Low oil pressure?

I'm trying to get some pictures together of a crank that I have and I have rods through the oil holes on # 1 & 2 and degree plates I might change to protractors to show the angles and the oiling points, right now I have found that the right bank will have to be oiled through the cap as YR said but the left bank needs to be oiled through the block were the stock oil holes are or close to them, havent got that far yet.
