Does this sound normal

Hey guys. Does this sound normal?

Can't hear much. Sound isn't very clear

Sounds Like Piston Slap at a very high rate , Could be something Different . but sounds like something is either tapping Slapping or Pinging , The sound is not very clear , but Does not sound like a (healthy) Motor
