(21) Engine oil panEngine oil pump (19) is mounted to the bottom of the cylinder block inside the engine oil pan (21). The engine oil pump (19) pulls oil from engine oil pan (21). The engine oil pump pushes the oil through the passage to the engine oil cooler (17). Oil then flows through engine oil filter (16). The filtered oil then enters the supply for the number 4 main bearing (11), turbocharger oil supply line (10), and main oil gallery (9). The supply for the number 4 main bearing (11) supplies oil to the number four camshaft bearing.The main oil gallery (9) distributes oil to main bearings (7), piston cooling jets (4), and camshaft bearings (8). Oil from main oil gallery (9) exits the front of the block. The oil then enters a groove that is cast in the front housing.Oil enters the crankshaft through holes in the bearing surfaces (journals) for the main bearing (7). Passages connect the bearing surface (journal) for the main bearing (7) with the bearing surface (journal) for the connecting rod.Oil supplied from
