Pulley Wobble
Dear MT.net,
I took the Miata out to check over some stuff, and noticed some significant pulley wobble. Running MS2, never had a chance to warm up.
Timing belt change about ~2k miles ago. Let me know what to do to assuage my panic here - or if I should be going "Oh god, new engine or rebuild time."

91.5 big nose 1.6.
I made sure to tighten the crankshaft bolt down to 120ftlbs ~2k miles ago. Key and crank checked out ~2k ago. I can recheck, but it baffles me that that could happen in ~2k.

Stop driving immediately until you tear it apart. Sucks, but better safe than sorry. Give me a few days and I can ship you my FM tool to hold the crank. Ninja tool too if you want it.
My long nose backed out once and it damaged the key way enough that I needed to change the crank. I let it go for far too long though.
Edit: and I thought 120 was on the low end of the spec.

116-122 ftlbs is what I have listed for torque.

Final update:
Tightened it down, no more wobble.
---- this fancy-*** blue loctite 242 or w/e ----. I'm redloctiting this bitch like I do my RX7s, it's never coming lose short of a torch.

Thanks for the help guys! It is appreciated!
On a troubling note, in the time I ran it while cleaned of loctite, it loosened - likely 80 ftlb range. Red loctite +130ftlb better hold that bitch in this time.
