Oil Flow Chart

This chart describes the flow of oil through the 800 EFI engine. Beginning in the crankcase sump, the oil is drawn through an oil
galley to the feed side of the oil pump. The oil is then pumped through the oil filter. If the oil filter is obstructed, a bypass valve
contained in the filter allows oil to bypass the filter element. At this point, the oil is supplied to the main oil galley through a crankcase
passage. Oil is then diverted three ways from the main oil galley, with the first path entering the camshaft bores, onto the rear balance
shaft journal and then draining back into the crankcase sump. The second oil path from the main oil galley feeds the lifter bores and
then drains back to the crankcase sump. The third oil path flows through a crankcase galley to the MAG side crankshaft journal and
also to the front balance shaft journal and onto the crankcase sump.
