I would call that lifter tick, therefore sending a knock signal to the knock sensor. "knock" can never be phantom, the ecu is hearing something. Just dismissing it as 'I know that is lifter tick, or an axle tapping on the block, or etc.." without fixing it, will cause you to melt your shit someday when it actually is knocking and you dismissed it as 'phantom'.
Noise is different, just because it is audible, doesn't mean the knock sensor picks it up, just fyi.
