Remove broken spark plug in 2008 Ford E150

Durham NC

Description

This is a 2008 Ford E150 with a 4.6 and the plugs are known to come loose. This plug (closest left on inside of vehicle with cowling removed) seemed to be loose (which is common for these), so I was removing and retightening. I was able to get the others out fine, but this one was stubborn. I thought I had it out as the socket started turning (pushing my foot on the ratchet for leverage) but I may have rounded off the plugs 5/8" top. I'm not sure this is the case but the pic from my phone seems to suggest that happened. To me the only way to get this out is to get maybe put a little Epoxy puddy into a 5/8 socket and put it on the plug - wait a day and try again. Any other ideas? How mucy would you charge to get this out. Thanks, Richard
