ABSTRACT:
Gutter forming ribs are arranged on the valley walls of a V-type internal combustion engine to intercept excess lubricant passing downwardly to the oil sump and direct it first to the individual valve actuating cams of the camshaft for lubricating the cams and second to the lower portions of the piston skirts extending below their respective cylinders at the bottom of their travel to lubricate the piston skirt and cylinder walls.
