    The tell tale signs are coolant gushing out from the expansion bottle, if the head gasket has gone, or a severe oil leak to the outside.
    The cost depends on whether the cylinder head has to be machined flat (£60 approx) and most of a day for the work plus parts.
    An independant garage should give you an accurate quote.

    Probably just due to cold, short runs......engines produce lots of water / chemical condensate and usually this boils off (or it should in the summer). However, as the engine rarely gets scorching hot, this condensate condenses ( :p ) at the coolest part of the engine, i.e the rocker cover. If you were to take the cover off, you'd see loads more inside!
    In the good old days, this condensate vapour was allowed to breathe away outside, and then someone had the bright idea of routing it through the air cleaner, where it choked up the carb and filter :D
    It has to be burnt nowadays to prevent pollution.
    So - check the coolant regularly, wipe away the grot from the oil filler cap from time to time, and worry ye not.
    P.S Diesel drivers will be smug here, as its only the petrol engines that are really affected :p

    Only by unbolting the rocker cover, lifting it clear and wiping it mate.....although you could ignore it! Most petrol cars have this for years, and to be fair it doesn't do any real harm, although it sometimes clogs the breather pipes up.

    rocker cover is usually the cover around near the oil filler cap, covers the tops of the cams.

    depends on the car but on the girlfriends 206 it's a 20min job, remove a selection of bolts and a breather pipe then it's clear to clean.

    not sure on the Corsa

    p.s the usual test for head gasket failure is a colour changing liquid you put in the coolant to see if exhaust gases have found their way into it, if they have then the liquid changes colour
