most of us know that a 7.3 powerstroke diesel, with the right maintenance, can last basically forever. my neighbor has proven this many times. he has a 2001 F350, purchased new, which now has about 180,000 hard, neglected, miles. a normal start up for this truck in cold weather, or any weather, he cranks it, pumps the gas till it starts (starter is weak, hes gone through 4 starters) and then he backs up on to the road and pins it to the floor. always has it pinned to the floor when taking off. one day he had his hood up, i said hey let me see how dirty your air filter is lol. had a rats nest in it plus about a 6 inch wide hole, and he had just come back from a 300 mile trip like that. id love to see how the compressor wheel looks like. the worst part is he told me he waits to change his oil until his oil light blinks, which is extremely bad for this engine to wait that long cause the injection system shears the oil. and he also runs a OCOD. who knows how much longer this engine will last lol. just thought id share with yall.
