These International engines can be difficult to diagnose without the proper tools; namely Ford's I.D.S., or Navistar's DLC.
As for the o-ring the dealer was hinting at, they may have meant the o-ring on the fuel injection pressure regulator. I have witnessed these leak and cause difficult or no starting. This component is located at the rear of the engine below the turbo exhaust supply tubes. A specialty socket is needed to replace it (35mm 12 point socket which resembles an O2 sensor socket), although replacement is most likely unnecessary considering that your vehicle does eventually start. If this were indeed the culprit, your engine would not start. There is a test port next to this regulator to test oil pressure (bolt with allen head relief). A high pressure gauge which reads greater than 5,000 psi is necessary to test at this port. When your engine doesn't start, try checking what the oil pressure is at this port. A minimum of 3,000 psi is needed for the engine to start and 5,000 psi is prefered
Other sources of this problem could be the intake air temperature sensor, oil temperature sensor, or wiring compromises. It's a shame the dealer didn't want to spend the time necessary to pinpoint your problem. So glad I'm out of that crooked industry.

you need to have the engine coolant switch
checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the
computer will make it a rich or lean mixture to start the engine,if it tells the
computer that it is 75 degrees the computer will lean the mixture like starting
a car in the winter without a choke.
