Sorry for such a delay. The noise is starting to get worse I would say.
I really don't think it is the heat shield. It is so much more heavy sounding than a small heat shield. My best guess was the engine torque mount. I have a VF mount, checked It, and it happend the rubber bushings were shot, so I thought that was definitely it. Ordered a new vVF mount and it is still there. And actually I believe it made the noise last longer and I hear it every time the car is cold.
It sounds like it is coming from right below the shifter, but a little more towards the engine. When the car is cold I need to get going and then when the car hits about 3k the noise will appear. Then it fades away as the rpms fall. After 2k it is gone. I can be stopped and rev the engine to make the noise appear as well. Then once the car is warmed it is gone.
Could it be the T-stat?
Thanks for all the help
