Putting things into perspective that you read on these boards where the tendency is to only discuss problems is important. That being said I definitely can get influenced by some of the negativity regarding the 6.0L motor be it explicit or not. I know I bought the coolant filter primarily because of what I read here and personal observation of silt/sand in my degas bottle. I had gotten wrapped around the quality control issue in that other manufacture's are able to produce a block with little or no residual casing sand left in the block. Kind of stupid on my part, it is there and needs (I think) to be dealt with. I think the most common problem resulting (correct me if I am wrong)seems to be oil cooler plugging and subsequent EGR cooler failure. My experience base with diesels comes from prior ownership of a Chevy 6.2L and since I am a submariner by trade, Navy diesel generators. In order to prevent "wet stacking" in the latter our procedures require that the engine be operated at something like 70 or 80% of rated load for a given amount of time prior to shutdown and that time is based on the time spent running unloaded. It seems the 6.4L has addressed the EGR valve issue by raising the operating torque of the actuating motor (by a factor of 5 if I remember right).
That is great what do I do with my 6.0L? It would be nice to have an interval that would make sense to pull the valve and clean/inspect or recommend an operating routine that would prevent valve sticking/binding on the exhaust side and on the EGR cooler note if it is truly a cause/effect of oil cooler plugging/EGR cooler failure then at a minimum require cooling system flushing at a sooner interval that 105,000 miles(I think that is what the book says).
I could be completely off base here but I would almost feel better with that kind of support from Ford than the 5yr/100K powertrain warranty.
