I've searched all over to try to see if someone else has had the same problem. The timing belt is making a almost whistling sound from the drivers side timing belt inspection cover. The timing belt was replaced in April of 2017 so I thought it was the serpentine belt. I got a new serpentine belt and removed the old one but while it was off I started the engine just to double check the sound and sure enough it was still there. Got the stethoscope out and it wasn't making any odd bearing related noises coming from that side or anything. Really don't want to tear it apart to replace the belt but I may have to, and I know someone will ask what brand the belt I put in was and it was an Asian. Any ideas or input would be appreciated.
