Fainted "Clanking" Sound? :(
Hey everyone, I'm starting to get a slight weird clanking noise. Can't really pinpoint it directly but it seems to coming close to the IC area/intake manifold. Its faint but if listened carefully, you can hear it. Has anyone experienced this before? Hopefully its not a heavy mechanical issue or a serious problem. I have done all major tune-ups, such as Timing belt, spark plugs, all fluids. The only things that I know I haven't replaced are the pulley belt and alternator belt. Any advice what it may be is appreciated. Thanks.
Note: I can hear the noise at idle only as far as I can tell. Its very very faint and even with the hood open its still a very fainted sound.
