If you don't trust ths "Seal the snot out of it" idea.

I have been repairing these cracks by drilling and tapping a cast iron "stitch" plug into the steam hole. Cut off flush with deck. Then drilling a slightly smaller steam hole in it. This completely seals the crack and leaves NO sealing problems
