What is that noise at 3200 RPM
Can anyone tell me what this metallic/tinny vibration sound is? It only happens right around 3200 rpms. Sounds like it's coming from under the hood. Kinda sounds like a thin piece of metal is being sheared off. It happens in all gears and only when the engine is warm. It never goes away as long as you hold 3200 rpms. Thanks for any advice.
