ive had it for a while now and am not positive on how to hook it up, ive searched, i know that there is one line going into the intake, and you plug that, and connect it to the catch can, but what about the other tube, there are 2 on the canister... help?

the can (catches) the oil that would normally end up in your intercooler throttle body ect. the return line lets the gases re-enter the system while the heavier than air oil settle in the can. hope that helps. if anyone has any pics of one installed on a blacktop please post them or email them to Ryanhelton2000@hotmail.com ive got one and still havn't put the darn thing on. having a hard time finding a place to put it.

This was posted on another tech forum (Boosted Hybrid). I hope this helps.

"There is two methods in which you can run the catch cans. One is to run the catch can system in the "open loop" set-up pictured above. You allow the oil to drain back into the block once its gathered in any amount at the bottom of the can. The second method is "closed loop", or to just run both the feeds into the can, and have the bottom plugged. At the plug there is usually a drain style fitting that allows you to drain the can periodically. Open loop is easy to maintain (nothing to really do), but closed loop is more effective since it doesnt allow any oil vapors to recirculate back into the block. I set up all my catchcans in the close loop set-up. The key thing to making the closed loop set-up work is mounting the catch can low in the engine bay to make sure that the lines coming into the can, can properly drain."

"You want to mount the can up high in the end bay so that the vapor can pass into the can, but the oil cannot (or at least slows it down considerably). You are correct that the breather in either situation closed/open loop will have atmospheric pressure within the can, but that is why you mount it up high in the engine bay."

Or you could do what I do and run the oil line coming off the valve cover pointing down towards the ground and just let the excess oil spary onto the road/crossmember/body... whatever it hits. I don't know about you guys but I don't exactly have gobs of oil coming out of my crankcase.

But if you have a polished catch can, you get +5 bling points so I guess it's not all that bad.
