Dave, 

I forgot to mention, the reason you might not be finding oil in the hose is
that most of it gets blown right past the hose into the carb and it might
take a little while to accumulate, I was also curious on the groups idea of
whether or not bad rings could contribute to it blowing by the valve
guides/seals?
