Tx box breather pipe - why is it dancing around?

I was looking for my cat (feline variety), hiding under the car, when to my horror I saw the tx box breather pipe laying on the ground.
It had somehow snaked itself down there - queer...

In fact it has happened before, but I put it down to myself fitting back the head and accidentally routing it downwards one way or the other. But this time it went all by itself. Weird, and potentially dangerous, as the frothy fluid from the box under load could find its way outside the car, while an upper-standing pipe would not let it escape so easily.

Has this happened to anyone else?:confused:

I can't recall wjhat the pipes like but I am assuming its a pipe with a little 'hat' on it. Make sure the hat is nice and loose and the pipes not blocked.

Sounds like the pressures working the bugger off.

On the rens we have 2 types of breather, the pipe and hat or the wee box. Might be able to get a wee box type to stick on it.

Used to have trouble with RWD motors poppign the pipes off and fillign the drums up with oil due to the breather being blocked, even only a little bit can make a fair bit of pressure build up in the casing.

its just a slim fuel hose type affair that lives free to atmosphere around the header tank right ? the one you fill the transfer box from.

it did puzzle me why they would just leave it to its own devices, not even a plastic S clip holding it to another pipe, nothing.

Yep my txb had gone it was pi$$ing out fluid everywhere :(

well, the 'reusable' ones I couldn't reuse so I had to cut.
I've got the damn things everywhere, but now I'm getting paranoid - how do I know that no fluid escaped as I was driving with the hose dragging on the read?

I didn't do any silly speeds in the meantime, not over 120 anyway (I hope that's when it gets frothy and tries to escape)

JohnA - stop worrying.

The standard breather pipe is a small rubber pipe connected directly to the top of the transfer box. i.e. the highest point. You will not have lost any fluid, and it does not froth.

It should be routed up the back of the bulkhead, away from any moving parts, the end turned over and tucked behind the water header tank.

The pipe should not restrict the function for breathing.

Attach some small nylon ties, at appropiate points where the pipe passes by - not to tight but tight enough to hold it up - make sure there is some slack where appropiate for movement.

It is not unusual for the pipe to fall to the ground and left long enough it becomes considerably shorter.

Thanks Richard.

...you say it doesn't froth?:D
I've seen it spitting it's guts from the breather after a 'spirited' drive (years ago, when I was test-driving turbos to see which one I'd like to buy...)
Drip - drip - drip from the pipe, driver's side
When it was cold everything was OK (don't think they had used Vaux fluid in there, perhaps):beer:
