Inspection

INFOID:0000000009164368

ENGINE OIL TEMPERATURE HISTORY

Check that engine oil temperature history is not stored in ECM. (This work is recommended to be performed
by GT-R certified NISSAN dealer.)

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 5 minutes before checking.

1.

Pull out oil level gauge and wipe it clean.

2.

Insert oil level gauge and check the engine oil level is within the
range (A) shown in the figure.

3.

If it is out of range, adjust it.
• Adjust the engine oil level 10 mm below the H level within the

range A.
NOTE:
• Engine oil level check and oil refill must be performed con-

stantly [at least every 3000 km (1800 miles)].

• If the customer does not drive on following condition, it can

be filled up to H level:

- Higher-RPM (approaching redline) operation
- Frequent high pedal force braking from moderate and higher

speeds

- Frequent throttle activation
- Fast revving throughout the RPM range

• Engine oil is consumed by driving, and engine oil consumption increases under driving conditions listed

below:

- Frequent heavy load and high rpm.
- Frequent acceleration and deceleration.
- Traveling distance per driving is 10 km or less.
- Engine starting on a slope (e.g. hill).
NOTE:
When checking the engine oil level, insert oil level gauge (1)
with its tip aligned with oil level gauge guide.

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

Visually check engine assembly surrounding area for smears and leakage of engine oil.

Maximum engine oil consumption

: 0.5L (1/2 US qt, 1/2 Imp qt) / 1000km (621-3/8 mile)

LIST OF CHECKING POINTS FOR OIL LEAKAGE

Check for engine oil leakage around the following areas:
• Oil pans (lower and upper)
• Oil pan drain plug
• Oil pressure sensor
• Oil level sensor

Oil smears/leakage status from transmission assembly

Required operation

Reference

Smears

*1

Smears from each part on the engine assembly

1.

Use part cleaner or an equivalent to wipe out 
smeared oil. 

2.

Check again for oil leakage.

—

Leakage

*2

Mating surface of oil pan (upper and lower) 

1.

Remove oil pan (upper and/or lower).

2.

Remove old liquid gasket completely, and 
then install oil pan (upper and/or lower). 

3.

Check for oil leakage.

*3

Drain plug

Replace the drain plug washer, and then check 
for oil leakage.

*3

Oil filter

1.

Remove oil filter.

2.

Remove foreign materials adhering to oil fil-
ter installation surface.

3.

Install oil filter. 

4.

Check for oil leakage.

*3

Oil filter bracket

1.

Check the mounting condition of oil filter 
bracket, oil pressure sensor, oil cooler hose, 
and oil thermostat.

2.

 Remove and reinstall above parts if there is 
malfunction. 

CAUTION:

Replace the O-ring and gasket when rein-
stalling the parts. 

3.

Check for oil leakage.

*3

Oil cooler, oil cooler hose, and oil cooler pipe

1.

Specify oil leakage point.

2.

If oil leakage is from connection of parts, re-
move foreign materials from mating surface.

3.

Replace with a new gasket. 

4.

If oil leakage is from the part itself, replace 
with a new part. 

5.

Check for oil leakage.

* 3

Mating surface of flywheel housing

1.

Remove flywheel housing assembly.

2.

Remove flywheel.

3.

Remove rear oil seal, and then check the oil 
seal mounting surface and crankshaft.

4.

Replace the rear oil seal if there is not mal-
function.

5.

Check for oil leakage.

*3

Front oil seal

1.

Remove front oil seal, and then check the oil 
seal mounting surface and crankshaft.

2.

Replace the front oil seal if there is not mal-
function.

3.

Check for oil leakage.

*3

Turbocharger

1.

Specify oil leakage point.

2.

If oil leakage is from oil tube connected, re-
move foreign materials from mating surface.

3.

Replace with a new gasket. 

4.

If oil leakage is from the part itself, replace 
turbocharger only. 

5.

Check for oil leakage.

Draining

INFOID:0000000009164369

WARNING:

• Be careful not to get burned, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin

contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible. 

1.

Warm up the engine, and check for engine oil leakage from engine components. Refer to 

LU-4, "Inspec-

tion"

.

2.

Stop the engine and wait for 5 minutes.

3.

Loosen oil filler cap.

4.

Remove front undercover. Refer to 

EXT-37, "FRONT UNDER COVER : Exploded View"

.

5.

Remove drain plug (1) and then drain engine oil.

Refilling

INFOID:0000000009164370

1.

Install drain plug with new washer.

CAUTION:

Be sure to clean drain plug and install with new washer.

2.

Refill with new engine oil.
Engine oil specification and viscosity: Refer to 

MA-22, "Fluids and Lubricants"

.

CAUTION:

• When filling engine oil, never pull out oil level gauge.
• The refill capacity depends on the engine oil temperature and drain time. Use these specifica-

tions for reference only.

• Always use oil level gauge to determine the proper amount of engine oil in engine.
