Oil Flow Chart

This chart describes the flow of oil through the 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.
