that's a steel thread repair insert. remove it from the spark plug that it came out with ..( or get a new insert ) put anti-seize compound on the threads of the new spark plug ( as all spark plug threads must have ) screw the new plug into the insert. and use the new spark plug as an installation tool I would put lock tite on the outside threads of the insert to hopefully stick it permanently into the head. I'd tighten that spark plug properly, but I wouldn't overtighten it for sure .. or the insert might just come out with the spark plug next time. scott tuirbovans hoping this only posts once ----- Original Message ----- From: "Harry Hoffman" <hhoffman@IP-SOLUTIONS.NET> To: <vanagon@GERRY.VANAGON.COM> Sent: Tuesday, November 02, 2010 1:52 PM Subject: spark plug threads
