Baffling

[madbovineuk]

i have a toyota hi lux surf ssrx and it over heats ( not unusual for this model ) but here's the baffling part. No water or white gunk in the oil, runs without over heating on the flat but hit a hill and bang over heats and no water in the radiator in the last 3 days i have put in at least 25ltrs of water, no crack (visable on engine block ) or water lines, have flushed the radiator and fitted new thermostate all hoses are fine any help would be most appreciated

The head cracks between the valves and lets water in, you wont get water in the oil or white crap.
