INSPECTION AFTER INSTALLATION
The following are procedures for checking fluids leak, lubricates 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 GI-27, "
Recommended Chemical Products and Sealants".
 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.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
 Warm up engine thoroughly to make sure there is no leakage of fuel, 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.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
 Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III
and it is directed according to inspection procedure of EC section. Refer to EC-796, "
Diagnosis Pro-
cedure".
 Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-15, "
Inspection".
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Remove intake manifold. Refer to EM-156, "
Component".
b. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to EM-176, "
Component".

4. Clean the mating area of intake valve timing control solenoid
valve. Insert a clean shop cloth (with no oil adhesion) into the oil
hole (A) of the cylinder head.
5. Install engine mounting bracket (RH), engine mounting insulator,
and torque rod (RH) under the Step 4 condition. (With intake
valve timing control solenoid valve removed, and a shop cloth
inserted into the oil hole.) Refer to EM-207, "
Component".
6. Crank engine, and then make sure that engine oil comes out
from intake valve timing control solenoid valve hole (A). End crank after checking.
 Check engine oil leakage by oil amount adhered to the waste inserted into the oil hole.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:
 Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.
 Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engine oil contamination.
 Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.
7. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid
valve oil hole of the cylinder head.
 Remove oil filter (for intake valve timing control), and then clean it. Refer to EM-186, "
Component".
 Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-11,
"Lubrication Circuit".
8. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
 Clean oil groove if necessary. Refer to LU-11, "

INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter
 Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.
 If reduction of outer diameter appears in a position other than “d2”,
use it as “d2” point.

When performing this inspection, cylinder block distortion should be also checked. Refer to EM-219, "
Inspec-
tion After Disassembly".
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for engine oil or water.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions using straightedge (A)
and feeler gauge (B).
 If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install cylinder head gasket.
2. Apply new engine oil to threads and seating surface of bolts.
CAUTION:
If cylinder head bolts re-used, check their outer diameters before installation. Follow the "Cylinder
Head Bolts Outer Diameter" measurement procedure.
3. Install cylinder head, follow the steps below to tighten cylinder
head bolts in numerical order as shown.Limit (“d1” – “d2”): 0.15 mm (0.0059 in)
