Grinding, " diesel " noise under valve covers

No Sir, I haven't tightened the LCA or Struts yet. I did a drive way Alignment. But need a level spot to set ride height. Alignment place is about a mile, Lil less.. I did shut her off, and let her heat soak a Lil. Temp didn't raise tho..
It's really not gonna heat soak without some prolonged stop and go.
