If you increase the rpm just a little, it stops. When it goes back to idle, the squeal comes back. When you shut the engine off, the squeal continues until the engine stops turning. If when it's idling the squeal isn't there, you can put the emergency brake on, put it in gear and slowly let out on the clutch and the squeal gets worse. I've tried locating the squeal with a stethoscope but haven't been able to. It kind of sounds like the front of the alternator. The alternator is only a couple months old. If you use a rubber hose as a stethoscope, it seems loudest around the oil filler cap. It idles smoothly, so I don't think it is a vacuum leak.
