How to repair a cracked engine block?
It is possible to weld cast iron using an arc welder and the proper welding rods, but that often can cause deformation to your engine block, or leave the welded area far more brittle and susceptible to further cracking. The other common attempt at fixing a cracked block is called cold metal stitching. This process is similar to sewing two pieces of fabric together, except it is far more difficult with metal. The main difficulty with this process is that it does not work well on components that experience drastic temperature changes as the temperature change causes swelling and shrinking of the metal which will cause the metal stitching to tear and the crack to reopen. This process is also often prohibitively expensive and only used on very large or expensive motors such as heavy equipment, diesel engines or marine motors.
How to seal a cracked radiator block?
The best way to seal a cracked block is to use BlueDevil Radiator and Block Sealer.

It is not a fibrous or particulate sealer that can harm or clog any other areas of your cooling system. Instead, BlueDevil Radiator and Block Sealer has a special chemical formula that will bond to the metal in your engine block at the leak point until the leak is completely sealed. The chemical weld formed by BlueDevil Radiator and Block Sealer will create a permanent seal that can expand and contract with the temperature changes in your engine. Since there is nothing harmful in BlueDevil Radiator and Block Sealer it can stay in your cooling system indefinitely sealing any future leaks your may have in your vehicle’s radiator or engine block.
