Did you make sure the rings weren't lined up with each other?

[Chopperdad]

Oil Leaking down the valve guides probably.

I think that it would be the valve guide seals too.

Wow,,,and where is this coming from?

The bore may be suspect. Check for glazing of the walls, or even just plain old wear allowing too much piston to cylinder clearance, thus decreasing ring tension and allowing excess oil to not be properly removed from the wall. Also look for nicks in the oil rings.
