i have an l200 animal, i started getting the same symptoms, bubbling noises, over heating, water being discharged into the header tank, i had a good look around the engine,there was no oil in the water or water in the oil ( signs of head gasket failure) when the radiator cap was off and i revved hard nothing happened, no dip in water levels and no splashing out. i took the water pump off and the impellor had sheered off the shaft. fitted a new pump and its been fine, maybe all these cracked cylinder heads and warped heads are to do with the engine being run with the fault not being cured.
