Dodge Cummins Engine Concern

[Furu]

By the way, the OP should know that you can check the original HOURS on that motor and compare the miles with engine Idle time. It's a Key on/off hold trip A type of check, but the hours are logged in the system module for that engine.

Sounds interesting. Can you go into a little more detail on how to do this and how to get the output result.

Just to clarify, Ford bought every 7.3 from Navistar.

And every 6.0 and every 6.4...
IIRC, most of the problems that Ford had with the 6.0 and 6.4 were not found on the Navistar versions of the same engines. The reason being that Ford used slightly different emissions equipment (EGR cooler for one) which caused many of their problems.

Hello Furu, Yes, I will....I'm bouncing around in my boat as much as I can this week, but I'll get the details from my truck and write it up. This might be helpful to buyers of used vehicles...especially when a used commercial vehicle with low miles becomes available. IMO, Lots of Idle time is not good for a diesel.

If I'm not mistaken ,, Cummins used / uses water cooled EGR on the 6.7

Hello PapaPerk, My Cummins has 92,000 on it. Funny, I too had the rear calipers seize up at around 50k if I remember correctly. The Carter Lift pump is around $125 bucks and very easy to swap out. I keep a spare in the truck tool box just in case, but it's not something to dwell on and I enjoy truck. The Dealer would replace the original lift pump if it failed and locate the new lift pump into the fuel tank. I didn't want them to modify or touch my truck so I kept it original. By the way, the OP should know that you can check the original HOURS on that motor and compare the miles with engine Idle time. It's a Key on/off hold trip A type of check, but the hours are logged in the system module for that engine.

Thanks for the info! What's your opinion on me replacing my pump as preventive maint?

Yeah I had around 60,000 when the calipers started dragging. They get a good salt bath in the winter .

All the manufactures had to deal with the same emission regs. they added nothing extra to ford/ navstar. others were able to deal with the regs better than Ford / navstar.. The new ford diesels are no better. My son is a medic and drives the Ford built diesel rescue trucks. He says the Fire Dept has already stated the next rescue trucks won't be a Fords due to the many problems they have had with their rescue trucks. I forget what he said it cost every time the truck goes to the shop to have the cab pulled just to work on the engine , but it isn't cheap.. Pull the cab just to work on the engine ????? Now that's a better Idea !!!!. The only good diesel that ford built was the 7.3...That 1 good engine hardly makes up for the many bad diesels ford made.... Like I said , I've owned many dodge cars/ trucks over my life ...Never a rust issue... If I had had the rust problems that many here mention, I wouldn't have owned as many Dodges as I have owned. I currently also own an 07 Toyota tundra... I haven't had any issued with the Toyota. I've own several Chevy / Dodge vehicles as service vehicles... No problems. As previously stated,,, I will never own another Ford , as 1 was plenty

I've heard of similar issues around here with the Ford EMS vehicles. Almost all of the vehicles have had their engines replaced at least once. Country I'm from switched to the kodiak style GM chassis and got away from the Fords.

The Ford 7.3 engine was made buy Navistar (IH). Ford Diesel engine can't be trusted. Only people around here that have Ford Diesels are the rich horse folk. Cause they have money to burn anyway! (0:

I'm waiting for a Toyota 1 ton with Diesel. That would be a sweet machine with a CAT, Cummins or Hino diesel in it! Still keeping my dodge cummins though! (0:

Are you guys talking about the lift pump on a common rail truck because I was only aware of it being an issues on the '98.5-2002 trucks

That's not a truck problem. Its a salt problem that happens to all brands.

Hi Firemanmike69,
The 98.5-2002/2nd generation 24V Cummins Ram utilized a VP44 pump and when the lift pump failed it failed in an expensive way. 2003 started the 3rd Generation, common rail engines. The filter mounted lift pump was a consistent weak spot in the fuel delivery but the failure did not create bigger issues to the repair. I believe, that by 2005 all the diesel rams had the fuel tank pumps.

Nissan Trucks are working with Cummins Diesel for an engine option in the Titan.

The early common rail Cummins, roughly 2003 to the early 2004 model years had the lift pump mounted to the back of the filter housing. They were not known for lasting long and were often moved to the later design, which was in the fuel tank, under warranty. That is what happened with my truck before I bought it. Should you replace it just for the sake of replacing it? I've never been a big fan of that but I would go with the in tank unit if you do.

So did moving the lift pump into the tank fix the common failure mode or does it just make it more difficult to replace when it fails.
From your statement if I understand it correctly, the 2006 came with the pump in the tank since it is the later design and not at the filter housing?

Yes having the pump in the tank made them last longer. I'm almost positive that your truck would have the pump in the tank. Yes, they are a ***** to change, you either have to drop the tank or lift the bed of the truck. People that have done it say its easier to lift the bed.

I've dropped the tank on my truck with only the tools I had with me before. not fun but not impossible. If you were at home it would not be that bad.

 

[mikehaugen]

I think the dealer will remove the bed instead of dropping the tank. They did on my dad's truck anyway.

 

[woodskiff]

The last few posters kinda confirm what I've heard from other folks also. I still like my stock lift pump setup...although, I once was caught up in all the hysterics and was going to change to a frame mounted, after market lift pump, with an inline filter, blaa, blaa, blaa. You know what?..I just drive it and enjoy it and stopped worrying about all that could happen.

Trust me brother I know ALL about that,finally went to a mechanical lift pump on my 2nd gen, thanks for the heads up about the early common rail trucks too

Really? My 1987 Chevy has the original calipers.

I just checked mine last night after I changed the oil. Turn the key to on (don't start it), make sure the odometer is showing the mileage not the trip mileage, push the button that would normally toggle to trip mileage but hold it down instead of releasing it like normal, hold for 5-10 seconds (can't remember exactly) and the engine hours will appear. I'm just under 2400 hours on mine.

Does that 1987 have disc rear brakes? I bet not. If it does, you're just plain lucky.
My 2004 GMC seizes up the rear calipers readily if not looked after. Salt damage is LOTS more prevalent in rear calipers than front.
