Now why didn't I think of that? haha, But you would need, or should have, a check valve in place to prevent the crankcase from sucking anything back in... such as road dust, salts, water, etc., etc..

I haven't done it on this car yet, but there's a check valve on most crankcase outlet. Obviously if you're worried about being environmentally friendly you don't do this. You will lose some vacuum on the crankcase but since you're wide open to atmosphere you blow off positive pressure in there fast.

[JimmyMac]

I would run 2 check valves if you are worried about losing vacuum. The one on the block, and one near the end of the hose. But I'd just run my Saikou Michi OCC. Designed right and 1/3 the cost of these new to market OCC's.

[Jeff86]

Well you will lose vacuum because it's not hooked to the IM anymore... but who cares. Venting to atmo you will blow off positive pressure. I wouldn't want an additional check valve in the way though.

[JimmyMac]

My question with this OCC, It vents to air and sucks in fresh air. Got it. Does it get pressurized from the boost pressure in the intake manifold for a turbo setup? Do you have a valve in there somewhere to prevent this from happening?

[ANTI_LAG]

The catch can lines hook to the line off the back of the IM and the line that goes to the intake tube. Those then get plugged.

As for pressure in the catch can, there Isint any as the pressure releases from the filter. Also at no time does the crankcase suck in air, the filter is there to prevent any oil residue from coming out of the can. Crankcase ventilation will always be positive.

As for not running a can and dumping on the ground, that's a no no at a track, as no one likes sitting around while the track gets cleaned up from a oil down or while they pull a car off that hit a oil patch. While there Isint a lot of oil passed out in the event of a blown motor you would have a lot of oil release if you say melted a piston or blew a hole through it, which then you could oil down and run over with your rear tires and possibly crash.

If you go to a track day without a proper catch can and they see it they will not let you run.

Great attitude showing how little you care for the safety of everyone else on the road. Next time it's raining have a look at the water beading on the oil slicks at the traffice lights and feel proud for your contribution to the death toll.

For about $180 you can get one of the best catch cans made, stop contributing to the road toll and make your car legal.

Crankcase blow-by is vapor. It is a small amount of unburned fuel and exhaust gasses. It's not going to create or contribute to an oil slick in any significant way. That's why people are asking how these cans are baffled in order to actually separate material out of this vapor. It's more of an atmospheric pollutant and is far less significant than everyone who runs around with a turbo system with catalytic removed. This is, however, why I said "Obviously if you're worried about being environmentally friendly you don't do this."

[Jeff86]

I do have to say to the vendor that this is a VERY nice looking piece and beautifully made. If I were of a mind to use one, and this one proved to be effective, I'd certainly consider it.

[ANTI_LAG]

Thanks we appreciate it.

And I would like to add on the info of baffling, the reason most catch cans have it is because if you are not venting to atmosphere like ours you will be having a constant suction from the can to the intake, without a baffle in place you would just suck the oil through the can without it falling to the bottom.

And we have been getting some inquiry's, I will try to answer any questions about our products on here but if you would like to order please pm the OP of the sale thread (Evan@D3PE), he can get you set up as well as answer any questions you might have.

My catch can stops all the oil from getting through as it's filtered. The oil drains down into a pipe with a tap at the end which I drain on a regular basis. It also has a relief valve in case the filter gets blocked but that hasn't happened after over 40,000km and I should replace the filter at this stage.
The stuff that comes out is dark acidic oil and not very pleasant.
I use a catch can because I don't want this stuff all over the compressor wheel, filling up the intercooler, clogging the inlet manifolds and burning in the cylinders.

I agree that leaving out the cat is a really bad thing to do and stinks for anyone following but I was talking about dropping oil on the road and reducing the braking distance for others wherever you go.

Do you guys expect your Turbo Kit to be released soon?

I have updated our original post to include our Series 2 catch can which is made to work with Full Blown, P&L, Treadstone, and AVO turbo kits as well as the HKS and Vortech supercharger kits as well as stock intakes. Pricing is the same for both units.
