Good luck! I hope it works out for you. You might need to get a little creative because of which plug it is. Mine was the driver side rear plug, it was a little tough to see but in the end it worked out.
To repair a spark plug hole make absolutely certain that both intake and exhaust valves are closed, you DON'T want to run into them with the tap. That would be a very bad thing.
Use grease on the tap and after you are done, put a long metal tube on your air gun feed it into the spark plug hole and blow out any remaining chips. No a vacuum won't work!
