Engine Oil: Testing and Inspection

ENGINE OIL

Inspection


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 check that the engine oil level is within the range (A) shown in the figure.
3.If it is out of range, adjust it.

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 engine oil leakage around the following area.
- Oil cooler
- Oil temperature sensor
- Oil pan bolt
- Oil pan (upper and lower)
- Oil pan drain plug
- Oil pressure sensor
- Oil filter
- Valve timing control cover
- Valve timing control solenoid valve (intake and exhaust)
- Front cover
- Turbocharger
- Turbocharger oil tube (feed and return)
- Turbocharger oil hose
- Mating surface between high pressure fuel pump and camshaft bracket
- Mating surface between cylinder head and camshaft bracket
- Mating surface between cylinder block and cylinder head
- Mating surface between camshaft bracket and rocker cover
- Crankshaft oil seals (front and rear)

OIL PRESSURE CHECK


WARNING:
- Be careful not to get burned, as engine oil may be hot.
- When checking engine oil pressure, shift position should be "Parking" (CVT models) or "Neutral"
(M/T models), and apply parking brake securely.
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).

2 : Starter motor
White arrow indicates : Engine front


CAUTION:
Never drop or shock oil pressure sensor.





3.Install oil pressure gauge [SST: ST-25051001 (J-25695-1)] (A) and hose [SST: ST-25052000 (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: [1][2]Engine Oil Pressure.

If difference is extreme, check oil passage and oil pump for oil leakage.

6.After the inspections, install oil pressure sensor as follows:
a.Remove old liquid gasket adhering to oil pressure sensor and engine.
b.Apply liquid gasket and tighten oil pressure sensor to specification.
Use Genuine RTV Silicon Sealant or equivalent.

Tightening torque: Exploded View.

c.Check engine oil level.
d.After warming up engine, check that there is no leakage of engine oil with running engine.
