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.
