This method of extracting oil from the rear of a piston ring during engine operation is based on the theory that when the top ring is sitting on the lower flank the pressure differential between the entrance to the sample hole and the atmosphere forces some of the combustion gases, along with oil from around the sample hole down the pipe in the form of a mist. 2 plugs had a tiny amount of oil on the electrodes.
