What in gods name is this noise..
 

Just this morning after starting up my car I had a weird noise.

Year: 1995 isuzu rodeo 3.2 liter, automatic, 4x4
milage: 285k

The noise:
-Its coming from the passenger-side of the car
-Its idle dependent, does not increase with road movement except rpm
-Oil level/fluid levels are all fine
-Possibly sounds like clicking, or two things rubbing?
-Not super loud put noticeable inside the car when fans and radio are off.

Issues:
-Nothing other then the noise
-The temp gauge is fine
-Oil pressure gauge is fine
-Charge gauge is fine
-No check engine light on


Any help, questions or advice would be awesome

Thanks,

Erik
