Leaking gearbox

[harbourseal]

I've got an ongoing leak from my sinpar gearbox.
All the oil seals have been changed and the paper seals behind the differential

I think the leak is coming from the seal in a he middle of the gearbox.
It's a 354 gearbox with an added part for the 4x4

This winter I will be stripping the gearbox and change all the paper seals again. But for now I need a quick fix.

Does anyone have experience with. Millers oil leak stop or another aditiff to stop oil leaking from dried out seals.

Today I've changed the gearbox oil for a doped liter of new oil.
I doped it with http://www.wynns.be/product/h-p-l-s/

And I found part of another leak problem.
One of the bolts that holds the 4x4 gears in place on the actual gearbox was stripped. It was held in place by just one thread and just hanging in the gearbox.
I replaced it with a slightly longer bolt.
I hope the leaking stops now.
