Add a can of SQUICK , follow the directions & clean the glass. that should get you by. it is about time you thought about replacing your boiler & wet returns. you are about twenty years behind schedule. treat yourself. go Burnham.

    surging water level

    I have a one pipe steam system. Furnace is at least 65 years old, converted from coal to oil. I have owned the house for 6 years and the system has worked very well the whole time. A month ago I couldn't get the furnace going and my oil man told me the low water sensor, the Watts valve, was shot, and he replaced it. Since then the water level is so erratic that the furnace cuts out from low water every few minutes or more, but only for a second. I can see the water level bouncing up and down about 2-3 inches in the glass. There is a lot of brown sludge in the system, which I try to drain off every couple of weeks when I check and top up the water level. The glass is only functional for a few days before the gunky water coats the inside. I typically clean it out every time I want to check the water level. I say all this because I am not sure that the erratic water level was not present before the new low-water shutoff was installed. The water level may have been bouncing around before, but I never noticed it in the glass. My oil man hasn't been able to suggest a remedy...

    Are you skimming off the top or just draining off the bottom?
