I JUST had the same thing at 85,000 miles.
It is the heads. Ford did not use steel valve seats. They're just cast into the head, dumb Idea.
It can't be fixed you have to change both heads. The replacement heads have steel seats.
Ford will not cover it they did send out a service memo to their dealers.
It is #4 and #8 that go bad. You getting off cheap I paid 8 grand for new heads installed. I kept the truck, I just put a $3000 deer bumper on.
A, 2" lift, Airbags in the back winch on the front, and a lift crane in the back.
