How to fit a gti inlet manifold to a 1.816v / 2.016v

[devilchris]

Hello guys.
I have a 306 S16. I disassembled the original intake manifold. I mounted the intake manifold of the 306 GTi.

I'm stuck because I do not know how to connect some pipes.

before I post the pictures and then I try to explain my doubts!















Speaking of the intake manifold S16 I understand that:
4 - the tube that sends the oil to the engine.
5 - are the two tubes that control the dual valve timing of the intake manifold.
6 - is a tube that arrives to the control unit to control the depression of the intake manifold.
7 - I do not know what is its function.
8 - I do not know what is its function.

Speaking now of the intake manifold of the 306 GTi:
1 - I do not know! (I think it's a vacuum socket)
2 - is the aspiration for recycling oil vapors! (correct?)
3 - is the aspiration of air to keep the engine at idle.

Now let's talk about what I did not understand.
In the transition from collector to collector S16 GTI there are 2 or 3 small tubes that do not know where to connect.
5 - where do I connect the pipes n. 5 that in the collector S16 commanded the double timing?
6 - The tube n 6 arrives at the control unit. Where do I connect the collector of the GTI?
7 - Where do I connect the pipe n. 7 in the intake manifold of the 306 GTI?

1000 Thanks
