Re: Diesel Power Discussion
We have 2 2006 6.0L Power Strokes at work with over 100000 miles on them and the only non maintenance repair so far has been high pressure standpipe "O" ring replacement. Both vehicles gradually started to crank longer then normal on a hot restart because of high pressure oil leaking by the "O" rings. The new "O" rings were an updated design with backer rings.
