    Hi

    Got a 99 206 XS and its running fine but... The engine has started to
    make an odd knocking type noise that you can only really hear on idle as
    as soon as you start to move off the road noise drowns it out. It makes
    no difference if the clutch is depressed or not so its not the gearbox
    and it also increases in 'speed' if you blip the throttle. There is no
    smoke on overrun and and no loss of power etc. It has not really got any
    worse since it started about 600 miles ago but i want to find out what
    it is. Oil levels are fine etc.

    Any ideas on this one as i am stumped - If i were to guess to me it
    sounds a bit cammy but as i said thats a guess.

    Any ideas?

    thanks

    thanks for the tip - car has only done 67k so i would not expect
    something major like a bottom end going so i hope is not that!! Would
    the water pump possibly make a noise like that? It has pas and air con
    too so i guess it could be any of those....

    If it’s diesel it could be an injector on it’s way out

    thanks its a 1.6 petrol

    its now solved however and turned out to be a loose spark plug! I guess
    th blow-by was causing the sound that was exactly like a major bottom
    end woe!

    mechanic could not diagnose it but in the end after lots of tinkering i
    figured it out.
