Is that the only cracked place on the right side half ?, what about the left side.
I know only a patch, would be good for just so long & the high dollar pocket folks will say replace them both, but its your money that will have to spend when just a little JB Weld would seal up the crack.
I would be thinking more about, if it has deformed the sealing surface for the gasket, thats why I was saying a good heavy coat of sealant on the gasket to fill any deformity.
Theres alway, V the crack, try to press the bulge back in shape & weld, but then you have to surface the gasket area back flat because the welding will push & pull the case.
