Question: Why is the end of the return pipe in the UFM closed except for a small hole (1/8"?) from which we see the oil issuing at right angle to the pipe.
Theory: The small hole there to create a restriction. Without a restriction at the end of the line there would be little or no pressure in the return line. If there is no pressure in the return line would less oil find its way down to the rockers and down into the timing case? Comments?
