cummins and dodge will work through these problems the same way they did for the 53 block,lift pump and vp44.
I didn't own a 53 block but have never heard of one that failed within 100k mile warranty that Dodge or Cummins didn't step up to the plate for.
I put 325,000 miles on an '01 HO/6 speed. The first VP-44 injection pump was mistakenly replaced at around 135k miles but when my mechanic buddy and I realized the original was not the cause of the problem I was experiencing, the take off pump was sold to another Dodge owner and is still in use today. The Cummins rebuilt VP44 we installed is still running great at 342k miles in the '01 although I no longer own it.
Dodge replaced the original lift pump in my '01 at 62k miles under warranty. I replaced one more somewhere around 150k to 200k miles just to avoid a failure on the road. The third one is still in the truck at 342k miles and works great.
I know this is a controversial statement I'm going to make but I have experienced VERY FEW problems with either of my previous Rams. I don't understand why some replace so many injection pumps, transfer pumps, or injectors.
I just retired my '06 Ram yesterday with 228k miles on the odometer. It has all six original injectors in it and when an engine diagnostic was run by a dealer a few months ago all were normal.
I remain a loyal fan of both Dodge and Cummins. I love their products and have found them to be extremely reliable in over 550,000 miles of road use, mostly towing, since early '01. I just bought my third one yesterday.
