Red face Whistling Noise

My 1991 Econoline's motor is making a whistling noise. With the engine cover off it sounds like it is coming from the rear of the motor. It doesn't do it will idling, but under throttle it is pretty loud also when you turn the ignition off you can hear it. Anyone have any ideas what ir could be?
