Are you certain it is motor oil? Has the transmission, cooling lines, power steering pump, lines and rack and pinion been checked? Even brake fluid can look like motor oil. I attached two pics below. The first shows common places for a rack and pinion to leak. The rubber boots at each end can fill will steering fluid and slowly seep out. Also, the PS pump in pic 2 can leak. Check the hoses as well.
If they are not finding a leak with a dye, I question if the engine is the source of the leak.
Let me know.
