Truck and engine combos

Not sure, said it had the dyno over at cummins and it didn't pick it up. He hadn't looked at it since and said they'd fix it. There's gotta be a lot of things that need replaceing in a truck's life.. don't see why it can't be something that makes it idle sloppy until it is. They'll either get it right or they won't I guess. What I was wondering was if there is something about the ISX that makes EGR's go quite often, or if it is a stock issue thing that is replaced once and done with.

 

I am curious as well. Is it a every 500,000 mile repair or every 50,000 mile repair. I heard of the egr problem in the ISX. I drive a detroit.
Are you an owner operator now?

 

Just about. Authority is active but just finalizing the truck (I used another truck's VIN for the insurance in the meantime). It's been a headache. I really want this one to work out because it's a fantastic deal. They took 15k off a Pete 379 to get it within the finance company's restrictions for price age and mileage.

 

It wasn't the EGR. It's unexplained at this point, compression and injectors all check out.

Also it's a pete 387... don't know why I typed 379 up there. Also the shop said they don't know of any particular problem with EGR's and ISX's that they've seen.

 

Lt450 Please keep me posted on your truck search.

 

If I was buying my own truck I think I'd stay away from CAT. The problem with CAT is most of the time you can only get repaired at a CAT dealer and they are known for not fixing the problem right away. Their business is heavy construction equipment and the truck side of the house is just not a high priority for them. But of course it also depends on the area and if there's alot of construction going on. I was out in Las Vegas NV and we had to wait overnight sometimes for a small repair. That cost the company alot of money since they had to hire another company to pull the 12 loads that truck could have done.

We've had much better luck with Detroits and Cummins. And it didn't really matter which model. Sure some are better than others but time is money and for an O/O a full day for a simple part kills you.

 

Too bad they couldn't keep the Cunnims 444 around. You could do a Cunnims authorized Turbo switch along with a few other parts. It only boosted the motor to 450 but man could that truck pull the grades. It was great to go up a grade at 55mph when you used to pull it at 40mph.

We were empty one night and came along a side street. A fire truck was stopped at a red light on a surfuce street. They kept revin the engine and wanted to drag race. Of course it was 4am in the morning and nobody was around. Even if a cop did show up I'm sure he would have flagged us off the line. The race was on and we won. Of course we didn't do it very far but that truck was a mover.
