Hey guys

I started the car fine. moved it outside for a hand wash. opened the hood and the valve cover. watched the valve clearance. no more clearance at the 6th exhaust valve. it is stuck and hard. seat valve need to redone. want to drive to the shop who repairs engines but when i start the car again I have this sound which i never had before even though my valve was already without clearance. this car won't move anymore and I will bring the cylinder head without showing them the head when still in the car.

but still curious to understand what makes this whining noise. thx for any input. it sounds like a belt but at the same time it comes from the head.
