    Hi
    I think i have some damaged valves due to a broken camshaft sproket.
    Does anyone have any idea how much this would cost to fix, just a rough
    estimate. Or how long it would likely to take a mechanic. the car is a
    peugeot 306 xsi. 97
    many thanks

    If the valves are damaged it'll be because they've hit the tops of the
    pistons and been bent as a result.... meaning the pistons also likely
    to be damaged; so too are the vale guides, in fact this kind of event
    can be fairly catastrophic. You'd know if they'd hit because the noise
    would have been dreadful and the engine would now have very poor
    compression and run poorly. I'd guess it would take a decent mechanic
    at least a full day's worth of labour to sort, maybe even a couple of
    days, assuming he simply does a complete cylinder head exchange,
    replaces pistons etc... but along the way you'd have the costs of the
    new parts plus re-grinding the cylinders etc. You're probably looking
    at some serious costs here, maybe more than the vehicle is worth and it
    may be cheaper to get a recon engine. Before doing anything check the
    compression (or get it checked). That'll give you a fair idea of any
    damage.

    Hi
    The car started then shut down after about 2 seconds. The car was not
    moving and there was no noise at all from the engine. the camshaft jammed
    which broke the sproket and now the car wont start just turns over. any
    help many thanks.

    first port of call is a new timing belt then cross your fingers
    as the rule the pistons normally survive the impact but not always so the
    valves
