A system for an engine comprising an engine drive system and an oil delivery system is provided. According to one embodiment, the engine drive system includes a chain that engages a plurality of drive sprockets and a chain guide that pivots about a pin. Further, the pin may include an internal oil passage that is in fluidic communication with the oil delivery system. In this way, improved oil lubrication can be provided with simplified structure and manufacturing.
