    I have an Astra 1.6sxi on 03 plate with just over 6000 miles on the
    clock. When changing up the gears I've noticed a metallic rattling
    sound that occurs very briefly. I can get the same sound if at low
    revs ( 1200 ) I go from no throttle to my foot flat to the floor in
    forth or fifth. I've only noticed it recently as I've had the window
    open in the hot weather, you cant hear it with the window closed. As
    mentioned it's very brief if a little disconcerting. Anyone else get
    this noise? The car seems to run ok. As it's still under warrenty
    thought I'd check here before taking it to a dealer and hearing the
    immortal line 'but they all do that sir...'

    As a follow up, a friend who had not seen the car before thought it
    was a diesel! I had not noticed before but it is rather noisey on
    idle, possibly the tappets. Along with a sort of breathing sound.
    Booked in to Vx for Wednesday, hoping its not too serious....

    I had the same similar noise too in my 1.6 16v Club V plate and that was the
    tappets. The Vauxhall dealer just flushed the engine and stuffed magnitec
    oil in. The noise was still there though even when that was done. When you
    first fire the car up from cold is when you hear it the most before the oil
    gets thrown around the engine. Its normal apparently :)

    Had car checked over, apparently no problem with it. The noise is
    coming from cam belt area, and apparently is normal for an astra.
    However as its under warrenty they are fitting a new cam kit so try
    and quieten it down a bit. As for the rattle when changing up the
    gears, its pinking. A 'feature' of the 1.6, as you lift off the
    throttle the ECU backs off the mixture, as you accelerate again the
    mixture is weak and so for a brief second it pinks. One final note,
    the fuel line was tight on the body work. The noise of the pump was
    resonating down the fuel line which in turn went through the body work
    making the engine seem loud inside the car. Moving this has quietened
    things down inside.

    Check the clips which hold the top of the air filter. We had on in once, and
    the customer was complaining of pinking; turned out to be a rear clip
    rattling against the bodywork.
