hmmm, do these guys really know what they are doing? or are they just replacing everything and getting chrysler to pay for it all? Injector seals can leak, but are easily fixed with a new seal. The injector pump normally leaks internally and fills the crankcase with diesel fuel - a good reason to check your oil frequently, but you would not see external signs of this type of failure from what I have read.
These engines commonly leak around the fuel filter, especially where a non-Mopar filter was used or if the clamps were not correct. I read a thread about a fuel tank leak, but that would show up around the fuel tank skid plate.
