Opinions on engine noise?
Here is the scenario.
2007 350z, 71,xxx miles
When the car is in idle the engine noise is normal, nothing out of the ordinary.
When the car is revved up past 2K RPM, from the front of the engine you can hear a scratching/ slight knocking noise (as if the chain is loose inside and is hitting the inner wall of the cover). The higher the RPM the louder the noise.
Has anyone else ever experienced this?
Can anyone give any input on what might be causing this noise?
Thanks in advance!

Does having the AC on make any difference? Sometimes the clutch on the compressor will make a little noise when it's not engaged.
Could also be the idler pulley, if it has one.
