Crawford catch can's anyone interested?

[Grishbok]

That's true, your not going to make that design on your own. That design also doesn't warrant a 300$ price tag. It is also true you can make one equally if not more effective than that on your own. You are right though, just because i wouldn't pay 300 for that, doesn't mean you all can't. If you are comfortable paying that much for a catch can, well I suppose you can't put a price on peace of mind. I would highly suggest researching them and making an informed decision though.

I vote for the group buy

I don't think this is a catch can.... Doesn't this recirculate the oil back into the motor? Or does this need to be emptied from time to time? If it recirculates, I'm interested, if it needs to be emptied (catch can), then this is priced wayyyyy too high.

It keeps the oil away from the motor, regardless if if needs to be emptied or not it is race proven air oil separator.

If it needs to recirculate, then you need to fix the motor. How much blow by do you expect with a new engine?

I definitely am down for a GB.

it's NOT a catch can. catch cans simply catch what was going through the lines, and you have to empty them, most of the time, hiding the fact there could be a problem with the motor.

this is an air/oil separator, which does a different job. you're paying for 300 worth of engineering and saving your motor.

It is not just a simple catch can, it is an air oil separator.

The Crawford Air/Oil Separator effectively removes the oil from the air coming out of the engine’s ventilation system via a two stage process:

- The first step in the process is a large volumetric swirl pot. The function of the swirl pot is to use centrifugal force to remove the oil from the air. The air is then passed through a second chamber (see second step below), and extracted through the top of the AOS. Gravity then sends the remaining oil down the walls of the swirl pot and collects in the bottom of the AOS. At this point the separated oil sitting on the bottom of the AOS is returned to a baffled chamber in the center of the engine block.

- The second step involves a second chamber located within the first chamber. As the separated air moves up inside the AOS, it must enter the second chamber before it can vent out the top of the AOS. The function of the secondary chamber is to remove any residual oil that may have made its way up the swirl pot. The secondary chamber also has a drain to return any separated oil back to the engine.

The newest version of the air oil separator features a coolant line pass system, which helps eliminated milky residue when driven in cold climates or short trips. Making this ideal for any street going car, or full blown race car!

Yes it returns the oil to the engine and guides the vapor (gas) to the combustion chamber. Still called a catch can because it catches the oil and separates gas and oil but this one returns the oil draining it to the engine.

no its an air oil separator...

For 300$, that catch can had better perform magic tricks and poop white bunnies when you drive.

Should be just as effective as the Crawford one for less than half the price. I ordered one last night.

Easy install too. Here are pics on a BRZ.

moroso also makes a great unit.

[Neziah]

I think the major difference between those two is that the Crawford is temperature controlled by running your coolant through it and the Moroso is not. I recall reading they do that to prevent condensation forming on the inside and mixing with the oil or something along those lines. But I can not find that article >< I just read it a few days ago also. Seems like that would be more of a problem for a daily driver than a race car.

Maybe someone with better Google powers can find that article.

That is the V2 of their AOS. Crawford stated in the Catch Can thread that since the BRZ does not have a hood scoop the coolant lines shouldn't be needed for this application as they should have no issues with freezing.
