2012 6.7 Diesel

Same here, just remember someone who feels angry about something is much more likely to complain online loudly. There was ONE fellow here years ago that claimed to have the fuel pump problem. That was the one and only and I never heard what the resolution was in that case.

dont listen to the gloom and doom, tsb's mean nothing they are a way to efficiently repair a condition if it comes up. there is no oasis on valves, fuel pumps , or glow plugs. there was oasis on egt sensors, the sync system and something else that are all covered under there own warenties. for what it is worth I have only heard about the fuel pump on the internet and I know no one who owns, or a mechanic that has ever seen one. not saying it isnt true but it isnt as prevelant as the internet has made out. I went from a 99 to a 14 and I stand by it was the best upgrade I have ever made in trucks, and I loved my 99.

I'm looking to buy a 2012 f350 super duty 6.7 TD CC LB 4X4. I'll be pulling a 12,500 lb. 5th wheel trailer. My question is how many miles is too many for this truck? I'm new to diesels and from what I've heard diesels last longer than gas engines, but with no personal experience, I need some help from you diesel experts. If you were buying this truck how many miles would cause you to shy away from the truck?

I have 178k on my 2012. Replaced auxiliary water pump and lower radiator hose. Still going strong hopefully for another year or so

Now that I'm at it, I didn't mention valve cracking problems.

I also was remiss in not mentioning the tons of turbo failures they had.

Interesting that Ford fixed ALL of these problems later on. The valve issue were listed up the 2015 in their TSB's. Pretty telling.

The glow plug clown is in error.

The cracked valve problem was poor heat treating and corrected on trucks produced after 3/28/2011.

The TSB you are referring to, I believe, was a noise problem addressed by a customer advisory on how to operate a diesel.

The ceramic turbo bearings did have a higher failure rate than later steel bearings.

Nope: Sorry but you are misinformed.

Tell that to thousands of people that had trucks bought after 3/28/2011.
Here is the TSB for the valve cracking problem with the 6.7 Powerstroke engine.

Do you see the years affected?

The AERA Technical Committee offers the following information on a rough running or engine misfire on 2011-2016 Ford 6.7L diesel engines.

According to Ford TSB 16-0041 Ford will replace 8 exhaust valve because of a rough running condition on the 6.7 Powerstroke made before 2/23/2016.

PICKUP - 6.7L DIESEL ENGINE - RUNS ROUGH DURING EXHAUST REGENERATION PROCESS - BUILT ON OR BEFORE 2/23/2016
[************]Publication Date: March 7, 2016

FORD: 2015-2016 F-250, F-350, F-450
This article supersedes TSB 15-0106 to update the Issue Statement, Service Procedure and Part List.
ISSUE:

Some 2015-2016 F-Super Duty 250-450 Pickup vehicles equipped with a 6.7L diesel engine and built on or before 2/23/2016 may exhibit a runs rough/misfire condition only during the exhaust regeneration process. This condition typically occurs on light throttle tip in between 64-113 Km/h (40-70 MPH) and will not set diagnostic trouble codes (DTCs). The concern may be intermittent and a knocking noise may be present during the concern. ACTION:

Do you see the dates? Some say the valves weren't make to spec and some say the guides were too tight. Some say it was a glow plug problem. The bottom line is these engines are blowing up for whatever reason. This is the reason they made big changes to the 6.7 after 2015. If the CP4x pump doesn't get you, the valve problem will. If not that the glow plug issue will.........

If anybody asks me about an early 6.7 I tell them to stay away. BTW I do that for an CP4x truck out of warranty......Ford, GM, or Ram. Those pumps are junk IMHO.

If anybody ask me about a 2016 on up truck, I would have a preference but I would take any one of the big 3 diesels. Not so with the older ones.

I know two people who have had the radiator problem. One traded his truck in (on another F250 6.7). One fixed it and is still running it (he still likes it better than the Dodge he had before).

To me it's not just the engine you need to be concerned about. Everything else in the truck wears out too. I guess it all depends on budget, but I am done buying or owning vehicles with more than around 120,000 miles.

I have ~180k miles on my 2012 6.7 Super Duty and the only problems I've had were the EGT sensors, Nox sensor and recently a AC condenser coil. As for the engine and transmission I would say that can go an easy 250k miles.

There's a couple of guys on this thread who like to promote internet amplification and perform the same routine every time so take their claims with a grain of salt. I also have ~20 percent idle hours (>1k hours) and no EGR or soot clogging issues.

I wouldn't hesitate to buy another older 6.7 Super Duty but like any used truck you have to give it your due diligence to give the truck a good look over. I'm quite content with my truck and still plan of keeping for the long haul.

BTW; GM also had the same 4.x fuel pump problems. I would not recommend buying one of those trucks out of warranty either. IOW's my recommendation would have been the same, but I would have put up less links for failures. :B

There is always a lot of misinformation. There were no glow plug problems, Ford used the destroyed glow plugs as a way to diagnose a complete engine failure. There were some bearing failures, particularly in the first ones built in 2010 because HoseB didn't tighten the rod bolts. Ford used the same fuel pump as GM. The fuel pump disaster kit is only partially effective. Parts kit to replace a catastrophic HPFP failure can be had for about $3,000. Radiators do have too many failures, Ford now eliminated the top left mounting bolt to relieve some stress.

A big expense for a high mileage truck can be a DPF that is plugged, some can be cleaned. Like previously mentioned, check idle hours. Some folks like to play big trucker and idle them needlessly.
