An improved cam shaft configuration for internal combustion engines is provided wherein the oil is efficiently diverted from the camshaft cap to adjacent camshaft lobes. A reorientation of the camshaft oil diverter improves the distribution and increases the quantity of oil flow without building in additional oil passages to supply oil to cams, that would introduce additional expense without substantially alleviating existing prior art lubrication deficiency problems. The invention obviates the known prior art configurations that suffer from the drawback of insufficient distribution of lubricating oil to adjacent camshaft lobes that is effected by oil diverter configurations.
