Some Toyotas can live long enough to see hundreds of thousands of kilometers on their odometers before they finally give out. But have you ever wondered what the engine of a Toyota actually looks like after, say, half a million kilometers?

If you have, then get a load of this clip. It’s an engine-teardown video from YouTube channel speedkar99, and it features a 1NZ-FXE 1.5-liter four-cylinder engine from a 2004 Prius.

But then again, this is from a hybrid vehicle where the internal combustion engine isn’t used all the time, so you can’t expect that much wear,” he says.
