An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from high performance driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance.
 
2013+ Focus EcoBoost Catch Can Kit Details:
Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick. These kits mount using factory holes and integrate perfectly with the surrounding components. These two oil catch cans (PCV side and Crankcase side) function 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 remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. No cutting, drilling or permanent modification to the vehicle is required.
 
 
PCV Side Catch Can Kit (p/n 20-0315):
This kit is used in both the Ford Focus ST and RS models with the turbocharged EcoBoost engine. It mounts on the front left core support near the radiator.
For clearance purposes, Focus ST installations REQUIRES Radium 20-0356 Sound Symposer Delete Kit or other symposer delete kit to be installed.
 
This catch can runs inline with the PCV (positive crankcase ventilation) valve and retains it's factory function. 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 this boosted application so intake manifold connection is permitted.
 
Crankcase Vent Side Catch Can Kit (P/N 20-0316 and 20-0357)
This catch can kit mounts on the back LH side of the engine bay. The Focus RS requires kit 20-0316, while the Focus ST requires kit 20-0357. This is due to different mounting bracket designs necessary because of the subtle changes between the engine bays. 
For clearance purposes, Focus ST installations REQUIRES Radium 20-0356 Sound Symposer Delete Kit or other symposer delete kit to be installed.
 
Each kit includes the following: 
-Anodized oil catch can with integrated condenser and dipstick
-Anodized laser cut Focus specific mounting bracket
-Anodized aluminum -AN adapter fittings and hose ends
-Enough PCV hose for custom applications  
-Stainless steel mounting hardware 
 
 
PETCOCK DRAIN KIT OPTION
-4AN ORB to barb fitting 
-Nylon ¼” barb ball valve 
-PCV Compliant Rubber Hose
This kit can be used to remotely drain the catch cans without the need to unscrew the canister body. One kit per catch can. Radium recommends this kit for the PCV side catch can, as this is the side that will see the most oil accumulation.
