Hello, I took out my spark plugs last night to check them since I am looking to fire up my Z for the first time in 5 years or so. Here was my dilemma that popped up though. I was putting spark plugs back in and all had been going fine, until of course, the last one I was putting in: #6. So I noticed I had put it in only a few threads and it seemed tight. I looked at the plug and it looked like it was a little off center. I took it out and tried to put it in again. It did the exact same thing. I looked at the chamber and it looks a little messed up. If something happened to the threads, since this happened with two other plugs as well, what are my options to fix this? Any ideas? Thanks SuDZ
