The first model year as usual is the problem child, 2011 prior to the end of March 2011 had some problems, 2012 was unaffected, enjoy your truck, and just keep it serviced. use the right oil, Aluminum cylinder heads always scare me, Duramax had a tough time keeping them sealed, so they lowered the compression ratio, and they are holding up much better. You have no worry's.

After a pause since March 8, as of today my active regeneration jackhammer valve issue is back.
I was merging into traffic and a regeneration started as I was merging building speed to around 45 mph and the engine valves started jack hammering at a level around 60% of the most severe case I have had.
This proves Ford full synthetic 5w-40w oil, Ford PM22A Cetane boost nor Archoil diesel catalyst to reduce soot will not fix the problem.
It is a factory defect with mine first showing up 3 months in at 4100 miles.
I would not doubt at all that the real truth is those engines that were held back and rebuilt due to issues February thru April last year were gradually dispersed out over the past year and i was one of the unlucky ones to get one of those engines. Many individuals don't give any concern, use no additives, use non Ford Oil, buy their diesel anywhere they please and do not drive their regenerations to completion and have no problems what so ever.
It is time for a full replacement truck from Ford.
1:38 video around 198mb in size in .mov format recorded on an iPhone the best I could in traffic.

This affects 2011 though 2013 model year 6.7L engines if I am not mistaken.

This is not the same issue being discussed in this topic. What you are describing is an engine that exhibits a runs rough/misfire condition only during the exhaust regeneration process that usually produces a knocking sound. There is a service bulletin (TSB 13-9-15) that addresses this by diagnosing/verifying the concern and replacing all of the exhaust valves and seals on the left cylinder head.
In talking with some people who had their 2011 to 2013 engines torn down, the problem came back after a few thousand miles
Also, the most recent individuals (6) who have had this issue show up in new 2015s in the first few thousand miles of use have not been told to tear the engine down and rebuild the valves. Instead they have been told the issue is under 'engineering investigation' and to monitor oasis for further updates.

This means exactly what you might be thinking. Ford does not know exactly what causes it OR they do and they are not sure how to correct it. YET. I have full confidence that the Ford engineering team will figure it out and issue a repair. This is the common progression for this type of situation.

Personally, I don't think it's worth being on pins and needles over since you have 75,000 miles on a four year old-ish truck it's probably safe to say your truck is fine. ENJOY YOUR TRIP! 
Don't get me wrong on this - I fully understand the potential for a failure to present inconveniences, unexpected repair costs and such but statistically the number of failures is very small in the grand scheme of things. This is one of the negatives with respect to the Internet and public forums. We read about problems and horror stories and get worked up into a tizzy over something that will most likely never happen, failing to realize how small of a percentage of vehicles are actually affected. Remember, you are more likely to read about someone else's misfortune more than all of the happy truck owners but if you peruse the forums long enough there are many feel good posts as well. Think about it, do you ever hear someone COMPLAINING about how awesome their truck is? Again, ENJOY YOUR TRIP.

Mine is a May '10 build truck. The only noise issues I have is occasionally it will sound like and old Cummins and it'll do that for a few minutes and then go to quiet mode. This only seems to happen after it has been just started and for a few minutes after the start. Of course there's the standard typewriter noise all the time.

My F 350 was built in June 2010 and is just days short of 5 years old. The truck runs and looks like it is brand new. With the exception of driver's side electronic mirror that failed a couple of months ago, I've had no problems. And as one poster indicated earlier in this thread, this is perhaps the best vehicle that I've ever owned.
As Ford Doctor has suggested, there's probably quite a few like us out there that have had few if any problems but you don't hear from them very often. Yes, we aware of the potential for a valve issue, but there is not convincing evidence that catastrophic engine failure due to the valves is an inevitable fate for our trucks given only a small number of trucks that have actually had this failure. And many of us have insured ourselves against this small possibility with Ford ESP or other plans. The cost of that mirror was $1200, but I only had to shell out $100 to get it fixed under this plan.
