Warning
•Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your
skin by washing with soap and water immediately after working with engine oil.
•Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the
engine oil have cooled.
1. Disconnect the negative battery cable.
2. Remove the under cover.
3. Remove the oil pressure switch.
4. Screw the SST into the oil pressure switch
installation hole.
5. Warm up the engine to normal operating
temperature.
6. Run the engine at the specified speed, and note
the gauge readings.
•If the pressure is not as specified, inspect for
the cause and repair or replace if necessary.
Oil pressure (approximate quantity) [oil
temperature: 100°C {212°F}]
147 kPa {1.5 kgf/cm

Note
•The oil pressure can vary with oil viscosity and temperature.
7. Stop the engine and wait until it is cool.
8. Remove the SST.
Caution
•Any sealant stuck at the end of the oil pressure switch can cause operation malfunction of the oil
pressure switch.
Be sure there is no sealant at the end of the oil pressure switch.
9. Apply silicone sealant to the oil pressure switch
threads as shown.
10. Install the oil pressure switch.
Tightening torque
12—17 N·m {1.2—1.8 kgf·m, 9—13 ft·lbf}
11. Install the intake manifold bracket.
12. Start the engine and inspect for oil leakage.
•If the oil leaks, specify the faulty part and
repair or replace it.

1. Position the vehicle on level ground.
2. Warm up the engine to normal operating temperature.
3. Stop the engine and wait for 5 min.
4. Verify that the oil level is between the L and F marks on the dipstick and check the engine oil condition.

Warning
•Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the
engine oil have cooled.
•A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall,
causing death or serious injury. Never work around or under a lifted vehicle if it is not securely
supported on safety stands.
•Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your
skin by washing with soap and water immediately after working with engine oil.
Caution
•In case you spill engine oil on the front pipe, wipe it off completely. If you fail to wipe the spilled
oil, it will produce fumes because of the heat.
1. Position the vehicle on level ground.
2. Remove the the oil filler cap.
3. Remove the under cover.
4. Remove the oil pan drain plug.
5. Drain the engine oil into a container.
6. Install the oil pan drain plug with a new the washer.
Tightening torque
12—17 N·m {1.2—1.8 kgf·m, 9—13 ft·lbf}
Note
•The amount of residual oil in the engine can vary with the replacement method, oil temperature, etc. Verify
the oil level after engine oil replacement.
7. Refill the engine oil with the specified type and amount, then install the oil filler cap.

Note
•Inspect all fins on each turbine wheel.
Is there any problem?Yes Replace turbocharger.
No Go to next step.
6 Is any engine oil found inside turbocharger
turbine housing?YesExcessive amount of oil is found:
Replace turbocharger.
Small amount of oil is found:
Wipe oil off of vehicle, then go to next step.
No Go to next step.
7 Is any engine oil found inside turbocharger
compressor housing?Yes Wipe oil off of vehicle, then go to next step.
No Go to next step.
8 Is any engine oil found around oil pipes attached
on turbocharger center housing?Yes If oil leaks from damaged pipe, replace oil pipe.
Then, go to next step.
No Go to next step.
9 Is any engine oil found inside air intake pipes or
hoses?Yes Wipe engine oil off.
No Turbocharger is okay.
Install all parts removed in Step 2.
Then go to next step.
10 Is engine compression correct?
(See B2–8 COMPRESSION INSPECTION)Yes Inspect oil leakage from outside of engine.
No Inspect for following:
•Damaged valve seat
•Worn valve stem and valve guide
•Worn or stuck piston ring
•Worn piston, piston ring or cylinder
Service as necessary.
11 Verify test results.
•If okay, return to diagnostic index to service any additional symptoms.
•If malfunction remains, replace PCM. (See F2–64 PCM REMOVAL/INSTALLATION)
