yes, goes away or sometimes gets louder, it's weird. I am at a loss at the moment. Intermittent
Wondering if its the harmonic balancer. But not sure. Big job expensive, don't want to pay money and not fix problem. Also in south california, inland empire, near Los Angeles. Don't know any mechanics i trust to work on it, and dealers say it too old . Plus they are expensive.

It's just a temporary check to see if any of those items which normally spin with the engine are making noise, as @lucky131969 mentioned. It's a perfect first step at diagnosing and should be done before "firing the parts canon".

Once upon at time I was a FEAD engineer. I knew instantly it was something in the front end and not one of the small pullies.
It could be the AC clutch or the compressor itself. I'm voting for the clutch
