The Damond Motorsports Oil Catch Can kits come with everything needed for an optimized Oil Catch Can system. An oil catch can is, in a sense, a filter for the positive crankcase ventilation system. The oil catch can(OCC for short) is used to tap and contain blow-by oils and condensed crankcase gases, that would otherwise flow throughout the PCV system back into the intake tract, and allows for draining of these fluids remotely. With the addition of an OCC kit, blow-by oils and gasses are routed to the OCC, allowing them to be captured. This prevents the blow-by from entering the intake system, where it would otherwise contaminate the clean air entering the engine. Cleaner air leads to better combustion, more power, better fuel economy, less detonation, and less oily build-up on the valves. 

What sets the Damond Motorsports OCC kits apart from the rest, is that we fully test our OCC components, to insure the best OCC set-up for your vehicle. Only high quality components are used in the Damond Motorsports OCC kits. Our OCC kits come tailored to fit your GR Corolla perfectly, for a no-hassle, quick and simple installation. 

The DM OCC kit connects into the valve cover PCV/above engine induction tube hose connection. Oily blow-by contaminates travel this path during boost, as the intake is intended to pull a slight vacuum as air travels past the PCV port. This causes a fine oily mist that would otherwise flow into the intake, turbo, and eventually intercooler and piping. With the DM OCC kit in place, the hoses route the blow-by to the OCC, where they can be filtered and cleaner air is sent back into the intake. In turn the primary benefits are: cleaner air mixture, and less oily build-up on the valves and in the intake manifold. 

Included in each Damond Motorsports GRC OCC kit:
-A Damond Motorsports OCC fully assembled
-Hose splicer connectors to connect to the OEM hose as well as aftermarket hoses
-Oil and vacuum resistant hoses
-Location specific bracket, and mounting hardware 
-Slim stainless steel hose clamps
-Zip ties to keep the hoses at bay
-Drain barb and hose included


The DM Billet OCC features:
-NEW Billet design, allowing for greater serviceability and modularity.  
-Layers and layers and layers of perforated baffle plates, allowing a large surface area for blow-by vapors to latch onto and keep the intake tract clean. The bottom layer features an oil scraper. Blow-by is forced directly onto the scraper, while the air is pushed around the sides of the can to the back of the lower chamber. The air is then drawn up diagonally through 3 more perforated plates, before it exits the top chamber. 
-A super easy to use high flowing drain valve.
-The OCC assembly features viton o-rings, for superior oil & fuel compatibility.
-The hose barb ports are a -8 ORB, allowing for various fittings.
-Anodized black for enhanced durability.
