yeah that cummins is an awesome motor and like ive said around here its to bad ford can't have it but oh well

 

I don't think the 5.9 cummins can hold anything to powerstroke or a idi. I've got a F-800 with that sorry excuse for a motor it hard to start and it has alot of blow-by coming out the breather(only 80,000). wish I had a International 4700 with a DT466. That Cummins would do better as a boat anchor.

 

well idk but it sounds like somethings wrong there are millions of 5.9 cummins engines that are far more powerful at least for pulling the the v-8 powerstroke or idi. and all the ones that i worked w/ had no problems starting

if u want theres a site turbodieselregister.com that could help they are dodge guys w/ the 5.9 and they have seen it all and could help u if u don't want to pay to join id be willing to post for u so u can find some awnsers for ur problem. hard starting and excess blowby are not normal at all

 

Have the valves adjusted they need it aproximatley every 25,000 miles. Makes a huge difference in the way they run.

They still need adjustments, becuase they still use mechanical lifters.

 

idk about the amount of time in between adjustments but i do remeber hearing things about that they do need to be adjusted now and then

 

well i've keep it serviced every 5000 and i've ajusted the valves because my John Deeres have mechanical lifters just the same. i've had the ip and injectors out and tested there all good. It doesn't have as good of oil pressure. the timing is correct the idle is set right. I have have 22 diesels in my fleet. John Deere, Cat, IH, Detroit, Yanmar, and one cummins it runs the worst out of all of them with the most attention no hard feeling to y'all but i'm tired of it, gonna trade it soon for a International DT466

 

Leaving the common rail and second gen. HEUI trucks out of the equation, all Powerstrokes and most of the IDI's are significantly more powerful than the Cummins. The only diesel engine available with a lower factory HP rating than the Cummins was the 6.2/6.5 GM.

There's not anywhere near one million modified Cummins on the road, and that is the only way to pull a stock PSD or IDI.

As far as longevity is concerned....Find one shred of evidence that supports the theory than the Cummins is more durable than the Navistar engines. It's not going to be easy because it simply isn't true.

The only advantage the Cummins has it that it is less expensive to modify, but after you spend $3000-5000 on a used engine and Cummins/Ford swap kit, and another $500-2000 to get it more powerful than a stock PSD....what have you really saved?

 

Go Cookie88, you are on a roll, don't stop now.

I drive a Dodge Cummins company truck, 2000 5.9 six speed 80,000 miles on it..

I really like the parking brake and the six speed.

But I would not trade my 86 Ford 6.9 turbo 4 speed with 300,000 on it for it, the transmission and parking brake isn't that nice.
Power is about the same.
The Dodge rides smoother, but that is my fault.
I had to much fun at the spring shop and that Dodge will only haul about 1/3 the weight I haul on my Ford.
And I think my Ford steers much nicer.

MOPAR Micellaneous Obsolete Parts Assembled Recklessly

When you can show me a Dodge that has been through what my Ford has done for 20 years, I may listen to your story. But I do not think I will be listening any time soon.

 

you know they just shut down a thread that went off on this but i willing to do it again heres the deal i have an idi my dad has a 7.3 psd and my mom a cummins out of our three the cummins is by far better then the other too and that was before it was modified. that was also while pulling more weight. the psd may have more hp but because of the v design puts the power higher in the rpm band it is not as useable when towing as the cummins' inline desgin.



as for lasting longer idk of a psd yet that has made 100,000,000 miles or more there are several cummins owners that have been putting 300 to 400 miles a day on them and have reached anywhere from 700,000 to 1,000,000 and next to no shop time.



on the other hand i have an uncle who runs everything from the 6.9 to the 6.0 i belive he currently has at least one of every engine in his fleet. he uses them for pulling trailers loaded w/ tractors and other farming equipment he can't get more then about 250,000 miles out of them before they either go completly or are in the shop for expensive repairs so often they aren't profitable anymore. now i see comparision and say there is just no way that the ford psd motor is as durable and maintanece free as the cummins. now if you want more evidence look at the size of the internals and in paticular the con rods and crank shaft. on the cummins there are seven main bearings vs. 4 or 5 im not sure on the psd. the con rods have a whole journel to support the pressure of the pistion. the psd has narrower con rods in order to fit them all in this makes for more wear from the pressure on the journel. along w/ the rods and crank the rest of the internals are much beefier, more studs to clamp the heads on better.



modifications or cheap on mechanical motors only as soon as u get into the eclevtronics its expensive. so when u say its less expensive i saw its not. i turned up my idi for free and its making im guessing around 215 which is what the power of the late 97 98 cummins 12v w/ a 215hp p7100 bosch ip stock i got mine to that level for free yet since that cummins is mechanical it can also be turned up for just as much. its a matter of what controls the motor electronics or mechanical system

now for the benifits smiller i belive is useing a mechanical 5.9 replacing the old 6.9 in the truck w/ that hes gaining more power over the stock motor and for the price of truning the old one up to run w/ what a p pumped cummins w/ the stock plate slide all the way forward and maybe ground a little would run, this being all free i think he is out on top especilly if he gets a 215 version so to me it sounds like a hell of a deal

ihdiesel fan idk whats wrong w/ ur engine im sry ur disaponited w/ it and i hope the dt446 serves u very well i have heard good things about that engine

dave my mom has a 94 1ton cummins and a 5spd she pulls minimum of 8,000lbs and 80% of the time shes between 14 and 20k in its 200,000 mile life it has maybe 2000 miles w/o a trailer the truck was bone stock up to about 130,000 miles and then it only has a mild upgrade w/ some banks products the fail ip that was deemed a fluke by the techs was replaced under warrenty and the stock clutch finaly went after 160,000 miles thats been it never been to the shop for anything else, i change the oil and service it. the truck is not as old or gone as far as urs. but urs is over alot more time and im sure w/ a lot less abuse. and thats only one go to any dodge diesel site and talk to them about how loaded the are and how reliable. or talk to any of horse hauler that are for hire if they don't have an otr truck they use a dodge or switch to one soon after they get into the buisness. those who haven't say they have nothing but trouble w/ their fords and chevys. ya'll can listen to what i have to say or not i don't really care when my dodge reaches 1,000,000 miles on oem equipment and ur on ur 5th or 6th truck or motor we'll see whos is better.

and yes i know ya'll are gonna say why don't u go buy a dodge or something to that effect. well as soon as i get enough money i will. till then ill be around here so i can learn whats wrong w/ my engine and fix it

 

it's a cummins thats whats wrong with it. all other motors aside I can promise you the DT466 will last longer than any cummins. also before IH busted up the DT466 was in industrial pans and dozers plus in many tractors. After the split-up the DT466 went with the truck division, Dresser and Case had to put cummins in the machines and the cummins couldn't stand up to the stress of off road use.

 

Also here in North Carolina, theres alot of horses and all I see pulling horse trailers is idi's or psd's and the ocasional izuzu Duracrap.

 

That is completely incorrect in more ways than one.
Does an I6 BMW M3 have more lower rpm torque than a V8 F150?
A vehicles torque curve is completley independant of its configuration. Read my response in another thread.
2nd. You are predominately using the higher rpms when towing. An average diesel pickups rpms will be around 1900-2300 (this is an average of where the
engine will be spending most its time, depending on gearing of course). The Powerstrokes (and the IDI's) torque is the strongest in this range, where the majority of us use it.
If you want to start shunting rail carriages the Powerstroke (or the IDI) may not be as suitable, but for (the far more likely scenario of) towing a 10k lb trailer up a grade it is ideal.
First I will assume that the 100,000,000 is a typing error, as I don't know of any engine that will last that long (maybe a Yanmar diesel ticking at less than 500rpms)
I think thier are a few guys on here that have got some serious miles on thier PSD's - I can't remember how many though, but if it isn't 1million, its darn close.
Mine left my ownership with 140,000 of the hardest miles imaginable. It towed a 10k cattle trailer at 80-90mph (WOT) on mostly unsealed roads in 100+ heat. It didn't have an engine issue at all.
Anywhy its merely academic, as the odds on any of us (well me anyway) having a vehicle whose engine that lasts 1million miles is pretty remote. I work my trucks far to hard for that.
Apart from the head studs - which admittedly has caused a couple of stock 6.0l's to puke coolant, there is one reason why the Cummins internals are beefier. They NEED to be.
Navistars engineers aren't idiots, and if an engine needs to have 7 main bearings, they would use 7 main bearings. Thing is it doesn't - you may see this as a negative, I see it as a positive.
There are some of the users in here which place far more load on the engine internals than Navistars engineers could have ever envisaged, yet failures are VERY rare. Have you checked his gallery????
If there is a person on this planet that abuses thier truck. Mr Sponaugle would have to be writing an acceptance speech...
Honestly I couldn't care what you drive.
BUT, you must understand this is a Ford Enthusiasts site, and posting in a thread where someone enquired about how to go about replacing thier Ford engine with another Ford engine, and you suggest that he should use an engine from an entirely different manufacturer, as if it is the only engine that has ever existed you are going to encounter resistance.

You must understand the majority of us here have had nothing short of great experiences with our Ford trucks, and we will continue to do so irrespective of what you drive.

Some of us may agree that the Cummins has a good reliability reputation - me included - however I will never own one (irrespective of the fact that Dodge don't sell them here), purely because it will never suit what I am after in a diesel pickup (nor will it suit what the majority of the other FTE users here are after).

In summation:
I don't drive a Dodge, I don't have any desire too, if you have had good experiences with Dodges, or know people who have, great, it doesn't mean we all have to be driving a Ram.


After all this, I do sincerly apologise to the person who initiated this thread for hijacking it.

 

That was perhaps the most appropriate response imaginable for such a post. Thanks Bigf350

 

errrrr
so I guess the real question.

Smiller4597, since you are getting a cummins 5.9 will you mail me that peice of junk v8 6.9 international engine? I mean, it obviously isn't worth anything, least you could do is let my pay shipping to Georgia, where I'll use it as an irrigation pump, since it obviously wasn't much of a truck engine.

ohh, do you have a trans with it too? i've got a '77 f350 that would do nicely with a new 4speed.

thanks,
Drew

 

The DT 466 like all International engines don't have as good of top end as they should. the cummins engines i work on have either 500,000-900,000 miles on them with no major problems and they all start when its 5 degrees out with no either, no block heater, and no glow plugs. my idi won't start without being pluged in for at least 2 hours and cycle the glow plugs
