Out of curiousity, how would I be able to tell that my injectors are leaking?

I need to know what too look out for on this truck.

thanks

the level of your crankcase oil for one thing....

balance rates, those can be read with a Tech 2 or Predator...

Also, desired versus actual fuel rail pressure. Should be pretty close at steady speed. If with a TechII, command to max pressure (was 150 Mpa on the early trucks) should get very close to 150.
