    Hi Guys

    Am experiencing a rattling noise from the left side of the car. It is clearly aubidle under accelaration starting at abt 2000 rpm getting louder between 2500 and 3200 and then getting quieter and not aubidle anymore at abt 4000 rpm (maybe because Tubi voice take over....). It is louder if do acceleare in 5th or 6th gear from low RPM. it is only audible if the car actually move. If car does not move, i.e. do accelerate with the car standing no rattling audible...
    Car has 46000 km, cannot be anything with the clutch since it was replaced some 900 kms ago, including pilot bearing, shaft bearing, Hill engeneering Throwout bearing etc etc. It rattled before and still rattles after.
    Oil pump timing chain or oil pump bearings or belt drive gear bearing ?
    It sounds indeed as someone would shake a bearing with loose cage. Why only audible if the car is moving ?

    Tks for any help.
    Gianni
