Have you tried reving while in park?
Have you check the condition of the drive belt?
It could also be either the Idler or Tensioner Pulley. To check, with spray lube in hand and vehicle off, find the Idler and tensioner, now spray the center bolt on One of them. Start Vehicle and rev engine if noise is gone for short period then replace pulley. If noise still present repeat proccess on other pulley.
If noise still present spray belt lightly while running and rev if noise gone replace belt.
