    Changing turbo headers out, Had to remove water galleries to reach nut on header flange.

    The Water galleries at the banjo fittings on the Turbo were full of grim/sludge (would have thought it was an oil line) . Is that due to leakage in the turbos over time or a result of the engine head gasket failure?

    IB ?????

    Not running coolant (only water) for a while would cause that.
