Somebody better not tell all of us that still drive an IDI 7.3 that it is a 100K mile motor, just as the true competition of that motor, ie GM and Ford BB gas motors were in MDT sized rigs, school buses etc. They do not get 250K miles generally speaking. THE T444E was designed to go around 400-500K before a rebuild, same as the previous I6 DT360, same size as a B5.9, and same longevity, but lighter in weight, so more payload for the end user.
The 6.6 dmax, Isuzu wanted it to be a 500K motor, but GM only wanted a 250K motor. If it had been designed to be a 500K as Isuzu wanted, you would have seen a few different HP versions for the NPR, NRR and Fxx series rigs vs the I4/6 versions they have and still are using.
Do not let all them train engines now that V-Motors are bad, and will not last......they do not run inline motors! They run V motors as they are more compact, fit into those rigs better, producing better hp/torque for them vs the I motors.

nobody said it was a 100k engine. International rates the engine as a B10(minor repairs) Life 200k and a B50(major overhaul) Life of 350K engine before a major failure. You should google the topic before you chime in

The in-line engine design has certain operating advantages, as do the V-shaped and the H-shaped and the round-shaped and whatever-shaped engine design out there. However, the design shape of the engine, per se, incorporates nothing magical about it that adds to its longevity.
I remember arguments about the 5.9 I-6 Cummins having a longer design life compared with the 7.3 V-8 International. Yet the manufacturers designed and built them for the same class of usage and the same predicted life before overhaul, and hundreds of thousands of 7.3s in school buses, medium trucks and pickups proved that, and they are still proving it to this day.

My point is your saying a V engine is only good for 250,000 miles. Obviously not correct, except maybe in cases of neglect. Your Cummins bias is showing here. ๐
