I know this is hard as **** to diagnose without hearing the sound. But I got my stethoscope out and poked around and It is not the valve lash, and its not any belts. It sounds like an exhaust leak kinda, but I cant find where the hell its coming from. I am just wondering if any of you have come across this before.

 

you can have a friend drive it and listen to see where it might be comin from to get an idea where to look.
