Default Re: what are these engines made of?

They're cast aluminum, most likely recycled or a low grade alloy... epoxy wont be strong enough to repair that area but you could fix it with a few alumalloy rods and a propane torch.... but by the time you bought both, you could have purchased a new set of cases, then just swap out the broken half.
