InspectionNBS0001E
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.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range (A) shown in the figure.
3. If it is out of range, adjust it.
NOTE:
When checking oil level, insert oil level gauge (1) with its tip aligned with oil level gauge guide on cylinder
head.
ENGINE OIL APPEARANCE
Check engine oil for white turbidity or heavy contamination.
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 oil leakage around the following areas:
Oil pans (lower and upper)
Oil pan drain plug
Oil pressure sensor
Oil filter
Valve timing control cover
Mating surface between cylinder head and rocker cover
Mating surface between front timing chain case and rear timing chain case
Mating surface between rear timing chain case and cylinder head
Mating surface between rear timing chain case and cylinder block
Mating surface between rear timing chain case and oil pan (upper)
Mating surface between cylinder block and cylinder head
Mating surface between lower cylinder block and cylinder block
Crankshaft oil seals (front and rear)
Camshaft position sensor and exhaust valve timing control position sensor.

OIL PRESSURE CHECK
WARNING:
Be careful not to burn yourself, as engine oil may be hot.
Oil pressure check should be done in “Neutral position” (M/T models) or “Parking position” (A/T
models).
1. Check the engine oil level. Refer to LU-6, "
ENGINE OIL LEVEL" .
2. Remove undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and
remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure sensor.
4. Install the oil pressure gauge (SST) and hose (SST).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
kPa (kg/cm2 , psi)
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure sensor as follows:
a. Remove old liquid gasket adhering to oil presser sensor and the mating surface.
b. Apply liquid gasket and tighten oil pressure sensor to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-45, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
c. After warming up engine, make sure there is no leakage of engine oil with running engine.
