I have always worried about the efficiency of modern oils to the point that I always put in straight 30 weight to break in all engines that I build, diesel or gas, for the first 200 or 300 miles. Maybe I'm just superstitious, but my engines don't burn oil. Synthetic would be my last choice for a brand new engine, anyway. I'd take it out and run something else for several hundred miles to see if the smoke didn't go away some.

New engines almost always smoke a little for a while.

I would be concerned about the statement that the PO "fixed the problem ring." It's never one ring, unless it's a broken ring. But when rings get to the point they are breaking, or if the engine is consuming oil and it can't be traced to a single cylinder for sure, replace all of them, and rescore the cylinder. On a 2.1 I could see you getting away with not reboring or replacing cylinders, they don't wear much unless something goes wrong.
