Help! Spark plugs!

I decided to change out my spark plugs today, and everything was going smooth until I got to the last one. It took me about 10 minutes to finally get it out. And when I pulled it out, I noticed some kind of metallic compound that was at the end of the threads (look at attached pic). Anyone know what it is and why it was so hard to get out? It also left alot of metal shaving behind in the cylinder (pic).

Thanks,
Jacob

I am on my phone so I can't tell but it seems like the tip of the spark plug was stripped. This explains the metal shaving and why it took u forever to remove that plug.

In the future, use some anti-seize compound. Also...check the spark plug hole and see whether the thread is still good

I hope this helps. Good luck

you are welcome.

do you have any update for us? Was the spark plug housing thread damage at all? I just hope that it was just your spark plug itself and not the engine
