Scheme 19

1. Before starting the engine make sure the vehicle is parked on a flat and level surface, then check the oil level. If the engine is already running, turn it off and allow 10 minutes before checking.
2. Check that the oil level is within the low (L) and high (H) range as indicated on the dipstick.
3. If the engine oil level is out of range, add oil as necessary. Refer to «FLUIDS AND LUBRICANTS»(ref-233319-S02902366472006052500000) .

OIL APPEARANCE

1. Check the engine oil for a white milky appearance or excessive contamination.
2. If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken parts.

OIL LEAKAGE

Check for oil leakage around the following areas

1. Oil pan
2. Oil pan drain plug
3. Oil pressure sensor
4. Oil filter
5. Oil cooler
6. Intake valve timing control cover
7. Intake valve timing control solenoid valve
8. Front cover
9. Mating surface between cylinder block and cylinder head
10. Mating surface between cylinder head and rocker cover
11. Crankshaft oil seal (front and rear)

OIL PRESSURE CHECK

Scheme 20

Scheme 21

1. Check the engine oil level. Refer to «OIL LEVEL»(ref-233255-S29260392382006052500000) .
2. Remove engine front undercover using power tool.
3. Disconnect the oil pressure sensor harness connector.
4. Remove the oil pressure sensor.
5. Install Tools. Tool number: ST25051001 (J-25695-1) : ST25052000 (J-25695-2)
6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load. Engine oil pressure [Engine oil temperature at 80°C (175°F)] ENGINE OIL PRESSURE REFERENCE Unit: kPa (kg/cm 2 , psi) Engine Speed Approximate Discharge Pressure Idle speed More than 98 (1.0, 14) 2,000 rpm More than 294 (3.0, 43) CAUTION: If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. After the inspections, install oil pressure sensor as follows: Remove old liquid gasket adhering to oil pressure sensor and engine. Apply liquid gasket and tighten oil pressure sensor to the specification. Use Genuine RTV Silicone Sealant or equivalent. Refer to «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-233237-S23907478682006052500000) . Oil pressure sensor torque: 14.7 N.m (1.5 kg-m, 11 ft-lb) After warming up engine, make sure there is no leakage of engine oil with engine running.

CHANGING ENGINE OIL

Scheme 22

Scheme 23

1. Remove engine front undercover using power tool.
2. Warm up engine, and check for oil leakage from engine components. Refer to «OIL LEAKAGE»(ref-233255-S30690603022006052500000) .
3. Stop engine and wait for 10 minutes.
4. Loosen oil filler cap, then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer. CAUTION: Be sure to clean drain plug and install with new washer. Oil pan drain plug: 34.3 N.m (3.5 kg-m, 25 ft-lb)
7. Refill with new engine oil. Refer to «FLUIDS AND LUBRICANTS»(ref-233319-S02902366472006052500000) . Engine oil capacity (Approximate): CAUTION: The refill capacity depends on the engine oil temperature and drain time. Use these specifications for reference only. Always use the oil level gauge to determine when the proper amount of engine oil is in the engine.
8. Warm up engine and check area around drain plug and oil filter for oil leakage.
9. Stop engine and wait for 10 minutes.
10. Check engine oil level. Refer to «OIL LEVEL»(ref-233255-S29260392382006052500000) .

Scheme 24

1. Remove the engine front undercover using power tool.
2. Remove the oil filter using Tool. Tool number: KV10115801 (J-38956) CAUTION: The oil filter is provided with a relief valve. Use Genuine NISSAN oil filter or equivalent. Be careful not to get burned when the engine and engine oil are hot. When removing, prepare a shop cloth to absorb any engine oil leakage or spillage. Do not allow engine oil to adhere to the drive belts. Completely wipe off any engine oil that adheres to the engine and the vehicle.

Scheme 25

Scheme 26

1. Remove foreign materials adhering to the oil filter installation surface.
2. Apply engine oil to the oil seal circumference of the new oil filter.
3. Screw the oil filter manually until it touches the installation surface, then tighten it by 2/3 turn. Or tighten to specification. Oil filter: 17.7 N.m (1.8 kg-m, 13 ft-lb)
4. Inspect the engine for oil leakage. Refer to «INSPECTION AFTER INSTALLATION»(ref-233255-S40989892152006052500000) .
5. Install the engine front undercover using power tool.

Oil Cooler

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

Relief Valve

Inspect relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove the valve by prying it out using a suitable tool. Install a new valve in place by tapping it.

Regulator Valve Clearance

Check regulator valve to oil pump cover clearance using the following formula.

1. (Clearance) = D 1 (Valve hole diameter) - D 2 (Outer Diameter of valve) Regulator valve to oil pump cover: 0.040 - 0.097 mm (0.0016 - 0.0038 in)
