I'm just not sure that was a screw. Based on the piston width of 3.74", the object was approximately 1/4" in diameter and 1/2" long, with a somewhat pointed or rounded end. The "threads" really are not pitched, but more like annular rings. And I'm not sure what is going on at the bottom of the piston. Is that a hole or a shadow? If a hole, is the object down in the oil pan?

Hi Jack, when I said "self tapping screw", I really meant self-tapping but with a nut-driver head....the type of fastener that is normally used to join sheet metal ducting or fasten plastic components to each other or to the firewall, etc. (But of course, the head is gone, if that's the right description of the object, with only the threaded portion remaining)
The "hole" is just a shiny reflection of the piston dome. There wasn't a hole that I could see, but I didn't scrape it. I'm still holding out the hope for an actual Ford diagnosis.
