Anyone seen a coil pack melt like this?

So I got a phone call from my mum yesterday who said her engine light came on and car suddenly had no power and was misfiring badly

 

So I got the car recovered back to her house and decided to have a look

 

Noticed straight away one side of a coil was bent up so I undone the bolt and the top of the coil was no longer connected to the rest

 

Rocker cover was burnt on top from the sparking where coil was broken I guess

 

The rest of the coil was completely melted into the spark plug, after 2 hours of removing we got to see the spark plug which literally looks like a piece of charcoal and is crooked and raised out of the threads so I can’t get a socket on it to remove

 

The only thing I can think of is the spark plug has backed out and serious heat from the combustion chamber has melted everything

 

Any other ideas?

 

Here’s the coil after removal

Here’s what I had to remove, can see how black the tube is in the head from the heat

And this what the spark plug looks like inside the tube, I’m yet to try and remove this

The tip is completely off and wedged down the side, spark plug is also against the tube so I can’t move it or get a socket on it

Some serious destruction right here [emoji23]

 

Just hoping the bottom of the plug is intact and hasn’t broken off
