My car has started making this metallic grinding noise whenever it's revved to about 2500rpm. It makes the noise whether it's in gear driving along, or in neutral/declutched with me revving the engine. If I rev higher or lower, the sound goes away.
Any thoughts? The oil level was well below the minimum, but I topped that up and it's still making the noise.
