My E46 started with a misfire then loss of power, uneven idle, white smoke and later it flooded the cylinder 4 with fuel, (disabling the spark plug) and allowing raw fuel to flow into the exhaust system and i thought it was the injectors but after changing them (i even changed the ignition coils) but there was no change, what could the problem be?

white smoke is an indication of burning coolant from a blown head gasket. have it checked to confirm
