Fix Cracked Diesel Engine

If you're faced with having to fix a cracked diesel engine, you're well advised to do your research first. If your engine is a Cummins 5.9-liter model built between 1999 and 2001, you may be looking at a crack that other owners have experienced as well. On the lower front portion of the engine block of the driver's side, you will find the number 53 cast in the block just above the oil pan.

The cause of this crack is complex. When this Cummins Diesel engine block was cast, a slight core shift caused one area of the wall to be thinner than the rest. This translates into trouble when a driver takes off before fully warming the engine after a cold start. Coolant is used in the engine to transfer heat from combustion to the radiator, where it is transferred to the air as it passes through. Coolant also transfers heat to all other areas that are not directly heated by combustion. Eventually, the entire engine is at near the same temperature. Increase in temperature causes an increase in thermal growth of the cast iron. Uneven thermal growth causes strain that can crack the cast iron because it cannot stretch. It simply cracks to relieve strain.

The crack occurs at the weakest spot on the side of the block, and it requires a fix with enough strength to withstand the uneven thermal growth.
