Does anyone else have any input to the problem?

Yes youre probably right but whats the anoying part is that was it something i did to cause it as it was ok prior to fixing the leak or was it just a coincidence that it happened just after i fixed the leak?

Thanks for getting back to me Airhead, it seems to come from the back of the gearbox so it may be the breather and it looks like a clear hose.

Hi all, I'm new to the forum just looking for a bit of advice on an old dt125. After a recent crash i have noticed oil leaking from the gearbox cover, i managed to remove all screws holding it on and the radiator hose etc and used a tiny amount of instant gasket to see if it would seal it. Put everything back together and put fresh oil into gearbox and topped up radiator, after starting the bike it seemed to have sealed the leak but there is oily water i think coming out of an overflow pipe and i'm not too sure why as it had not done that earlier on when it was running. I'd appreciate any advice you have to give me on this problem. Thanks again.
