Description
Radium Fluid Lock PCV Catch Can Kit - Ford Focus ST LW/LZ 11-18/Focus RS LZ 16-17
Application: Ford Focus ST (2013-2018) and Focus RS (2016-2018) EcoBoost
Part Type: Fluid Lock PCV-side oil catch can kit
Part Number: 20-0315-FL
Radium catch cans separate oil and water condensate from crankcase gases before they reach the intake, preventing oil build-up in the intake, intercooler, throttle body and intake manifold. It is a closed system, so oil vapours are kept out of the cabin.
On the PCV side, the can runs inline with the PCV valve and retains factory function. At idle, steady cruise and deceleration the PCV hose sees metered vacuum that can draw crankcase vapour and oil sludge into the intake manifold after a hard run – the catch can captures it first. Because Radium catch cans are pressure sealed, connection to the intake manifold is permitted on boosted applications. The kit mounts on the front LH core support near the radiator.

Optional Parts
- Radium Sound Symposer Delete kit - Ford Focus ST LW/LZ 11-18 (20-0356) – Required for Focus ST installations to provide clearance

Important Notes
- Focus ST installations require the Radium 20-0356 Sound Symposer Delete Kit or another symposer delete for clearance
- PCV side only – the PCV and CCV catch cans work independently and are also available together as dual kits (20-0328-FL Focus RS, 20-0358-FL Focus ST)
- There is no fixed emptying interval – check the dipstick from 3-4 weeks of driving, then as needed; PCV cans typically collect more than CCV cans
- Excessive oil collection can indicate an engine problem such as excessive blow-by or an overfilled oil level
- Empty by unscrewing the reservoir, or fit a Radium Petcock Drain Kit (sold separately) where there is space
- Installation instructions are available in the Instructions tab
