    Oil boiler leaking

    My oil burner is leaking out of what I believe is a blow off valve for safety. I've read it could be a couple of things including a full expansion tank or feeder valve. I've included a pic of my pressure which is over 30 psi if that helps, and a pic of the valve it's leaking from.
    any ideas?
    thanks guys

      I read that also, and a way to check is to shut off the burner and let the temp and air pressure go down, if it rises again with the water off its the fill valve, if it doesn't it's probably the coil. I just shut it down and will try this out.
      Is it difficult to change the coil? I'm hoping it's something simpler
      thanks for the reply

                Tap your expansion tank around the exterior up and down, does it sound like its full and filled with water?

                  It doesnt, sounds empty. Doesn't have a heavy feel either since it's mounted horizontal and has a little bounce to it. I still need to check the pressure though, maybe it lost air?
                  thank you for the useful reply

                    Because if you are close to him, he will help you out in person, like the 100's before you, who also asked for help, and got it.

                      If it sounds empty, then it’s probably not it. Turn on a zone or otherwise force the furnace to turn on and heat water. It should fill up a little bit, but not completely fill up with water. The bladder side of the expansion tank has a Schrader type valve, but I would not mess with it unless you are 100% sure there’s a problem with the bladder.

                        Fun fact, FastPhil once apologized to me that he was on vacation and couldn't come and crawl around dirt floored crawlspaces to fix 8 or 9 broken heating pipes at 10 pm on some cold horrible friday night.

                          Phil needs a bat signal.

                          Edit:
                          Or maybe we all need a phil signal.

                            If you happen to be lucky then its a matter of undoing the bolts and cutting the two copper lines to get the old unit out and simply sliding the new one in and reconnecting. Or you could be really lucky like me and have all but one of the bolts shear off so you spend the day drilling and tapping the burner
