This air / oil separator with oil return from Radium Engineering is very much like an oil catch tank however this kit is designed to return the excess oil back to the engine sump so it is a service free system making it ideal for engines which omit large amounts of oil vapour in the breather system. The tank includes a heater to eliminate water vapour ensuring contaminated oil is not introduced into the engine.Provides service free oil separation from the engines breather systemReturns separated oil back to the engine sumpIncludes a heater to remove water vapourPrevents oil contamination build up on the engines intake systemImproves engine performance and lowers emissionsRadium Engineering air oil separator tanks feature a baffle system and a stainless steel filter which allows oil vapour to condense and drop out of suspension. The separated oil is then kept in the tank allowing clean air to vent back into the engines intake. The catch tank is designed to be free flowing so as not to c
