    Does anyone know what this sound is? It does it all the time warm or cold.

    Sounds like a g2 Prius to me. What are you concerned with the sewing machine sound of the valve train?
    That’s normal the car uses solid lifters very very noisey top end. Use 10-30 weight oil thAt will help a little,
    I run a 40 weight high performance oil that really helps make that sound less clakity.

    Car must be new to you.
