Product Details

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 Fiesta ST perfectly, for a no-hassle, quick and simple instillation. We utilize the same quick connectors Ford uses, to ensure a factory-tight seal, as well as an easy install. All the fittings and hoses are pre-assembled on our end, so there's less work for you..

Every DM OCC kit includes a check valve(at no additional cost), to prevent boost from possibly entering the crankcase, via the prone to leaking OEM PCV valve. The check valve allows for a 1-way operation of the OCC system, keeping everything under vacuum, to better help vent the crankcase, and keep unwanted pressure and blow-by from exiting the valve cover port.
The DM Fiesta ST OCC kit connects into the intake manifold/valve cover PCV connection. Most oily blow-by contaminates travel this path from boost into vacuum transitions, where crankcase pressure has the potential to be greater, then the system immediately turns to a slight vacuum. This causes a fine oily mist that would otherwise flow into the intake manifold. 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 manifold. In turn the primary benefits are: cleaner air mixture, and less oily build-up on the valves and in the intake manifold.  

Thanks to the feedback and support from our customers, we now have hose sleeving available for the Fiesta ST OCC kit. The sleeves are a nylon braid, intended to protect the hoses from rubbing against other components. While the hoses included in our kits feature multiple layers, these sleeves offer extra peace of mind to prevent the outer layers of the hoses from rubbing in this tight engine bay. Available now for only $10. 

Included in each Damond Motorsports OCC kit:
-A Damond Motorsports OCC 
-OEM quick-connect hose connectors
-Quick-opening/high-flowing check valve, assembled/sealed with fittings
-Pre-cut oil and vacuum resistant hoses, fully assembled with fittings (black, blue, or red)
-Location specific bracket, and mounting hardware to mount the OCC 
-Slim stainless steel hose clamps
-Zip ties to keep the hoses at bay
-Drain barb and hose included
-optional nylon hose sleeves


The DM OCC features:
-Fully welded external aluminum structure. Welded on ports for a nice clean look, and to keep weight at a minimum. 
-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. 
-Powder coated for enhanced durability.

Perfect addition!

I could not ask for a better quality product, along with a slick look, you can’t get any better than this.


Very well constructed and thought-out. Installation took less than half an hour. The online instructions are easy to follow. Being able to install this without cutting into the stock lines is a huge plus, as is the tidy install location. The can itself is sturdy and high-quality, and I have no concerns about the durability of the mounting. Routing the hoses and drain line was the most difficult part of installation. Remains to be seen how effective this OCC is, but I am confident I'll be satisfied within an OCI or two.

Amazing Product!

Being a proud Fiesta ST owner (like you reading this) makes me feel pride for my little pocket rocket therefore I consistently look for options and products that will make my car efficient, secure, and - above all - give it a little bit more oomph. This product surely fits the bill when it comes to my sanity and state of mind, given that I can sleep at night knowing those blow-by gasses are a thing of the past. Installation was simple, thorough, and even fun!!!! I highly recommend it for all those Fiesta ST owners who want nothing but the best for their cars in terms of reliability, efficiency, and performance and are truly passionate about their very own pocket rockets.

Well designed product

Installation was mostly straightforward. I had a strut brace which made things a bit more difficult. Just be aware.
Seems like a high quality item.

Fiesta OCC

Typical Damond experience. I spoke with the owner via Facebook to get details, then ordered online. Quality and fit of the can are outstanding, as is the customer service. I had a couple of questions about the install which were promptly answered and he even sent me a small gift for being a repeat customer.
