Where does the line run from? one goes to the intake pipe, where does the other line come from?

theedge

Of the two coming from under the intake manifold, one comes from the air oil separator and the other is from the idle control valve.

I'm running one line from the Oil / Air Seperator into the catch can, and one from the catch can into the intake pipe after the air cleaner and before the turbo.

That should be OK right ?

theedge

Yup

So what are the upsides/downsides to using a catch can?

theedge

No oil vapors in the intake to get into the combustion chamber and bugger things up, a proper setup keeps at least some vacuum on the crankcase which is good, no mess in the pipes.

Downsides are mounting it and more hoses, and its one more thing that has to be drained and checked but otherwise nothing.

Ight let me get this right! one line going into the catch can connects to the air oil separator and the other is from the idle control valve or in the intake pipe?.

theedge

No thats just what mine is. A line goes from the AOS under the intake to the catch can. From the catch can a line goes to that port on the J-Boot. The loose line is just my replacement for the stock idle control valve hose, it has nothing to do with the catch can.

Alright great answers guys. Ive been looking to install one where my winsheild washer resevoir will no longer be! Now Just how in the hell i het that out...

ahhh, am I going to have to pull the intake again to get to the AOS???

theedge

Yup, unless youve got very small hands

Just a quick update, I'm 99% done with the catch can.

I went a little over board and got some AN fittings and Braided Hose

That was one if my questions, how do you empty the Greddy cans ?
I think that the unit for sale on Ebay has rather small passages /tubes compared to the greddy unit. would it not be a little restrictive?

TRACKIN951

Nice clean install! i am planning on doing mine with braided lines also. What AN size is that braided hose?

So the catch can gets the oil/blow by before it can get into the IC/intake?
