Lubrication System Schematic (1) Oil supply to the governor (2) Oil supply to the rocker arms (3) Cylinder head gallery (4) Piston cooling jets (5) Oil supply to side covers (6) Camshaft bearing (7) Passage in carrier housing (4 cylinder engines) (8) Main oil gallery (9) Oil supply to the rear support for the balancer unit (4 cylinder engines) (10) Passage in front housing (11) Main bearings (12) Oil supply to camshaft idler gear bearing (13) Oil supply to turbocharger (14) Oil supply to oil pump idler gear bearing (6 cylinder engines) (14) Oil supply to the bearings for the oil pump idler gear and the balancer shaft (4 cylinder engines) (15) Oil filter bypass valve (16) Passage (17) Oil cooler bypass valve (18) Engine oil filter (19) Engine oil cooler (20) Engine oil pan (21) Oil pump bypass valve (22) Engine oil pumpEngine oil pump (22) is mounted to the bottom of the cylinder block inside the engine oil pan (20). The engine oil pump pulls oil from engine oil pan. The engine oil is then pushed through passage (16) to the engine oil cooler (19). Oil then flows through engine oil filter (18). The filtered oil then enters the turbocharger oil supply line (13) and main oil gallery (8).

Right Side View Of Engine (13) Turbocharger oil supply line (15) Oil filter bypass valve (17) Oil cooler bypass valve (18) Engine oil filter (19) Oil cooler (23) Turbocharger oil return tubeThe main oil gallery (8) distributes oil to main bearings (11), piston cooling jets (4), and camshaft bearing (6). Oil from the main oil gallery exits the front of the block. The oil then enters passage (10) that is cast in the front housing.The front housing passage sends the oil flow in two directions. At the upper end of the passage (10), oil is directed back into the block and up to cylinder head gallery (3). At the lower end of the passage (10), oil enters passage (14). This passage will send oil to the oil pump idler gear bearing on the 4 cylinder engine and the 6 cylinder engines, and to the bearing for the front bearing for the balancer shaft on the 4 cylinder engine.Oil from the main oil gallery is forced through passages to the crankshaft main bearings. Oil enters the holes in the bearing surfaces (journals) for the main bearing (11). Oil from the front main bearing enters passage (12) in order to lubricate the camshaft idler gear bearing. Oil passages in the crankshaft send oil from all the main bearings (11) through the connecting rods to the connecting rod bearings. Passages connect the bearing surface (journal) for the main bearing with the bearing surface (journal) for the connecting rod. On the 4 cylinder engine, some of the oil that goes to the rear main bearing is directed out of the rear face of the cylinder block to passage (7) in the crankshaft seal carrier. Oil is then directed into
