I had to get a new used motor… so I bought one with 45k on it. I had all new belts, pullies tencheners, a/c, pcv Valve, intake was cleaned.
When I start the car it idles fine no noise, once it warms up it get this high pitch noise. It’s not a belt, doesn’t fluctuate and when you give it any gas the noise goes away. Here is a link to the sound.
I have found others that have posted the same video but they never posted what fixed the issue
