Soo ive been getting this whine/buzz sound coming from my engine. It doesnt do it right when you start it up but if you drive it for a minute then is will start. Also if you turn the car off then turn it back on it quits until you drive it again. It almost sounds like a loud fuel pump. And im pretty sure its coming from the front of the engine somewhere. Engine runs great though, no problems. Has anybody had this problem or knows what it is? Thanks
Here's a video of it

You're talking about the whine/buzz sound that remains the same pitch even when revving, right?

 

When you rev it the tone lowers a little, but you cant really hear it when you rev it up past like 2k or so

 

Not sure, but one of these two threads might prove to be helpful:

OP fixed by changing oil:

Dealership fixed with new fuel pump and dampener:

Sounds more like the first one that was fixed by changing the oil. Ill try changing my oil asap and see if anything changes.
Thanks for your help!!
