tapping sound

  1. #1
    okay so was on the motorway today and heard a tapping sound...

    engine was up to temp
    happens in all gears
    happens only between 2500 and 3000 rpm
    happens when the accelerator is about 1/3 of the way down

    i thought it could have been the wind rattling something, but it stops if i push the accelerator more or let off.

    any ideas? known problems? or am i just over reacting?
