    It doesn't sound good..

    Are you able to work on it yourselves..??

    Sounds like you've lost #3 piston, this will likely include #3 cylinder liner..??(hopefully not)

    If the heavens are on your side you might get away with a piston and a hone on #3 cylinder..

    If your gonna repair it youselves the next step will be getting some pictures up..!!
