The international injectors have always had issues eather the injectors, o-rings or combination least the 7.3's did the fact is the higher the pressure the more likely lubrication is gonna be an effect if you compare the ~135 bar injectors to direction injection 1800 bar it's apples to oranges over 10x the pressure so i'm assuming that much smaller tolerance's so in effect the ulsd problem would most likely affect newer di engines not the tanks we love.
