The car has developed a new noise. It sounds more of a chatter than a tick. It is very slight when you are sitting in gear at stop lights. But the other day when i was backing into the garage i got to the top of the drive way and it started to really really chatter, so i stopped the car on the slope of my driveway and began to push the accelerator as if i was going to back up, and then the car really started to chatter on me, it almost sounds like a rattle as well. I dont feel anything wrong with how it shifts. or how it drives. but this noise is about to really drive me up the wall. The car just pushed 89K miles. It has new plugs and everything there is good. When i redid the valve cover gaskets i looked around at the valves and push rods and everything seemed to check out there, they all felt the exact same to me. I am desperate to get the noise gone. here is the computer link to the video
