Why would PO have tapped a bolt into the oil pan. This is a few inches above the drain plug which is perfectly fine? The tapped bolt appears as it's leaking as well.

Re: Why is there a second bolt tapped into oil pan?
Low oil sensors were used on other GM V8 applications, but can't remember seeing one in a thirdgen. Seems that the threads in those pans used a more substantial boss than just tapping the pan.
Doesn't really matter what it was for, it's not doing anything now. I'd be damn tempted to wait til the next oil change, and while it's drained, I'd clean the snot out of the area, clean, clean, clean it again. Get it as clean as possible, find a plug that will fit right, even if that means going up a size, or using a self tapping drain plug, and then use an auto-rated liquid thread sealant, and run the plug in snug.
This is one case where I'd probably consider cleaning the area as clean as possible, and seal the area with regular JBWeld. Not the JBKwik or whatever they want to call it, but the 24hr set variety. It's not a structural joint, the goal is to end the seepage. It'd be a lot faster than changing the pan, and doesn't cost much. Worst case you might still have to change the pan later.

That's my plan just to clean it and seal it up, it's actually barely leaking but want it sealed all the way. I was just curious as I had never seen these level sensors before.
