I don't know if you have a 53 block or not. If you do, you are another one of the many unlucky. I too am in this group,however, my block on my 99 has not cracked YET! I don't know if it will or not but it has a better than most chance because I tow heavy, I bought the truck to TOW, if I didn't want to TOW the loads of farm equipment I pull on my 5'er, I would have stayed with the many gas GM's I have owned. It has been posted on some threads that if one loads too heavy and their block cracks that they should'nt b... h about it. I don't see it that way because the weight of the tow should have NOTHING to do with whether the block cracks or not. Maybe other things such as the transmission,rear end, clutch, U joints etc. but NOT THE BLOCK!!! It has been said that Dodge buys the engines from Cummins without warranty and I also understand that but there is a law that goes beyond the normal warranty as it is often thought of and that is the WARRANTY OF MERCHANTABILITY AND FITTNESS OF PURPOSE. I think this is where a KNOWN DEFECT by a manufacturer (Cummins) has some if not all of the liability. But I'm not a lawyer, and it would take a Class action lawsuit and many years of legal fighting to resolve. I just find it unacceptable to pass this defect off and all the potential cracked blocks that will happen in the future, by merely saying that if you are out of warranty you are SOL given the track record of long life for these engines ( up to and beyond 1,000,000 miles for some). Cummins and/or Dodge SHOULD cover just the cracked blocks for years to come regardless of miles or age because IT IS AND WAS A KNOWN DEFECT!!!
