'96 Ultra 680, same bottom for most part as the xcr800s found in later models.

anybody ever seen little hairline cracks like this from the clutch side?
wondering what the chances are that they are just surface level and dont go all the way through creating a seal leak.
was gonna swap this in my chassis as the top end looks great.

i found 2 motors on ebay with the same crack. one says "seal is out" other says cracked block crank twisted.
i guess ill use the top end on my current motor.
