Engines breaking valves- information from ford

I did some digging (a lot) and found a post mentioning TSB 12-11-11 pertaining to our trucks. I went and paid for a month of access to the ford TSBs after being unable to access this TSB from any other source I could find.

This TSB does not directly state "trucks built before this date may have bad valves", but it's the closest thing I've been able to come across to a probable cut-off date for this issue.

I was unable to copy and paste the contents of the TSB, so I had to retype it. I tried very hard to type an exact copy, but it may have some minor typos. Some of the formatting got lost, especially at the end. I hope some of you find this helpful. Here is the TSB:

Good info, thanks for sharing. I wish Ford would share their corrective actions that began on 3/30/2011 (or all improvements implemented to improve performance/durability). New materials for valves? Dimensional changes?

That would involve admitting that they did something wrong. Not going to happen. I'm really disgusted with them as a company due to how they handle warranty issues and known defects causing problems after warranty.

Any way to have your heads checked to see if they are made from the defective material? I got an August 2010 build but plan on keeping the truck for 200,000+ miles (if it doesn't drop a valve)

The only way I have heard of is to use a bore scope to look at the valve faces. I would think there would be too much carbon on them to see any hair-line cracks, but maybe it's possible?

My truck was made in may 2011, so it was made after the march cutoff. This TSB is enough evidence in my mind to justify not changing the valves while I'm replacing my dead turbo. If it weren't for this TSB, I'd very likely be tearing the whole thing down and spending at least another $1000 on the job to replace my possibly defective valves. As it sits, I'm already spending about $3700 to replace the turbo with a good aftermarket one and put a good fuel/water separator on it.

Another bit of information, the heads have been redesigned. I don't know if this is related to the valve failures, but it could be. Maybe they went to thicker stems? The engines with redesigned heads started to be put into trucks sometime in February 2012. This information came from the rumors about a head redesign and that the ford parts sites like tousley ford show that the current part numbers for the heads work only for trucks built before that date.

So there are replacement heads for trucks like mine with the higher chance of failure? I'm guessing a head swap is a cab off job and will not be cheap?

Oh, yeah.
My cup holder broke & they told me I get a new motor.
When I picked it up I found out I had a new tranny too.

Title on hand like always
