Sorry, I know very little about these engines, and I’m still learning about mine, so forgive me if this is a stupid question. I noticed when I started the truck tonight, there was quite a bit of water vapor accumulated on the curb where I parked. The pic shows the puddle, and that was idling about 5 minutes. It’s a 2001 5VZ-FE with 189k miles on the clock. Runs and drives great with no engine issues. Newer plugs, coils, and wires, and TB/WP was just done three weeks ago. Engine doesn’t hesitate and doesn’t feel sluggish.
Pay attention to other cars, v8’s, as they pull out of parking lots where they were parked several hours, like leaving work. You’ll see water running out the tailpipes.

Water vapor is actually one of the byproducts of gasoline combustion. You combine Gas + Oxygen and you get out C02 + H20. When it is cold the water vapor condenses and makes liquid water you are seeing. If you are seeing this once the engine and exhaust pipe are hot, then you might have an issue.
Yup, totally normal. All of my Yota's seem to have more vapor than other vehicles I've owned for whatever reason.

Only worry if it smells distinctly 'sweet', and your coolant levels start going down.
