So I just recently hit 36,000 miles on my 2018 ecoboost mustang (the end of my warranty) I'm at about 36,600 now. And conveniently after my warranty ended I have a strange squeaking noise that happens when the blowoff valve opens. If I let off throttle and it opens I hear no squealing but it happens when I downshift and occasionally on medium acceleration. I change my oil WAY more frequently than the car suggests (about every 5k) and I always let the car warm up before I drive and cool down before I shut it off. There's no material on the dip stick or in the filter which leads me to believe it's possibly not the turbo. Just curious if anyone else has encountered this or any advice on how to diagnose it because it won't make the noise while the car isn't moving so I can't listen around for the noise while looking at the car. Thanks for any help
