The Mazda 3 Turbo Oil Catch Can kit helps remove water and fuel vapor from the engine crankcase keeping these contaminants out of the engine oil. While the SkyActiv engines have a factory air/oil separator before the PCV, it does a poor job at preventing contaminants from entering your intake manifold, gumming up your intake valves, and causing poor combustion. If you want to keep the Mazda 3 SkyActiv engine in your new Mazda healthy, a Catch Can system is required to keep contaminants from entering your engine.

Designed for both Mazda OEM and CorkSport Upgraded Turbo Inlet Pipe systems.

The CorkSport Advantage

Engine Health Focused:

The CorkSport Oil Catch Can receives input from the PCV valve and the valve cover breather/intake manifold. These two sources typically send oil, fuel, and water vapors from inside your engine’s crankcase back into the combustion chamber, causing less than optimal combustion and over time dirty intake valves. The CS Oil Catch Can capture these vapors and condense them in the catch can before the air is ingested by the engine.

Performance Design:

The CS OCC is a dual chamber design that uses a built-in baffle to separate the inlet and outlet ports. The inlet is tangent to the inside edge of the OCC, which promotes the spinning/swirling of the incoming vapors and contaminants and causes them to condense on the walls of the OCC and settle to the bottom for drainage. The clean air then travels through the center of the baffle and out of the catch can.

See the Difference:

Oil catch cans are especially important on turbocharged and/or direct injected vehicles to ensure long-term engine health, even more so if your vehicle is modified. While there is a factory air/oil separator, we have found that it does not perform at a high level. Check out all the contaminants our OCC caught on our Mazda 6 2.5T during the first 3000 miles after installation. Typically, all of this would have entered your engine which over time adversely affects engine health.

Optimized Fitment:

The CorkSport OCC kit was designed specifically to fit the vehicles equipped with the SkyActiv 2.5L (both Turbo and Non-turbo engines). Not only was the stainless bracket designed specifically for these Mazda chassis, but it is also in a location chosen to be easy to access and empty during an oil change. Plus, the location in front of the driver’s side wheel ensures short routing for all OCC lines. This means an easier install and less distance for contaminants to travel before being trapped in the OCC.

Materials and Manufacturing:

The CS oil catch can dipstick, ports, and end caps are precision machined out of 6061-T6 billet aluminum, while the body is constructed of cast aluminum. Each part is then coated black for corrosion resistance and a classy look. The supplied mounting bracket is laser cut and precision formed 304 stainless steel; again for superior corrosion resistance. Finally, the supplied OCC hoses are made from reinforced silicone for great resistance to heat, oil, fuel, and the elements so your catch can set up lasts as long as your Mazda!

If you live in an area that gets below freezing, you must empty the catch can before temperatures drop to maintain proper functionality
Removal of the OEM valve cover breather hose and PCV hose on Turbocharged models is quite difficult. Read through the instructions below if you are concerned
Replacing the OEM PCV system with an aftermarket Oil Catch Can System may allow smells of gasoline and oil to ventilate into the engine bay and thus the cabin depending on HVAC settings; this is normal of an Oil Catch Can System especially during idling situations and after shutting off the engine. If excessive smell is noticed, inspect hose connections and drain the catch can.
Recommended to inspect & verify the PCV is working correctly when installing the OCC Kit. Replace if needed.

I just installed the Corksport Oil catch can just two days ago. I did this as a preliminary safety feature before installing my VT supercharger.

The install was very straightforward and easy. The CS instructions are really good. The only thigs I noticed is that the initial angle recommended for the attachment of the catch can to the bracket didn't work for me and I had to change then angle, which is super easy as there are various holes on the catch can. I may have read the instructions wrong also at the beginning. Other things were, the shifter cable they they you to route around had a different orientation on mine, but this made pretty much no difference. I also didn't remove the two 12mm that attaches the electrical harness for the starters' bracket to the transmission. I didn't need to. I also did not install the brass fitting to the bottom of the drain. I plan to to drain it straight down rather than attach a hose to it.

Really no problems at all, with the install.

Initially I definitely experienced a decrease in low end power, I checked the hoses, they are all fit snugly so I don't think there is a vacuum leak. I am attributing the initial power decrease to the Mazda Sauce Tune reset after the battery was disconnected, so it took a while for it to adapt back to the higher octane E20. That's what I am attributing it to.

All in all it was a satisfying install and should be slightly better for the cleanliness of the twin-screw supercharger that I am going to add after getting it ported.
