I think it's a freeze plug?

I was talking to a friend recently, and she told me that she has a number of old cars that aren't running, and that I can have any of them (except the Corvette, about which more later) that I could fix. The most recent casualty is a '91 Toyota 4Runner that she said has a cracked head. It has the 3VZE engine. This one was the easiest to get to, so I looked at it first. I wasn't too sure about her cracked head diagnosis; her description of symptoms made me think it might be a coolant leak.

I went by her house when nobody was home, and found the 4Runner unlocked. I opened the hood, filled the radiator, and squeezed the radiator hoses to try to create some water circulation since I didn't have the keys. After a little while of doing this, I found water dripping off of the driver's side exhaust manifold. I couldn't find any coolant hoses or pipes in that area, but there is a freeze plug close by. I can't see the freeze plug without some disassembly, but I also can't see any other source for the water.

As much as I would like to have this vehicle for free, she is a friend, and I also don't want to take advantage of her. She was willing to give it away in the face of an $1800 head gasket job or $3000 new engine, but a freeze plug is a completely different story. She likes this vehicle and would be happy to drive it if it can be fixed inexpensively.

Does this sound like a freeze plug to you? Or should I do more disassembly? I'm not charging her anything for my current diagnosis, but if I take things apart, I may as well fix it and charge her a few bucks. Otherwise, I can just tell her to tow it to her mechanic.
 
well if she wants to drive it and it ends up being just a freeze plug that can be replaced with a new one then change it out and give it back to her. Show up at her house and tell her you know it was just a cheap freeze plug so I feel keeping it since I know you like this vehicle.

+2. Win win situation. Freeze plug you build goodwill and still get (another) free vehicle. Not freeze plug, you know what you're getting into.

You do know that those engines are known for blowing head gaskets right? I was going to buy one until i did some research on them.
