Thanks for suggestions so far.
I am using a semi synthetic oil. 80/90 so I'll try and switch to plain oil to see if that works. I think the seal may be the older type. Speedo drive and earth screw are clear of blockages. The seal is mounted the correct way around with the spring facing the oil.
Alibaba, I was under the impression that the notch in the gearbox casing needn't be siliconed if it is of the newer small type. The last box I had required the silicon filling as it has a larger V shaped groove in it and then I drilled through a 1mm hole so that it could still breath out of this. This box has the newer smaller notch already and I thought the problem of oil leaking out had been corrected by the manufacturer so I didn't have to silicon this one. The notch is a lot smaller. You think it still needs doing? And you do still think I need to drill a hole back through it so that it can breath?
Thanks again
