What do you have to lose by trying a repair.
If it does not work then replace the crankcases or buy a replacement engine.
If you go the replacement crankcase route you will most likely need new shell bearings and a lot of gaskets and seals which could prove very expensive. There are 6 different shell bearings sizes and the crankcases are colour coded meaning that if the crankcase you buy does not colour match your broken ones then you will need shell bearings or which there are 12 and are about £10 each
I would take it to a fabrication/engineering works and ask their advice
The area under the top mount is the crankcase breather, no moving parts in there. There is a metal plate between it and the gears on the main and drive shafts with a pipe down to the sump.
