Help. My Fit GD at 126000km IDSI. Have a clanking noise when RPM runs at 1.5 to 1.8rpm. But no noise at 1rpm & 2rpm while driving. Even on full stop and revving up, no clanking noise also. I already replace Sparkplugs, Air Filter, Cleaning Throttle Body / EGR Valve and also replace CV joint assembly. This clanking noise just started when I service it for replace Oil Seal, Thrust O-Ring and Change oil it to 5w30 because of leak problem. Right now I change my oil again (6500km run on 5w30) to highmileage oil 10w40. My Engine little quitter than before, Because I read some article to try thicker oil. Is this problem can be solve by Valve Adjustment ?
