I have been ignoring a light screeching sound that is made when my wheel was turned and held to the right. But now, even when im driving or still, there is this constant, metallic-sounding ring from the engine, unless the wheel is turned to the left. It is driving me crazy and I don't want to cause any potential damage to the car by ignoring this. When I stop the car, leave it running, and pop the hood it is heard best. Any ideas on what this is? Thank you
