I just bought a 92 Civic 1.5L with 193,000 miles. It runs great when the coolant level is full. However, after driving for about 30-40 miles, it loses enough coolant to cause the engine to overheat. There is very slight evidence of white smoke exhaust, although it almost undetectable. When I start it, there is the smell of coolant that comes through the vents. I've replaced the thermostat, ECT sensor that goes to the fan, upper and lower radiator hoses, and the radiator is new. Does this indicate that I have a small crack somewhere in the cylinder head? I've always thought that a malfunction in the cylinder head would render an engine almost useless and since the engine is strong (when not overheating), I assumed the problem was somewhere else. If it is the cylinder head, which is the best route to take in purchasing a new head: brand new or remanufactured? Thanks. Paul
