I just bought a catch can...

[7M-GTE]

That'd work on an N/A but better to stick with the TB port rather than the intake manifold. On a turbo you could connect the valve covers to one port on the can and the other port to the accordian where the stock line went. Still not the best set up but an OK compromise. Always consider what the pressure differential across the two ports will be.

The can is nothing more than an air-oil/water separator. Separators work as either inertial, coalescing, condensating or a combination of the three. If the can comes apart you can tell which principle it uses. Btw, stuffing it with some plastic scrubbing pads or similar material will make it more efficient as long as you don't choke the flow. The added material increases the surface area and aids in coalescence.

thats what I was tryin to say I just couldn't word it like that... thank you...

In the N/A setup the pipe goes directly to the intake manifold.... in the turbo, it goes both to the intake manifold and to the accordian hose. Correct?

So if you route the fumes from the covers to the can, and then just to the accordian hose, aren't you loosing vaccum that was also being drawn from the intake manifold? Wouldn't the proper way to be to T it off to both spots like stock?

Also if just routing it to intake in one spot, wouldn't it be better to put it at the intake manifold rather then the accordian hose? That way whatever oil remains in the fumes aren't pulled into the turbo and your IC/IC pipes?

One more question --- Do you guys that run it to your accordian hose just cap off the port on the intake manifold?

Thanks
