I guess no one reads my entries much. If there are any other lucky people to own a Mack with a 565 Cummins engine, good luck. Cummins must have decided not to do alot of R&D when they came up with this motor. My reasons are simple, EGR cooler is poorly designed and destined to fail, Turbo also has a high failure rate, EGR valve same story and for the last, let me add the head in all of this mess. Much like most things, everything fails just after the warranty has ended. The only thing Cummins did for us was to take 50% of the price on the head and some labor. As I am typing this, my truck is in the shop once more for another EGR valve and poor mileage. The only good thing this time, the stupid valve is still under warranty. Whoppie!
