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. This catch can runs inline with the PCV (positive crankcase ventilation) valve and retains it's factory function. For clearance purposes, Focus ST owners will need the Radium sound symposer delete kit. The 20-0315 PCV Catch Can Kit, Ford Focus is used in both the ST and RS models with the EcoBoost engine. No cutting, drilling or permanent modification to the vehicle is required. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin.

A closed loop system also promotes negative crankcase pressure for optimal performance. Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. They do NOT vent to atmosphere (VTA), thus are emissions and track legal.

These two oil catch cans (PCV side and Crankcase side) function completely independent of each other and are sold individually or together. The catch cans mount using factory holes and integrate perfectly with the surrounding components. The Radium Engineering catch cans are the most functional and integrated kits on the market. 2013+ Focus EcoBoost Catch Can Kit Details:
