Nowhere, it's just a breather, there's a pipe that fits to it so your box breathes plus it stops gearbox oil getting out

It is just that a breather stick a short piece of pipe on there and point it towards the floor

standard one is similar shape to a hockey stick but use any sure its similar to vacuum pipe as long as it dose not kink

Oh ok so its fairly normal to leak a little bit? The amount the oil cost would rather it stayed in the box lol

lol it does a bit surprising how the pipe stops it but even with pipe it can don't worry looks a lot but its not will level itself just as far as I know stops oil bubbling in sealed box. Allows breathing

the curve n the stock pipe is quite important as it works similar to an expansion pipe on a central heating system so ideally you need to put a loop in the pipe and tie clip it so its standing up

if you don't do this and you take car on a track it will chuck the oil all over the place once the box oil gets hot

Bloody hell all the ones i have ever seen have been on upside down ie short piece connected and long tube pointing down. And i have seen alot of boxes just goes to show all must have been fitted wrong

I can see now how this works but i realy am shocked i am talking 15-20 boxes all fitted with no tube,a pice of vacume pipe tucked down inbetween mount or fitted wrong over 5 year not one fitted right made me belive that it went the  other way  Shocked Simple now you see it like this i honestly thought it was breather rather than expansion breather

Hi guys im after some help here to do with the gear box breather. Mine has original but it was lay down and all of a sudden started leaving abit of oil on the floor after use. Ive now stood it up verticle after advice from bob'thanks pal. Its still leaking a little and only after a short run up the road and the box isnt even warm. Ive checked the level and it is a little low so i need to get some for it. Why on earth would it be coming out even if the box isnt warm? Every gear works great,no noises and is lovly and sensitive on the stick in and out of gears and pulls like a dream. Would any one know whats causing this and how could i stop it. Its never done it before and ive had the car for 2 years. Im concerned that sumat is gonna blow! Cheers

I once spoke to someone who mentioned oil galleries/channels blocking

Lee assuming the pipe is now standing up vertical with the loop at the top it should not really leak.
Inside the box there is a series of plastic channels fixed to inner upper casing which act as a type of deflector to channel oil back so it's possible that one of these may be broke or has come u clipped but to check that the gearbox end casing will need to be removed.
The other possibility is that somewhere there is massive wear in the gear set this will generate heat which in turn will cause oil level to rise, but once again difficult to say unless inspected.

I had this problem with a quaife once on the track (especially on hot days) so this is what I did to resolve the issue.
Take the looped pipe and run it to a 3 way catch can (you can make one easily enough or buy one), run another pipe from one of the other ports back to the gearbox.
I drilled and tapped another fitting to the top front of gearbox casing so the oil that got pumped into the can simply drained back to the box. You will need to use the spare outlet to run an external breather filter at the top as the box needs to breathe.
Also with mine I ran a seperate oil cooler to try keep the temps down which all worked fine for a while
Then one day the box went bang and that was it yoursofunny

Was good whilst it lasted though lol
was mainly caused by a shoddy gearbox build with incorrect overly tight shim clearances which were putting way to much loading on gearset, this was generating a lot of heat which caused the oil level to rise.

Seriously though it's worth a try though lee Wink

Ok sounds good bob thanks for your help ill have to give it a try. Coming home from work last night i cruised a stretch of bypass at 60mph for about 3 mile and when i braked gently for the roundabout the steering wheel started to shake which its also never done. I went round the roundabout slowly and it was still shaking'felt like a front tyre was totally flat. The shaking got worse and i just cruised threw the town at 20mph luckerly not far from home. Ive took both front wheels off this morn and nothing seems wrong. Steering works and all bushes look good. So went out again and it dint do it. Used it again tonight and it did it again. Ive noticed if i coast out of gear it dosnt do it but then when in gear and the car pull gentle the steering wheel starts to shake! Sumats going wrong pal lol. i wonder if these two things are conected the shaking and it throwing oil out?

Yes could well be connected lee
I'm gonna hazard a guess and say your diff bearing in the gearbox is fooked
Check for lateral play in the driveshafts at the gearbox end, if there's lateral movement then almost certainly diff bearings
This will cause overheating issues with the box and also give you vibration and steering wobbles as play will be transmitted to the hubs
If there is play I suggest you get it sorted whilst you have a gearbox left. We had one down here recently where the bearings had gone and eventually it led to a cracked casing and major damage to the gearset so just a pile of scrap now
