I didn't hear it well, but turbos make a screeching noise when they go south. Is oil dripping out the bottom of the turbo? If the bearing goes, it usually takes out the seal.
kay_ray Thanks this. -
No oil dripping . No oil pressure or power loss. .does the bad engine belt make that noise too ?
-
Could be a bearing noise from alternator or idle pulley also.
Connect Bluetooth to radio you can hear the sound better.kay_ray Thanks this. -
