Looking At a 2011 6.7 should I be worried?

Hey all,
I have been wanting a ford diesel for some time now. My local dealership just got in a 2011 F350 lariat. I test drove it yesterday and it seems to run very nice. The salesman told me that when it came in it had a bad turbo, so they put a new one on it. He pulled the oasis report and all seemed to be general maintenance items. There was oil changes, a leak, and a ball joint. Nothing to major. I do not have the actual born date of the truck yet so I don't know if it is an early model 2011 or later model. The truck has 81150 miles on it. I hear some say don't touch the 2011's and others say they have 300,000 miles on one.
What do y'all think? Thanks for any help.

well generally, the 1st year of any diesel motor/trans will be a learning curve for the manufacturer and then for the owners.

@Spaknives - Geez, the engine is just broken in

To check:
- does it have new exhaust components? If so, walk away. PO did the DEF delete, with a chip mod and that probably blew the turbo. Also means the engine may be also on the way out. These trucks come with lifetime SS exhausts.
- check the shocks, springs, and transmission play. Drive and park the truck on an incline. Did it roll a whole bunch? Shifting ok?
- if it's 4WD, check when the front locking hubs were serviced.
- are they willing to give it at least a years warranty?
- when were the brakes last serviced?

As stated above the early models had growing pains, most say stay away from pre April 2011 builds so look at the door tag it will state the build date if your not near the dealership call and ask them to let you know the date on the door tag, blown turbos on the 11-14 trucks were common they were a weak turbo with bad bearings from the factory but had zero turbo lag the 15+ turbos are a direct replacement and not a sequential turbo so they can handle much higher boost pressures than the 11-14s could. Just do your normal checks on the vehicle and the build date is just a guide any vehicle built any day can have issues minor or major especially when buying used, but knowing itís a early or late build helps some in there decision as the early models did have valve issues.

As stated, the early 11s had some problems. If it's after the date of the valve issues and you can get it for a decent price I wouldn't be afraid of it. I drive the snot out of mine and it hasn't given me any problems. Just oil and fuel filter changes. Had the water pump go on me, but that was within 2 weeks of owning it and the dealer replaced it free and clear.

Thanks everyone for the input.
The dealership did just get back to me and said it was built in December of 2010. That is a little earlier than I had hoped. When I drove it everything I looked at seemed to be stuck, but I will have to check and make sure.
When you say they had valve issue is that the glow plug issue I have read about where the glow plug may break off in the cylinder. Or is there other valve issues?
So is December 2010 to early? I was kinda getting my Hope's up for this, but now I am pretty nervous about buying a lemon.

Find a later build date like 2013ish and newer. The 2011's gave ford a very bad name with the failure rates:

poor material used in bearings for turbo, glow plugs braking and eating a cylinder, sensors and dpf/eef system failures, lifter/valve mechanical failures eating the engine, coolant system leaks esp with radiators, The newer series of 6.7L are making big waves in reliability. but, the 2011's were not a good year plain and simple. Late 2012's and up had some changes and it seemed by 2013/2014 they had it all figured out.

-99 F250, 4X4, 6.0 trans cooler, 08 mirrors, 05 grill, AIS Intake, lvl kit, JW Vbody, cncfab hpop lines, WW2.

04 Excursion Modified, 04 F350 Modified, 06 F350 Modified

Interested in learning something new?

Well I don't like the sound of that, seeing as I how I bought a 2011 with 165k on it! LOL
Honestly, I had the same worries as you. If you can get it well below Blue Book, buy GAP insurance, and everything feels tight, then go for it. That being said, these trucks are nice but not really "rare" so there is no harm in just being patient and waiting for a low mile 2012-14 to come up.

It really just depends on your budget. But I agree, if it looks to have been modded and then put back to "stock" to sell, I would run in the other direction screaming.....

Cheers!

Let me help with the details-
-turbo bearing failures largely attributed to early tuning, and being horrifically overspend. Yes, they fail in stock form but seldom.
-glow plugs never were an issue. The problem was a limited number of trucks in a specific vin range that had subpar heat treating on the valves which led to them cracking and destroying the motor. First step of troubleshooting was to pull the glow if and see if the tip was gone "ding ding" guess what, the bits of valve took the tip off.
-emission related sensors causing the truck to shut down was corrected by an updated flash that simply put the truck in limp mode instead of disabling the engine.
-the lifters are the same now as they were then. Higher miles and engine hours show the failures first, hence why the oldest trucks may start having problems.
-same story with the rads, higher miles equals more failures. 11-16 rads are a the same. Check body mounts for excessive movement before replacing the rad.

Don't broad brush 2011 as a bad year. Not the case at all.

Don't mind him, he's just super negative towards the '11s. Any truck can have a failure regardless of the year.
