Having an oil catch can is essential on a performance vehicle. It is used to protect the engine from elevated levels of crankcase blow-by that can accumulate from aggressive driving on and off the race track. Without an oil catch can the engine is prone to having excess oil saturated air circulating back into the air intake stream which can lead to degraded performance. Some vehicles may require multiple catch cans depending on the design of their engine's PCV system.
Installing a dual catch can setup will give you the ability to convert a modern closed PCV system to an open PCV system, it is not recomended for applications that do not demand it as the crankcase will not measure any negative pressure and will no longer be smog legal. Having an open PCV system on vehicles that it is called for will eliminate any chance of oil vaoprs returning into the intake air stream and causing a build up. The Radium Engineering dual catch can kit would be a good unit to use for a track spec car using a turbo without a compressor inlet pipe.
Unlike many catch cans on the market, Radium Engineering’s 6061 Billet Aluminum O-Ring Sealed Oil Catch Can is designed with an integrated oil separator that accelerates oil condensation and is completely cleanable and reusable. The liquid oil is collected in the reservoir and can be easily disposed without removing the can from its Laser cut and powder coated mounting bracket. The lower half of the oil catch can body unscrews with ease for draining or a Radium PETCOCK drain Kit can be installed if the cans cannot be easily separated due to space. Excessive oil collection can be an indicator of a damaged engine, Radium integrated an easy-to-use 6061 Billet Aluminum dip stick for the convenience of checking the oil levels periodically.
