As suspected, there is no PCM 'Recalibration' Fix for this issue, it is a complete rebuild of the head, and if you are going to go that route, you best insist on an entirely new head to save yourself further grief.
As usual the dealers are somewhat in the dark. I am sure more clarity will come shortly.Why do you say there is no PCM recalibration? The first step in the TSB states to update the PCM to the latest calibration...
Then they perform the exhaust valve replacement. This goes along with what you and I talked about.
1) If they don't have the issue, the PCM update will prevent it from happening.
2) If you do have the issue, they still have to replace the exhaust valves and update the PCM with the latest update to prevent it from happening again.
So after having some episodes jackhammering last year, the episodes go away in the winter. Seems 70f ambient temp is the threshold. I now have almost 20k miles of no regen issues, can I assume that my engine is 'worn in'' and outgrew the jackhammers? Just passed 40k today. I guess I will know as summer temps come in.Yes sir, most likely. If you can get in that mid 20k to 30k range, enough wear in generally occurs to allow for the thermal expansion, seems to be, the in the clear Mark.
A lot of us with the issue have some sort of monitoring device, I have a edge insight. It absolutely takes any guess work out of knowing when and how long they occur. It's basically like having a countdown clock. So when it starts just going into tow haul mode is enough. But I've pinged in that and still had to gear down.Not a fix, but a workaround: I've heard that shifting down a couple of gears to keep RPMs up eliminates the hammering for that regen. If you know a regen is coming, perhaps a lockout of 6th or using Tow/Haul would get you through it. After a few thousand miles of this inconvenience, the clearance should open enough so the work around isn't necessary. I am open to comments on this as I am thinking out loud and now have 24K on my truck without the issue. It would at least give you the power of getting involved in reducing the impact and not just feeling helpless.
There was plenty on this forum. TSB: 13-05-09 Was the first tsb ford put out that I remember for this issue.
Absolutely correct... the issue was not present in the 2008 - 2010 trucks with Regeneration, but first started showing up with the 2011 - 2014 and then intensified in severity with the changes made to the 2015-2016 engine.There was plenty on this forum.
