blown spark plug
The insert driver (Roll form tap) seats the insert
and completes the bottom threads.
This pushes the pin out to contact the threaded
hole. Back out of the insert is prevented by the
cam lock effect of the pin.
This is an example of a step by step repair. (1) Start the step tap into the hole to be repaired.

(2) Use the wrench and tap new threads. Continue to tap through
until the cutting edges are approximately 1/4 inch below surface.
(3) Leave the step tap in the hole and place the seat cutter over the shank.
(4) Using the wrench rotate the seat cutter. After a few turns lift the seat cutter
to inspect the seat. Repeat operation until the seat is completely cleaned up.
Back the step tap from the hole thus removing any burrs from the top thread.
(5) Make sure the hole is clean and dry, Screw the insert
onto the prepared hole.
(6) Lubricate the insert driver tool, Using the provided wrench rotate
the driver through the insert. When the insert is seated the driver
will tighten up, With increased pressure continue to rotate the driver
until it loosens up, Then back the driver tool out of the insert.
(7) Repair is complete. Solid steel threads are square to the
reconditioned seat, insuring a good spark plug seal.
The repair of spark plug holes can be done without removing the head providing
you have enough room to access the tools in the kit. Grease should be applied
on the flutes of the tap in order to catch chips from droping into the motor, repeat
this process several times with the grease to prevent any stray chips from falling
into the motor. You will want to blow out any loose chips by removing all spark
plug wires (so engine will not start). Then turn the motor over to blow out any stray chip.

I have the kit. No need to go out and buy it if you do not have to. I have offered this kit out a few times to the others that have had this issue.
All you need is to get the correct inserts for your motor.
PM me after you see what the dealer does. This is not a new problem, and Ford does not offer any kind of recall or anything. We're stuck.
