1. A method for an engine, the method comprising:
selectively supplying lubricating oil to a tip of a rocker arm via oil channels aligned only during opening of a valve coupled to the tip, wherein supplying the lubricating oil includes splashing the lubricating oil via an oil supply channel to a cover of the rocker arm;
directing the splashed oil from a ridge formed into the cover that is offset from the oil supply channel to a first protrusion housed on the cover, the splashed oil further directed from the first protrusion onto the tip of the rocker arm as a first jet of oil, wherein the first protrusion is positioned directly in line with the first jet of oil and a valve lift mechanism of the valve during opening of the valve; and
directing the splashed oil from the ridge to a second protrusion housed on the cover, the splashed oil further directed from the second protrusion onto a pushrod system as a further jet of oil,
wherein the pushrod system is coupled to the rocker arm during opening of the valve,
wherein the second protrusion is positioned directly in line with the further jet of oil and the pushrod system,
wherein each of the first protrusion and the second protrusion is horizontally offset from a pivot point on a rocker shaft along a horizontal axis running through the valve lift mechanism and the pushrod system, and
wherein a first amount of oil dripped from the first protrusion onto the valve lift mechanism is higher relative to a second amount of oil dripped from the second protrusion onto the pushrod system.
