Default Crank Pulley Came Loose

Hey everyone,

Bought a used 40th back in September and last night I noticed some minor belt squeak. Popped the hood and noticed the crank pulley wobbling like hell. Put it on a lift and re-torqued. We think the previous owner installed a lightweight pulley and didn't torque correctly. I still need to confirm it is an aftermarket pulley.

So here are my concerns... How would it last for 7 months with a loose pulley? Shouldn't I be worried about what caused it to back out (harmonic vibrations, cracked pulley, etc.)? What should I look for to confirm the engine isn't done for?
