Can this be repaired?

Don,t take it to just anybody,plus you need to make sure you drill the very end of the crack then slightly v it out not much then apply filler material(rod)also area needs to be clean and free of oil,preheating with a large torch tip should take care of it,do not concentrate flame in one place slowly move it around area,after welding wrap it with an old welding jacket or cover with leather gloves allow it to cool slowly,after you can carefully tap it,Good luck,Sid.
