Overheating
Ok I have seen alot of issues on this but not completly like mine so I need to know what you all may think.First of it a 1987 toyota 4runner has 281 thousand miles on it im the 2nd owner and engine was rebuilt at 140 thousand miles or so,i just replaced the thermostat about 2 weeks ago with in that 2 weeks i was getting heat here and their was thinking had a bad heater core I was driving the vehicle noticed it was getting very hot so I got to my house and let it sit not thinking about checking the water I left for a friends house about 4 hours later got about 5 miles down the freeway and it was red again pulled over car died,Had some water brought to me waited till vehicle cooled down put it in at that point vehicle wouldn't restart but would turn over but would smell something of a gas smell,tried to jump it that didn't work also noticed water flowing out of underneith the vehicle,so the next morning I go to get it towed and tried to start it again and some large amount of water was coming out of the exhaust.Thinking headgasket but really not to sure why it will not start.Please help.Have pictures if that help but to big to post.

if coolant was coming out the exhaust then thats a pretty clear sign of a BHG. I'm assuming its got the 3.0L, those are notorious for head gasket problems. Another clear indicator of a BHG is your temp guage spiking every now and then as hot exhaust gas passes by a coolant temp sensor. Good luck.

BHG = Blown Head Gasket. If you have the slimy milkshake-looking goo on the underside of your oil fill cap,, can be pretty sure you have coolant mixing in the oil.
Might drain your oil and see if you get both water and oil.

I would consider a little condenstion on the valve cover to be normal, unless you have coolant spraying everywhere in the engine compartment. I dont know if a blown head gasket would case a no start, maybe if it was on multiple cylinders.

When you overheat the engine you almost guarantee a warped head that will result in a blown head gasket at best, and a cracked head or block at worst. Especially if it gets so hot the engine shuts down like that.
A compression test will at least give you an idea of what's going on in there.
Btw, what engine are we talking about here?
