Good call, I am indeed obsessing
A supervisor at work told me it takes about 3 months to get over it (as he took for his factory new M3). But, better safe than sorry, and that ticking from the blower vent is driving me up the wall.
I'll try an oil change in a bit, but it got new oil at the 44k service with the prev owner and it's at 47k now so...maybe wait on that a little. Thanks for the input Jim.
