    I'm sure this topic has been hashed over a couple hundred times, but I'm new here.

    I am curious to know what the best diesel is according to you.

    For ease of argument, lets concentrate on pre-2003 made engines.

    I suppose the criteria would include longevity, ease of obtaining parts, manufacturer support, power/torque, and several other things I can't think of..

    Cummins -- Big Cam 350
    Meets and or exceeds all your criteria

    If we include all diesels, how about the Int. 7.3 turbo as found in 2000-2003 Fords?

    5.9L cummins, 89-07 Dodge ram. Alot of external changes, but the engine itself... almost 2 decades of consistant strength and reliability.

    I second the 5.9 cummins I have a 2005 dodge with 450,000 miles and still on original injectors. I also have a tractor with the 5.9 it has 13,000 hours and never opened it up either. The 7.3 is a good motor but they have no torque on the lower end where the cummins has good torque through the range.

    In short, there is NO Consensus!

    I agree with Qball about the 71 and 53 series Detroits, for the reasons given, and I have had great luck with the L10 Cummins.

    3406 Cat Mechanical Version. The 3306 is a good one also, as they last a long time in a piece of equipment

    I'd say that any 2 stroke detroit would be cheap and easy to repair. The equipment that I used to work on was Cummins Compressed Natural Gas and was a headache to work on and keep running. It seems to me that the simpler it is the easier it is to keep running. The Cummins CNG is not user friendly and cheap to keep on the road. Lots of check engine lites.

    I'm a two stroke Detroit guy myself, but Mack, Cat, and Cummins have all built excellent engines also.

    I don't want to ruffle feathers....but..

    I HATE 2-stroke Detroits. Gutless loud pigs. Sure, they run forever and a few days besides, but how I hate them..


    I vote for any air-cooled Duetz.

    Any opinion on a late 80s 6068 Deere?

    Perkins 3.152 and variants - over 50 years production. Speaks for itself. They probably have it on the numbers as well.

    I am lucky to play with just about every size and style engine in common use, the Perkins engines (CAT) are very well built and must be the cheapest engines about to rebuild, the 3 cylinder 152 unit can have new piston/liners (sleaves) bearings and gaskets for about £230, some people call them "Ships Anchors" but not on this side of the Pond, in numbers alone they would be way ahead possibly double ahead of any other engine, the CAT 333c and 3306 unit is a very simple unit, they like to come to bits every few years, again this engine is cheap to repair with Non OE parts that are of good quality and you dont need any fancy tools to tackle them generaly, Cummins L10/M11 and Big Cam 14 litre engines are built using a now common style fuel type system "common rail" the Cummins pressure time (PT) fuel system is a great design item the Jacob's Brake is something that should be fitted by Law to every Diesel built, but the engine is fairly technical in its construction, its the small details that make them run well, this realy takes them outside the average Saterday afternoon spanner man scope, I hear on this Forum lots of 5/6 inch pound talk????, the Detroit thing I dont understand as all the 53 and 71 series engines I have worked on are fairly complex, the last unit I touched was a V16-71 this is 2 V8's poked together, 4 valve head plus all those turbo's and blowers and a cam shaft running at crank speed, then liners with about ten different fit spec's, the average fitter would be well out of his patch, a very famous engine from the past in the U.K. was the Gardner 180 and 240 this was a real Gaffer's engine good on fuel and ran for ever, it had shrouds on the inlet valves, the injector pump was a thing to admire, but they came from a time now gone into the past, Duetz engines the air cooled sort are great and stong runners, the blower fan only has to shift 1/3rd of the wind of a water cooled engine to keep its self running in the green, they are well built and well liked by anyone that has run them, but the little 3 pot Perkins has to be king of all it does, its only a small engine but has great Heart.
