INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter
 Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between (C) and (B)
exceeds the limit, replace them with new one.
 If reduction of outer diameter appears in a position other than (B),
use it as (B) point.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-143,
"CylinderBlock".
1. Using a scraper, wipe off oil, scale, gasket, sealant and carbon deposits from surface of cylinder head.
CAUTION:
Never allow gasket fragments to enter engine oil or engine coolant passages.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions (A), (B), (C), (D), (E) and
(F).
 If it exceeds the limit, replace cylinder head.
INSPECTION AFTER DISASSEMBLY
Valve Dimensions
 Check the dimensions of each valve. For the dimensions, refer to EM-139, "CylinderHead".
 If dimensions are out of the standard, replace valve and check valve seat contact. Refer to "Valve Seat Con-
tact".

 Check the valve spring pressure at specified spring height.
 If the installation load or load with valve open is out of the stan-
dard, replace valve spring.
INSPECTION AFTER INSTALLATION
Inspection for Leakage
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
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, check again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including
engine oil and engine coolant.
 Bleed air from lines and hoses of applicable 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.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

CYLINDER BLOCK
 Loosen main bearing cap bolts in the reverse order shown in
the figure in several different steps.
10. Remove main bearing beam.
11. Remove main bearing caps.
CAUTION:
Be careful not to drop main bearing, and to scratch the sur-
face.
 Using main bearing cap bolts, remove main bearing cap while
shaking it back-and-forth.
12. Remove crankshaft.
13. Remove main bearings and thrust bearings from cylinder block and main bearing caps.
CAUTION:
 Be careful not to drop main bearing, and to scratch the surface.
 Identify installation positions, and store them without mixing them up.
14. Remove oil jet. (VQ35DE)
ASSEMBLY
1. Fully air-blow engine coolant and engine oil passages in cylinder block, cylinder bore and crankcase to
remove any foreign material.
CAUTION:
Use a goggles to protect your eye.

CYLINDER BLOCK DISTORTION
 Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.
 Measure the distortion on the cylinder block upper face at some
different points in six directions (C), (D), (E), (F), (G) and (H) with a
straightedge (A) and a feeler gauge (B).
 If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
 Install main bearing caps (2) and main bearing beam without
installing main bearings, and tighten main bearing cap bolts to the
specified torque. Refer to EM-110, "
Disassembly and Assembly"
for the tightening procedure.
 Measure the inner diameter of main bearing housing with a bore
gauge.
 If out of the standard, replace cylinder block (1) and main bearing
caps as assembly.
NOTE:
Cylinder block cannot be replaced as a single part, because it is
machined together with main bearing caps.

Cylinder Bore inner Diameter
 Using a bore gauge, measure cylinder bore for wear, out-of-round
and taper at six different points on each cylinder. [(A) and (B) direc-
tions at (C), (D) and (E)] is in longitudinal direction of engine.
