N20 Timing Chain Whine? VIDEO

Hey guys, I'm looking for a F30 and I think I found a suitable one, however the video linked below seems to indicate a whining noise that aligns with worn oil pump gear components. 82k on the car.

Is this serious or normal? Should I pass?

Thats deff a worn out timing chain gears, I can tell from the whine, If no warranty on the car I would deff pass, if it brakes and no warranty its $3500 minimum to fix it

Thats what I figured. I checked out one in person today for comparison and it didn't have the whining. Here is a post for more information and some more videos of whining chaing.

I'll keep looking for one with CPO warranty or at least one that doesn't whine. Really sucks the engine has this achilles heel, even if its a somewhat uncommon failure.
