Your jumping too fast - firstly any Mayo in the oil filler cap or on your dipstick -if not all maybe OK?

Secondly top up the coolant ( dont overfill the tank as it will cause cooolant to evacuate the expansion tank ) give her a good 10 mile thrash at 70 - park up and leave till next morning - open expansion tank cap and if silent all well and good - no exhaust gases in the coolant system - if a clear hiss of escaping gas then that points to exhaust gas in the coolant tank and therefore likely HGF - also when you open the tank see if you can smell exhaust gas in the tank.

If all OK - i would get her on a ramp in a garage to do a coolant pressure test - has saved me twice - could be a perished hose leaking or failing water pump or maybe also am IMG failure - but i would thought you would see this when running the negine for a good time on the drive and looking closely at the plastic inlet manifold .
