View Full Version : Diesel Engine Longivity

I need to upgrade my truck, business is booming, and have had to wheel barrow:weightlifter: tooooooo much dirt, rocks, and pavers because I can't tow the weight of a bobcat to make the job easier and quicker. I have been looking into a few pre-owned 2500 and 3500 Diesel trucks, and saw a Ford F-350 with 72,000 miles and they want $26,000 before I work my magic and talkem down some. I also looked at a Chevy 3500, 4X4 RED, Nice with 112,000 miles and they want $22,000. Should I keep looking and jump on one of these trucks...also the ford is loaded, SunRoof, lther, etc....with the matching camper thats custom and mold right in with the truck. I need some help and advice.

The 6.0L PowerStroke has been rated a service life of 250,000 miles by International. Of course, this is not a warranty but an estimate of the engine's life span when properly maintained before a major overhaul. In other words, most diesels when well maintained will outlast most other parts of the truck (transmission, etc.).:)

I am selling a 2001 ford f350 3-4 yd dump with only 41000 mile, 4x4, plow, etc for only $17,500 obo

You're gonna get many opinions on this.

Engine longevity depends on many things including how it is driven, idled, maintained, and treated. Buying used is a crapshoot many times.

Engine wise...they're are all at least OK. The older Ford 7.3 pre-2003.5 were good engines. The newer 6.0 PSD has been very problematic. Many problems have been fixed for 2005+, but visiting thedieselstop still reveals many problems. The Duramax had some injector problems for 2001-2002, and some problems with overheating exists in some. The Cummins has remained pretty much the same for 15 years except for some slight changes. It is also the only engine of the three rated medium duty by the EPA. It's average overhaul life is a minimum 300k miles.

I don't own any of them, but plan on buying one this winter. If buying new, buy before the new EPA restrictions go into effect for the 2007 model year. When I buy, I'm only looking at a Dodge or GM for new, and used would be GM 2003+, Dodge, or Ford pre 2003.5/7.3 PSD.

Also remember each have their own problems otherwise. Ford and Dodge transmissions are pretty crappy until the 2003 model year for both. The new Dodge 48re has been much better, has been the Ford Torqueshift. The GM Allison has the lead right now.

Good luck. Visit sites for all, there are MANY out there.

If you want a good truck the oney way to go is with a stick shift. The Kills the GM but i konw the 6 speed ford with the 7.3 PSD will last.

That sounds like a lot of money for a truck with that kind of mileage, even if it is a diesel. Sometimes it is better to wait because if you jump on the first thing you see something better will come along and you will kick yourself later. Go to nada.com and look up the values of the trucks, it will help. Just my .02:)

I know that a diesel will last long, but with propper care, i've seen gas engines with 250,000 miles on them and stil kicking.

08-13-2006, 07:01 PM
i know its not the same size but of all the diesels in pick up trucks whats the one that is also in a lot of over the road trucks...CUMMINS. so go buy a dodge and youll have no problems with power, longevity, and fuel mileage

I have a 99 Powerstroke 6 spd with 315K and it still runs and pulls like new. Great truck.

08-14-2006, 12:37 AM
As a sideline business, I buy and resell Powerstroke Ford pickups during the fall and winter months. I buy from a fleet, and all the trucks have over 225,000 miles on them when I get them. I am friends with many of the folks I sell them to, and some of those trucks now have over 300,000 miles on them. They are still running great. All are the pre 2003 Powerstrokes. I will not be buying any of those 6.0 dogs. Too much risk involved with those engines.

Most people in this area won't touch a used diesel P/U truck if its got more than 200,000kms (125,000 miles) on it because the engine will kill you in the price of parts.

A reman starter for a diesel P/U is minimum 400 dollars, Glow plugs are another 30 dollars each,CPS for a PSD is 300 dollars, lift pump for a pre 99 PSD is another 250 dollars. I bought a serpentine belt for my 95 PSD it cost me around 90 dollars. If you have a 5spd a LUK single mass clutch is 2000 dollars to replace a factory DMF set up is 2500 dollars. To buy a complete drop in PSD your looking at 8000 dollars tax included. Oil changes on a diesel isn't cheap expect to pay 30 dollars for a oil filter another 70 dollars for oil. Replace the fuel filter on a 95 PSD another 50 dollars.

A truck with 200,000kms (125,000 miles) usually needs work it will probably need a complete brake job 2000.00 if the truck has a automatic it needs a rebuilt so 4000 dollars. Most 5spds manual transmissions need a rebuild after 200,000kms so plan on 2500 dollars for that. The clutch is got to be done so add that cost in. If the truck has pulled a heavy trailer the rear axle will need to be done another 1800 dollars.

We have a thing called rust so usually the truck is rusted and needs work. If your lucky the previous owner put new rubber on it if not to reshod a dually with Michelins your looking at 1700 dollars.

The only way I would buy a truck with 200,000kms would be if I knew the history of the engine and cross my fingers. Maybe the engine itself will go high mileage but the parts on the engine forget it. If you have injector problems on any of the electronic engines its going to cost you big time. A friend of the familly had to have the oil pan replaced on his 2000 F-450 PSD cost 2600 dollars it was rusted through.

The old Chevy 6.5s you could mark on the calender when the IP pump would fail. Alot of Chevy 6.5s needed engine replacement every 250,000kms (155,000 miles). I know of a Chevy Tow truck its got 450,000kms (280,000 miles) its on its 3rd 6.5 engine at 6000 dollars each.

Most guys that buy new diesel trucks run them till the warrenty runs out and trade them in on a new one. The 03 6.0 owners if they didn't have warrenty it would cost more to repair the truck than buy a new 05.

When guys buy diesel trucks around here its because they want one or want more power. Keeping a truck for 300,000kms (187,000 miles) is far far from their mind. As for fuel savings paying for the engine never ever happens a truck doesn't last long enough to recover the savings.

Right now we are paying 4.25 a gallon CND funds for diesel fuel so 3.80 US funds for gallon of diesel. Regular gasoline is 4.40 a gal CND or 3.92 US for gallon of reg gas.

If you really figure you buy a used diesel truck for 20,000 dollars expect to spend another 5000 to 10,000 in repairs in the next 4 years of ownership.

You can buy a brandnew 06 Diesel Ford-Dodge or Chevy for 45,000-50,000 dollars run it 4 years and trade it in on a new one. A V-10 powered truck is 35,000-40,000 depending on how its spec'ed. A V-10 Powered truck will go the same amount of reliable miles but it will burn a little more fuel. A V-10 will easily go 250,000kms a diesel will go the same but it probably cost you another 1000 dollars in parts where as the V-10 would be 500 dollars.

The argument that a diesel holds its value better what is the point if a high kilometer diesel P/U sits on a lot getting lot rot. You will never regain the 7000 extra dollars you spent to have your PSD or Cummins or extra 10,000 for your Duramax/Ali combination.

The big difference on durability is where the truck spends most of its life. When your driving on 10% grades pulling heavy loads on 10% grades and the engine is working hard is no comparision to what you flat landers call a steep hill what is that 3% grade :laugh:

The flat landers can drive for miles and miles without turning the steering wheel. You really don't know what pulling a steep grade is all about.

Take for instance I can buy a truck from Alberta or Saskatchewan Canada both prarrie country where its flat as a table top. The truck could have high kilometers but its never seen a hard life the same truck West of the rockies with the same mileage is a worn out POS.

To sum it up buy the lowest mileage diesel you can find leave those high mileage trucks on the lot they are not worth buying. You crunch the numbers they will cost you more in the long run.

Gravel rat, I know you know what you are talkin about when it comes to trucks but your prices there arent even close man... maybe you are giving CND funds which are more than we pay or something.

Oil change on my cummins: 3 gallons oil: 25$ 1 fleetguard filter: 12.95 That is it, 40 dollars, not 100.

Auto tranny rebuild could be anywhere from 1500 to 4000 for a new unit.

Reman starters are nowhere near 400$ This site has them listed new for just above 100$ http://www.newircusers.com/store/ir10_33576_Starters_&_Parts.jsp

So parts on a diesel are not as bad as people think. Glowplugs, 50 for 8.

Friggin LUK clutch aint gonna be no 2k, maybe 900 or so, I would go with a con OFE though around 1300$

I agree with your statements on pulling grades VS flatlanders and such. JMO used diesels with 150,000+ are fine in my book.

you better be sending a couple of them up my way

Funny you should say that. The last one I bought, and have kept to use in my "fleet" this summer, came from Washington, Pa. I had to have it shipped down to me. This is the first one I have brought down from the 'Salt Belt". It has a rust issue with the bottom of the driver's door, but other than that, is pretty clean. It is a 99, F250, ext. cab, longbed, XL trim. Came with all the maint. records since new. All trucks I buy come with the records, so the high mileage does not concern me.
If you need a good F250 extended cab, or an F350 crewcab truck, this fall or winter, send me a PM, and I will find a good one for you. Depending on the year, model, and miles, I usually sell them for under $9,000.00.

Gravel Rat, you would save a fortune on Maintenance if you simply stopped buying powerstrokes :)

The prices I quoted are CND and thats what it costs us to repair our trucks its why it usually cheaper for us to buy a new truck. With the CND dollar being as high it is now it can be just as cheap for us to go to the US buy a brand new truck and bring it back.

I have found 06 F-550 4x4 diesel with a 11' dump box for 48,000 dollars US approx that comes to 53,000 CND. A F-550 here with the same spec's would be a easy 56,000 dollars or more. The only problem is the US gov't makes it tough to export a truck out of the US and the CND gov't wants their tax money off of it. If it wasn't such a PITA to import a truck to here I would have bought a rust free truck from California long ago.

There is no way a light truck is going to last 300,000kms (187,000kms) without constantly replacing parts. It doesn't matter which brand Ford Chev or Dodge once they get to a certain age you can pretty much count on spending atleast 200 dollars a month in repairs.

08-15-2006, 09:52 PM
Figured it was CND but I still get your point about stuff breaking on diesels and the fact that a high pressure common rail injector is about 300$ more than the injectors on a V8

I have had them all...and enjoyed them all! They all have their pluses and negatives....PM if you want feedback on them.

Cummins diesel tried and true. Dodge makes the crappiest cars in the world. I have replaced so many heads on Dodge Decrepids that I can't count them. However, the Cummins diesel has been around for a long time and the bugs are worked out. Right now you can get a new 2006 dodge for about 7000 more than what those used and abused cost. Plus the difference is financing makes the difference a lot less. Good luck

gravel rat, ive had several powerstrokes with way over hundred thousand miles, and never have issues with em, i know lots of people who have 100,00-300,00 miles on theirs (i worked at a ford dealer for over two years met lotsa people with high mileage powerstrokes) they maybe spend 200 a year in repairs! my 99 powerstroke, i bought with 95,000 miles, i sold it with 202,000 miles, i put a transmission in it and thats all! and that was my fault cuz i had a 120 horse chip in it....

I know that a diesel will last long, but with propper care, i've seen gas engines with 250,000 miles on them and stil kicking.

I've seen it too as well. Its rare and all the trucks I've seen like this were babied and never really hauled much weight or load except the bi-monthly trip to home depot. When it comes to a work truck, I won't buy a 3/4 ton or larger gas truck with over 120k unless it had recent trans or motor work or unless it is a steal and 1/2! I would not hesistate to buy a used diesel (anything but the GM 6.5) with 200, 300, or even 375K miles still on the original build. Diesels are awsome for longevity and Cummins leads the pack. The recomended overhaul period is the highest when compared to the others. The design is also pretty much unchanged. All dodge needs is a strong auto to handle the power, but since I can drive stick, I would just get a 5 or 6 speed with a cummins. JMO

The latested addition to our fleet, a 99, F250 Power Stroke pickup, just rolled over 250,000 miles today. We bought it with 242,000 on it in the spring. Have spent nothing on the truck for repairs so far. Do not see any problems of the horizon either.
