yikes...white smoke now, no oil to top end

A compressoin check may or may not show a small head gasket leak to the water jacket but there is a good chance it will if you are smoking like that.....well, if your engine is smoking like that. It just may not show you anything conclusive. Does the white smoke smell like oil or like antifrezze or like nothing? It could also be a crack in a head or block that opens up when the engine heats up; which coudl explain why it ran OK for 10 minutes. Is this a rebuild?

I have no good info to add about the lack of oiling.
