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?

Thanks

Cleaned and preheated. Smoke the part with acetylene soot untill black, then with a neutral flame heet untill all soot is burned off. That is the proper temp for welding. Aluminum MUST be totally clean to weld.
