2005 F150 - #7 cylinder plug issue
#7 plug come loose and was barely threaded into the head. I pulled the plug and you can see the top of the plug is missing. The plug is the OEM Motorcraft replacement and was only 6 months old. Use torque wrench when installing. Any ideas on how to get that metal top out of the cylinder? Would a shop vac work?

Are you certain the piece is even in there? It is very likely that it was broken up and blown out the exhaust.
Personally I would be borrowing an inspection camera and having a look inside. If it is still there I would not start the truck but attempt to use something to get it out. Use a wrench to get the piston to TDC and then something like this to get it

I had something similar, all 8 plugs broke and during extraction all the electrodes were snapped off and there was porcelain in the cylinders as well.
I wanted to be sure 100% that I didn't get anything in the engine that I couldn't get out(I blew it out best I could with compressed air and also shop vac). I still didn't think it was all out. I definitely recommend getting some kind of inspection camera.
I bit the bullet and had it towed to the dealer, and $800 later they cleaned out all the cylinders for me. They used a camera to inspect every cylinder, and either blew out or vacuumed out each cylinder to get out all the pieces and verified it was all out, I think it was 7 hours of labor or something like that. They told me there was still a bunch of parts in there when I brought it in.
If I had to do this again, I'd buy a camera, and attached a small hose to a shop vac and inspect, vacuum, inspect until you see nothing. For $800 I could have bought a camera.

I got an endoscope off amazon that is wifi and uses my iPhone for the screen. Not bad for $35, but I can only see down into the cylinder and not up towards the valves.
Take a look at the images I took, is a valve supposed to be in view while looking down into the plug hole?

Thats some serious blow by on that plug
It acts like a blow torch or a cutting torch. Yep -torque those plugs in 25-28 foot pounds not by feel .
You are looking at a piston-- the valves are in the head . Your camera would have to be turned around 180 degrees to see valves .
I would guess the burnt parts of the plug have been pushed out the exhaust . I have used a vacuum tube to pull out broken plug parts on first oem plug change . But after all those cycles I would doubt anything left in there that you could get out .
You should replace that boot for sure .
