catch can question

[91Supra313]

Wondering if anyone has ever used one of these ebay type oil catch cans? So much cheaper then a GReddy, but looks to me like it does the same thing.

Yes, Mine is similar, just round.
However, the best design, is to have a wall, inside the can, separating the inlet side from the outlet side, so that all air is forced down to the bottom, and then up to the outlet through a wire mesh, to allow the fumes to cool.
The mesh captures the condensated oil. Ebay cans don't do this. What I did, was add a tube inside the can, to force the inlet air to go to the bottom, and added some stainless steel wool.

Wow! I have been looking for this thread since I posted it. I had no idea it was moved. I guess it doesn't belong in the oil section.

Ok so there has to be an outlet on the can? Where the heck to I vent it to? My friend has both lines for his GReddy can going to the valve covers. One for each cover. I always thought that was how it was supposed to be installed. If anyone has any pics of their install please hook me up so I know how to put mine together. After I find one I want of course...lol. I was looking at one from NRG Innovations.

^ Unless there is also a vent hole (ideally going to a vacuum source, i.e. turbo inlet hose) in the canister, his is setup extremely wrong and he should fix that before it blows a seal out (or worse) due to crankcase pressure.

Thanks for that one Poodles. I sent them an email for a custom can quote. Still wondering if someone can post a pic of their setup.

I'm using driftmotions catch can. http://store.driftmotion.com/static/i-oilcatchcan.php

I'd say comparable to greddy, pretty good quality. I welded the inlets and outlets to the can, it had no leaks before the welds and no leaks after. It definately gets the job done for me. I am running a N/A and dont know how this effects your judgement. Take a peek tho.

Also, having no vent back into the system is bad as poodles said. I T'd the outlets from valve covers and used outlet on can as vent.

Mines setup same way except on N/A it goes right to the TB as there is no port on the intake tube from filter to TB as in turbo.
