Thanks Trol3.0... good pick up! So, if the cap's integrity is OK and the bottle doesn't have a leak, then the most probable cause is a leaking head gasket, versus a cracked head, yeah?

I will fill the bottle again, and check it over the next couple of weeks to see what results are created... Thanks again...
