Is this normal? (noise around 5k)

[eagle talon guy]

Okay, so recently I noticed that my car (93 talon tsi) makes a weird noise at about 5k. I'm not sure what could have caused it (if it isn't normal)..
I did recently get a new BOV which was uncirculated for a little bit, and I figured maybe after I recirculate it, it would go away. It is now recirculated and it's still there..

So I guess what I am wondering is, is this noise around 4.5k normal, or is there something wrong?

In this video it's very noticeable in 2nd and 3rd gear.

Thanks.
