Spark Plug came out!

[Sir WIll]

Arrrrrrrgh!

Driving this morning and the engine light came on, stopped and used the code reader and got ODB 303 for a misfire on cylinder 3.

Now I have no idea how this has happened but the plug has worked itself out and fired itself into the coil pack destroying everything!



Trouble is the thread in the head has been damaged so I cannot get a new spark plug back in!

How much of a headache is it to repair the thread?
