Jonas,
I bought a new 84 F250 with the 6.9 and it ran great. I had the C6 behind it and consistently got near 20 mpg. As previously stated I replaced the glow plugs several times over 12 years. Also the injector pump went at about 100,000. Otherwise a good engine. As far as why did Ford replace them with the 7.3 and now 6.0? Kind of a silly question if you applied the same school of thought to the old Model T 4 bangers! Happy fourth of July.
