Re: what does "bullet proof" engine mean?
Sometimes people throw that word around when the work that has been done is far from "bulletproof" We've worked on few 6.0's that supposedly had this work, not the case at all. Unfortunately some people don't understand all of the terms so they get taken advantage of.
I would consider a "bulletproofed" 6.0 to at least have their EGR & oil cooler installed. There are many other things that need to be addressed with a 6.0 but we don;t need to get into that!
