I was wondering what you truck guys' favorite diesels are. Personally I love the 5.9 cummins, I Know a guy that has 300,000 on one and it is still running strong, I think they are the best built and they always get the job done
Cummins has historically been a workhorse, with a few exceptions. I'll agree that the new Fords look interesting. I saw a lot of the preliminary design specs and I can tell you they may have a winner. This time it looks as if they paid attention. If I were in the market for a diesel, I'd wait until the new Fords shake loose.
I drive the new cummins 6.7. 69000 miles good so far, emission standards suck. particulate filter had to be replaced, under warranty thank god, a 6k dollar job. Diesel shops can gut the exhaust and throw in a computer to override emission standards, ill have to do this at 100000 miles. My brother has the pre emissions duramax chevy. Good mileage and lots of power.
I wish the Mercedes diesel was available in small trucks. Damn things can easily top 300,000 miles, and often get over 400,000. Brazil is making a copy of the old FJ40 Land Cruiser, with a Mercedes diesel in it. Smart move on their part. Wish it was importable.
Do not know about the best....but I can tell you STAY AWAY FROM THE 6.7 CUMMINS! By far, without question, THE worst running most pathetic engine I have ever operated in my life! Absolutely miserable motor! Jerry
I have a Cummins 5.9 a Cummins 3.9, and a MBZ OM 617 which is the 5 cyl diesel in the 300SD mine is 83. All of these engines are really good engines.
Of all internal combustion engines arguably the longest living engine is either the Onan 2 cyl used on generators, both the 18 and 22hp version, or the MBZ OM 616 diesel which is the 2.4L NA 4Cyl engine from the 240D. The OM617 is next as it is just a Turboed, 5 cyl version of the OM 616.These are well documented long service life engines. It is not at all unusual for an Onan engine to go 20,000 without overhaul. That's the equivalent of 1 Million miles. I have personally seen 3 240D's with in excess of 750K on them with the original engines.
There are more OM616 engines over 1 million miles than any other automotive engine with the 617 close behind. If you saw the inside of a 616/7 engine you'd understand why. They have nitrided cranks and cams, valve rotators, and a lubrication system second to none. plus that they are not being worked very hard in their stock state of tune. I have seen 617 motors in MBZ race cars, Galandenwagons, MBZ mid sized trucks and Haglund Snow Machines. I have also seen them swapped into Jeep Wranglers, and a variety of other cars and light trucks on my other favorite website www.4btswaps.com in the MBZ section.
The newer versions of the MBZ diesel motor are catching up in the longevity race also. The motors that followed the 616/7 series which ended in 1986 were the OM 603, 602, and 601 series which were 3.0L -6cyl, 602-2.5L 5cyl and 601 2.0L, 4 cyl. engines. these were completely different from the earlier series, and used aluminum Heads and a semicomputerized Bosch Injection system. The current OM 606 2.5L 5 cyl in the Dodge Sprinter vans is a revised version of the 602 motor with a Common Rail Injection system.
Next, we are getting into "Just My Humble Opinion", the Early Cummins "B" series engines. The 6BTA-5.9 being the engine in Dodge trucks from 89-96. This is a mechanically injected 359 CI turbo diesel. This engine in automotive aplications had between 160hp and 180HP. In marine applications it can go up to 375 HP, and Gale Banks had one in a truck that he squeezed 450HP out of. Marine versions above 300 hp don't last very long due to the continuous sustained load of a marine application.
I also have a 4BT-3.9 239 CI 4 cyl engine in my Jeep Scrambler. IT came from a Doritos Van! It has 105 hp/275flb of torque, and runs a GM TH400 trans with a US gear overdrive and an Atlas Transfercase. This engine is exactly like the 6 cylinder version with 2 cyls missing. Uses the same pistons, rods and many other periferal parts.
I used this engine because I have personally seen a dozen or more 4BT's with in excess of 400K in 10,000lb delivery trucks, and I have seen 2 in generator sets that had well in excess of 20K hours on them, in fact they are both running right now! This engine in a Jeep application will last forever. It is easy to work on and will yeild between 25-30 MPG in this vehicle.
The original Ford light truck diesels were Internationals, and were good engines. Fords first attemp at it's own V8 in 2004 came up short, my neighbors's swallowed a valve with 26K on it. Has ran fine and been worked hard ever since the rebuild.
The Duramax GM diesels were originally Isuzus, but I think their new one is all GM. I never could understand why the company that owned Detroit Diesel would want to go to Japan for a light truck engine, but now Roger Penske owns Detroit so maybe they were too expensive. still?
Caterpillar doesn't make a light truck diesel. The 3126 is a great motor and is available in Motor homes F650's and GM 1.5ton and above sized GM trucks but not in Pickups. 300HP and tweakable just by the chip. At well over 1200 lbs it is just to big for a pickup.
If you would like to see my on going Jeep build you can go to www.4btswaps.com and search my thread in the buildups section. "here's the DeScrambler" is the name of the thread. It's got alot of pictures of the "from scratch build". I've got 8 years in this one, so far.
There is also a wealth of diesel information on many different engines and from many people around the world on this website.
This whole thread has nothing to do with Trap Shooting except, that my new Jeep will be my "Shooting Brake" and will carry me and my shit to various venues for sport shooting and hunting trips. Maybe I'll see you there?
But Really,,, this right here is why I am sold on the Cummins engines! 9 lbs!
I would have to agree, but not because of anything good. I made a ton of money over the years converting the GM 350 Diesel vehicles to gasoline power. That's what happens when you "retrofit" a gasoline engine to run on diesel. They just didn't work well and most owners either dumped the vehicles or had them converted. I still have most of the tools for those diesels somewhere. It was second only to the V-8-6-4 in stupidity. Marketing should never drive the development with untested ideas. Sounded good on paper, but didn't stand up in real life.
The real test of the longevity of a diesel engine is in the marine environment. You almost never see Ford or GM diesel used in boats.
You'l see Cat 3208, Cummins, Ford Lehman, Perkins and the latest John Deere-Lugger which in my opinion is the best for long range cruising. This engine proved itself by going around the world under power on a 40' Nordhaven.
On a boat its the equivalent of driving a truck uphill in 2nd geard all day long. The basic marinized good diesel engine should last 30k hrs. Gasoline engines in a boat are shot after 3k hrs,
They all have their advantages and disadvantages, it really depends on what you want. I'm personally a fan of the 96-97 Powerstrokes. I like the body style and the ease of the OBDII port. really any of the 94.5-03 strokes were great, not a big fan of the 6.0 but some people have had some luck with them. I drive a 96 F-350 4x4 dually, 5-speed, 4.10:1 rearend, with just a cold air intake and a 4" exhaust and average 21mpg mixed driving, with a tuner I can get over 24mpg. It seems that the older V8 diesels get a tad bit better mileage. If you are wanting to just look around and get more info check out the link above.
