RADIUMAUTO catch tank kit for Ford Focus EcoBoost

A catch tank is essential on a high-performance vehicle to protect the engine from increased blow-by from the crankcase that accumulates when driving at high power. Excess oil-saturated air flowing back into the intake stream can result in poor performance.

Focus EcoBoost catch tank kit details
Radium Engineering's catch tanks feature large 10AN-ORB ports, a 4AN-ORB drain port, a 2-stage oil separator and an O-ring sealed dipstick. These kits mount over the factory holes and blend perfectly with the surrounding components. These two oil catch tanks (PCV and CCV) operate completely independently and are sold individually or together. They do NOT vent to the atmosphere (VTA) and are therefore suitable for exhaust and railway use. Closed-loop systems remove oil and sludge from the PCV exhaust before it is sent to the engine for combustion. A closed-loop system also promotes crankcase vacuum for optimal performance. In addition, closed systems prevent unwanted oil vapors from entering the interior. The built-in dipsticks in the collection tanks allow easy inspection of the accumulated liquid. No cutting, drilling or permanent modifications to the vehicle are required.

20-0315-FL Compatibility:
16-18 FocusRS
13-18 Focus ST

This kit is used in both Ford Focus ST and RS models with the turbocharged EcoBoost engine. It mounts on the front left core support near the radiator.
For release reasons, Focus ST installations REQUIRE Radium 20-0356 Sound Symposer Delete Kit or other symposer delete kit to be installed.

This catch tank runs in-line with the PCV (positive crankcase ventilation) valve and retains its factory function. When the pressure in the intake manifold is near or greater than atmospheric pressure, the PCV check valve closes, preventing flow through this hose. Conversely, a "metered" vacuum is created in the PCV hose when the engine is idling, cruising, and braking. This normally draws unwanted crankcase fumes, unused fuel and oil sludge into the intake manifold immediately after a high load run. Note: Because the Radium Catch Tanks are pressure tight, they are excellent for this application with boost pressure, allowing porting to the intake manifold.
The exact contents of the 20-0315-FL kit can be seen in the photo below:

These catch tank kits mount to the rear left side of the engine compartment.

This catch tank runs inline with the crankcase ventilation port. At light loads it is at atmospheric pressure, but when the engine is running at high loads (WOT) this hose will experience high flow from the crankcase. This would normally result in a build up of oil and sludge in the air cleaner intake pipe. Oil accumulates in the charge air cooler, reducing the thermal efficiencies of the heat exchanger and resulting in performance degradation. The exact contents of 20-0316 can be seen in the photo below (similar to 20-0357-FL).

Each set contains the following :
-Anodized catch tank with integrated condenser and dipstick
-Anodized laser cut Focus specific mounting bracket
-Anodized aluminum -AN adapter fittings and hose ends
-Enough PCV tubing for custom applications
-Stainless steel mounting hardware

Both of the above catch tank kits (PCV and crankcase) can be purchased together with part numbers 20-0328-FL (Focus RS) or 20-0358-FL (Focus ST).
