Unfortunately I didnt get to check for combustion gases in the coolant today as I woke up with a migraine and had to cancel the slot in the garage, will hopefully get a new time on Monday.
I suffer from those from time to time and it's horrible.
With my overheating issue, recently resolved, thanks to guys here, it ended up being a combination of radiator cap, thermostat, faulty clutch fan and radiator/cooling system that needed to be flushed. Now she runs 190 all day long.
