SO, it just dawned on me how to get the oil out of the spark plug holes...I fly r/c airplanes and helicopters and have an electric 12volt fuel pump on my flight box to pump fuel in/out of the aircraft. The one I currently use is at least 5 years old and due for replacement, so I figured, why not use that to get the oil out, then clean the pump out and set it aside for future car repair
They are about $14 new, then you just need the fuel tubing...silicone, neoprene, or the yellow gas tubing from any hobby store should work just fine.
