A hotshotters Cummins stats

[dodge man]

I am also a member of a Cummins forum and there is a poster that is a hotshotter. His truck is a 2007 dually with a 5.9 Cummins in it. He just recently had to put in a rebuilt engine at little over 900,0000 miles. He was on his third set of injectors, he got something like 406,000 miles out of his first set. He is on his third transmission. What finally failed was an injector over fueled and fried one of his cylinders. I'm sure the engine could have been rebuilt but it was quicker to put in a reman. In the past he posted all the maintance work he has done to the truck. He was over a 120,000 miles before he had to fix anything, and that was a pinion seal.

Some truly amazing stats. Based on his engine hours, he has an average speed of 53 mile per hour. He has also averaged a little over 15 mpg out of this truck, of which about half were hauling RV's for delivery.

Here are the stats for his first engine.

Got the truck back.

Got the hours from the computer.

Hours on the old engine.. 17,002

Miles 904,313

Idle Hours 995.267

Idle Gallons used 974.21

Total fuel burned by truck 60,118.04 gallons.

I'm no expert, but it seems odd that over-fueling a cylinder would fry it. I don't know diesels well, but in a gas I would expect the opposite effect. Maybe a more knowledgeable person could explain this?

I agree impressive but the cummins is a very impressive engine, always has been. I use them in my power units anytime I can. The best I have heard out of the only comparable engine IMHO is about 700k with the 7.3L IH. Sorry but the new stuff does not even come close to the Dodge/Cummins. The jury is still our on the 6.7 Ford engine, 250-300k is the most I have seen so far. If I was shopping I would take a long hard look at the Dodge along with the Ford. CJ

Dodge man,


Thanks for posting this info, am awaiting numbers on MPG with the SCR Cummins.

Next truck will be a Dmax Sierra or a Ram Cummins,

You over fuel a diesel 1 of 3 things WILL happen. The cylinder will overheat, hydrolock or wash out. CJ

We had one with even better service history than that. This '03 3500 DRW 2wd went to ~840,000 before an injector washed a cylinder. The engine was otherwise unhurt, but he decided it was time and sold the truck in need of injectors. It had filled the crankcase with fuel and was spewing out the vent. With the oil level corrected and that injector shut off it ran great, other than the miss.

Had one set of replacement injectors, the front end if the engine resealed, one transmission rebuilt, one replaced, a set of rear axle seals, seat padding redone, a couple of minor electrical gremlins and that's it! He bought a low mileage '04 to replace it.

All this on an engine that is not built to the same standards of the old mechanical Cummins engines. The newer CR Cummins have lighter head and block castings. That being said they make ANY Powerstroke or Duramax look like a toy.

I've heard of an original internal hotshot 5.9 truck that had 1.7 million on it and still trucking. They are built tough as nails, with real solid Indiana engineering from high quality parts.

I have personally seen a million mile Cummins, Duramax, and 6.0 Ford. I have also seen a million mile 1/2 ton Chevy with a 350 that was on its 3rd motor.

What amazed me more than the miles was the shape all the trucks were in. To not get into a wreck at a million miles is the amazing part.

You can't think of diesels in terms of a gas engine, totally different. In this case CJONE has the things that happen when a diesel over fuels. In this case, it sounds like the body of the injector cracked badly and it over fueled that cylinder and caused a major problem in a very short amount of time. He had major blowby after he replaced that one injector.

In this guys log of repairs, at some point he was hit by a van and replaced a door and all or part of the bed of the truck.

Pretty impressive he got 120k without having to fix anything.

I dont know it the 2007's used different axles or u-joints, but I had to replace a rear DS joint @ 69k, and then front axle joints @ 75k. But mine is an 05.

Mom's 05/hemi also need a rear shaft joint @ 45k, and then wheel bearings and joints on the front @ 80k.

Still a great truck otherwise. And I like my 5.9:thumbsup:

What surprises me when I hear these types of numbers, is that they are not rusted out. Seems from the midwest east, rust is harder on vehicles that anything else(if generally kept in tune, oil change etc).

Kriwn rust control is your best friend!!

That terrible door chime they use now would keep me out of a new Ford.

I almost hate to admit this but my father in law has a 1/2 ton Dodge pickup with a 360 in it with over 600k miles. Original untouched engine, very very poorly maintained. Oil changes at 10-15k run low on oil quite a few times. Many transmissions. I rebuilt the frontend 3 times. Anyway I consider trucks like this the exception to the rule. Being in the oilfields we have all of the manufacturers diesels run to the limit on mileage and you get a good average as to what to expect for a engine. It seems that the idling is the hardest thing on these new diesels. But no matter what the manufactures say it is a fact of life for these trucks, if they can't do it they get replaced. I do agree it is amazing that so of these truck go so long without getting totaled out. CJ

Those old Dodge motors could not be killed. My BIL had a seamless gutter business. They had Gruman Aluminum trucks with Dodge 318's in them. Gutless as could be and dripped everything everywhere but you could not kill them.

He knew it was time to add oil when you went around a turn and the pressure dropped to zero. Most of the time it would not even register on the dip stick. He claimed it had been 3 years since he changed the filter, just keep adding oil.

A million times better than the what Gm used to have. I could not stand that thing blast out the left front speaker.

 

[Peacock]

I agree that one is annoying too, but I can't hear any GM door chime from across our shop.

Edit: I take that back. The chime on the Park Avenues and some other Buicks is quite loud.

It's the tone of the Ford that is grating to me more than anything.

Re: rust, assuming daily drive on a highway, here if you do absolutely nothing, a new car last about 10 years before rotting out. If you wash it regularly you can get about 12-13 years. If you undercoat every year with a good product you can get 15 years if you're lucky.

Cars that only drive in the city don't rot nearly as bad as the spray doesn't get forced into places. Quite common to find 15 year old city cars.

My 2001 super duty had nothing done, was a shop truck, the bed and cab have had body work done twice for perforation including new bedside, this year the bed is toast, all crossmembers have rotted out. Lower 6" of the doors will be done next year. Front bumper rusted through this spring.

i hate to hear about how the stuff up north rusts!! I love my older reliable vehicles. things ehre in the south run till malfunctions or to costly to repair, then usually someone who can fix it gets it and fixes it! I have a 1990 ranger with just a bit of rust starting to buble up on the rear quarter low near a tire, behind a metal inner fender area where i guess whateve could not get washed out.

Oh sure, rub it in why don't you. We actually go south to find cars/trucks that are not rusted. Just picked up a 02 buick with 60k on it an it looks new underneath! I would love to find a 99-06 ford 250/350single crew cab to throw my 01's drivetrain into. Truck has been washed after every snowstorm and it still is in ok shape but the box will have to be replaced soon. I HATE RUST. CJ
