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. 




  • 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
  • 6fl Oz Capacity
  • Height (without fittings): 5 inches
  • Outside Diameter: 2.45 inches
  • Radium billet oil catch can with integrated condenser and dipstick
  • Radium laser cut powder coated ""86"" specific mounting bracket
  • Anodized aluminum -8AN hose ends and adapter fitting
  • Enough 1/2"" PCV rubber hose to mate to custom applications
  • Barb hose adapter
  • Stainless steel mounting hardware

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.

Radium engineers have strategically located the catch cans for compatibility with both Right Hand Drive (RHD) and Left Hand Drive (LHD) ""86"" model variations. Some brake clearancing is necessary on RHD installations. Both of these kits are also compatible with all current aftermarket forced induction kits. Mounting is done using factory holes. No cutting, drilling or permanent modification to the vehicle is required.

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.



Gasses enter the catch can through the top port and immediately pass through a stack of stainless steel condenser media. This provides surface area for the hot oil vapor to cool and condense. This creates a phase change within the oil makeup converting it from a vapor to a liquid. All of the liquid oil collects and drips down to the bottom of the canister. Remaining gasses continue through the catch can chamber where they slow down allowing time for more oil vapor to condense on the interior surface walls. Then ""clean"" gasses exit through the front port and back into the engine's intake stream.

Petcock Drain Option

  • Anodized -4AN O-ring barbed fitting 

  • Nylon ¼” barb mini ball valve 

  • 6ft high temperature rated 1/4"" rubber hose

This kit, sold seperately, can be used to remotely drain the catch cans without the need to unscrew the canister body.
