Radium PCV & Crank Case Dual Oil Catch Can for 2012+ Scion FR-S/Subaru BRZ [ZN6/ZC6]
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.
These two oil catch can kits are completely independent of each other and are sold individually or together. They 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 vapors into the cabin.
FR-S / BRZ / 86 MOUNTING LOCATION
The ""Crankcase Vent"" kit mounts on the left side of the engine bay.
This catch can runs inline with the 1/2"" breather port. At low loads it experiences atmospheric pressure, but when the engine is at high load (WOT), this hose will experience vacuum and would normally be drawing unwanted crankcase vapors, unspent fuel, and oil sludge into the air filter intake pipe. If the engine is turbocharged or supercharged and you are finding oil accumulation stuck in the intercooler, this catch can is a necessity as oil will lower the thermal efficiency properties of the heat exchange process.
The ""PCV Valve"" kit mounts on the right side of the engine bay.
This catch can runs inline with the 3/8"" PCV (positive crankcase ventilation) valve. 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 vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. Note: Because the Radium catch cans are pressure sealed, they are great for boosted applications as well so connecting to the intake manifold is permitted.
Petcock Drain Option
This kit, sold seperately, can be used to remotely drain the catch cans without the need to unscrew the canister body.
