High Mileage Reliability?

Hey guys,

I'm tossing around the idea of picking up a 150k-200k mile 6.7 as a new tow truck. It looks like they're going for low $20k's which makes them really tempting, since the dodges seem to be $5-10k more and the 68rfe can be pricey to fix or improve on compared to the 6r140.

I was thinking of a 2012 and just doing deletes and slight tune (be around 450-500hp). Stock turbo, longblock, transmission, suspension, and fueling. Replace the turbo with the newer style if it fails.

At 200k-300k what things typically go besides normal stuff like u-joints, seals, tie rods, etc...

Thanks
 
With the exception of the turbo issue already noted, these trucks seem to just keep on going. The only two super common issues are the turbos on the 11-14's and the plastic intercooler pipe we make the fix for. Other than that, I'm not seeing any major patterns with the high mileage 6.7's.

That's what I like to hear.
I've heard about many people replacing the plastic intercooler pipe.

I've been looking for a decent 4th gen and then I noticed how cheap these are going for and it blew my mind! I think this might be my first Ford truck.

Any variances between deleted trucks and not?

It's all going to depend on the guy behind the wheel.

I can tell you right now that running exhaust through your intake is not a great way to make a truck reliable. Most of the "free flowing" trucks tend to go a long time without any issues. It's the ones that have had crap running through them their whole life that seem to be the most problematic.

Any idea on how many miles they seem to run with all of that before having multiple issues related to it?
And what happens? Glazed cylinder walls, carbon buildup, injector nozzles?
 
Friend is the sales manager at a local dealer. They have replaced a few engines under warranty but only in the F550's and they were all because of dropped valves. The only other one they have done was an F350 that the owner never changed the oil. Looked like glue when they drained it. In 115k miles I've had one o ring failure on turbo coolant line. Friend has same truck and that has been the only repair in 130k. Both are "free flowing."

On the engines that were replaced under warranty both were no questions asked. They called ford and complete new engines showed up in a few days.

Of course, but odds of finding a 150-200 thousand mile truck thats been deleted at day one and not abused is pretty slim. Reality is that the available inventory is going to be stock trucks driven by a 40 year old to work and to camp.

That's why I asked.:rockwoot:
 
I've only got 64k on mine, been deleted since 46k. I can say that the issues I had with the truck happened prior to deleting and I've only had a small issue recently with the tuner. Truck has been flawless. I wouldn't hesitate to buy an older truck, delete and enjoy.
 
I am in the hunt for something along the lines of the OP also. There are a lot of Hauler trucks out there that have been used to pull campers and such. A Carfax gives you some insight what kind of issues it has had and who to call about the vehicle. Most dealers and repair shops will tell you about what was done when it was in. I have seen a few with almost no warranty claims in the 1st 100k and to me that says a lot about the quality.
 
Doesn't really help much on what fails or doesn't. But I saw a late ford with over 800k on original engine an trans. Seemed far fetched when I first seen it, but there it was.

Carfax has Phuked more people than Jenna Jameson. Those reports only show what dealers or insurance companies claim. After a hurricane there are no shortage of flooded vehicles that get dried out and traded off. Wrecks that get fixed for cash just to keep it off the record. I wouldn't put much trust into those reports.
 
I've noticed quite a few 6.7's locally that are smoking like a SOB. Idle haze and a thick haze while driving. You can tell by listening to them as you pass that something isn't right. Is this usually a bad injector? 99% of the time it's the guys hauling wedge trailers with cars on them.

Hopefully that's the case and not rockers again...

If it's injectors, I'm guessing a better fuel filter would fix 99% of the issues.

I broke it to my wife that we're not getting rid of the 12V when I finally grab a ~2012 6.7. She took it pretty well. She said "Good, then you don't have any reason for this to turn into a project vehicle!" ha ha
She knows it'll get deleted and under-body sprayed at a minimum.
 
I have officially joined the 6.7 club. 2011 F350 CCLB Lariat already has been on a diet. This time next week I will be on my way home with it from down south.

Thanks Eric, I am excited to have a pickup again. Might be time to put the Excursion up for sale again.
