These photos are taken from the front Veiw .
1st photo is the position at rest, which is full retard, oil fills the cavity as the engine starts, oil pressure over comes the clock spring, as the computer calls for less timing it releases oil pressure.
2nd photo is full advance, notice there is a indent "hash/shallow slot".
Last photo one of the cavities that can be "blocked" is pointed out.l last photo got rotated 90degrees for some reason.
