Terry- When you reassemble the oil pump, be sure to pack the pump with
petroleum jelly(Vaseline)- this prelubricates it, and gives it a bit of a
suction to prime up with. Found this trick in a few factory manuals for
other cars. The petroleum jelly will break down and mix with the oil, so you
won't have to worry about it after it does its trick. I use it with every
engine I build any more.
