oil dipstick NISSAN ALMERA N16 2003 Electronic Repair Manual

Trouble Diagnosis of Turbocharger=NJEM0104S0206Preliminary check:
Check that the engine oil level is between MIN and MAX of the
dipstick. (When the engine oil amount is more than MAX, the
oil flows into the inlet duct through the blow-by gas passage,
and the turbocharger is misjudged failure.)
Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.

After checking both turbine and compressor,
inspect rotor shaft end play.There is resistance when the rotor shaft
is rotated by your fingertips.
The rotor shaft sometimes does not
rotate by your fingertips.
There is too much play in the bearing.

Changing Engine OilNJLC0035WARNING:
Be careful not to burn yourself, as the engine oil is hot.
Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil specification and viscosity (Except for Europe):
API grade SE, SF, SG, SH or SJ
ILSAC grade GF-I & GF-II
Oil specification and viscosity (For Europe):
API grade SG, SH or SJ
ILSAC grade GF-I & GF-II
Refer to MA-19, “RECOMMENDED FLUIDS AND LUBRI-
CANTS”.
Refill oil capacity (Approximate):
Unit:(Imp qt)
With oil filter change 2.7 (2-3/8)
Without oil filter change 2.5 (2-1/4)
Dry engine (engine overhaul) 3.1 (2-3/4)
CAUTION:
Be sure to clean drain plug and install with new washer.
Drain plug:
: 29 - 39 N·m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
The refill capacity changes depending on the oil tempera-
ture and drain time, use these values as a reference and
be certain to check with the dipstick when changing the
oil.

Dry engine (engine overhaul) 6.3 (5-1/2)
CAUTION:
Be sure to clean drain plug and install with new washer.
Drain plug:
: 29 - 39 N·m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
The refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
5. Check oil level.
6. Start engine and check area around drain plug and oil filter for
oil leakage.
7. Run engine for a few minutes, then turn it off. After several
minutes, check oil level.
