The oil pump is located inside the oil pan (26). The engine oil pump pulls oil from the engine oil pan. The engine oil pump pushes the oil through the passage to the engine oil cooler (21). Oil then flows through engine oil filter (20). The filtered oil then enters the turbocharger oil supply line (16). The filtered oil also enters the main oil gallery (14).

(1) Unit injector hydraulic pumpThe main oil gallery distributes oil to the following areas: main bearings (22) , piston cooling jets (10) and camshaft bearing (11). Oil exits from the main oil gallery in 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. Passages connect the bearing surface (journal) for the main bearing with the bearing surface (journal) for the connecting rod.The front housing passage sends the oil flow in two directions. At the upper end of the passage, oil is directed back into the block. The oil then flows up to the cylinder head gallery (8) through passage (3) to the rocker arm mechanism. A passage (19) sends oil to the oil pump idler gear bearing.Oil from the front main bearing enters a passage (17) to the camshaft idler gear bearing. Oil passages in the crankshaft send oil from all the main bearings through the connecting rods to the connecting rod bearings.Note: Engines that are equipped with an auxiliary oil filter will receive oil from a port. The filtered oil will be returned to the engine oil pan.The unit injector hydraulic pump (1) is a gear-driven axial piston pump. The unit injector hydraulic pump raises the engine oil pressure from the typical operating oil pressure to the actuation pressure that is required by the unit injectors.The oil circuit consists of a low pressure circuit and a high pressure circuit. The low pressure circuit typically operates at a pressure of 240 kPa (35 psi) to 480 kPa (70 psi). The low pressure circuit provides engine oil that has been filtered to the unit injector hydraulic pump. Also, the low pressure circuit provides engine oil that has been filtered to the lubricating system of the engine. Oil is drawn from the engine oil pan. Oil is supplied through the engine oil cooler and the engine oil filter to both the engine and the unit injector hydraulic pump.The high pressure circuit provides actuation oil to the unit injector. The high pressure circuit operates in a pressure range typically between 6 MPa (870 psi) and 25 MPa (3626 psi). This high pressure oil flows through a line into the cylinder head. The cylinder head stores the oil at actuation pressure. The oil is ready to actuate the unit injector. Oil is discharged from the unit injector under the valve cover so that no return lines are required.The oil pump bypass valve (24) limits the pressure of the oil that is coming from the engine oil pump. The engine oil pump can pump more than enough oil into the system. When there is more than enough oil, the oil pressure increases. When the oil pressure increases, the oil pump bypass valve will open. This allows the oil that is not needed to go back to the suction side of the engine oil pump .The bypass valves (12) and (13) will open when the engine is cold (starting conditions). Opening the bypass valves achieves immediate lubrication of all components. Immediate lubrication is critical. Cold oil with high viscosity causes a restriction to the oil flow through the engine oil cooler and the engine oil filter. The engine oil pump sends the cold oil through the oil cooler bypass valve. This causes the oil to bypass the engine oil cooler. The oil filter bypass also allows the oil to bypass the engine oil filter. The oil is then pumped through the turbocharger oil supply line and the main oil gallery in the cylinder block.When the oil gets warm, the pressure difference in the bypass valves decreases and the bypass valves close. After the bypass valves close, there is a normal flow of oil through the engine oil cooler and the engine oil filter.The bypass valves will also open when there is a restriction in the engine oil cooler or in the engine oil filter. This design allows the engine to be lubricated even though the engine oil cooler or the engine oil filter are restricted.The high pressure relief valve regulates high pressure in the system. When the oil pressure is at 695 kPa (100 psi) or more, the high pressure relief valve opens. When the high pressure relief valve opens, oil is returned to the suction side of the oil pump. The oil flow continues to the engine oil cooler. Coolant flows through the engine oil cooler in order to cool the oil.If the oil pressure differential across the engine oil cooler reaches 155 17 kPa (22 2 psi), the valve will open. Opening the
