Yea...going to need a lot more info.

1) is it a thin metal type of sound?
2) recently hit anything (pothole, road debris, so on)?
3) is it an internal (engine) sound?
4) old vehicle. How many miles?

It sound like metal on metal, like valve rockers, on startup when real warm out or real cold. 2007 3.8 4wd synthetic blend oil 122k goes away after about 15 seconds. Do not
