In reading Tracy's book on rotary rebuild he mentions dropping a 3/16" dowel into the front cover oil passage leading to the pump drive after removing the oil injection pump drive.  I talked with Bruce who stated this is not nessessary.  Last I talked with Tracy this morning, he was ankle deep in coolant so I'm not bothering him anymore today:-).  Question, what is the reasoning behind this dowel and is it required?
