Vent hose

[Paul0001]

Hello
I have a 06 Caddy 1.6 petrol 5 speed and a long steep, usually corrugated gravel driveway and hence some problems that I hope someone might be able to help me with.
The vehicle's idle started constantly alternating between about 4 and 15 thou rpm which took me under the bonnet to find the whole intake manifold having a fair bit of movement and sucking in air through a very short, broken rubber adapter/hose that is situated between the oil filler and what I assume to be the throttle body, at a guess I would say it is a rocker cover vent.
My first problem is that I can not find a replacement adapter/hose on the net and have no Idea what it is actually called which doesn't help.
My second problem is that I don't know how the intake manifold is secured, at present it seems to be loosely holding on by 2 or 4 screws (cant remember which) on the front along with the various tubes and wiring etc. I can see the afor-mentioned rubber tube supporting it to some degree but would have thought there might be something unseen at the back/underneath that might have fallen off or be broken.

Any help would be massively appreciated.

Can you post up an image or two of the broken pipes?

I'll be able to figure out part numbers from there for you.
