Looking to Buy a 6.7. Things to Look Out For?
Hey Guys. Been off the forum for a long time but I'm in the market for a 6.7, LB SRW 4x4. With my budget and looking at the market I'm thinking a truck I find will have ~ 75K miles on it. Anything in particular I should look out for with these motors/ gearboxes?
(This bit might need to be posted in the towing forum?):
For some reason I'm worried about buying a truck that has been used for excessive towing and might have been run hard without me knowing it. Is this a valid concern? Any signs that this might have happened? Any way to tell if the truck at one point had a 5th wheel hitch?
Thanks guys for any help.
Cheers,
Max

Definitely! I'd throw that in the "usual stuff" category I mentioned haha. I bought my 2011 used, from the original owner. He had a stack of receipts that backed up a very nice maintenance schedule. I was impressed actually.

Not a lot of issues with 6.7 trucks. Look for fluid leaks (turbo fittings and radiators leak from time to time), but if you're looking at trucks with 75k on them you might have some factory diesel warrenty left (5 years from in service). Powertrain is 60kmiles, but the 6r140 trans that's bolted to it has been exceptionally reliable, even on trucks that don't leave home without 10k pounds dragging behind. I'd wager it's the best transmission available in any diesel truck today. Early trans needed updated soleniods, but thats about it for issues there.
A truck that a had a fifth wheel hitch is pretty easy to see. If universal rails were used you'll see drilled holes in the bed floor. Factory fifth wheel prep is also available, in which case you'll see five pegs in the bed (center hole for gooseneck). If lots of miles were spent towing 5er or GN, the powdercoat will be worn off the tops.
After purchase I'd put a cold side intercooler tube on it. Then drive the wheels off it.
And remember, we want pics....

The trucks aren't toys, they are made for towing whether it is a goose neck, 5'r or tag along...you are being a bit OCD on the towing in my senile thoughts. Finding one with 75k or less, I wouldn't even be concerned if the previous owner(s) towed. The trans fluid is 150k miles when Ford says to change it.
