Is200 Ignition Coil / Spark Plug Destroyed

[Giggitty]

Think I am facing a total disaster here with my 2003 IS 200 SE.

Had a misfire yesterday so went through the process of checking spark plugs. All were OK until I came to the 5th and when I pulled out the ignition coil, only half of it was left and it was quite clear that there had been some sort of 'short'. As a result, the top of the spark plug is all but gone and I cannot get a socket to the bottom of it to get it out.

Any ideas on how to proceed? Have tried using a bolt extractor but there is nothing for it to grip onto. Will drilling into it with a screw extractor work?

Only other option as I see it is to remove the head but would like to explore all other options before going down this route. I can also imagine that putting into a garage would probably end up costing more than the value of the car.

Any guidance or tips would be greatly appreciated.

Hi mate, I dont know if that will work, but what I would do is drill into that spark plug, tap it anticlockwise, put screw in it and try to take it out... I havent done it myself but hope that might give You an idea.

Just to make sure that, You will turn engine after so all the metal bits will get of the cylinder. Hope that helps

what is stopping the socket? You should be able to break off any remaining ceramic allowing you to get the socket on it - or has the metal part of the plug been damaged as well?

I'm thinking the same, if the coil pack/spark plug cap has broken up chances are bits have fallen down around the plug preventing a plug socket from fully reaching the plug hex.
