I'm just back from the dealership (2nd visit) and need to go back for a third (scheduled for Monday). They're stumped as to where the oil is coming from. They do admit oil is still coming from somewhere. They're going to dye the oil and use a black light to determine the source of the leak (sort of like an angiogram with contrast). They say there's a remote chance the mating surface of the block was improperly milled, in which case there'll be an engine swap. Kind af a grim introduction to the world of CTD.
