CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to
EC-665, "
Fuel Pressure Check".
a. Remove fuel pump fuse to avoid fuel injection during measure- ment.
3. Remove engine cover with power tool. Refer to EM-169, "
Component".
4. Remove ignition coil and spark plug from each cylinder. Refer to EM-187, "
Component" and EM-188,
"Component".
5. Connect engine tachometer (not required in use of CONSULT-III).
6. Install compression gauge with adapter (SST or commercial ser- vice tool) onto spark plug hole.
 Use compression gauge adapter (SST) which is required onNo. 7 and 8 cylinders.
 Use compression gauge adapter (if no SST is used) whose picking up end inserted to spark plug hole is smaller than 20
mm (0.79 in) in diameter. Otherwise, it may be caught by cylin-
der head during removal.
7. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and engine rpm. Perform these steps to check each cyl-
inder.
Compression pressure:
Unit: kPa (kg/cm2, psi)/rpm
CAUTION:
Always use a fully changed battery to obtain the specified engine speed.

 If the engine speed is out of specified range, check
battery liquid for proper gravity. Check engine speed
again with normal battery gravity.
 If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (valve, valve seat, piston, pi ston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure compression pressure again.
 If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug
hole of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check the piston rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal- functioning. Check valves for damage. Repl ace valve or valve seat accordingly.
 If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil, cylinder head gaskets are leaking. In such a case, replace cyl-
inder head gaskets.
8. After inspection is completed, install removed parts in the reverse order of removal.
9. Start engine, and make sure that engine runs smoothly.
10. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-666, "
Trouble Diagnosis Introduction".

WARNING:
 Situate vehicle on a flat and solid surface.
 Place chocks at front and back of rear wheels.
 For engines not equipped with engi ne slingers, attach proper slingers and bolts described in PARTS
CATALOG.
CAUTION:
 Always be careful to work safely, avoid forceful or uninstructed operations.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
 Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-9, "
Fluids and Lubricants".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
 Bleed air from lines and hoses of applic able lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.

Checking Fuel LineINFOID:0000000001327104
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loos
e connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001327105
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the workshop.
 Be sure to work in a well ventila ted area and furnish workshop with a CO
2 fire extinguisher.
 Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:
 Use gasoline required by the regulations for octane number. Refer to GI-5, "
Precaution for Fuel
(Unleaded Premium Gasoline Recommended)".
 Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosion-proof containe r and put the lid on securely. Keep the container in
safe area.
- Release fuel pressure from th e fuel lines. Refer to EC-87, "
Fuel Pressure Check" (VQ35DE) or EC-
665, "Fuel Pressure Check" (VK45DE).
- Disconnect negative battery terminal.
 Always replace O-ring and clamps with new ones.
 Do not kink or twist tubes when they are being installed.
 Do not tighten hose clamps excessi vely to avoid damaging hoses.
 After connecting fuel tube qu ick connectors, make sure quick
connectors are secure.
Ensure that connector and resin tube do not contact any adja-
cent parts.
 After installing tubes, make su re there is no fuel leakage at
connections in the following steps.
- Apply fuel pressure to fuel li nes with turning ignition switch
“ON” (with engine stopped). Th en check for fuel leaks at con-
nections.
- Start engine and rev it up and check for fuel leaks at connec- tions.
 Use only a genuine NISSAN fuel filler cap as a replacement. If
an incorrect fuel filler cap is used, the “MIL” may come on.
 For servicing “Evaporative Emi ssion System” parts, refer to
EC-40, "
Description" (VQ35DE) or EC-618, "Description"
(VK45DE).
 For servicing“On Board Refueling Vapor Recovery (ORVR)”
