    WTF is this noise coming from the block... please helpppp

    Hey guys,

    Drove the car last night just fine, tonight I start the car and I am greeted with a screwed up noise coming from the engine.

    Please listen to the sample.

    Does anyone have any idea what this noise is?? I quickly recorded it and turned it off.

    Thanks

    I've never looked at a VW timing belt but have worked on heaps of Fiat's, Lancia's and Alfa's
    The timing belt does always not run in the dead center of the wheel
    If there was a problem it would be off the wheel quicker than Tony can put his foot in his mouth

    Listening to the audio recording,
    there is a rapid and high pitched sound similar to parts interfering, it is concerning
    Is this a manual - what happens if you push the clutch down? (checks the release bearing)

    Here is an idea that may help - it's a bit daggy
    Get a piece of wood - a broom stick or something
    Press it against the water pump and then put your ear against the wood
    Wood conducts sound really well and you will know when you've located the source
    Next try the alternator

    Not much point putting it on the head or rocker cover as there are heaps of moving parts all making sound there
    You need to know what is normal and what is bad to make sense out of sounds from that area

    You really need somebody that can help to have a look at it - take it into the workshop

    Oh really?

    The only reason I thought it was unusual is that I found an image of a passat 1.8t, and the timing belt is 100% on the sprocket....

    That timing belt is the same width as the wheel - it would be in trouble if it was partly off the wheel
    When the belt is more skinny than the wheel - it could be left/centre/right

    as always internet diagnosis is careful guessing at best for most - martin's suggestion of taking it to proper help is best.

    Let us know how it goes
