It's not normal. That's the Ford Engineers telling the service department techs to do nothing..hoping it will, or you will go away.
If your current dealer will not do anything, call Ford, and asked to file a complaint for defective product. They will assign a case number and contact to work with you and a dealer to resolve the problem.
GET EVIDENCE...the videos I made were the smoking gun, that nobody could answer and could say that it was "normal". Also, if you have time, take it to an independent shop to make a diagnosis, and get it on paper. They do not need to fix it, but just have it so that Ford knows that it's been seen and another professional has determined that it is not normal. You will need this if you enter into any litigation or buyback.
Go to a different dealership. Don't tell them what you think is wrong, just that you have this noise. The best thing...is take it into them when it's making the noise and get them to acknowledge it, and get it written down. If they refuse to look at your truck, at the very least get them to write down that they are refusing service - another big thing to have.
Bottom line, get them to hear the noise, and ask them to shut down one cylinder at a time and see if the noise goes away...it has to be making the noise first though... Mine had to be HOT...
The noise comes from the cylinder being bored oblong and the piston/rings etc are sloppy..allowing the knocking noise. It will get progressively worse. There is no TSB on this...
Don't let them bully you. You paid good money for your truck, it should run as designed!
