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.

EVO X CATCH CAN KIT DETAILS:

Radium Engineering offers several completely independent oil catch can kits for the Evo X that are sold individually or together using the menu above. The first type do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems route clean filtered air back in through the engine to be burned and to promote negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapours into the cabin. The Crankcase VTA kit does not re-circulate crankcase gasses back through the engine and is intended for race vehicles dealing with a large amount of blow-by gasses.

The PCV Catch Can Kit (shown below) is compatible with all 2008-up EVO X models. It installs immediately behind the RH headlight and plumbs in-line with the PCV hose. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience "metered" vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapour, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. Note: Because Radium catch cans are pressure sealed, they are great for boosted applications as well so connecting to the intake manifold is permitted and will withstand any boost level.





The PCV kit shown above is a closed system that requires a vacuum signal from the intake manifold to open the PCV valve.

The Crankcase Catch Can Kits (shown below) install immediately behind the LH headlight and plumbs in-line with the crankcase vent hose. This is the hose that connects from the port on the valve cover to the turbo air intake pipe. On 2008-2009 EVO X models which use the "metal" valve cover, the hose is 3/8" (10mm) and requires P/N 20-0106-08. On 2010+ EVO X models which use the "plastic" valve cover, the hose is 1/2" (13mm) and requires P/N 20-0106-10. During low engine loads, this hose experiences atmospheric pressure, but when the engine is at high load (WOT), this hose will experience vacuum and would normally be drawing unwanted crankcase vapours, unspent fuel, and oil sludge into the air filter intake pipe, turbocharger compressor, etc. For instance. if you are finding oil accumulation stuck in the intercooler, this catch can is a necessity. Oil coating the inside of the intercooler will lower the thermal efficiency of the intercooler.





The Crankcase VTA Catch Can Kit is an open (vent to atmosphere) system used for high flowing, high horsepower applications. The closed system options listed above are adequate for most vehicles, however, some loosely built race engines operate with a large amount of boost pressure and the OEM hoses can become too restrictive from excessive blow by. This VTA kit replaces the stock hoses and valve cover fitting with -10AN hose (5/8" ID) and allows the gasses to vent through the catch can to the atmosphere.



This kit is not a direct bolt-on and requires welding. In order to utilize the included -10AN hose, a 2008-2009 Mitsubishi EVO X aluminium valve cover MUST be used. The included -10AN male bung must be welded onto the valve cover at the location of the OEM crankcase vent fitting. The 2010+ valve cover is plastic and cannot be used for this kit. Like the EVO X crankcase systems above, this crankcase VTA kit mounts the catch can behind the LH headlight so there must be room for the included breather filter (shown above).
