    Default Is this head gasket failure

    Hi guys, well after having oil getting into my coolant I decided to do a compression test.

    From left to right as you look at the engine bay, the results were 14, 14, 14, 12.5 , does this mean gasket failure on the last one ?

    Thanks very much

    Hi

    Get a sniff test done at a garage.

    or

    Use this
    http://cgi.ebay.co.uk/UNIVERSAL-CYLI...item3cb704f255

    A compression test wont always show up a leaking gasket,
    as you have already said
    " oil in the water"
    and not water coming out the exhaust or compressing/boiling the water system.

    Hi mate I got a sniff test done and they said it was fine, but then I was told to do a compression test as the sniff test doesnt always show up signs either lol.

    I did notice this morning some water coming from the exhaust, and I also stuck my finger in there and it was black as hell, not sure if that is just build up of things or what.. ?

    Thanks

    Hi mdibb and welcome,is the cooling system pressurising,if not you probably have a leaking oil cooler,as the oil pressure is greater than coolant pressure,oil will enter the cooling system,the oil cooler will need pressure testing.
