My opinion these aren't the best kind of trucks to be bought sight unseen. Only under couple of circumstances I would buy a 6.4 sight unseen, one is if its brand new, and since in your case it isn't and it has 140k on the clock I would be sure this truck has all servicing documentation with it, and if it doesn't LOOK THE OTHER WAY. Because at 140k the coolant is supposed to have been flushed twice, and everything else(trans/transfer case/diffs) was supposed to be changed bare minimum at least once depending on oils/fluids your running. Like you I bought my 6.4 without really researching, I mean I researched generally before my purchase because I too bought mines used with 20k miles on it, but if I knew what I know now about this engine I would've at least tested the coolant for proper nitrate levels and if it fell below 300 ppm, I wouldn't even waste my time. Like your probably finding out now is that these trucks are very high maintenance and if the truck is neglected don't be surprised when your stuck on the side of the road. Take care of your truck and it'll take care of you.
All I got to say is Goodluck, and congrats on getting yourself a REAL truck lol
I too came back from the DARK SIDE a few years back, I sold my Duramax and picked me up this beast. Couldn't be happier(:
Just do a little more research about tuners and maintenance and all the answers will either be in this forum or others like THE DIESEL STOP, etc.
Thanks for the insight. I would rather NOT buy it sight unseen, but I'd prefer to get a truck from TX or that part of the US due to lack of rust. Plus I like the road trip. If it looks sketchy when i get there, I will walk away.

I asked a ton of questions because the truck had 196k on it. Sounds like a lot, but for a maintained diesel...not really. I was able to get home and arranged to look at it and drive it and I did. The truck ran great, drove well and looked just as good. Mind you it did have blems, but nothing that would be a deal breaker. I ran an Oasis report AND a Carfax after I looked at it and everything fell in line. The point of all this is to say that it doesn't matter if it has 10 miles or 500k, it's still a mechanical piece of equipment and sometimes they just fail. Granted some fail due to neglect, but some just fail. I can't say I would have bought this truck sight unseen though. I'm happy with it, it runs like a scolded dog and drinks more fuel than BP and Exxon can deliver! Don't second guess your decision, otherwise you'll constantly be worried about when "it will die". I've got my garage all stocked with exhaust, a tuner, new thermostats, oil and fuel filters and will do a system flush when I install the EGR delete. Do that, and you should be set for about 475-500 HP! ....and slightly better fuel mileage to boot!
I've seen the carfax but since its not a Ford dealer (mom and pops car lot), I wonder if they can do the Oasis report. Can a buyer just pay for it online somewhere or how does it work/what exactly does it show?
Sounds like you'll want to do an oil and fuel filter change on the spot, at least I would. Especially after doing my fuel filter last week and it appearing to be original at 56K and as black as my oil filter was. I instantly noticed a difference and towing the same trailer I've towed 3 previous trips(same place), I noticed a 2mpg improvement, no lie.
You cannot just straight pipe these, you must have a tuner to turn off the DPF and delete it fully, same with EGR. A tuner can just turn the EGR off without block offs or anything, but over time it's advised to truly delete them. Most just don't due to warranty and just turn the EGR off. Granted you're way out of warranty.
Look under the hood for any white coolant around the degas cap, and see if it has had any issues with that. On startup it should be burning clean, not much smoke if any, unless it's tuned/deleted, or something is wrong.
Hope it works out well, for the oil/fuel change you can just bring a few tools, or buy them and do everything in a parking lot. I would get on dieselfiltersonlines.com and buy the Racor filters now, then go to Wally world in TX and get Shell Rotella T6 and make the change to synthetic and do the full change there. Oh get a drain pan too so you're not just dumping oil. Also a new drain plug would probably be good.
I can change the fuel filter under the hood, and i'm going to look on this site to get more info on the one on the frame rail. I have no problem even changing the oil in a parking lot somewhere. Anything to get better mpg's and prevent problems on the drive back to Ohio.
If its been deleted, all that extra crap is not on the exhaust line, but how do you tell if its been tuned or not? is there an easy way (screw holes where the box was mounted, certain wires somewhere)?
Baldwin Filters are all i ran in my old 7.3L and my Cummins, are you all not a fan of them with the 6.4L's?
Thanks for the advice and comments.
