Hi,


Ive just re filled my diff and geabox with oil and there is a small hole in near where the diff and the gearbox join that seems to be leaking. Is it an overflow or do i have a problem?


Cheers

Its a 340 manual 1.7 btw....

Without seeing, I would say that it is a problem, there is no overflow that I would know of.

The overflow is the filling hole itself, at both the diff and gearbox.
If it leaks through the gasket between the diff and gearbox, you have a problem.

Check out this post as to diff / gearbox gaskets, which ones are still available:

Its near the diff/gearbox connector but not the join itself.

its like a small square hole. Looks factory (even and everything)

Is it a breather?

Breather is at rear of diff virtually at the top of the rear plate.

Sounds more like the fillerplug.Sure it's not threaded?

Bung a clean rag in if you need to move it.

Pics might be an idea to show where you mean.

Ill try and get pics up today, its a smal square indent that seems quite deep, it only leaked when i lent it on its side. Defianly looks like if should be there tbh just dont get what it is.

Chillax mate, it's an overflow. Forward of the join between box/diff, high up and on the right hand side of the car? Rectangular and weeps after filling the box with magnatec 40w? Same here.

yay , thats what i wanted to hear! lol

Was guessing it was but didn't wanna risk it.

Bleed the brakes and change the sump and shes all good to go!

woop woop

Keep an eye on it all the same in case it's a crack or whatever, but mine did the same then stopped after about 30 mins of slow seepage.

Yea i noticed t at first as the box fell slightly on its side.... but once mounted and straight its fine, just a slow seep and then stopped.

Cheers for the help

A little bit of seepage is nothing to worry about.

Thats what the doctor told me anyway.
