Jay;
        This problem drove me crazy on our 85. It turned out to be a
clogged radiator. When coolant turns to steam it acts like an internal
head gasket leak and blows coolant into the overflow. Take it to you
friendly local mechanic with an exhaust analyzer and have him "sniff" the
overflow tank with his wand for hydrocarbons. The test was done for free
for me.
