1999 to 2001 Cummins 5.9 Block Crack

You may be wondering why your Cummins 5.9-liter engine block has a crack in it after standard operational use. If your engine was built between the years of 1999 and 2001, you're not alone. Due to the technical nature of the original casting of this component, a vertical core shift occurred during the casting process of many of these engines. This led to an area that is thinner than the rest of the block wall and therefore the weakest spot on that side of the block.

Your engine is everything to your vehicle. That's why the technicians at LOCK-N-STITCH Inc. put their 30 years' experience in metal repair into finding a solution. They discovered that this complex original casting created an area with not only a thin wall, but also one that coolant has trouble reaching during warm-up.

Add these two issues together and you get a cracking issue that is not solvable by welding. LOCK-N-STITCH Inc. developed a solution that gets to the heart of the problem and that protects the spot for years to come. Their repair kit for the Cummins 5.9-liter engine block involves both metal stitching as well as a reinforcing bracket that gives the area extra strength.
