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

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 :D

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

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.:cheers::(:mad::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.

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
