Default Catch Can Plumbing

Hi All,
Ive done all the install for the mounting of a catch can to my Nav. (D40 ST-X V9X).
I can't finish attaching the hoses due to injuries at the moment. Getting a mate to do that for me i hope.
Could someone tell me where the outlet pipe from the can attaches to the inlet system so I can give instructions to my mate.
I want to use the same inlet port as the std PCV setup. Got the pipe from the PCV to catch can worked out ok so thats sorted.
I cant get my head in and around the engine and induction pipes to find where I need to attach the outlet from the can back to the inlet system.
Any help would be really appreciated.

There's a hose that runs from the PCV outlet on the camshaft cover to the air intake just before the turbocharger. You have to take one end of this hose off to install the catch can.

Let's say you disconnect the PCV side. You now have a hose still connected to the intake pipe just before the turbocharger. You connect the other end of this hose to the outlet of the catch can. You then put a new piece of hose from the PCV on the motor to the inlet of the catch can.

It works similarly if you disconnect the intake side of that hose - you're left with a hose connected to the PCV. Connect this to the inlet of the catch can. Then connect a new hose from the outlet of the catch can to the intake join that the first hose came from.

Put simply, you have two hoses (represented by ==== ) that go like this:

PCV ========== Catch Can IN -- Catch Can OUT ========== Intake pipe

Hope you recover soon.

V9X Catch Can
________________________________________

1. Remove pipes to and from turbo
2. Remove small coolant line and hard pipe/bracket and push up behind fuel lines.
3. Undo the 4 bolts holding turbo manifold, rear bottom last (loosen)
4. With the last bolt in you can turn the manifold down, now remove the two 10mm bolts holding the black PVC Valve.
5. Everything away, I used 16mm hose and run it out to the front of the air box.

Many thanks Old Tony.
Once again a concise post. Although I had the plumbing arranged as your diagram sets out, there is some comfort in a confirmation.
Thanks to you too Bazt. Your post gives clarity to the procedure to be followed.I notice you have an RD Technics tune done to your Nav also.
Like to offer up any comments? Did you get a remap or tweeak on a few things?
An ECU remap / tune is next on my to do list. EGR shut off is my priority
Just need to find someone/outlet to get to do it.

Bazt, can I ask precisely where the hose connected "to the front of the airbox" is connected to? Is it between the air filter and the turbocharger?

I think he means he ran the hoses and placed the catch can in front of the airbox...

Pretty sure of the same, but there are going to be people who come past the thread later and read it and not make the same assumption. In the interests of saving their air filter, I thought I'd ask the question! :)

This is correct Bods.
Tony, I have a couple of how-tos with pics etc on this but cant get the whole articles to transfer to this site so just pasted the text which left things a bit unclear.

I made the same assumption.It's about the only place to mount a can with the engine installation the way it is. That's where I've put mine too.
It looks to me that the PCV outlet points down, say 6 o'clock. Can it be rotated to say 9 o'clock, pointing out to the passenger side of the engine bay, to allow an easy fit up for the pipe out to the can? Would make it easy if it does.
