I have started having a strange noise coming from the engine compartment....sounds like Ginger Baker doing a drum roll right close to passenger side windshield area, starts at about 50mph and quits about 55 or so. It started out being intermittent but is pretty regular now. Just before this started I had a check engine light warning which ended up being upstream OS sensors which I replaced with Bosch sensors. Anyone know what's going on here?

I'd greatly appreciate any suggestions or advice.

Take a video of the sound if you can.

 

I've got the video but don't know how to attach a .mov file

 

So I've narrowed this down a little. My check engine light came back on had code for bank1 upstream O2 sensor again (I recently replaced both upstream offers with Bosch) and had the code reset which made this noise not as loud, long or often. The next day check engine light was on and the noise returned in intensity and duration. Any ideas?
