I removed *the automatic vent valve above the flow valve, also removed the
expansion tank.
Plugged the 1/8th inch outlet and used the 1/2 inch to connect a line
adding 21# of air. This kept solid for 24 hours,
after visual checks and pressure test I am 100 % confident no leaks in the
system are present
I have been hearing a slight gurgling for sometime, inside the boiler. I
am aware noises can travel, however I am certain this gurgling is from the
boiler internals.
Now here's a kicker that just happened today. Yesterday I add water to
bring up pressure to
12# *(from 7#) * it went down to 7 again as it has been, and then it
actually went back up to 10lbs...

Valves around regulating valves are closed and do not leak through..
Is it possible I somehow have air trapped in the boiler cavity that will
not vent?.
I am trying to keep from spending *$3- 4000 * for another boiler unless
absolutely necessary.

I'd suspect the feed valve is not holding as well as you think or there is
air trapped in the system. *Could be from the water giving off gas from the
chlorine or oxygen in the water.

As for spending the money for a new boiler, after 35 years, it may be
"free". *Energy tax credits, fuel savings, rebates, no interest financing
are all available. * I put in a new oil fired boiler and cut my fuel use by
38% over the 30 year old unit I had.
I put in a System 2000 fromwww.energykinetics.com*Pays for itself in
savings.- Hide quoted text -

The above is good advice. You will probably cut you gas bill in half.
You would be wise to consider renewing radiators too with biiger ones
to improve efficiency even more.
