what do these symptoms sound like?

I really like this girl and we started talking about cars and she told asked me if i could go look at her car to see whats wrong it. i went and looked.. its a 86 toyota camry lol.. i started it up and all the dash lights were stuck on for 1.. i let the car run for 15 minutes and everything seemed fine other thanthe lights and black smoke out the back. she told me she hasnt driven it since it "blew up on her"
so ill i have so far is.
1. Overheating
2. water in the oil
3.black smoke
4. oil shooting out the dipstick hole

maybe a head gasket? she said some mexican mechanic looked at it and said her head was cracked.. but i wasnt sure.. i listed for leaks and looks for cracks and didnt really see anything.. but then again oil was everywhere!
