Tighten up the centre bleed valve, do you have a radiator key?

no I did it with a spanner/pair of pliers and when the water is turned on it still streams out. How tight does the center bleed need to be?
Tight enough to stop water coming out of it. 
The centre piece has a pointy end that goes into a hole. If the 2 are milled correctly the point, when tightened, fills the hole. There is no other seal.
The thread has a channel along the thread to let air out when loosened.
It is feasible that there's a problem with the milling of one of the parts.
