Mend Ravenheat RS81E Boiler Heating Thermostat

How can I fix my Ravenheat boiler ?

My Ravenheat boiler is occasionaly looseing pressure.
Each time the pressure drops water appears to have escaped from the auto air vent at the top of the boiler.
If I turn down the themostat on the boiler for the heating the problem does not occur.
Do I need to replace this air vent?
