Desperately need help identifying this sound...

[vfuentes80]

History: Right hand tensioner cracked, stopped car immediately after hearing the tapping, took apart, due to time constraints It took roughly 30 days to replace, tried to fire car up, nothing... No fuel, track issue down to passenger fuel pump, replace, she fires up. I hear the sound in the video for the first time, I take everything apart again, inspect tensioner and chains where they belong, put it back together, start it same sound, I need help tracking this one down... Any suggestions on what's making the noise???

Water pump, remove the belt and start the car if the sound goes away.
