Hi,
I have 05 QSM-11's. I had the local Cummins dealer do mine this year, (After Coolers, Heat X, Tran Coolers & Fuel Coolers) I also had to do the exhaust manifold gaskets - 2nd time. Not the best design from an engineering stand point, I have 'de-tuned' my props, but will most likely take a little more off next time I pull them. QSM-11 base engine is excellent, taken care of, 15,000 hours is not out of the realm of reality.
I have found my dealer to be easier to deal with then the factory branch.
