#30 or a 3mm bit, drill through right at the end of the crack. You can use 24hrs epoxy on the hole, lay it on the side so gravity will draw the epoxy into the crack, use tape so it does not dribble out and onto the work bench. Epoxy will help ward against it separating from the casting, the hole will hep to stop the crack from progressing...
