Weird rattling noise

  1. #1
    My saxo VTR has developed a strange rattling sound when accelerating. The noise is not there when the car is in neutral (or in reverse bizzarely) but it's really irritating, and sounds like it could be damaging to the engine...

    I have no idea what it could be, but like I said it's a kind of rattly/tappety noise but only when the clutch is up and I am accelerating in a forward gear, but it's only started this weekend.

    I have changed the oil this weekend too, but it's still doing it, any help or suggestions of a possible diagnosis would be greatly appreciated! =D thanks guys!
