Weird hissing noise around 2300RPM

[VernySanders]

Anyone notice this? Seems like a fricken snake is on the other side of your air vent, drivers side at around 2300 RPM and up? PCV system? Any ideas at all? Hardest thing to diagnose when theres no way to check at or when the vehicle is not driving... any input appreciated

Check for vacuum leaks using carb cleaner, propane etc. (read up first before catching your engine on fire) and make sure your A/C is turned off

I'll start looking. It just randomly started in the middle of the winter while on my way to work from the airport. And it's never stopped. Now it's getting annoying to the point where its agitating to drive.
