Actually Detroit diesel was not owned by GM, and was actually independent at the time, they are now owned by damlier/chrysler. and the duramax is built by Isuzu which is infact a wholly GM owned company.
And in reference to someone mentioning the Dana diffs used in ford not built by one of the big 3 but for the big 3 actually Dana is a division of Chrysler along with new process.
Ford, and dodge have never built thier own diesels with the exception of the 4 cyl diesel used in the 80s D50 dodge ram mini trucks which was built by mitsubishi a chrysler owned company, and that was a joke of an engine. (I better add that Ford never built an engine for use in a vehicle to be sold in the united states I don't actually know about the little 4 cyl diesels used in the rangers overseas)
most of hte components used on these vehicles are made by someone other than the company that sells the trucks, take the frames they are made for ford by a company in Iowa and sold to ford. Radiators for the most part are made by moline radiator (which does happen to be a ford company but sells to dodge, and chevie also), and I haul exhaust system parts for Tenneco/walker which used to be a GM company but is now independent, we haul parts for the GM cars, and truck as well as international, and volvo trucks, and Harley davidson, and also the exhaust used on your harley edition F series trucks are all made by this company. (actually had several pallets of the exhaust tips for the harley edition trucks on a load last week infact).
Now to further confuse the issue Tenneco doesn't build all of the mufflers that are used in these exhaust systems because I pick up several times a week at a Homer Donaldson plant to take mufflers to the plant that makes the system, and the hangers and flanges are made by canadian companies. this is the same company that makes the exhaust flanges for the ford vehicles we drive, the big 3 are so intertwined that it's actually hard to find were one stops, and the other starts
I was once asked when I was working as a mechanic for a chevy dealership (and drove my ford ranger to work everyday ) who makes the best vehicle? my response was none of htem they are all junk or I wouldn't have a job, and I still stand by that premise.

 

I've never owned either of the trucks in this thread, but I'm in or around them nearly every day of the week. All of them are fleet trucks and maintained regularly. I've seen zero problems with the PS and the Cummins. Same with the unmodified Duramax. One Chevy with a power tuner (or whatever) went to the shop a few times, but the problems were related to the tuner. I would buy a Ford if I was in the market, because of brand loyalty alone. The point can be argued all day long, but I see them all as being good trucks.

 

All I can say is Amen, Brother!

 

The majority of the people on this site would be out of a job if they weren't!!

 

I'm a die-hard Ford truck man and have been since the early 70s, and I'm glad to see that others are seeing the samethings I have said (on this fourm) and on the street, POWERSTROKES ARE JUNK. There was a time I thought I would buy a DURAMAX after further research there JUNK. I drive an 86 F250 4x4 with a 460 and I pull a 10,000# trailer and yes it is slow in the hills (5000-8500ft) anything over 65MPH is to fast for an F250 reg cab not enough wheelbase about 145" would help. THE POINT IS UNTIL FORD EITHER PUTS A CUMMINS IN OR BUILDS AN INLINE 6 CYL.DIESEL you powerstrokes can outrun me loaded, empty I'll eat you for lunch, but when all is said my wallet will have more money in it even at 6-7MPG towing. My repair costs are near nothing.

 

I'd take a powerstroke over a cummins for a truck any day, if i want a cummins, i'd be driving a 379 Perterbuilt. The cummins is a good engine but i don't know how dodge can make it so loud, considering in tractors, they're quiet.

 

Guys/gals - remember no need for brand bashing

Have you heard a Cummins 600 (the current Cummins in the Dodge)?
I doubt it - because you can't, its darn quiet...

The PSD is the actually the loudest of the diesels now, but I happen to like the sound of it personally.

 

That's fact. I drove a '06 D-Max yesterday- it's almost too quiet. I like hearing the turbo spool up on the PSD.

 

You and me both.

One of the advantages of getting an F-350 in Australia is that it comes with a single 4" stack from the factory - all vehicles over 4500kg (4.5tonnes) GVWR must have a vertical exhaust.

I love the sound upon planting my foot at 50mph - in 6th with a trailer behind - and just listen to it slowly wind up.

 

If it was a dmax the wind up wouldn't be so slow. lol just picking

 

That's a pretty bold statement. Please explain in great detail why the Powerstroke and Duramax are "JUNK". Please don't just compare them to Cummins, give us FACTS that prove these two engines to be "JUNK". There are a lot of people that come on this thread looking for advice on which diesel truck they should buy, so what you know about these two engines could be very helpful.

 

Man I am gonna go along MofW on this please tell us why they are junk without using the cummins as a comparison.
I don't personally like the 6.0 psd, or the duramax for some reasons I will outline a little later in this post but I didn't just use a blanket statement like that so if you have specific research please fills us in so anyone looking can understand what you mean.
My specific dislikes are as follows duramax personally I don't like alum heads on a diesel although so far this hasn't been a problem of any great extent like I originally figured it would be it's just a dislike, not of the alum heads as I run them on my race engine but on diesels I don't like them. Also on the duramax and this comes from talking to a lot fo owners of them, and talking to a couple of fleet owners with 20-35 trucks each, and it seems to be a crapshoot on them for power and performance with them you will have one that is the best performing thiing you've ever driven, and the next one won't pull itself out of a wet paper bag and gets terrible mileage. of the fleet owners I talked to had 25 of them all the trucks were setup identically since they ordered them all at the exact same time, and infact I believe something like 12 of them were sequential serial numbers he said a certian portion of them were super powerful, got great mileage, and had no problems whatso ever, then there was a few of them that were just average, but there was 8 of them that would bog down pulling an empty trailer and cut the fuel economy in half with that empty trailer, and they weren't getting all that good to start with in relationship to the others. and GM couldn't find anything wrong or different with them.

6.0 psd I researched them when I thought about trading my 2000 off, and talked to my wifes nephew who works on them for a living and it was his feeling that they weren't built very well, and after he talked to one of the engineers that helped in the designing he learned that they were built to be a throw away engine, and were produced to reduce production costs as much as possible the heck with reliability things like cyl walls are thin, they used hypereautic pistons instead of forged, basically everything in them was the cheapest parts (you know kinda like the space shuttle 2 miilion moving parts built by the lowest bidder instead of hte lowest with the best part) plus with the original toothing pains of knocking the injectors out I have been very leary since then. now beyond what I talked to him about and the other problems I have found them to have by reading on here I can't give real specifics, other than to say when Ford only keeps an engine in it's lineup for a couple of years there is usually some problem that they don't talk about and a 4 yr run is pretty short. and the fact that is was only out 2 yrs before they annnounced that it would be replaced in 07 makes me doubly suspicous I am just hoping that they do a lot more testing before they release the next one, cause they didn't do nearly enough on the 6.0

 

Fact: The 6.0L Powerstroke had trouble when it first came out.
Fact: Those teething problems are now fixed, and the engine is reliable.

Fact: The Duramax had troubles when it first came out.
Fact: Those teething problems are now fixed, and the engine is reliable.

Fact: The Duramax and 6.0L Powerstroke are good engines (now).
Fact: The Cummins and the old 7.3L Powerstroke are better engines.

Definition of better in this post's context:
Better : (bet-ur) adj. : Able to do everything the other engines can do and do it for 300,000 miles with no major repairs and decent maintenance due to the strength and ruggedness of the fundamental design.

 

Why one person thinks the 6.0 is junk and the Cummins is better proves to me that opinion is more important than fact on this board.
My proof.

Opinion
PM rods are garbage
Fact
The PM rods in our test 6.0 survive cylinder pressures that blow the heads off the block. Shortly, most performance rods will be PM

Opinion
The boost pressure that a cummins can handle means it is a tougher engine

Fact
The real measure is actual cylinder pressure.

Opinion
The I-6 is a stronger design
Fact
The I-6's weakness is the very long crankshaft "twist" and intake manifold design. The block is cast thick to handle the imbalance. The V-8 has two rods per throw but only one is firing at a given time.

My opinion
The Cummins has a lot more aftermarket support, that is why it enjoys the success that it does. The 6.0 is a new engine.

To finish
As a test to the "experts" on this board, what is the I-6 imbalance that is inherent in all inline engines and where is the nodal point for the 2nd degree harmonics. Also, as a locomotive engineer I can tell you that almost all locomotives built are V-16's and V-20's. for a reason. None are Inline.

Pay close attention to the answers readers and You will see what I mean

No offence to anyone but the truth is important
