ISX engines are great for people like me who do repair work when their not on the road, I think every company should own a couple thousand of em

 

I would be prepared to do an in-frame at around 750,000 miles. I have spoken to owner operators who have gotten more than a million miles on a Cummins before having to do an overhaul. It is all about the maintenance.

 

Can't speak to the ISX per se. My old truck had an ISM, the small bore little cousin. At 750,000 miles, it started to go all to hell. Kept having problems with injectors until they figured out it wasn't just one or two but all six that needed replacing. Then it broke a ring, the A/C compressor broke off, and a couple other things. It really needed an in-frame bad, but the company dodged that bullet by closing its doors instead. I limped along with that gimp for a few months, and then sayonora, no more job.

In contrast, my old old truck had... Dang. I keep forgetting what it was. NS-9? The one that came before the N14. It was an old mechanical engine, and we got every bit of 1.75 million miles on it, and that motor was still running, albeit not as well as she used to, when she went to the scrap heap. We were hauling light stuff, which helped, but that old truck did me right proud. I parked her before she finally gave up on me, barely. It was a near thing, but you can't fault a truck for being in nearly catastrophic need of a rebuild at pushing two million miles.

I'm a Cummins man. Driving an N14 now. I love that engine too.

 

I've got a ISX 500hp with 810000 miles on it right now. 13 speed 3.55 gears Runs great no major probles. I don't idel to much becouse I mostly come back home everynight. Or just shut off my truck when I stop. Only problem I've had was A/c compresser broke I changed that and the air dryer took a shit last year. It's a strong motor Them kittys wish whey could pull hills like this truck does. Cats are over rated just paying for a name on the parts. I had one for a few years nothing like this ISX motor.

 

Cummins removed the EGR valve from the hot side of the engine and placed it on the cool side which should eliminate most of the EGR issues. I think that took place in '05 or '06.

 

I think not idling would eliminate that too.

Everyone that bitches about the EGR valves on the ISX engines I always ask them how much they idle. "A lot"

Underhood gets hot as hell, and they have problems with EGR valves, alternators, hoses, etc..

Just wait until the new CAT engines, they're going to be even worse.

 

:roll: 500 cummins, a cat killer? lol...whatever dude

 

It's not hard to be a cat killer, especially when they're all broken down on the side of the road. :P

 

lol.....the newer ones maybe...I'll stick to my e-model. I've got a hard-on for a new studio w900l to replace my aerocab model...but the new motors have me running scared!

 

cummins out run my cat? :lol: theres a c15 in my KW and a 3406b in my wifes kw....


a cummins trying to outpull either of em is like bringing a knife to a gunfight. :lol:
