Engine noise/whistle
 

Hey everyone,
I posted about this issue about a year ago or so but I still have not gotten it resolved so I'm hoping someone has some more information I can look into. I have a 2008 civic lx and I have been having this high pitch whistle (not quite a grind but almost) for about 2 years now. As far as I know it isn't affecting the driving but I know it is definitely not normal. My initial thoughts were the belt squealing but I was told the original belts don't usually have that issue. Someone last time told me PCV valve but I replaced that with no luck. It is important to know that this noise only occurs when idle or in the process of stopping and goes away as soon as I accelerate. I have tried tons of times to hear the noise while looking under the hood but of course it never makes the noise when I am completely stopped or parked. It also occurs mostly when the AC is on. I did record the noise but I have no clue how to upload a voice memo to this post. If any more information is needed I'll be happy to supply that. Thank you in advance for anyone who can give some suggestions on this.
