    On sunday my S3 decided to let me down, was driving along doing 50mph when what felt like a miss fire, happend a few times so i pulled into a layby, when i got out there was a nasty loud tapping from my engine,

    When i got my S3 as i do with all my other 20v engines i have owned i dropped the sump cleaned it out
    and this one was quite bad so i put a new oil pump and replaced the big end shells cleaned the oil ways though and put it all back together,

    it has oil presure but the noise is very loud seems to be comming from the rear right of the cam cover as you look at it,

    I got the RAC to recover it but not had time to have a look as yet,
    Any one got any idears or had same thing happen to them??

    Thanks

    Woody

    chain tensioner failed and chain making a racket on the cam cover?

    what does the noise vary with?

    Ye,
    I would get the rocker cover off and check the chain and the tensioner between the cams,

    Mate, I know the feeling believe me. However, keep at it. It's not the end of the world, just a hiccup on the path to peaceful motoring....
