I have a 95 Dodge Caravan 125,000 miles. To make a long story short, Coolant is running out the exhaust when it is running, even with out the system being pressurized (no cap on). Am I looking at just possible head gasket replacement or possibly worse? I can do my own work, just not sure exactly what is wrong. Any help would be appreciated.

You either have a cracked head or more likely a blown head gasket. In either case the head (s) have to come off anyway to find the cause. Are you getting combustion gases in the coolant as well?
