Lubrication system
Engine lubrication is carried out under the pressure created by a gear oil pump driven by the crankshaft. The lubrication system includes, in addition, the oil filter and pressure reducing valve which limits the pressure of the oil.

Gear type oil pump installed in front of the timing cover. The engine SR20DE mounted oil cooler for additional cooling oil.
| Fig. 2.74. Placement of the oil pressure sensor
|
Oil pressure sensor (Fig. 2.74) is screwed into the rear plane of the cylinder on the right side of the oil filter. Oil pressure warning light comes on when the oil pressure drops below 0.2 kgf / cm2. Engine oil filter Nissan 15208-type molded N8903, installed at the rear of the engine block. Above the oil filter mounting sleeve is a bypass valve, which is triggered in the event of clogging of the oil filter. Capacity filter 0.4 liters. When changing the oil, the oil filter is replaced.
