How are they determining it has fuel in the oil? Is the oil level overfilled? Did they have the oil tested at a lab (Blackstone, etc.)? The reason I ask is because gas engine oil doesn't ever smell like gas unless there's a problem. Diesel oil always smells a little like Diesel fuel, and to someone who doesn't know much about Diesels its an easy mistake to make. Now, if it reeks of fuel then there's an issue.
Are they torquing the injectors down with the right spec? Ford revised the torque spec for the earlier T40 sized injector bolts to prevent them loosening. The injectors sit in fuel, so if one comes loose its fairly easy to leak a little fuel. There's 40-60psi worth of fuel against that lower seal all the time, so it doesn't take much for it to blow past the o-ring.
I don't know if a crack through one of the injector bores in one of the heads would do this. Typically that results in fuel in the coolant. Heads do have all three fluids flowing through them though (oil, coolant, and fuel) so there's always the possibility of cross contamination if something is wrong.
