Apparently when you disconnect the fan belt and nothing moves, noise still there
It's linked to my revs it seems. The higher I rev, the higher and louder the sound
Sound is there if car is cold and hot. Day and night. Although it's louder when I start the engine in the morning. After driving for a while, it goes softer.
No other symptoms. Could it be in the engine? There is no loud metal in metal or clanging sound. Maybe s fit knocking sound, but I might be imagining it
