Which is a better diesel engine in terms of durablility and longevity, 2005 Powerstroke or 2005 Cummins 610?

Ford claims it is the longest lasting diesel w/ a life expectancy of 250,000 miles while Cummins has a life of 350,000 miles

Any info will be helpful,

My gut would say that the Cummins would last longer because of the following

1] 7 main bearings
2] lower rpm band
3] 30 % less moving parts
4] One rod per a throw on the crankshaft
5] better angle on rod in power and compression stroke
6] more mechanical advantage because of longer stroke

But really I would say the driver has more to do with how long a motor will last.

 

Haha, man, there has to be one of these questions at least once a week, I tell ya.

 

I wouldn't put too much into those longevity claims. Its how you will treat it. My GAS V10 has 210,000 miles and is still like new. Im sure both of these engines will last at least 400k, but as to which one's electronic sensors, turbos, egr, injectors, etc. will go first, im not sure. We had a 6.0, now a 05 cummins 610. I think the 6.0 is better for day to day driving, but i prefer the cummins for long highway drives.

 

I think the life of an engine is determined more by how they are driven and maintained than how they are designed. I've seen well designed engines die quick and poorly designed engines last for ever. There are to many variables to say for sure which will last longer.

 

From my limited diesel experience in marine applications, in-line motors have significantly longer lifespans than v-block motors. Something about how over a long period of time the cylinders in V motors tend to become oval due to the effects of gravity. So it would seem plausible the Cummins would have a longer life-span, although the rest of the truck is another issue entirely. Again this would all be based on the driving conditions and how well the motor is maintained.

 

Thanks...Good work!

I guess I will have to maintain my PS 6.0 well and see what happens

Cummins or no cummins I would rather have a Ford truck any day off the week. The engine might last but the truck sure wont. I am really amazed how Fords picked on by everyone else especially the Dodge guys. Hey Fordguy you got the best truck on the road.Enjoy

 

What about a Fummins?

There are reports of 5.9 cummins in the 1.2-1.4 million mile range without lifting the head. It is a very durable engine.

 

Cummins - no doubt...
You might get a differant response if you would'a asked 7.3 vs Cummins

 

Thats for sure...I would take a 7.3 over the Cummins any day of the week.

Cylinders turn oval due to the effects of gravity??? This doesnt make sense, unless you were continuelly running the engine so hot that the metal could warp, but even at that, the engine would be dead long before this could take place. Check out the old Flathead V8, or any other V8 from yrs ago, have you ever seen the cylinders turn oval??

 

Dude, don't even try............I have and this urban myth keeps popping up like a bad case of herpes....it just won't die.


Some people somehow think an inline motor's pistons go straight up and down as if by magic.........No rods to exert side load while going up or down.

Using the gravity logic I cannot believe how Boxer (horizontally opposed)motors don't just wear a hole straight out the bottom.

Then the same people will compare low revving Inline motors to higher revving V8's and proclaim this great longevity advantage.

 

All engines wear the cylinder lining. The Cummins is good in-line engine. Same for the V8 PowerStrokes no matter if you like the 7.3L or 6.0L

When you purchase a vehicle you looking at the truck as a whole unit. I rebuilt a Deutz diesel at 15 thousand hours that saw severe use everyday. One of the Cat tow motors at work is 1.5 yrs old and has 10 thousand hours on it.

Maybe someone should offer John Deere, Deutz or Cat in the engine line-up for trucks.

 

My father has a Deutz tractor with 13,500hrs on it. It hasn't had a problem, beyond the AC compressor going south, and wearing through 3 clutches.

I am mightily impressed with it. The only onther tractor he has had that has lasted that long is a Fiat (go figure).

 

I'm glad I'm not the only one that noticed that.
I love that "...wear holes straight out the bottom" and "...keeps popping up like a bad case of herpes...it just wont die" LMFAO
