It's still not circulating properly and sending the heated coolant out the overflow. He now says that something in the circulation system was cooked by the overheating. The water pump, the thermostat, where the impeller blades connect to the pump shaft may have melted, radiator, broken impeller pieces blocking coolant channels, etc. etc.
I'm really at a loss here now.
The temperature gauge does not register overheating, but it's obviously leaking and something is wrong.
I'm trying to get back on my feet from surviving cancer, unemployed, and no more money to put into this car right now (or at all?)
At what point do I walk away or keep dumping money into it?
The engine seems to run fine and after letting it cool off for about an hour I can see that the coolant tank is only about 1/3 full (of course 3/3 full would be way too much. Point is a fair amount of coolant came back out the overflow and something is wrong.
Should I cancel the insurance, keep it garaged, and slowly save up and fix the cheapest thing first (thermostat?) or is there just going to be so much collateral damage from the meltdown that I walk away and sell it as a roller?
Another mechanic I just talked to told me to have the test done for hydrocarbons in the coolant. If there are, he said to walk away. He also said that the coolant is circulating, since the gauge is not showing abnormal readings or overheating and that it could still be more air in the system.
Please offer advice. I'm desperate.

Did he refill the system under vacuum? If not, I would not be surprise that there is air trapped in it. The line you blew off the cooler is the highest point in the system, and is there to vent air trapped in the oil cooler to the tank in the trunk; so I again would not be surprised there is air in the system if vacuum was not used to refill the system.
