lately when i start up my evo in the morning, i hear a rattling noise. it happens when i turn the ignition. the noise only last for a second or two. i notice that when i hear the noise and let go of the clutch quickly, it stops rattling. it sounds like im griding ice. thats the only time i hear the noise tho. i never hear it when im driving or turning off the car. i also dont notice any power losses. any suggestions?

Thanks.
