Post the vid on youtube, but my first guess would be a throwout bearing if you have a manual trans.

So noise is coming from upper manifold only heard when idling and after car warms up

Do you have an aftermarket throttle body? Is it more of a whistling sound?

Vacuum leak ? Are you sure it's not the belt ? Hole in the smog pump hose ? What's your setup

It sounded like a whistling noise. If that's a BBK TB, that's where it's from.
