Failing: Pulley or Internals?
**1.6L long nose motor**
Judging by this video, does this look / sound like a crank pulley issue or spun bearing? I've seen some play on other people's pulleys but it doesn't look as bad as some of the youtube videos I've seen. Just fielding some opinions before I drain the oil tomorrow. Noise has gradually gotten worse over a few days of driving to this point where the video was taken.

Agreed, judging solely by the video, this looks like a pulley issue. You might need to pull the timing belt off to inspect the nose of the crank, but start by just pulling the accessory belts and determining whether the pulley itself just isn't bolted down correctly.

Ouch. I'd say pulley. You probably do have bearing damage but from what I've seen, a lot of motors work "just fine" and then they get pulled apart and the bearings look like ****. Which means you're probably ok.
If you want to know the status of your bearings without ripping motor apart, drain oil, look for shiny specs, and send oil to blackstone labs for analysis hustler style. $30.

I'm going to go out on a limb and say "perhaps not."
When a shortnose engine suffers The Failure, the damage usually seems to be localized to the crank nose, the key, and the timing belt pulley. It's all just guessing at this point, but if the problem does turn out to be nothing more than a loose pulley, I'd think your best bet is to just fix it and move on. In a worst-case scenario (if there is already damage to the crankshaft beatings), it's not like you're going to make it any more broken by trying the simple fix.

Update:
Crank pulley bolt came loose with almost no torque. Everything was worn. Replaced a lot of the parts, torqued it up with copious amounts of red threadlocker and shes running fine. No metal in the oil.
There was coolant hanging out in that area, water pump must be leaking. The pulley still wobbles every so slightly, but I'll be building a block over the winter so I'm not too worried about it.
