Help, i've recently rebuilt my 1990 V6, 3VZ-E, 4-Runner engine and it loses about 1 gallon of coolant a month. The engine runs excellent and doesn't show any signs of external leakage. It doesn't ever overheat either. I've put about 10,000 miles on the rebuilt engine and it still runs and performs excellent. Any suggestions?
