Oil Catch Can Kit.
Oil Catch Cans have been around for a long time for racers and performance oriented guys. This unit is no exception to that rule, although you can use it on regular, unmodified street cars. The kit includes all you will need to install a functional, race-spec oil retrieval system. It is recommended that you run the unit with the optional breather port at the top plugged, but the kit does include a breather filter for reworked vacuum systems. The plug allows the intake to draw vacuum on the crank case and makes for a better running motor.
This unit may not be legal in some states for emissions and is intended for “off road use”. With that said… running this system may help emissions by catching extra blow by in the can.
