Engine Lubrication System: Other Nissan Juke I facelift

DISCONNECTING FUEL PIPING

1. Before starting work, check no fire or spark producing items are in the work area.
2. Release fuel pressure before disconnecting and disassembly.
3. After disconnecting pipes, plug openings to stop fuel leakage.

ENGINE OIL LEVEL

Note. Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop it and allow 10 minutes before checking.

Scheme 20

1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and check that the engine oil level is within the range (A) shown in the figure below.
3. If it is out of range, adjust it.

ENGINE OIL APPEARANCE

1. Check engine oil for white turbidity or heavy contamination.
2. If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.

ENGINE OIL LEAKAGE

Check for engine oil leakage around the following area.

1. Oil cooler
2. Oil temperature sensor
3. Oil pan bolt
4. Oil pan (upper and lower)
5. Oil pan drain plug
6. Oil pressure sensor
7. Oil filter
8. Valve timing control cover
9. Valve timing control solenoid valve (intake and exhaust)
10. Front cover
11. Turbocharger
12. Turbocharger oil tube (feed and return)
13. Turbocharger oil hose
14. Mating surface between high pressure fuel pump and camshaft bracket
15. Mating surface between cylinder head and camshaft bracket
16. Mating surface between cylinder block and cylinder head
17. Mating surface between camshaft bracket and rocker cover
18. Crankshaft oil seals (front and rear)

OIL PRESSURE CHECK

Scheme 21

Scheme 22

1. Check engine oil level.
2. Disconnect harness connector at oil pressure sensor (1), and remove oil pressure sensor using a deep socket (commercial service tool). CAUTION: Never drop or shock oil pressure sensor.
3. Install oil pressure gauge [SST: ST25051001 (J-25695-1)] (A) and hose [SST: ST25052000 (J-25695-2)] (B).
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load. NOTE: When engine oil temperature is low, engine oil pressure becomes high. Engine oil pressure: Refer to " «ENGINE OIL PRESSURE»(ref-621389-S06802740802014061000000) ". If difference is extreme, check oil passage and oil pump for oil leakage.
6. After the inspections, install oil pressure sensor as follows: Remove old liquid gasket on oil pressure sensor and engine. Apply liquid gasket and tighten oil pressure sensor to specification. Use Genuine RTV Silicon Sealant or equivalent. Tightening torque: Refer to " «EXPLODED VIEW»(ref-621377-S27364497322014061000000) ". Check engine oil level. After warming up engine, check that there is no leakage of engine oil with running engine.

Oil Cooler

Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary, replace oil cooler assembly.
