On our 1973 plus 8 RHD it seems as the core plug at the inlet manifold - between the two SU carbs- is not tight. Even if the engine has not been on for some time, water is found at the plug, which is concave and hence acts as a small bowl. Is this common and what to do about it? Guess it has to be changed but can that be done without major disassebly work and how to do it? And why are there (cooling) water at the inlet manifold? Is it to cool down the air/fuel mixture to gain more power? Cheers /Finn
