 Mating surface of rocker cover
 Mating surface of rear timing chain case
6. Tighten camshaft sensor bracket bolts in numerical order as
shown in the figure.
NOTE:
The order of tightening bolts in the same for bank 1 and bank 2.
7. Measure difference in levels between front end faces of cam-
shaft bracket (No. 1) and cylinder head.
 Measure two positions (both intake and exhaust side) for a
single bank.
 If the measured value is out of the standard, reinstall camshaft
bracket (No. 1).
8. Inspect and adjust the valve clearance. Refer to EM-17, "
Inspection and Adjustment".
9. Install in the reverse order of removal after this step.

DISASSEMBLY
1. Remove the following parts:
 Intake manifold collector: Refer to EM-28, "
Exploded View".
 Intake manifold: Refer to EM-32, "
Exploded View".
 Oil pans (lower and upper): Refer to EM-38, "
Exploded View".
 Front and rear timing chain case: Refer to EM-79, "
Exploded View".
 Cylinder head: Refer to EM-96, "
Exploded View".
2. Remove knock sensor.
CAUTION:
Carefully handle sensor avoiding shocks.
3. Remove rear oil seal retainer.
 Remove by inserting screwdriver between main bearing cap and rear oil seal retainer.
CAUTION:
If rear oil seal retainer is removed, replace it with new one.
NOTE:
Regard both rear oil seal and retainer as an assembly.
4. Remove baffle plate from main bearing beam.
5. Remove piston and connecting rod assembly with the following procedure:
 Before removing piston and connecting rod assembly, check the connecting rod side clearance. Refer to
EM-119, "
Inspection".
CAUTION:
Be careful not to drop connecting rod bearing, and to scratch the surface.
a. Position crankshaft pin corresponding to connecting rod to be removed onto the bottom dead center.
b. Remove connecting rod bearing cap.
c. Using a hammer handle or similar tool, push piston and connect-
ing rod assembly out to the cylinder head side.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod big
end.
6. Remove connecting rod bearings from connecting rod and connecting rod bearing cap.
CAUTION:
 Be careful not to drop connecting rod bearing, and to scratch the surface.
 Identify installation positions, and store them without mixing them up.
7. Remove piston rings form piston.
 Before removing piston rings, check the piston ring side clearance. Refer to EM-119, "
Inspection".

 Press-fit pilot converter with its chamfer facing crankshaft as
shown in the figure.
18. Install knock sensors.
 VQ25DE
- Install knock sensor so that connector faces the front of the
engine.
- After installing knock sensor, connect harness connector, and
lay it out to rear of engine.
CAUTION:
 Never tighten mounting bolts while holding connector.
 If any impact by dropping is applied to knock sensor,
replace it with new one.
NOTE:
 Check that there is no foreign material on the cylinder block
mating surface and the back surface of knock sensor.
 Check that knock sensor does not interfere with other parts.
 VQ35DE
- Install knock sensor so that connector faces the rear of the
engine.
- After installing knock sensor, connect harness connector, and
lay it out to rear of engine.
CAUTION:
 Never tighten mounting bolts while holding connector.
 If any impact by dropping is applied to knock sensor,
replace it with new one.
NOTE:
 Check that there is no foreign material on the cylinder block
mating surface and the back surface of knock sensor.
 Check that knock sensor does not interfere with other parts.
19. Note the following, assemble in the reverse order of disassem-
bly after this step.
Drive plate When installing drive plate to crankshaft, be sure to correctly
align crankshaft side dowel pin and drive plate side dowel pin
hole.
- If these are not aligned correctly, engine runs roughly and “MI” turns on.
