Answer
What you have is the common fault of engine coolant getting into the combustion chambers due to faulty head gaskets. There is a manufacturers service bulletin addressing this problem and the fix is to drill out the head bolt holes in the engine block and install heli-coils in the head bolt holes and install larger head bolts. My suggestion is to replace the engine with a REMANUFACTURED ENGINE which already has this head bolt modification.
