    As the title, looks like my head gasket is on its way out.

    Out and about today shopping, the low level coolant sensor came on, was on the motorway so pulling over wasn't really an option, after 10 - 20 seconds it went off and didn't come back on, thought fine, maybe playing up.
    Got home, washed the car inside and out earlier, thought why'll im at it ill check the coolant and change some 8mm silicone id fitted for 7mm as it seemed to have been weeping.
    Checked the coolant and it was well low but it had a section in the corner that was quite brown. Changed the silicone coolant pipe and when i pulled it off, there was oil in the pipe, i say oil but i cant be a 100%, it definitely wasn't coolant, it was too oily in feel and dark.
    Checked the oil and it was fine all be it a little low.

    Thoughts gents!!!!

    Yup, thats the strange thing, hendo my vauxhall mechanic mate brought home a tester, one that you unscrew the header tank lid, bung it in and it changes the fluid if exhaust gase's etc are present, came back fine, thats was 3-4 months ago though.

    Whats your thoughts sandip, i know your the HG expert these days lol.

    I bloody hate cylinder heads and gaskets lol

    Top the coolant up and if the level starts to drop i'd get another sniff test done and if that doesn't reveal anything maybe a compression test.

    Maybe it's time to put that largeport on :eyebrows:

    Well going to keep an eye on it, there's also another silicone coolant hose that's a suspect weeper but didn't have time to change it, that's a job for in the week.

    Haha already thought that mate don't you worry :). Just means my respray money will get spent.

    No idea, if it was oil i think you'd know about it as it would be quite frothy

    Let me know when and where this meet is :)

    You meaning the posty dan?
    The thing that happens sunday evenings?
    Also, the slimey stuff in the hose... could be very old antifreeze?
    I had a water hose go on mine a few months ago and to be fair the slime it left on top of the gear box was worrying but turned out to just be whats normaly inside the engine making its way out ,
    I would flush the coolant system and then refill with fresh clean coolant, That way you know where you are with things and can keep an eye on it from there.
