I started today on removing plugs on my 2007 5.4 .I read the ford tsb and the forum for tips on what to do I backed the plugs off about 1/8 to 1/4 turn poured the cleaner down the holes let set for about 1/2 hour.Started on the passenger side front plug worked it back and forth and got it out intact then the next one I backed it out but when I went to pull the plug out nothing, even though I backed out all of threads until it was spinning freely.I look down in the hole and see the porcelain is all there with the tip, the plug won't pull out even if the ground shield is stuck with the porcelain shouldn't the threaded section of the plug with the 9/16 hex come out?so I wrenched it back down and it tightened up just fine so I backed it out again and just spins freely.In all of the TSB 's and forum tips I have not seen how to get the threaded piece out.Please any help appreciated.Maybe a magnet?

 

Can you pull it out with a magnet or a very skinny needle nose, or put a little bit of shop towel in your socket to make it a tighter fit?
