(1) Oil supply line (2) Oil return line (3) Oil cooler (4) Oil manifold (5) Oil filter (6) Oil panThe lubrication system has the following components:
Oil pan
Oil pump
Oil cooler
Oil filter
Turbocharger oil lines
Oil passages for the cylinder blockOil Flow Through The Oil Filter And Oil Cooler

Oil flow when the engine is warm. (1) Oil manifold (2) Oil supply line (3) Oil return line (4) Oil filter (5) Bypass valve for the oil filter (6) Oil pan (7) Oil pump (8) Bypass valve for the oil cooler (9) Suction lines (10) Oil coolerWhen the engine is warm, oil comes from oil pan (6) through suction lines (9) to oil pump (7). The oil pump sends hot oil to oil cooler (10). The oil is then sent to oil filter (4). Oil from the oil filter is sent to oil manifold (1) in the cylinder block and to oil supply line (2) for the turbocharger. Oil from the turbocharger goes back through oil return line (3) to the oil pan.

Oil flow when the engine is cold. (1) Oil manifold (2) Oil supply line (3) Oil return line (4) Oil filter (5) Bypass valve for the oil filter (6) Oil pan (7) Oil pump (8) Bypass valve for the oil cooler (9) Suction lines (10) Oil coolerWhen the engine is cold, oil comes from oil pan (6) through suction lines (9) to oil pump (7). When the oil is cold, an oil pressure difference in the bypass valves also causes the bypass valves to open. These bypass valves then provide immediate lubrication to all of the engine components when cold oil with high viscosity causes a restriction to the oil flow through oil cooler (10) and oil filter (4). The oil pump then sends the cold oil through bypass valve (8) for the oil cooler and through bypass valve (5) for the oil filter. The oil then goes to oil manifold (1) in the cylinder block and to supply line (2) for the turbocharger. Oil from the turbocharger goes back through oil return line (3) to the oil pan.When the oil is hot, an oil pressure difference in the bypass valves also causes the bypass valves to close. There is normal oil flow through the oil cooler and the oil filter.The bypass valves will also open when there is a restriction in the oil cooler or the oil filter. This prevents a restricted oil filter or a restricted oil cooler from stopping the lubrication of the engine.Oil Flow In The Engine

Engine oil flow schematic (1) Rocker arm shaft (2) Oil passage to the adjustable idler gear (3) Camshaft bearing journals (4) Oil passage to the air compressor (5) Oil passage to the fixed idler stub shaft (6) Piston cooling jets (7) Oil passage to cluster idler gear (8) Oil passage to the rear crankshaft seal (9) Oil manifold (10) Crankshaft main bearings (11) Oil passage from filterThe oil from oil manifold (9) is sent under pressure through drilled passages to crankshaft main bearings (10). The oil flows through drilled holes in the crankshaft. This oil lubricates the connecting rod bearings. A small amount of oil is sent through piston cooling jets (6). The piston cooling jets cool the pistons.Oil flows through passages in the timing gear housing and the accessory drive gear. This oil flows to the air compressor through oil passage (4) .Oil passage (2) provides oil to the adjustable idler gear. Oil passage (5) provides oil to the fixed idler gear. Oil passage (7) provides oil to the cluster gear. The oil flows through a passage in the shafts of the gears. This lubrication helps to ensure a long life for the front gear group.Oil passage (8) provides lubrication to the rear crankshaft seal. This ensures a long service life for the rear crankshaft seal. Oil flows into the cylinder head via a hollow locating dowel in the top deck of the cylinder block. Oil travels to camshaft bearing journals (3) and the three center rocker arm shaft supports through drilled passages in the cylinder head. The supports supply oil to each rocker shaft. Oil flows to the bushings of the electronic unit injector rocker arm through holes in rocker arm shaft (1). This same oil lubricates the valve and the rollers. Oil flows through drilled passages in the rocker arms. This oil lubricates the roller, the valve bridge and the contact surfaces of the actuator of the unit injector. Splash oil lubrication is used to lubricate other components of the valve system.When all the components are lubricated the excess oil returns to the engine oil pan.
