    My buddy's thinking of getting rid of his 4th gen (LT1 auto Z28) and getting a 2001+ pickemup with a duramax. If maintenance is regularly taken care of, how many miles can one reasonably expect out of one? I'm guessing around 400k.

    I've heard you want to get the newer Duramax over the older one. The LLY I think....

    I forget what year is the better version. But I've seen Powerstroke 7.3L
    go 500,000 miles properly maintained. :) Samething with Cummins ....I
    think one of those 2 made it to the 1,000,000 mark, but obviously the
    Dodge truck would have fallen apart Loooooooong before then.

    i'm a heavy duty diesel mechanic and have even seen older mechanically injected diesel non turbo engines run up to 750k before they even need an inframe overhaul . if you're really good with maintenance like changing the oil every 7500 miles and changing the fuel filter every other oil change you should be just fine . another really good item on any diesel engine is a water/fuel separator just after the tank and before the pump .something that i like putting in the fuel itself is fuel conditioner like what's available from lucas in the 5 gal bottle . this helps the fuel from becoming stale and wet with water . diesel fuel if left at 1/2 tank in cold weather will develop an algae type substance that'll clog up the fuel system fast also at a 1/2 tank the fuel will become very wet with moisture

    other things that help diesels live very long is being aware of EGT's "exhaust gas temps" and to not let those temps get close or over 1300 degrees as it'll destroy the motor

    so i would say you should be fine with the duramax for at least 750k before any mechanical issues arise

    All I'm gonna say, if you want a diesel, then get a Mitsi FUSO!!

    Imho, it's as tho ALL US vehicle manufacturers have done everything they can to discredit the diesel engines longevity that they try to SELL to us MASSES from the git-go when GM brought out the Olds 260 and 350 engines way back then!!

    And did anybody catch Ford's recent 750,000 to one million + diesel engine powered vehicles RECALL????

    And over in EUROPE, they have at least 50 percent diesel engine powered vehicles so go the f-- figure here!!!!!!!!!!!!!!

    they had a problem with the injector seals drying out causing fuel leaks on the injector rail .one thing that'll kill a diesel engines fuel pump and injectors very quickly is gas contamination .just putting in 5-10 gallons of gas in a diesel will within 5-10k kill the fuel pumps teflons seals

    yep some of the older generation 7.3 powerstroke engines had piston pin oiling issues and other oiling issues that caused alot of blown motors .the newer 7 litre twin turbo powerstokes were recalled due to fire in the tail pipes from raw fuel igniting

    The 01-04 Duramax has a 10year / 200,000 miles special policy on injectors if they are leaking fuel into the crankcase. GM pays for this. If this is what was going on, he's due a refund,
