Best Answer

The areas that need to be lubricated are the moving parts: the connecting rod to wrist pin surface and the rings where they rub against the cylinder wall. Both get oil from the crankshaft through a very roundabout way. Oil is forced into grooves in the crankshaft main bearings through holes in the bearing shells. Holes in the crankshaft align with those grooves and deliver the oil through passages in the crankshaft to adjacent rod journals. As the crankshaft rotates those holes periodically line up with holes in the rod bearings and in turn with holes in the connecting rods. The connecting rods have internal passages that carry the oil to the wrist pins, where the oil is distributed to the oil control rings and is used by the wrist pins.
