    Thick White Gunk!!!!

    i have been given a shed of a mk3 to get me about in a i was desperate for a car. check oil and water etc today only to find a thick white gunk all over the dipstick and on the inside of the oil filler cap and inside the engine doesnt look to good either.
    what do you guys reckon could be causing it?

    im not the most knowledgeable about mechanics so any ideas and help would be greatly appreciated.

    Hi mate,

    Head gasket is the cause and you should get it looked at ASAP

    Not always true, although coupled with overheating and water usage sounds most likely.

    But i have mayo on mine all the time, down to the fact it's an 8v and i only do little trips. According to my source anyway

    look at you go!

    And she's right. If it's using a lot of water and overheating quite a bit, it's quite possibly the head gasket that's going. It would be wise to get it checked out as soon as you can. But, if it's not drinking *that* much water and you only do short journeys most of the time, then it's pretty common and nothing major to worry about - just give the car a good long blast every week or so to help clean it up

    I agree with what has been said above.

    Your going to be looking at...
    New head gasket
    Skim
    pressure test
    Perhaps flush for the system
    Thermostat

    Whilst your there you may as well ...
    Change the cambelt, rollers, tensioners
    Water pump
    Full service.

    Yes it may cost circa £500 but your pretty much looking at 40K trouble free motoring. Unless you feel its not worth it in that case couldn't of come at a worst time as scrap values have plummeted recently in Brum. Not sure if its the same country wide?

    Welcome to AOC sorry it couldn't be under happier circumstances.

    having had a few mk3's (and also having experienced 3 munched head gaskets over the years, 1 in an ancient land rover and 2 in my first mk3 due to it not being correctly repaired the first time) it could be either of the above, but given the weather it is most likely just condensation sludge if you are doing short trips in cold weather, as it is a very very common thing on the mk3 engines.

    Take it for a good long run, it'll either clear it or kill it LOL. Either that or get your garage to take a look. Compression test ought to show up if there are any breaches in the head gasket around the cylinders.
