Abstract
A system for preventing outflow of oil from an oil filler port of an overhead camshaft engine. The system comprises a partition wall extending downwardly from a cylinder head cover to divide the interior thereof into a timing chain chamber having a timing chain gear and a timing chain and a valve chamber having the oil filler port, a cam shaft and intake and exhaust valves. The partition wall prevents lubricating oil splashed in the timing chain chamber by rotation of the timing chain from getting into the valve chamber, and thereby prevents outflow of lubricating oil through the oil filler port.
