CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-79, "
FUEL PRESSURE RELEASE" .
3. Disconnect fuel pump fuse to avoid fuel injection during mea-
surement.
4. Remove engine cover with power tool. Refer to EM-17, "
INTAKE MANIFOLD COLLECTOR" .
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-31, "
IGNITION COIL" and EM-32,
"SPARK PLUG (IRIDIUM-TIPPED TYPE)" .
6. Connect engine tachometer (not required in use of CONSULT-III).
7. Install compression tester (Commercial service tool) with
adapter onto spark plug hole.
Use the adapter 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 cylinder head during removal.
8. 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 specified engine speed.

ENGINE ASSEMBLY
Revision: 2006 November2007 350Z
3. Remove rear engine mounting member bolts.
4. Remove front suspension member mounting nuts. Refer to FSU-5, "
FRONT SUSPENSION ASSEMBLY" .
5. Carefully lower jack, or raise lift to remove the engine, transmission and front suspension member assem-
bly. When performing work, observe the following caution:
CAUTION:
Confirm there is no interference with the vehicle.
Make sure that all connection points have been disconnected.
Keep in mind the center of the vehicle gravity changes. If necessary, use jack(s) to support the
vehicle at rear jacking point(s) to prevent it from falling it off the lift.
Separation Work
1. Install engine slingers into front of cylinder head (right bank) and
rear of cylinder head (left bank).
To protect rocker cover against damage caused by tilting of
engine slinger, insert spacer between cylinder head and
engine rear lower slinger, in direction shown in the figure.
NOTE:
Spacer is a component part of engine rear upper slinger
assembly.
2. Remove power steering oil pump from engine side. Refer to PS-28, "
POWER STEERING OIL PUMP" .
3. Remove engine mounting insulators (RH and LH) under side nut.
4. Lift with hoist and separate engine and transmission assembly from front suspension member.
CAUTION:
Before and during this lifting, always make sure that any harnesses are left connected.
Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
5. Remove alternator. Refer to SC-20, "
CHARGING SYSTEM" .
6. Remove A/C compressor. Refer to ATC-125, "
Removal and Installation of Compressor" .
7. Remove starter motor. Refer to SC-8, "
STARTING SYSTEM" .
8. Separate engine from transmission. Refer to MT-18, "
TRANSMISSION ASSEMBLY" (M/T models) or AT-
242, "TRANSMISSION ASSEMBLY" (A/T models).
9. Remove engine mounting insulators (RH and LH) and brackets (RH and LH) from engine.
10. Remove rear engine mounting member and engine mounting insulator (rear) from transmission.
INSTALLATION
Note the following, and install in the reverse order of removal.
Do not allow engine mounting insulator to be damage and careful no engine oil gets on it.
For a location with a positioning pin, insert it securely into hole of mating part.
For a part with a specified installation orientation, refer to component figure in EM-101, "Removal and
Installation" . Slinger bolts:
: 28.0 N·m (2.9 kg-m, 21 ft-lb)
