So I went and readjusted the belt just to make sure nothing funky was going on. I get a solid and repeatable 64.9-65Hz cold adjustment. After running the car about a 10 mile loop the Gates app reads a consistent 79.9Hz. The belt still sits slightly off of the crank pulley. Furthermore I noticed some grease weeping out of the top idler pulley. The second image is a video of the noises. Maybe everything is copacetic and I'm freaking out for nothing?
