Dana, the Dowel referred to is to replace the drive shaft of the oil
metering pump.  I simply left mine installed.  Its true its gear is turning
while the engine is running - but I've had no problem with it.  Why not just
pull it - well there is an oil boss which feeds oil to the boss in which the
shaft rotates.  With out the shaft you might get a lot of oil flow in that
area.  I don't believe it would hurt anything but does represent oil that is
really serving no purpose flowing there.  If I did not have the shaft there
I would probably put a dowel - however make certain it is captured such that
it can not slip out of the oil pump drive shaft hole else a dowel amongst
your oil drive chain would probably not be good {:>).

That is my understanding on the topic.
