: Slight engine grind sound?

09-01-09, 08:37 AM
Just noticed this today since it's the first time I HAVEN'T had the A/C or blower on - there is a very, very slight grind sound that I can hear while sitting at the wheel in park...If I rev the engine, it gets faster with the rpm's. It's extremely faint though. Any idea what this could be caused from? Again - it's VERY faint, but definatly there.
