RADIUM Universal Dual Catch Can Kit


An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance. Unlike many catch cans on the market, this catch can features an integrated oil separator that accelerates oil condensation. This stainless steel filter media is cleanable and reusable.


The liquid oil is then collected in the reservoir. The fluid can be easily disposed without removing the can from its bracket. The lower half of the body simply unscrews for draining or the bottom port can be used with the RADIUM Petcock Drain Kit if the cans cannot be easily separated. The integrated dip stick unscrews for a quick way to check oil level.


-Effectively raises the octane and increased engine performance from cleaner inlet air 
-Prevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc. 
-Excessive oil collection can be an indicator of a damaged engine. -Lowers hydrocarbon emissions

Adapter Fittings Below are a just a few of the optional fittings for both inlets and outlets of the catch cans.  

Use this guide to select the propoer hose barb fitting:

Radium also has low profile 90 degree swiveling adapters for tight locations (shown below).


Below is an example of the 2-piece 90 degree adapters. The 1/2" (-8AN) and 3/8" (-6AN) push-lok fittings are shown.


Open PCV System This option is used to convert a modern closed PCV system to an open PCV system. Radium Engineering does not necessarily condone an open PCV system, however, there are many applications that demand this setup.

Includes: -Black Anodized Aluminum Barb Fitting with O-Ring -Green Crankcase Air Filter -Worm Drive Hose Clamp

Open PCV System Disadvantages: Without an intake return for the PCV system, the crankcase will not measure any amount of negative pressure that can be, argueably, beneficial for the piston rings. Over time, a light mist of oil vapor will accumulate around the engine bay near the crankcase breather. An open PCV system is not smog legal and will not pass a visual emissions check.

Open PCV System Advantages: Completely eliminates any chance of oil vapor returning into the intake air stream and collecting in idle air control valves, intercoolers, etc. Required for specific applications. For example, a race car using a turbocharger system without a compressor inlet pipe.

Some vehicles may require multiple catch cans depending on the engine PCV system design.
