Re: What do i do with this?

If it was a vacuum pipe then a plug would have worked, but it's not so it needs to go back into the induction system somehow. You could do with measuring the outer diameter of the crankcase breather (the big one on top) to make sure it is 25mm (it looks like it) but you don't want to order anything that you don't need and end up having this take ages to get set up 'cos you gotta keep ordering new bits.

In response to your PM (I hope you don't mind as it might help anyone else doing this) assuming that the spout does need to be 25mm, then you should only need the one alloy t-piece (which will need to be 70mm to fit between the 2 bits of silicon). Rather than adding another expensive bit of alloy, I'd use a small plastic t-piece. It's difficult to visualise, I've adjusted the picture, I hope it makes sense

Re: What do i do with this?

sorry mate but im still not getting it.

Why does the GSR only accomodate for one pipe?

I dont see what you've done with the plastic t-piece there

sorry, it seems so simple but just getting mixed up here

Re: What do i do with this?

Honestly, I've no idea what the GSR kit does with the smaller pipe, hence why I asked the question earlier The plastic t-piece would go between the alloy t's spout and the crankcase breather, with another smaller pipe going to the inlet manifold breather.


Actually, thinking about it, the whole point of the crankcase breather is to return any excess oil to the engine via the air intake, which goes into the inlet manifold anyway, so I can't see the point of the inlet manifold breather. The fact that it's there makes me want to connect it to something, but I don't actually think it would cause problems if it was plugged.

Re: What do i do with this?

well surely you would just use the existing crankcase breather pipe?

bit like this?

Re: What do i do with this?

Can anyone confirm the setup above?

Also eklipze am i right in thinking:

Cold air intake = 70mm
45 - degree elbow = 70mm
First alloy t-piece = 70mm, Outlet = [size of plastic t -piece]
Plastic t -piece = [size of first t-piece outlet], outlet = [size of inlet manifold breather]
90 degree elbow = 70mm to 60mm

Re: What do i do with this?

Aye, that sounds right to me, and your picture is what I was trying to get at but it didn't really work, hehe Of course you'll need some short lengths of hose to connect the breathers up but need to know what size (inner diameter). You could maybe get away with using the original piping and chopping it to fit, since your alloy t-piece will be in about the same place as the crankcase breather that might actually work. Saves you buying any extra piping, etc Just need to check the original pipe work will fit over the outlet of the alloy t-piece.

Re: What do i do with this?

so you know when im getting measurements, say the outlet for the t-piece is 50mm. If i get a plastic t-piece, does that want to be 50mm aswell, or a bit bigger?

were getting there mate

Re: What do i do with this?

If the inner diameter of the pipe is 50mm (which it won't be but for arguments sake ) then the t-piece needs to have an outer diameter of 50mm. They are usually barbed in order to give a tight fit.

Re: What do i do with this?

last thing then, does the piping go over the t-piece or inside it. not the outlet bit, the main part?

Re: What do i do with this?

The alloy goes inside the silicon When talking about solid pipes (alloy, steel, brass etc) the diameter given is (more often than not) the outer diameter. When talking about flexible pipes (silicon, rubber etc) it'll be the inner diameter. Occasionally it's the other way around (PC watercooling being one example) but for cars that's a general rule.

Re: What do i do with this?

confused yet again.

Here are measurements:

Outer crankcase breather: 24mm.
Inner crankcase breather: 20mm

Outer manifold breather: 12mm
Inner manifold breather: 10mm.

That's fine, but the outlet on the alloy t-piece can only be 25mm and no smaller on their shop.

And, the plastic t-piece will need to be 20mm to fit on the alloy outlet, and the crankcase breather at the other end.

Also, the biggest plastic t-piece they do is 10mm outer diamter.

Something is a miss here.

F***, i wanna get it ordered

Re: What do i do with this?

The 25mm outlet on the t-piece will be fine, once you've got your jubilee clip on the crankacase breather side it'll make a fine seal. I'd get this - should be exactly what you need

Don't forgot you'll need about 25cm (if that) of 25mm rubber hose to connect the crankcase -> plastic T -> alloy T and a length of 12mm rubber hose to go from the plastic T to the inlet breather, maybe about 50cm.
