Default knocking sound when trying to start the car

the sound kinda sounds like a quick 2-4 knocks while the engine is turning over before the car actually run. it doesn't do this all the time, maybe 1 out of 10 cranks. i don't know if this could cause it but i do have low power steering fluid b/c i took it off when i was taking off the head and now it has air in the system and i haven't had time to bleed it yet.
