What was the name of that "welding rod" I saw on TV a few years ago? You know...heated with a propane torch....
If it was on an installed motor I would most certainly say fix it , but right now if you replace it you are not out much $ if you look for a used one . But if for some reason it did leak then you would have to pull the motor to fix it But as Dino said it can be tig'ed and machined flat again , anything else i wouldn't trust but i would def trust it if it was fixed correctly .
This video will give you confidence on what a good shop is capableof welding and repairing !

You can weld it, but you may have trouble getting a clean weld. The oil kind of soaks into the casting and sort of seeps out when the arc heats it. I had to get mine welded up, and it sealed just fine. The guy welding it just didn't enjoy it too much.
WOW... those where some jacked up heads!
I'll probably end up putting the cracked one up for a few bux if anyone wants to take a stab at fixing it. I'm sure there are a few people here that have the tools and experience to fix it. I'm not one of them .
