Good afternoon, my head gasket job (1991 300te 4matic) has been going 'so far so good' but just before I remove the head I have run into two wee problems.
1. My chain rail pin tool does not fit. Where in the world can I source the correct sized tool, or can I make one?
2. My chain tensioner inner threaded ring looks like a 17mm xzn fitting WTF?
