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.

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

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.





Price is $190, free US shipping

A little info about the available add-on VTA kit.

The Damond Motorsports VTA kit, can be added to any DM Oil Catch Can. It consists of a one-way check valve and high quality filter, which allows for pressure in the crankcase or OCC system to vent.

Since our standard OCC kits for the Fiesta ST come with a check valve, the check valve will prevent boost from entering the OCC. This allows us to run another valve with a filter on the OCC itself, to vent any excess crankcase pressure in the system, without a vacuum or boost leak. We generally recommend the VTA kit on higher boosted/tuned FiST's, where excess crankcase pressure may be present. When the pressure in the crankcase is higher than the vacuum pull from the upper intake pipe under boost, it can lead to a reduction in power(very minor, but that pressure is pushing up on the piston as it goes down in the crankcase), oil seals leaking, or the dipstick popping.

The VTA kits, can be added on to your OCC kit when placing an order for only $25, or $30(free US shipping) if purchased separately.

As the only manufacturer of a OCC for the FiST that has a VTA option, can you speak to its merits?

Obviously going VTA ensures that no blow by can get to the IM, but this also removes the source of vacuum on the crank case when not under load. From my (albeit limited) knowledge, keeping some negative pressure in the crankcase is generally desirable. What say you?

Think of it more as a "partial VTA," there's a 1 way valve concealed under the filter, where it will only vent when there is pressure in the system, and that would only come from one source... the crankcase. This is due to the kit containing a check valve on the intake manifold to OCC hose, which will keep the boost from entering the OCC, otherwise escaping out of the OCC VTA valve. Under manifold vacuum the VTA valve stays closed, so there is no vacuum leak, and that vacuum is still retained on the crankcase.

I posted above a bit more on the VTA valve add-on. I hope this answers your question.

If you have any other questions, feel free to ask.

So, what you're saying is that with the VTA kit, the line to the IM remains in place. And the VTA piece acts in a similar fashion to the CFM breather that some people are running. That would be nice to have everything in one kit.

But, I am a bit confused. I was under the impression that the PCV valve closes under positive pressure. That is, it would only be open when there's vacuum applied to the crankcase or if pressure was equivalent. So, if the PCV valve is closed, the breather wouldn't be activated. I guess if the check valve on the breather opens quickly enough, the PCV valve would essentially always stay open. Is that right?

The other upshot of this is that since this is only partial VTA, any blow by that gets by the can would still go to the IM, just like any non-VTA can.

Sorry for 20 questions. The kit really does look nice, I'm just trying to wrap my mind around the VTA option.

No worries about the 20 questions! I enjoy when people ask about the products we offer.

So, yes, the VTA kit works similar to the CMF breather cap.

The PCV valve does close under pressure, however since there is a check valve in the line going to the OCC from the intake manifold, boost or pressure from the manifold, never reaches the PCV valve.

When there's excess pressure in the crankcase, it'll want to find the area of least resistance. Generally this can be taken care of well enough by the vacuum flow being pulled from the upper intake pipe, however when the crankcase pressure exceeds this vacuum it'll look for a place to go. this is generally on higher boosted ST's, where there is more crankcase pressure, due to more piston blow-by. The PCV valve on the FiST opens rater easily, so that pressure will go out the PCV valve into the OCC where it can be vented by the VTA valve. This excess pressure can contain oil blow-by, but since the PCV hose on the OCC is the lower hose, it still gets baffled by the OCC, and doesn't make it's way into the manifold.

I'm going to do a quick diagram on MS paint, to show what happens with the kit under boost and vacuum, to better explain this. Gimme like 15min.

So in these lovely MS paint drawings, that I am quite proud of, here's how the system operates under boost and vacuum. You'll have to imagine the VTA filter in place, as I didn't get any photos of the kit on our test car of it in place.

here's what the colors represent:

Green is vacuum flow, when the manifold is under vacuum
Red is boost flow, when the manifold is under boost
Yellow is crankcase pressure under boost
Orange circle is an open checkvalve
Orange X is a closed checkvalve

Vacuum:
Under vacuum the main checkvalve is open, and the manifold vacuum is pulling a vacuum on the crankcase. The VTA valve is closed, not allowing any un-metered air in.



Boost:
Under boost the boost from the manifold makes its way to the checkvalve where the valve is now closed and preventing boost into the OCC system. The pressure from the crankcase cracks open the PCV valve, makes it's way to the OCC and is then vented by the VTA valve which opens from the pressure as well. Total cracking pressure needed to open the PCV valve and the VTA valve is less than 0.5psi. It was hard to get a decent reading on this, as my gauge reads in incriminates of 1psi up to 60psi, but I barely got the needle to wiggle under the bottom mark.

Do you have a picture or diagram of the internal construction of the catch can?

From the bottom drain, note the inlet on the bottom left blowing directly to the oil scrapper:


From the top, where the VTA would attach:


Edit: wow the originals were massive [xx(]

Yeah I scoured the internet for the same before I ordered my can... only slightly creepy :p

Had not been seriously considering a OCC until now. Looks like a good project without cutting up any engine bay parts...and at a great price.

On your website, you have listed a green hose kit with the OCC. Do you by chance have a picture of the hose? I am curious how close to the DHM green it is.

Thanks!

Hope this helps! It's no where near as lively as green envy, and a bit more a faded green from the DHM green, but I figured we'd offer it.





Here's a shot of it on my buddy's Mazdaspeed6 build:

Went ahead and put an order in this morning! The discount code was MUCH appreciated! Cannot wait to get this thing installed. I'm almost at 13k miles now and I think I've waited long enough.

You won't be disappointed. It's such a well-made kit. Everything is just about perfect. I'm yet to hear of anything being left out of the box or whatnot, unlike other kits out there. The fitment is top notch, and functionally it's the equivalent or better of all the rest, I'm certain.

Thanks for the reassurance! I've been following all the OCC threads and talk for a while now and this one does seem like the best.

I'm a real-novice; this is literally my first OCC, and I found it easy to install. Reminded me of how I use to enjoy Legos and Erector Sets from my youth...so easy.

So I got this and the install was actually very easy. I've never done anything like this with the lines I had to take off.

Here are a couple of pictures of my install so those who have the race red or Molten orange can get an idea of how it will look.
