Sooooo, head gasket or duff radiator cap?

1/ yes it does.

2/my hose pipe won't reach the garage which is 1.8 to 2.0 miles away, depending which route I take!

3/ yes, my finger can vouch for that as in the video.

4/ so am I.

Thanks for your input.

I had a similar episode with one of my cars, an Avenger sorry for swearing. Had to change the thermostat housing and after I changed it, it did the same symptoms.

It stopped bubbling up when I took the thermostat out and it holds its water with no pressurising. Run it up hot and driven it, no pressurising. I’ve not checked the old thermostat or put a new one in yet, it’s a low use car, but suspect it was just a stubborn air lock somewhere in the system or faulty thermostat.

I never thought of taking the 'stat out. I'll try that next time I go over to the lockup. I'll take a flask of boiling (almost) water, also I'll take my full size 'water' fire extinguisher with me as a stand in for a hose pipe, see if I can reverse flush some of that brown silt out!
