I just finish replace the 2nd hand head, valve, rocker arm and camshaft. Then finish replace new 2 timing belt n new all oilseal. This is my 1st repair 4D68 diesel engine successes, but I dont know why the coolant water was dry slowly and boil when I running engine without radiator cap. How to repair?Head, valve, rocker arm and camshaft. Then finish replace new 2 timing belt n new all oilseal.

First, you should be using coolant, not water. It has a much higher boiling point. Next, the water has to be going some where. Have you checked the engine oil and trans fluid for it mixing?
