Default Re: Drivetrain noise

Its an old thread, but I think I figured it out... Turns out the steel wire clip that secures the clutch fork onto the bell housing clutch pivot ball was missing. With the new engine, I've installed a new clip.

I think this caused the noise due to the fork vibrating at low RPM. The clutch adjustment kept the fork from coming off. When you touched the clutch pedal the noise went away.
