The pipe from the air filter to the valve cover is the fresh air source. I
doubt there is an oil/air separator under
the valve cover; a baffle maybe--like in a Healey valve cover--but I haven't
had the valve covers off.
From:
http://en.wikipedia.org/wiki/Crankcase_ventilation_system
about halfway down: "It is an "open system" in that fresh exterior air is
continuously used to flush contaminants from
the crankcase and into the combustion chamber."
