I'll add a few things that I haven't seen mentioned yet.
First thing is your compression readings do not indicate a problem with rings. The only reason I could see for oil consumption coming past the rings would be if the gaps were all lined up. Since it ran for years previously without excessive oil consumption, that would rule out problems with the rings.
