Core plugs started to leak and the Uno's head gasget blew, propably as a result of coolant leakage. I suggest using insulated tubing to transfer heat and a pump in the system makes controlling and transferring heat quicker.


Did you mainly have issues since you effectively increased coolant system volume without providing adequate expansion volume? I have recently been reading about this on CAT engines. They mention the coolant volume vs. air expansion space needed to provide shutoff after boil protection. I am actively working on my thermal storage setup that is Dewar based and want to make sure I learn from your mistakes.
