Boiler loses pressure over a few days and it appears to be coming from on top of the heat exchanger
SOURCE: boiler keeps losing pressure when the heatings off
Hi Leehardcast,
Yes the problems are related. The system is low on water. So now instead of water you have air in radiators which is easily compressed when it heats up. Then pressure loss when it cools down.
Add some water to your system until you have 15lb pressure and bleed out upstairs radiators at the same time.
Please rate this response and Good luck, Phil

check the tops of all your radiator valves for bypass if found, easy to repair best of luck

I suggest you just buy a new one. I had the almost to exact same problem that you have. its going to be just as expensive to repair it to just getting a new one.
