im not say that you in particular think that that is regular maintenance stuff, but that is stuff i here all the time as to why diesel are ridiculously expensive. which is usually never the case unless you buy a truck that has been pounded to shit or is one that just had problems right off the factory line. there again you can get the same thing with a gas engine, i dont think that ford planed on having all of the cylinder head problems that they are dealing with in the 5.4’s, but sometimes shit just happens.
yeah if my 95 wasnt 2wd i wouldnt have gotten rid of it. it wasnt ever babied, but it always got maintnence when it needed it. im sick of hearing that they were all pieces of shit and blew up, when all the ones that ive seen blown up were going 25k+ miles between oil changes and didnt know what maintnence was. i know they werent the best, but they didnt ALL blow up.
i had the boost cranked up on mine and had the fuel going right to it and that truck never skiped a beat. it would walk by a cummins 12valve any day of the week.
but oil changes and proper cool downs are crucial for turbo life, if your using your truck like a truck you need to let it cool down before you shut it off. the turbo bearings reach some pretty high temps, and if you just cut off oil flow the the charger while everyting is still toasty, the oil will actually bake to the turbo shaft, causing pre-mature wear.
and a big thing for fuel systems, especially for older trucks that are now running on this new fuel, is runing something for a fuel additive. the new fuel is as dry as it comes, so a little addded lubricity is a necessity.
