I took my 355f1 for a track day . After the 5th laps the temperature gauge light blinked due to overheated engine. Soon as I reached the pit, we check the water coolant, then we add at least 2 gallons of water to the radiator. After 1 hour i try to start the engine and it wouldn't start at all. The car had to be towed to the ferrari dealer and they found water inside the spark plug (they still checking for the rest of the engine) . Anybody now that if this could be a serious damage to the engine or simple drainage and gasket replacement will do the trick? I am located in Jakarta,Indonesia.
