Reaching out to y'all because I need some help pinpointing the cause of this sound. I don't have a CEL, but I get this annoying faint screech under heavy throttle especially going up a hill. Car has 80k miles and I had the timing service done about 1,500 miles ago. The noise was apparent before the timing service and hasn't changed after. I drove around without the accessory belt and I didn't hear the noise which led me to believe it was related to that. I got a new belt, alternator pulley, and greased the tensioner bearing. Unfortunately the sound is still there although maybe a bit more quiet. I will try the no belt test again for good measure, but I'm thinking it could be an exhaust manifold gasket leak. Although I don't feel a loss in performance, my noise does sound like the noise in this clip https://m.youtube.com/watch?v=1ca3vGCB3T8 except it's not as loud. Also thought about the possibility of a vacuum/ boost leak. The oil dipstick test showed the pcv was good. Could it even be my clutch? Drivetrain is pretty much stock. Any insight is greatly appreciated
