IS 350 V6-3.5L (2GR-FSE) (2006)
o. Insert a compression gauge into the spark plug hole.
p. Fully open the throttle.
q. While cranking the engine, measure the compression pressure.
HINT: Always use a fully charged battery to obtain engine speed of 250 rpm or more.
NOTICE: The measurement must be done as quickly as possible.
Standard compression pressure: 1.4 MPa (14 kgf/cm2, 199 psi) or more
Minimum pressure: 0.98 MPa (10.0 kgf/cm2, 142 psi)
r.
Perform the inspection above for each cylinder.
Difference between each cylinder: 0.1 MPa (1.0 kgf/cm2, 15 psi) or less
s. If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into the cylinder through the spark plug hole.
Then perform the first 3 steps under inspect the cylinder compression pressure for the cylinders with low compression.
HINT:
^
If adding oil helps boost the compression, it is likely that the piston rings and/or cylinder bore are worn or damaged.
^
If pressure stays low, a valve may be stuck or seated improperly, or there may be leakage in the gasket.
t.
Connect the 2 injector driver connectors as shown in the illustration.
u. Install the 6 spark plugs.
Torque: 25 Nm (254 kgf-cm, 18 ft. lbs.)
v. Install the 6 ignition coils.
Torque: 10 Nm (102 kgf-cm, 7 ft. lbs.)
w. Connect the 6 injector connectors.
x. Connect the throttle body connector.
y. Connect the 4 connectors.
