The Steeda Focus ST Oil Separator for 2015-2018 2.0L/2.3L Ecoboost MK3 Ford Focus ST/RS reduces detonation, oil burning and deposits on the valves by removing oil drawn through the PCV system before it can contaminate the intake charge. This is also very helpful with these turbo applications, where it is essential to keep oil from entering the turbo.
Excess crankcase pressure (sometimes known as "blow-by") is vented from the crankcase through the PCV system, where it is drawn into the intake manifold and returned by the engine. This re-circulated air contains aerated oil from the crankcase which is burned by the engine.
