JBR Focus ST Oil Catch Can Stage 2 Black - FOCI-ST-OCC-S2
Full Product Description
During everyday engine operation, blow-by gases, as well as oil mist from the engines rotating components pass through the PCV valve and are routed back into the intake for the engine to burn off. However, some of that oil mist and other contaminates adhere to the intake and the valves. Over time a crust is formed reducing performance and potentially leading to a costly cleaning or repair. This is especially a problem for 2.0L Ford DI motor where there's no fuel passing over the valves to clean them. This is why an OCC is a must have for the Focus ST community.
Part # FOCI-ST-OCC-S2
Lids Press-Formed from 304 stainless
Inlet & outlet fittings fabricated from straight 5/8" 304 stainless tubing
Can fabricated from 304 stainless and CNC machined components
Precision TIG welding on all components
Internal filters machined from 6061 perforated aluminum
1/4" NPT quick drain
As PCV gases enter the catch can they disperse and flow through a series of four filter screens. As the gases flow through the screens, heavy oil and gunk sticks and lighter gases reach the outlet tube at the top. Accumulated oil and gunk naturally run off the filter screens and collect at the bottom of the tank. Throughout the life of the catch can, the filter media will never break down or need to be replaced like catch cans with mesh filter material. The net effect is blow-by gases, oil and other impurities do not have a chance to reach critical components of your engine.
So what’s wrong with the factory PCV valve?
The short answer is… nothing; as long as the car is stock and everything is properly maintained. But if you are running anything more than stock boost or would prefer to not have oily residue in your intake and crud building up on your valves, read on.
Since the PCV valve is the heart of the PCV system, let’s start there. This thing is notorious for not being able to completely close to prevent boost from entering the crankcase, even when brand new. Add a few thousand miles worth of crud flowing back and forth through it and the worse it gets. And, the more boost you run, the greater the problem becomes.
The check valve included with the stage 2 OCC kit is designed to be closed 100% of the time unless vacuum is present. This check valve is oil, fuel and chemical resistant. It's constructed from solid brass, it has an incredibly low crack pressure and it's the largest check valve available so that normal flow isn’t impeded.
Unfortunately the OEM check valve just can't close instantly under boost and therefore crankcase pressure and turbo spool times are increased. For higher boosting cars or those seeking the best possible performance out of their engine an OCC check valve is a must.
