Is it okay to drive with a blown spark plug?
You shouldn’t drive with a blown spark plug and since you probably can’t get it out because the heat has welded the spark plug, you need to remove the coil and the inductor wires from the blown spark plug so that way that particular spark plug is disabled and won’t do damage to the engine.

Can a blown out plug on a TIME SERT be repaired?
The only damage a blown out plug normally causes is either a Time-sert or Heli coil is installed to repair the threads. I have have found the ear broken off of the coil in engines with “coil-over” plug configuration. But I’ve found these can be fixed if you want to take the time. I suppose there could be other freak damage, but it’s unlikely.

If a spark plug blew out of a head, it usually means the spark plug threads in the head were ripped out also. And since these are aluminum heads, this is probably what has happened.

What causes a spark plug to blow out in a Ford?
Ford 4.6, 5.4 and 6.8 modular engines are prone to spark plugs being blown out of the cylinders due to the aluminum threads failing. If the spark plugs are not tight enough the spark plug vibrates until the aluminum is weakened to a point the spark plug shoots out.
