ready to make catch cans

[gtlegacy]

ok im at the stage where i want to make my cans ?
i have a td05h 16g at 14psi in an ej20g

i plan on running a in from side 90* to bottom and a breather filter on top with sum mesh or sumthng inside

1 What pipe diameter would be optimal in my case the standards have 16mm inside diameter this is the 2 from the heads and 1 from crankcase linking with LH head ( i can modify the breather fitting on the head )

2 Will making catch cans upset the pcv ? how will i route this into the set up ?
do i need 2? if not wat do i do with it ?
the pcv is under the throttle body on intake manifold right?

3 is this the usual way the lines are routed ?





also i need some help on the intake side of things the the IAC

I have an hks recirc bov so im going to make a new bit of pping where the black box goes to flow the waste air back into the intake

where should the IAC pipe be added into the equation ? it will have to be somewhere in the new pipe it will be the same length and diameter as the black box

do i need to add it in at all ?

Why do you want to run a catch can?


The stock PCV system works pretty damn well

I'll give you my experience.....they're more or less worthless.....at least an open can setup.

I put the Greddy one on my car when I did my AWIC....which was about a year ago. The line going away from the can has oil in it. Maybe it's catching a little, but I'm not overly impressed. Maybe I need to put some steel wool in there....I don't know.....but all I'll say is that it really isn't working that well IMO.

Your car has a catch can in it. It's called the oil seperator cover, and its behind your flywheel in the bell housing.
