Just make sure you check it regularly until you rebuild it. Keep it topped off to full mark and at least you know it has a good oil with good additives in it.
Good luck on the future rebuild
The best advice I have read on this post. You must have some idea how many miles/ quart. Just because it smokes some is no reason to tear down an engine.
