    Worn bore? Piston rings? Valve guides?

    There is a hint of that on one or two. Im pretty sure bottom right and top left are 1 & 6 that are prone for the oval bores. Some of them do have the brown tinge which is what you want.

    Here were what my 1&6 looked like when it started blowing oil on the overrun.
