How can i fix my central heating system?

can anyone help I have a fully pumped ch system which has started to play up i.e. after running for several minutes the vent pipe starts banging and crashing and i have to shut the system down. I have bleed everything several times and it doesnt seem to make a difference also it doesnt matter whether i run the pump on one, two or three. There is an air seperator above the cylinder could it be blocked? Any ideas appreciated. Thanks

Many thanks. Pump running fine. Emptied system and lots of sludge in f&e tank, refilled, started system. After half an hour slight banging and crashing from vent or/and feedpipe. Is this normal? Expansion tank full of warm murky water. What do I do now?
Cold water feedpipe from expansion tank to feed above air seperator is red hot. Can anyone please help? Thanks.

are you sure the circ. pump is working. I do not mean motor going round but working. isolate pump and take out the 4 alan screws see if pump head is attached to motor.

If this is ok then you have an air lock somewhere in the system
