After reading that, I'm freggin exausted. I forgot what the original question was. I dont care what it is you drive, if you you beat on it it will fail, period. If driving it hard means taking it out and blowing the cobwebs out once in a while within the reasonable specs of the vehicle, go for it. Diesel engines want to be run, but within reason. A diesel will run around the world many times without stopping at an rpm of 2000 but step that up to 3000 your asking for problems.
Which leads to this question... BLK94F150, did (do) those 6.0 ambulances have the high idle conversion installed? You said yourself, they spend a whole lot of time idling. I'm not trying to be smart here, I seriously wonder if they do, and if not could it help with some of the problems they're having.
Aside from that, Bowie, surely your uncle would tell you if he's had problems with the truck, and if so what and why, and how it's been maintained and driven. Assuming you trust him to be honest with you about that, I think I'd let that be the biggest guide to my decision. So far I love my 6.0, but I've only had it 3 months and 5000 of it's 62000 miles, so I don't feel qualified to say much about it's reliability yet, except that I'd feel comfortable to go out and get in it right now and drive it anywhere. If you've learned all you can about the truck, and spent enough time in it to feel that way about it, then I'd say go for it.
That would set off alot of codes and make the engine run awful.
The solution your after is the high idle conversion kit. Look for it in the 6.0 forums they'll lead you right to it.
it actually does not set off codes or cause the motor to run awful, at least not on my 03 because i've got mine un plugged, i will look into the high idle mod though
Since this is the diesel discussion and running it hard seems to be the thread I'll just comment on diesels as used in off road, such as tractors. I know of a couple new diesel tractors where they wet stacked and or use oil. The repair was to put them on a dyno for a couple hours under heavy load. This serves to seat the rings or whatever, break the engine in correctly. End of problems both cases.....Kinda like running it hard. Don't get me wrong, I do not condone equipment abuse at all. But, I do believe you have to load one, use it for what it was intended. Loafing around may or may not hurt it.
And FWIW, I've owned a Navstar 7.3, good engine, a Cummins 8.3, another good engine, a Ford 172 CID industrial, another good engine, a five cyl Volvo in a passenger car, another good engine, and a Yanmar in a John Deere tractor, another good engine. Sounds like someone on here needs to learn a little tolerance of others opinions and experiences.
thanks for listenin',
