    Recently did a bit of work on my new to me Prius. New plugs, coils ,EGR+cooler, intake manifold, and pcv.
    Used a borescope to peak at the pistons.
    I'm not a mechanic, so anyone have opinions on the condition of my engine?

    Sorry for the potato quality. Cylinder 2 and 3 were closest to TDC. Past that, no clue on which is which.
    :)

    Looks like you're burning some oil on 2 of them while the top 2 seem almost too clean like they getting washed with coolant.
