    Nasty Noise

    There is a horrible rattling noise when you rev the engine/driving along the road in high revs when the engine is cold, and theres quite a bit of steam/smoke coming from the exaust. When its at normal temp, seems to sort of dissappear. Any one have any ideas?

    Unsure of the acutal engine name, but its in a mk4 1.416v.

    You checked the CAT? sounds like it may be breaking up.

    unless the belt lets go. no.... well not really.

    In a farsical world it could stretch and slip the timing out far enough to let the valves touch the pistons, BUT thats one hell of a lot of stretch and less likely to happen.

    The cam belt doesn't have to break to cause damage, I had one which shed a lot of it's teeth, luckily I had an engine where the valves didn't kiss the pistons so I got away with it, this is not the case with the Astra engine.

    Get the belt changed asap, fit a new water pump as well as the noise could well be the pump breaking up.

    Don't wait, do it now. Bill for a cam belt breaking is enormous.

    MIne cost me £65 inc parts but I did it myself average is around £200. You should have asked for a price beforehand or they can take advantage of your ignorance.
