Hey folks, I'm hoping you all might be able to help me pinpoint the source of a noise my '07 gt is making at idle.
The noise it makes is sort of a light knocking/tapping sound.
-It doesn't happen right away from a cold start - it takes a minute or two before it becomes audible.
-On warm starts it doesn't happen right away either but it comes back much quicker than a cold start.
-I've taken a stethoscope to it and hear it best towards the firewall side of the driver's valve cover though that's not the only place I could hear it with the scope.
-Noise is consistent and hasn't gotten any louder or quieter since I've taken it out this year.
-Pressing the clutch pedal doesn't seem to make a change in the noise
-Noise happens at idle and follows the speed of the engine until about 1100rpm and then if the noise is really difficult to either hear or it goes away.
-Definitely seems louder from under the car
I replaced a bunch of timing stuff and rollers/adjusters this winter and the noise persisted. The car got a new "clutch kit" installed by a local shop about 5k miles ago. I mention this because a buddy of mine had a good listen to it and took it for a drive and said he once had an automatic tranny make a similar noise and maybe it was the flywheel, other than that... I'm quite baffled.
Here's some sound clips:

(In the car - please excuse the rock tumblers noise they're quite loud)

It otherwise runs really good.
Thanks all!
