Pete, thanks for the reply and advice. Makes sense to me. Do you know if the fill bung level is above the height of the input shaft? and if you are supposed to fill the gearbox with fluid until it reaches the fill plug level? Thanks in advance

Ah .. so its more than likely it just needs a new gasket? Is this a common issue?

My 1360 Herald kit car project even when sat for a long period of time leaks gearbox oil .. its constantly wet along the bottom bell houseing joint highlighted in yellow .. ive done a little research and spitfire gearbox has a bolt with a copper washer that mates with the input shaft.. is the Herald gearbox the same? Is it common for them to leak like this from the bolt with the copper washer? It needs 3rd / 4th syncro so I need to pull it any way, but id like to know why the leak is so bad in this place even when stationary .. Thanks in advance
