Make a gasket. Anyone who mends machinery should be able to make gaskets. I'm sure there will be lots of U tube videos on it. Avoid the "smack the gasket on the casting with a hammer" videos, that works for steel and cast iron, but can distort aluminium. Gasket paper can be got from any engineers suppliers, but you need to be fairly close in regards to the thickness, compared to the original gasket.
