2002 Corolla using massive oil

Could it be leaking into your transmission or engine coolant? If our engine coolant is milky you have found your leak.

I'd like to try replacing the PCV valve but cant even find the darn thing.

Autozone used to have diagrams of where everything is, but don't appear to anymore.

I removed the plastic cover on top and still don't see anything that looks like a PCV valve.

There are only two possible places for the oil to go, it is leaking or it is burning. If leaking, you need repairs. If burning, you need repairs. You are not going to fix this yourself, no matter what advice we are able to give you, so bite the bullet and take your car somewhere where they know how to help you.

You could keep driving it until it locks up, but my advice is that you keep your Auto Club membership up to date, and don't go out at night.

Take off the plastic VVT-I shroud. On the passenger side is a valve screwed into the head with a hose clamped to it. This is PCV valve.

I think I found it, it's actually on the drivers side.
