What is tuktuk noise? Prominent when car's cold
Around 0:22 I rev up the Vitz/Yaris engine, the sound also follows engine revving up.
Then I let it idle and it's prominent again at 0:35. Please listen: https://streamable.com/z54arx It's more audible when the car's cold. As you rev up at idle, sound frequency also increases. The sound either disappears or the intensity reduces a lot when the car's driven and is warm enough. Becomes a bit difficult to hear then. What could be it? I've driven around 1500-2000 KM after it started coming up... been okay, haven't noticed issues in drive/power. |

That sounds like a piston broken skirt or connecting rod...top/bottom I don't know. But start looking for new motor...
