Catchcan plumbing question...

Most catch cans only have 1 inlet 1 outlet, so for the ones where u need to attach 3+ hoses to it, do u just use a T piece etc?

The ones we use have 4 fittings, 2 inlet, 1 drain (outlet) and 1 filter. There is no reason why you couldn't use a T piece although a Y piece would be better for plumbing.

Even with the pictures im still clouded as to which way i should use mine

I found this photo, what does this setup offer?

This looks llike the 100% plumb back alternative. It is a little hard to see the PCV pipework, but I suspect that both the inlet and oulet for PCV is plumbed to the can. Certainly the inlet to the turbo is plumbed back, so it would makes sense if the PCV was similarly plumbed back.

Why are you still clouded?

For what it's worth here's my setup....figure out which one it is . Remember most bought catchcans have 1 inlet and 1 outlet the inlet should feed to the bottom of the can

As long as you block off the unused plumbing and fittings.  I gotta ask why though? :confused:

Well, we're recomending to block the PCV line on a vent to atmosphere setup, so if you block the plenum side of the PCV line, and use the PCV port on the side of the rocker cover, you get a very tidy catchcan setup with only one hose

This is the style of catch can we use. http://www.gcg.com.au/catalogue/Oil%20Filt...tor%20round.jpg

It has the 4 fittings;

*2 inlets on the side at the top (we run a piece of pipe to the bottom and then cover them with stainless steel wool, inserted via the large air filter fitting.)

*1 drain (outlet) at the bottom (we put a tap on this, so we can open it and drain it)

*1 filter on the top

Whats the best way to block the PCV valve? Cut the hose and put a bolt in each hose end?

This setup is the same as mine, it still vents to the plenum via the PCV valve when neg pressure is present in the plenum and vents via the catchcan to the turbo intake pipe when pos pressure is in the plenum....only diff is my catchcan is on the oposite side to shorten the tubing and looks tidier. There is no venting to atmosphere....it's on my street car....and legal

Yeh sweet that sounds perfect

Only thing is i want to block the PCV valve, seems to have all benefits and no disadvantages from doing so

So whats the best way to block the two holes/hoses? Im assuming just cut the hose going from the plenum to the rocker cover, and screw a bolt into the hose holes

The problem with this desiogn is it vents to atmosphere with no filter. :thumbdwn:

Hi guys on somthing of a different note why is the boost pressure sensor for a ebc teed off of the fpr pressure source?could it be teed off of the other side of the plenum where the boost gauge gets it's pressure reading from!:):)

[Trust33]

hello!:)

[51jay]

Yes

Hi 51jay as the post above my previous post says.

[51jay]

could it be teed off of the other side of the plenum where the boost gauge gets it's pressure reading from!............. Yes

[Trust33]

Thats allright then ill do it because i thought it was ok to do anyway i just needed to know if there was anyone who had any dissagrements.it's just let me make my hose shorter good thing.Thanks 51j

i went to power diggers workshop in ingleburn today and the owner told me that the boost pressure source could be teed from the vaccum hose that runs from the throttle body to the air con canister.I didnt question it because ive had one on the car in that exact same location ever since i bought it, it had just been capped which means it can be located even closer again.:mad:

A question about my proposed setup for an oil catch can.

1.In this picture you can see the pipe that goes from the plenum to the rocker cover.Now if i put a aftermarket pcv valve in the middle of this hose so pressure only travels to the rocker cover and not backwards to the plenum is this allright to do?

The catch can is rigged up the same as the one in the picture.

What i was thinking was that by putting the valve in there it would only flow air when on boost and when off would eliminate oil travel to the plenum when off boost.And the catch can setup should pretty much take care of the rest of the oil blowby on its way to the intake pipe.

tell me if i am wrong please.
