ABSTRACT:
An oil/air separator (10) condenses and collects oil vapors carried by blow-by gases from the crankcase of an internal combustion engine. The oil/air separator comprises an inlet vent (17), an outlet vent (56), a first filter means (32), a second filter means (34), a third filter means (44), an oil collection chamber (28), an excess oil return line (64), and a drain plug (61). The integrity of the combustion chamber in preventing air/fuel vapors and exhaust gases from passing into the crankcase can be determined by the amount of accumulated oil (62) in the collection chamber.
