    I'm not exactly sure the noise you are trying to describe, but I'm thinking mine does the same thing. All 465's are noisy to some extent. All the ones I have driven make kind of a soft grinding noise at idle with the clutch out, but they still last forever. Or is yours really loud???

    Mine makes a sound like that. In my case its the spring resonating to the vibration of the engine at idle. So I put a piece of black plastic electrical wire conduit around it. The sound stopped right away.
