    Hello all
    Couldn't find this exact problem elsewhere on the threads - have the above noise on initial acceleration/throttling/moving up through the gears (automatic). Tends to stop once in 4th, with the odd rattle at cruise speed. It's done 170k and I'm concerned it may be the timing chain. Does anyone have any experience/knowledge of this please? much obliged.

    It could be the cam actuator. Get a Merc tech to listen to it.

    Or the belt tensioner and damper.
