On the saxo i had, sometimes when it was cold you would hear a slight tick from the injectors as they are quite noisy on the saxos | |

Probably just noisy lifters, untill it starts doing it all the time i shouldnt worry about it too much! | |

sounds like its from the top of the engine although i cant be sure, and it doesnt really sound like any rattling trim although i'll try removing heat shield to see if it goes cheers | |

Did you get the water pump changed when you got the belt done. This might be the case as i have seen this knock/click before until the engine heats up. | |

if i give the throttle a little blip it goes away for a few seconds then when it gets back to idle it comes back | |

well a rattle then, it sounds slightly like the noise the engine makes when your about to stall but much fainter | |

You sure its knocking.. Knocking is caused by worn big end or main bearings and if anything it will get worse when warm and louder when you rev. | |

my saxo has developed a very slight engine knock/rattle on idle when i first start it, seems to stop once engine is warmed up and its so quiet as soon as i rev the engine i cant tell if its still doing it. |
