When is GM Going To Offer A Serious Diesel?

The overhauling statement may be correct. Cummins builds their engines with the intent to go a million miles with an overhaul every 300K miles or so. Navistar doesn't compete with Cummins in the class 8 market, so they don't have engines like the N14 (aka the old NTC Big Cam series), ISX, or Signature 600 to gain features and expertise from.

Navistar basically cannot be rebuilt, once its crashed, its junked out for good. I have yet to see anyone keep one and make one go up to the 300K mark. the most i have seen on any Navistar is about 220,000 on an earlier model engine, and it was on its last breath--but, i will say the owner drove that thing hammer down every where he went, i can honestly say no one could be harder on an engine than this guy.

my point is, I haven't seen anyone keep a diesel that long. Company i used to work for ran several powerstrokes in work trucks and traded them in when they hit 100,000 because everytime he kept one longer, it costed him more to fix it than it did to trade in for a new one.

This place is great. Seems like all you truckin men respect each other's likes and dislikes. I took a chance and bought a new Cummins 24v 99 because I liked my friend's 1994 12v. I hope I get as good service out of mine as he has out of his. We use the Gm diesels at work, hard to start sometimes, Have another friend who opted for the Ford Powerstroke, really likes it, but says fuel mileage can't touch the Cummins.
