Hi everyone. My mechanic could not remove spark plug #8 he said there was a washer or something stuck in the spark plug well. I took a look myself but I can't seem to figure out what it is, I don't want to take out the spark plug and have that fall in the cylinder.

I took some pictures so if anyone knows what it is or if its safe to take out the spark plug please let me know. Thank you!

 

Whatever it is it shouldnt fall into the cylinder. As it looks it is wider then the bottom of the sparkplug so since the nut part of the sparkplug is bigger then the threads i can make an educated guess that you are safe to remove it.
But the other choices are pull the head or leave that plug in there.
