Is the knocking noise sort of a tapping sound that fluctuates with the engine revs? For at least a year now my car often starts making tappity noises when it's warmed up and idling. The sound seems to originate from the cambelt area.(my belt, tensioners, etc were replaced approx 2yrs/32k miles ago) It goes away after blipping the throttle a few times, as far as I understand it may be sticking valve lifters.
Be cautious when running the engine without the auxiliary belt as the water pump is driven by it.
