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:
