I started hearing this sort of whistle sound today on acceleration. I don’t think it’s coming from the belt or i could be wrong. Has anyone experienced this in past? I have also uploaded a video.

Sounds like it could be either the belt, or a gasket. (throttle body or the intake manifold). Those will make a really loud, high pitch whistle like wind in a storm. i

If your comfortable, take off the belt and spin all your component pulleys (AC, Alternator, etc) with the engine off of course and see if anything is tough to spin or seized up.

I asked my mate to rev and i went through engine bay to hear the noise, I found out it’s the harmonic balancer pulley that is causing the noise, i sprayed wd40 on the pulley and it went away for a while. I was wondering how the pulley could be faulty? Im pretty sure it’s not the belt as I installed that gatorback quiet belt a few months ago.

I don't think that pulley would be faulty, there isn't much to break. If your worried, you can use any of the K20 pulleys and they will work. K24 will work as well, but they are larger so you'd need a different belt. Only the dealer will have that part though, you can't get it (that i've seen) at local auto parts store.

Belts are pretty cheap, pick up another one and give it a shot. Does the belt you have, have 1 too many ribs or something possibly?

Good luck!

Yea those Gatorback belt with different ribs design than a regular belt, it wasn’t cheap as i had to buy it from US, i think it was around $90AUD.

That area around the pulley, timing chain cover looks wet too, like it’s sweating oil, not from timing chain cover seals but on the area where pulley is on. Maybe the seal is bad and the oil coming out of that seal like sweat is making pulley to wobble.
