Single pipe steam radiator vent squirting water

We have a long, narrow radiator in our bedroom that has recently started to squirt water. The radiator is the last one on a 1 pipe system. It had a maid o mist #5 vent. I replaced it with the same. After 2 days it started to do the same thing. We have an oil fired Weil McLain boiler. This is the only radiator in the house that is doing this. We did have the boiler serviced this last nov. I did make sure that the valve to the radiator is all the way open. When the radiator starts to heat up there is some banging. I also put some shims under the feet to make sure it was pitching back towards the valve. Any suggestions?

    Make sure the piping in the basement has the right pitch also, you may have to shim both ends of the radiator 93/4 at air vent end and 1/2" at input end?) to raise the line under the floor.
