NOISE IDENTIFICATION !!!
S14 SR20DET

So while looking for a boost leak under the hood i had discovered another problem, when i rev the motor, you would hear a noise comming from the valve cover, like the front (Sounds kinda like a duck noise) Pass certain rpms it would go away.

To my concern it could be anything but with the help of the zilvia community, maybe someone has dealt with this problem or may have more knowledge about it. I have done my research and its still like a guessing game to me and not a straight foward answer. Its hard to identify the issue just from the noise. so if any of you might know what it is, could be simple could be not, more brains would help me get my motor healthy again thanks !

Heres a video clip i recorded of it !

It's a rapid rattle most likely coming from the VTC gear. Unplug the solenoid and rev the motor again. If it is no longer heard, you need to replace your VTC gear at some point. It can and will rattle louder and longer as it ages.
