Hi all. I have got an issue with my engine. Few weeks ago my coolant started boiling. I've done a co2 test and it was present in coolant- my first call was head gasket. Done the job, took both out, took them for skimming and pressure testing, put new gaskets, new thermostat, water pump, expansion tank cap (just in case it wasn't releasing the pressure correctly) and put everything together. After starting the engine everything was fine until got to the right temperature and started boiling again. When I turn the car off the large amount of coolant just shoot out from opened expansion tank- very high pressure. I've done the co2 test again...the gas is still present in coolant. Can anyone confirm what's the next thing to check? Is it cracked block or slipped liner or something totally different?
