Very difficult to diagnose a "tapping noise" with no additional info. Are you able to post a video with sound ??? There are so many possibilities for "taps" or "knocks" in an engine that it takes sound, speed, location, and experience to even begin, and each component makes a different noise under normal or failing conditions.

Any clue as to where, what frequency (engine speed or half engine speed), under what conditions the noise occurs ? Did you remove the engine (beauty) cover and snoop for location while the engine is idling ?
