There is a small hole in an area of the connecting rod on top of the big end,
usually aimed about 30 to 45 degrees from the rod centerline. (axis being the
crankpin center) The oil flowing through the crank to the rod will spurt out of
the hole at certain crank positions. (when the oil hole in the crank matches up
with it) This provides adequate lubrication because the oil ring smoothes and
distributes this spurted oil. If you have too much oil reaching the walls, as
in crank splash, you can overstress your oil rings. (possibly even break them)
