Random whining from engine
Maybe I’m being super paranoid here, but just lately I’ve noticed a whine coming directly from the top of my engine.. I’ve never managed to capture it on video until now due to how random it is
https://youtube.com/shorts/pB1Z3tLq2YM Is there anything I should be possibly checking?

OP will correct me if I'm wrong but there's a kind of buzzing sound that start around the middle of the video. strangely I can't see the timestamp with the exact time.

It happens every time I start up and idle now, noticed it last night.. it came on within about a minute of starting up and seemed to come and go every other few minutes

Dare I say it, the first time I ever noticed it was after an oil change and I had used an oil flush for the first time. Literally the second I started it back up, it could just be a total coincidence or possibly related.
