Welding cast aluminum

My brother has a dirt bike with a crack near the oil drain plug. the previous owner must have been confused when loosening the drain bolt since it is upside down. This is casusing a leak and the bolt can't be tightened much.

So how to you properly fix this area? Weld it up? Should it be dissasembled before welding? Any preheating on the cast aluminum?

Welding is best but if you can get it clean enough you might try a good epoxy.
