Engine Block Crack Repair

Do you own a Cummins Diesel 5.9-liter engine manufactured between 1999 and 2001? If so, you may have experienced a crack in your engine block, even without carrying heavy loads or added horsepower. This crucial crack issue is one that many drivers and fleet owners have had to address due to thermal transfer issues relating to cold start-ups and not allowing the engine to warm up enough before driving away.

The cast iron repair technicians of LOCK-N-STITCH Inc. have brought more than 30 years' experience to the task of discovering the source and the best solution to this cracking issue on the Cummins Diesel 5.9-liter engine block. Their conclusion? The issue is a complex one that involves a core shift during the casting process that resulted in an area being thinner than the rest of the side wall of the block. Couple this with slow heat transfer to the lower end of the cylinders and you get sufficient strain to cause a crack in the outside wall of the block at the weakest spot.

This is why the crack develops not with heavy loads but upon warm-up of the engine. LOCK-N-STITCH Inc. has developed a patented repair solution that repairs the crack using strong metal stitching and reinforcement with a bracket designed just for the job. LOCK-N-STITCH Inc. is able to perform the repair for you, or provide you with the products and information to do it yourself.
