A crankcase breather oil collector serves to capture oil vapor mixed with crankcase blowby gases, and contain the oil vapor to preclude its exiting to the atmosphere and/or collecting on external machinery components. The device basically comprises a canister which communicates with the crankcase of a four stroke reciprocating internal combustion engine by a tube or line. Blowby gases and oil vapor mixed therewith are routed to the canister by the tube or line, with the oil vapor cooling and falling out of suspension with the blowby gases to condense and collect as a liquid in the bottom of the canister. The blowby gases then exit the canister through a filtered vent or outlet. The outlet filter serves to preclude significant particulate matter from being expelled to the ambient atmosphere, and also serves to protect the engine by precluding the entrance of airborne contaminants to the engine when the engine is shut down and cools to provide a relatively low pressure within the crankcase. The oil collected within the canister may be drained by a petcock or drain valve for periodic proper disposal as required. While the present oil collector may be adapted to virtually any type of four stroke reciprocating internal combustion engine not having a positive crankcase ventilation system, it is particularly well suited for use with motorcycles, which are not required to have any form of emissions controls thereon.
