If the engine isn't overheating until the loss of coolant is excessive, 
have done all the checks to rule out leaking exhaust gases pressurizing 
the system, etc., I would take a long, hard look at the water pump.  I 
once had a similar problem, and it turned out that the seal was worn in 
such a way that it would not leak coolant, but, would suck outside air 
in.  At first, it was very perplexing, but, once the pump was replaced, 
the problem disappeared.



Cheers.
