An oiling system for providing oil to a timing chain adjacent a cylinder head of an engine is provided. The oiling system includes a redirect feature, a vent window defined by the cylinder head, a rail feature, and a transfer feature. The redirect feature is configured to channel oil toward the vent window, the rail feature is configured to channel oil from the vent window to the transfer feature, and the transfer feature is configured to transfer oil to the timing chain. The oil is transferred from the transfer feature to the timing chain at substantially ambient pressure. The engine may be characterized by the absence of a nozzle configured to transfer oil onto the timing chain. Furthermore, the redirect feature, the rail feature, and the transfer feature may all be formed as integral, one-piece structures with the cylinder head.
