you guys and this "for cheap".....guess you dont understand the cost of all that equipment and experience.

not to sound like a greedy bitch but you'll need someone with a stick welder if its cast iron. clean it up real good with a grinder, and start welding 1/2" away from where the crack starts to ensure good heat up.

if i had a stick welder i'd say gimme 20$ and i'd do it. expect to pay at least that much.
