Hi,
I presume the gearbox is out of the car?
My first question would be why change the gasket? If the area is oily, are you quite sure it's leaking from this cover? It's just as likely to be coming from the 1st motion shaft bearing or indeed the rear main of the engine; or even drifting down from the block to crankcase joint... I could go on.
The 'cover' in question is the front layshaft bush. I'm not 100% sure without going out into the cold & dark to check, but I think to remove it you would have to first remove the clutch pedal shaft, which in itself is not something I'd undertake without a jolly good reason. It's conceivable that you might pry it out far enough to get some sealant in the joint, but I'm not sure I'd recommend it.
If this is a 'running repair' I'd suggest to leave well alone until you are ready to undertake a more extensive gearbox overhaul. There's no shame in a little weeping of oil. If however it is pouring out a more extensive overhaul might be called for.
In this case I would direct you to Harold Perry's account of a 4-speed box stripdown in 'The Austin Seven Companion', which tells you pretty much all you need to know. It's not especially hard to strip and rebuild a 4-speed box as long as you proceed carefully and methodically.
