I have the LEAST reliable tow vehicle in a 6.4l Powerstroke. I've found in ANY diesel application you MUST use a lubricity additive at very minimum as the current diesel fuels are excessively dry thus causing the fuel system failures you're seeing in this thread. I use both Arch-Oil and Opti-Lube at every 3/4 tank fill up, never run below 1/2 tank and steer clear of bio-diesels per my owners manual. The ford-trucks forum I use also says to change the Ford or Racor brand only fuel filters every 10k miles or 2 years as well as drain the condensation bowel monthly.
I hear the new GM 6.6L gasser is a good engine, I know their 6.2 rocks in the half tons. I haven't driven one yet though, If I bought a new truck, I'd heavily consider the 6.6 gas. However, a new gasser still costs twice as much as my used duramax haha and I just cant justify that kind of payment to drive it 5k miles a year.

Now a week later the VG turbo is acting up and vanes are sticking periodically making it act like an ole 12 valve.......ugh! He didn't take the turbo off to do the work either so not his fault. I wonder if it didn't like the 2-stroke oil I put in tank as fuel lubricant or put too much in and gummed the vanes up. Lack of use also more than likely culprit. Haven't really dug into that one yet.

Trixie is back in action, and for a week ran stronger than it ever has since I've owned it. Pretty sure I had couple dirty/leaky injectors as it would always smoke a bit for first 10-20 seconds at startup and never got that stellar of MPG. Was getting consistent 2 mpg better after I picked her up and much better throttle response with more seat of pants power than before. Poor kid mechanic thrashed on her for a solid week to get it done before the holiday weekend. It was a heck of a job by the time he rigged the Air Dog system and everything. He called me up evening I was supposed to pick it up saying it was knocking and pinging, and high fuel pressure codes. I did some googling and luckily found that the FPR and CP4 wire harnesses are identical plugs and length and will cause that when switched. He switched them around and ran like a Swiss watch.

Can’t give any suggestions on the turbo. Oily exhaust tip will suggest too much 2stroke but I doubt that caused it?

I totally agree with you on how expensive these new trucks are to work on after my 6.7 needed turbo and head work after a glow plug fell out I decided to go back to my roots and built a truck from the ground up to tow my 38 gun one that I picked the newest platform that was pre egr and dpf. Ended up with 2005 dodge 3500
