It is not the original engine. I do not know how many miles are on this engine.
My experience (from rebuilding two engines) has been that broken compression rings resulted in blow-by and lack of compression, and that in this case (reasonable compression and little blow-by) that oil rings were somehow the cause of excessive burning of oil. I was hoping that there was a remedy short of, at least replacing the rings, short of rebore and replacing pistons as well. I don't know what is the cause of oil ring failure. Could a solvent loosen or clean what is affecting the oil ring function and thus the smoking? Probably not.
