I have a 2002 7.3 Excursion with 209k and planning a 5k mile trip in june. I have been prepping the vehicle for the trip with new HD alternator ,6.0 cooler and soon to be installed air bags. My question is with how many miles I have should I be worried about the injector orings going out,and also the oil cooler seals needing to be replaced . I'm just not sure how long I should expect these things to last, so I'm looking for some advice on how long these should last.
