Hey guys, My car was basically completely rebuilt by Otto's in Venice Beach. John always told me that he adjusted all valves to 0.004in, and he's been doing it for years, never had issues, and feels its a better setting. I believe his comment was, "if you can hear them, its bad" Otto's isn't convenient for me for regular visits and the guys I've been using do not want to do that. They all want to use the factory settings: INT-0.006in EXH-0.008in After an Otto's adjustment, the valves are nice and quiet. After an adjustment from anybody else, they still sound noisey. Now, Otto's built the motor and heads originally, and I do feel some trust towards John. I know that he's got his own methods for head rebuiling, but has anybody else experienced good or bad either way?
Should I force my mechanics to use the 0.004 settings anyways, or should i let them stick to the factory recommended settings?
Thanks for the advice. Jonas
