Adding water every week!

erol

I have an oil-fired steam system about 15 years old boiler - Peerless Boiler. I keep adding water every week to the boiler. The service came twice, and they checked the boiler but could not find any issues. No visible cracks and no leaks from the radiators. We also checked the barometric damper for steam when the boiler is running. No sign of steam. We filled the boiler with water and no leaks. The defective steam radiator vent can cause that much water loss or is there any other place that I need to check?

If you wouldn't mind, kindly refer to a similar problem I just posted here:

In cold weather, a defective vent can certainly lose a gallon of water in a week. What brand of vents do you have? Some close rather slowly and lose more steam than others too.
