Went for a ride with the wifey and was met with this noise on the way back...


Normal cruise. I can't believe that every time I decide just to drive normal around town either someone tries to kill me or something breaks.

Can anyone identify what's about to go down? harmonic dampener looks wobbly. The sound is intensified by the phone camera mic.

 

Sounds like an ancillary bearing.
You might wanna loosen the accessory belts one at a time to eliminate suspects.

 

It looks like you have quite a bit of crank pulley movement as well. early 1.6 are known for this, but it can happen to any of them. Make sure to check that as well as the other belts tensions.

 

Thanks guys, local miata expert was able to guide me to this:

3 bolts sheared off. 1 on it's last leg.
