My father has a 95 Mystique with a 2.5. About six months ago the water pump went out. Since that time he has been getting coolant on the plugs and bubbles coming up in the coolant. Are these engines bad about blowing head gaskets or cracking the heads. Also can you remove the heads without removing the engine. The only replacement engine that he can find is in 99 Cougar. Does anyone know if this will fit. He was told that we would have to change the intake manifold and use the one off of the 95. Thanks Larry
