The sound disappears when the engine warms up. Any ideas what it could be?? Thank you Video Link: https://youtu.be/W2dJZ_Dlvag
Most likely broken manifold studs. Common problem with the hemi.

Thanks for the reply. Unfortunately it's a 4.7l. are breaking manifold bolts also an issue with these motors as well?
