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). The 2010+ valve cover is plastic and cannot be used for this kit. The included -10AN male bung must be welded onto the valve cover at the location of the OEM crankcase vent fitting, as shown below. In order to utilize the included -10AN hose, a 2008-2009 Mitsubishi EVO X aluminum valve cover MUST be used. This kit is not a direct bolt-on and requires welding. The stock PCV valve is capped and not used (caps provided) in this kit. 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. However, some loosely built race engines operate with a large amount of boost pressure and the OEM hoses can become too restrictive for the excessive blow by. The closed system options listed above are adequate for most modified street vehicles. The 20-0181 Crankcase VTA Catch Can Kit is an open (vent to atmosphere) system used for high flowing, high horsepower applications. Laser cut powder coated LH mounting bracket Whats included in the 20-0106-08 and 20-0106-10 Crankcase Catch Can Kits: The cathc can kit will help collect the contaminants before they can get to the intake pipe. Oil coating the inside of the intercooler will lower the thermal efficiency of the intercooler and decrease performance. This can lead to oil collection in the intercooler. This draws unwanted crankcase vapors, unspent fuel, and oil sludge into the air filter intake pipe, turbocharger compressor, etc. When the engine is at high load (WOT), this hose will experience flow out of the engine and into the intake pipe.
If an aftermarket intake is installed, consider purchasing 20-0300 Alternate Location Mount separately. T hese aforementioned kits were designed with the OEM intake system. On 2010-2016 EVO X models which use the “plastic” valve cover, the hose is 1/2″ (13mm) and requires P/N 20-0106-10. 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. This is the hose that connects from the port on the valve cover to the turbo air intake pipe. The 20-0106-XX Crankcase Catch Can Kits (shown below) install immediately behind the LH headlight and plumbs in-line with the crankcase vent hose. Enough 3/8″ black PCV hose for custom applications Anodized aluminum hose ends and adapter fittings Laser cut powder coated RH mounting bracket Billet oil catch can with integrated condenser and dipstick
Whats included in the 20-0105 PCV Catch Can Kit: NOTE: Some European models have headlamp washer reservoirs which creates an interference with the PCV catch can. The PCV kit shown above is a closed system that requires a vacuum signal from the intake manifold to open the PCV valve. 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, no check valve required. The catch can acts as an in-line filter trapping and holding the contaminants before they can get to the intake manifold. When the PCV valve is open, unwanted crankcase vapor, unspent fuel, and oil sludge are drawn into the intake manifold. It installs immediately behind the RH headlight and plumbs in-line with the PCV hose. The 20-0105 PCV Catch Can Kit (shown below) is compatible with all 2008-2016 EVO X models. The Crankcase VTA kit does not recirculate crankcase gasses back through the engine and is intended for race vehicles dealing with a large amount of blow-by gasses. Furthermore, closed systems prevent unwanted oil vapors into the cabin. Closed loop systems route clean filtered air back in through the engine to be burned and to promote negative crankcase pressure for optimal performance. The first type do NOT vent to atmosphere (VTA), thus are emissions and track legal. Radium Engineering offers several completely independent oil catch can kits for the Evo X that are sold individually or together using the menu above. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance. 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.
