You could ask a local garage to hook their probe up in the exhaust, that'll tell you whether coolant is is in the combustion chamber. I did it years ago but in reverse because I thought combustion gases were getting into the coolant circuit. I used a swimming pool PH test kit to test the vapours in the reservoir.

I am pretty sure it's not a blown headgasket now, white smoke has gone and its been replaced by a puff of black smoke when revving it.
I've had it running with a few revs thrown in with the leak combustion tester attached and the liquids stayed blue. It's been idling/running for over an hour now.
I have found this today, no idea where this has come from as I had zero leaks in the past.
It only seems to leak when I play about with the heater and put it on hot/Hi.

I've got a mobile mechanic coming later to give it a once over.
