What is a ring and valve job?

It is a repair for a worn out and smoky engine. Valves are cleaned and replaced if necessary including seats and seals, the cylinders are honed and new piston rings are installed to return the engine to a clean running state. If it's to that point I would put in new bearings as well and call it a rebuild, it's a waste in my mind to rebuild the top end when it is worn out and ignore the bottom.
