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 2.3L DISI motor where there's no fuel passing over the valves to clean them. This is why an OCC is a must have for the Mazda 2.3L DISI community.

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.
