Help - Water leaking from Automatic Air vent on boiler

I drained it, replaced a couple of old radiators and re-filled it.

Reasons why steam boilers flood, and where to look for solutions

The boiler's water line is surging. Dirty water, a too-high pH, overfiring and improper near-boiler piping can all cause the boiler's water line to surge up and down. If there's an automatic water feeder on the boiler, it will open and close each time the water line rocks. Before long, you'll have a flooded boiler.
