Engine Block Welding
Before you fire up your torch and begin welding an engine block crack, make sure that your solution won't add to the problem. In most cases--including the Cummins 5.9-liter with the number 53 cast on the drivers side of the block on engines built between 1999 and 2001--any electric or torch weld will do more damage than good--and it won't address the underlying issue.
Electric welding done below 1,200°F is unfortunately commonly applied to cracking problems, but cast iron simply cannot withstand the stress of this type of welding. The real damage comes from the fact that once you've welded this area and it fails, a better fix such as metal stitching can't be easily done. The area will have become too hard to be drilled or tapped with several additional new cracks and leaks.
