    My cat is brand new.. about 3 months ago I got it. And I hear the noise with the hood up on passengers side somewhere towards the back of the valve cover but on the lower part of engine. It's drove perfectly fine. I parked it for a couple months bit I made sure to start it once a week.. battery died I got it jumped took it for a drive to charge battery and that's when it started happening.
