Abstract: An engine lubrication system is provided which has an oil pump for supplying lubricating oil from an oil pan to an area that is to be lubricated, the oil pump being positioned outside-the-oil pan and driven by a camshaft. An oil passage formation member fitted to the lower face of an engine block so as to be housed in the oil pan, comprises an oil inlet passage for taking in oil from the oil pan to the oil pump and a relief valve for discharging excess oil discharged by the oil pump via an oil supply passage.
