There wasn't a engine built from 2002 to 2016 that didn't have it's own unique set of issues
because of guinea pigging the market. Tossed on the public trying to find the clean end to
handle it. Below is the pile of ISX with it's garbage EGR system. There was one area many
a mechanic would scratch his head over with EGR issues. The plugged emulsion tubes, those
pack full of soot in no time, had to be cleaned every major service by running a piece of wire
through to unplug. Cummins said it was cold air on outside causing the plugging so Cummins
came out with a set of boots/covers to install--which did nothing.

I was working for a school bus company back in the late 2000's. They had two brand new Bluebird All Americans with the Cat C7 ACERT. Probably the worst imaginable application for a emmisions engine; putsy grandpa drivers, stop and go with plenty of idling. We very rarely had both buses running at the same time: one was always at Cat . . .

A pic of the engine compartment for everybodys entertainment. Almost as fun as a fire aparatus or motorhome . . .

Running what I brung and taking what I win
Like the DT466.

Owned several. Reliable engines but never in the powerhouse column. The ones I had were single axle trucks - 2 dumps and 1 flatbed. The newest one was a 2003 and all manual transmission - 6 Plus 1. The 2003 had a locking rear axle that damn near made it 4x4.

International makes the chassis and the engine and its line the engineers were pissed at each other and didn't talk, there's all sorts of stories of long repair times for simple jobs, bolts that be removed because they hit the frame etc.

I did a air governor on a m11 that took like 4 hours and my whole arm inside the truck. The other truck with the same chassis and a max force shot flames out the exhaust and fire around the turbo, that engine locked up

Is it economically feasable, to buy a Navistar with a trashed Maxxforce engine, then just replace the engine with , say a Cummins? Just wondering is the economics would make sense?

If it was really economical to swap it would have happened, but in most cases by the time
X amount of miles have gone by the truck is beyond it's life expectancy. No dealer wants
a IH on the lot especially one that has been converted.

No the electronics are not great.i ran I think a 06 with a m11 and it would go down and not start every once in awhile. The engine was deep in the chassis too to even do an air compressor was expensive. Maybe if it wasn't such as a tight design I guess and hook the computer up yourself, and guy the gauges and put your own.

I always see the same kind of truck as dump trucks and others, I'm sure they make a truck with more space under the hood.

Or cut the rear axles off and use those somewhere, and buy a pre 07 good brand truck and put your money into that.

Big trucks is what I know. HAZMAT is what I tow.

I’ve ran the numbers, and spent some bandwidth pondering that question, and no.

Somebody might have a solution. I couldn’t think of one.

Bandwidth? There's nothing to run, the IH has a sh---y cab, wiring and just plain sour design.
The best possible solution is blindfold it drag it out behind the barn and shoot it., then call the
local metal rendering plant to retrieve the carcass.
