540i whirling noise from engine

I have replaced the ccv diaphragm...idler pulleys...the guy I bought it from had put a new power steering pump on...the water pump looks fairly new as well and there is no overheating....the noise almost sounds like it's coming from the power steering pump but I know that can be deceiving

Sorry for the quality of the video ...you can hear the noise at the beginning then the sound gets weird
