Might help as I have air in the system despite bleeding the furthest rad and pump. Think it's playing havoc with my boiler and the auto air vent ain't helping. I still hear trickling water from the boiler. Just realised the bloody thing sometimes stops and cycles, hopefully due to air lock.
What make valves are on now? Sometimes they make a noise due to not being balanced properly.

Is it an open vented or sealed system?
