• From the oil pump, oil is directed to the oil cooler and then to the oil filter.
• The main oil passage in the rear of the engine block feeds the right, left and the camshaft galleries.
• Right oil gallery feeds the:
– rocker arm oiling manifold for the right cylinder head.
– cam followers and hydraulic lifters on the right side.
– piston cooling jets on the right side.
– crankshaft main bearings,
• a separate oil passage for each main bearing.
• also used to lubricate the connecting rod bearings.
– turbocharger.
• Left oil gallery feeds the:
– rocker arm oiling manifold for the left cylinder head.
• An oil passage connected to the gallery going up to the left cylinder head also provides engine oil to the:
– vacuum pump.
– meshed gears of the crankshaft, camshaft and high pressure fuel pump.
– cam followers and hydraulic lifters on the left side.
– piston cooling jets on the left side.
• Camshaft oil gallery feeds the camshaft bearings.
