That crack can totally be repaired with a TIG welder, but to do it properly you'd be taking the engine apart regardless, so unless you already have the the tools and skills it's probably cheaper to just get a replacement case or engine from the junkyard.

(not to mention it sounds like you're going to have to go through the whole system looking for metal chunks anyway).

However, I'm sure some guy on the side of the road in Thailand with an acetylene rig would be able to do a miracle job closing it up enough to get you to Bangkok without disassembling anything.

So I have to investigate the clutch thing anyway, but even if I wanted to TIG patch it I’d probably need to remove the case either way, no? Unless this is a thing that can be welded in-situ at which point I’m just lugging around a heavy engine.

Depending on how well you can clean the area around the crack inside and out, you might not even have to take the engine apart. If it's a non load-bearing area you don't care about it being particularly strong, so you can just glob a bunch of metal onto the hole and file it flat. You (or the welder) will just need to ensure that the areas around the crack are wire-brushed or sanded to bare metal, and that all the oil on the surface to be welded is removed. It's also good practice to disconnect any electrical components if you haven't already.

Or just JB-Weld it like cursedshitbox says. This is exactly what that product is made for


E: also you keep saying magnesium but other people say aluminum. Which one is it? Important for the welder to know
