Hi speedy,
My attempt would be to make up a sheet metal patch to fit over the hole,about 10mm bigger all around, fold it up the side if it needs it. I'm not sure if I would use JB on it as it goes hard, but it might be ok. My preference would be to use something like 518 Loctite gasket maker because I know that works well and can handle gaps and withstand crank case pressure, then put a couple of pop rivets to hold it in place. Make sure you seal over the top of the pop rivets. Problem is the Loctite is expensive but you don't need a pot to get a good seal. As for the seal I would fit it and then JB over the damaged section
