Hi all, reunited with my beautiful ZL after 2 years! Fitted manual tensioner and what a difference! Anyway, I'm concerned about a squealing sound coming from the motor, sounds like cam area.. All rpms, idle too.. I'll see if adjusting the tensioner makes any difference.. Could have been there all along who knows, rattling chain made such a noise. Runs great otherwise.. Going to check oil today. Any ideas? It's not super loud but def audible.. I'll try post a video later..
