Sorry to be asking so many questions. I am shopping for a 6.7 dually and came across a king ranch F450 that had one owner and exceptional maintenance. It is, however a earlier build 2011, 8/13/10. should I skip this one? I have read of dropping glow plugs and valves on the earlier ones. And some problems with the HVAC? It does have 126,000 miles on it, if it lasted that long could it be one of the good ones? I am looking at $35,000 and under and can not find ANY privet party Duallys in my area. I know the day after I buy one off a lot There will be one for sale just like it for $5,000 less privet party.
Thanks again, and I am trying to do a search on all my questions, and have learned a lot already, but it not easy to find ALL the answers.

 

I owned a 08/10 build 6.7. traded in at 130 k still running strong.. I've seen guys here posting heavy use commerical 6.7's of early years over 200,000 on them no issues.
Maintain it..use a fuel additive Ford makes... and you should be good.. I had turbo replaced at 105k... which they have changed design since then..and AC evap at 70k... that's it.

 

I would pass on all 2011s, why take the risk. What is your plan if you hit the lottery and have to write a big check to get the beast back on the road. Plenty of 2012s and later available.

Not sure of any glow plug issue but I don't read every thread here.

I have found 8 2011 that meet my needs. The one has good maintenance records. I have only found 3 2012, one is too beat up, the other to are about $10,000 more that the 2011s.
Then there is the question what would be more reliable, a well maintained 2011 or a abused 2012? I will need a truck with en the next two weeks so I can't be too picky

 

I don't think good maintenance or poor maintenance has anything to do with the 2011 valve issue. It's possible that the 2011s are cheaper and more available because some buyers, like yourself, are educated on the possible problem. Accepting additional risk means you get a lower price. This issue is one thing that makes the 2012 and beyond more valuable to the educated buyer.

You are fortunate that you're an educated potential 2011 owner. Plenty of threads here of unsuspecting buyers having the catastrophic experience shortly after taking ownership and Ford offering no help.

Thanks again for the responses! I am going to look at a 2012 tomorrow at a dealer and see if I can get the price down . King Ranch f450 with most of the options I want, but the carfax showes it is out of Alberta so I will need to look at idle hours. Anyone know if they salt the roads up there?

 

Wasted time at the dealer. I drive two hours and the 2012 f450 king ranch morphed into a 2011 lariat with rust issues. I told the salesman I came to look at the 2012 KR, his response was "close enough". I left NOT happy
The choices I have is another 6.0, but after looking at the newer trucks the 05-07 just don't look that nice any more, my wife even feels the same way. I can go with a 6.4, lots of them in my budget, but heard some really bad things about them. Or, buy the 2011 and gamble. I thing my odds are better with the well maintained 2011 than a 6.4. So I will go look at it tomorrow.

 

I have a 2011 and overall have been pleased with it. But, mine is a Job 2 truck, which includes chassis and engine upgrades.

Because of the issues with the early Job 1 trucks I would never consider a used one.

There have been a few 2012 models with turbo issues, but I don't know what is different with the turbos from 2011-2013.

 

It seems like I saw the TSB doc for the valve issue, and in it, it listed the build dates for the affected engines. If you can find that, and buy a late 2011 build, you should be ok.

 

I think Job 2 started sometime in August 2010

 

I found a link to the TSB here: http://www.powerstroke.org/forum/general-6-7-discussion/420657-engines-breaking-valves-information-ford.html#/topics/420657?_k=jic0l5

The above TSB references glow plug damage, which was how they looked for confirmation of the problem. the issue with this was that there were some defective exhaust valves that came apart, and destroyed the engine.

 

I believe that tsb is for the bad glow plugs that the tips would fall off and kill the engine. Right or wrong I now own a 2011 F450 with 125 000 miles. I figured if it made 125,000 it probably one of the good ones , or, it has been repaired. I hope to find out more soon.

 

Congrats Bob. I'm sure you did your homework.

 

I think you should investigate ways to insure the engine against catastrophic failure. Ask your agent "I want coverage that will replace my engine if it blows" and see what happens.

My 2011 that blew up was built 07/10. I hope yours is a good one.
