1.5L REVOTORQ ENGINE 76 D. LUBRICATION SYSTEM Lubrication System Schematic Layout Description The lubrication system layout is as shown in the schematic above. The oil pump is mounted inside the crankcase. Oil is drawn up from the sump through oil pump strainer and passes through the pump to the oil cooler and then to the filter. The filtered oil flows through the internal drilled holes into the crankshaft oil gallery from here it is supplied to connecting rod bearings and also to the main bearings by means of intersecting passages drilled in the crankshaft. It is then injected through the cooling nozzles to the underside of the piston / piston gallery for cooling. There is a separate line that goes to lubricate the turbocharger. There is another path which takes the oil up from the crankshaft oil gallery to camshafts oil gallery in cylinder head and lubricates the camshaft. The camshaft oil gallery also provides the oil needed by the HLA. The relieved oil drains back to oil sump.
