Check the radiator if its clogged and also try bleeding the system could be airlock-if okay have it block and pressure tested to find out more what's going on.

Hey Raz, sounds like he is pumping combustion gases into the cooling system from a cracked aluminum cylinder head or bad head gasket, most likely cracked head, call around and find a shop that does chemical head gasket tests, simple test to tell if there are combustion gases in coolant, it will save alot of time and money(unecesary parts) trying to figure it out.
