Oil Flow Chart

This chart describes the flow of oil through the 700 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. The oil pressure switch is fed off the main oil galley.
