The sound is like a small man with a hammer, ting, ting, very metalic sounding when engine is running at idle. But not all the time. I think it is an exhaust leak but I can not tell fur sure, sounds like it is coming from every were. With a steathascope(sp) I can hear it in the headers, intake and valve covers very high pitch metalic sound. not super loud and not always present more when motor cold I think.

Thanks for any input.

Exhaust leaks can sound like almost anything. Another thing to check is that the torque converter to flexplate bolts are tight.
