An improved lubricating system for an internal combustion engine having a horizontally disposed cylinder. The engine is provided with overhead valves that are disposed vertically above each other and which reciprocate about horizontally extending axes. The exhaust valve lies above the intake valve and the lubricating system delivers lubricant first to the exhaust valve and then by gravity to the intake valve. In addition, an arrangement is provided for submerging the valve operating tappets in lubricant to effect lubrication and silencing.
