ABSTRACT:
In certain motor vehicles having six cylinder internal combustion engines, the excessive use of lubricating oil after the vehicle has been driven 50,000 miles is stopped by inserting a drive rivet into the radial oil passageway in the intake valve rocker arms; such passageway connecting with an internal lubricating oil groove in the rocker arm.
