of the engine. A flow path is provided between the crankcase and an intake of the compressor. A prioritizing device is situated in the flow path and configured to regulate the flow of crankcase emissions and control pressure within the crankcase. A treatment element is provided downstream of the compressor and configured to treat the compressed air and crankcase emissions to remove entrained oil. A first conduit downstream of the treatment element is configured to introduce a first portion of the compressed air and crankcase emissions into one of an exhaust system for the engine and an air intake system for the engine. A second conduit downstream of the treatment element is configured to introduce a second portion of the air and crankcase emissions into a system having at least one component utilizing compressed air for its operation.
