CAMSHAFT JOURNAL OIL CLEARANCE
 (Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)
 If it exceeds the limit, replace either or both camshaft and cylinder head.
NOTE:
Camshaft brackets cannot be replaced as single parts, because they are machined together with cylinder
head. Replace whole cylinder head assembly.
Camshaft End Play
1. Install camshaft in cylinder head. Refer to EM-59, "Removal and Installation".
2. Install a dial indicator (A) in thrust direction on front end of cam-
shaft. Measure the camshaft end play on the dial indicator when
camshaft is moved forward/backward (in direction to axis).
 Measure the following parts if out of the standard.
- Dimension “A” for cylinder head No. 1 journal bearing
- Dimension “B” for camshaft thrust
 Follow the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.Standard: Refer to EM-123, "

P O Inspection for Leaks
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 MA-19, "
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.
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-131, "
Diagnosis Pro-
cedure" (EURO-OBD), EC-484, "Diagnosis Procedure" (WITHOUT EURO-OBD).
 Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-6, "
Inspection".
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release the fuel pressure. Refer to EC-377, "
Inspection" (EURO-OBD), EC-681, "Inspection" (WITHOUT
EURO-OBD).
b. Remove intake manifold. Refer to EM-29, "
Exploded View".
c. Disconnect ignition coil and injector harness connectors. Refer to EM-47, "
Exploded View".
3. Remove intake valve timing control solenoid valve. Refer to EM-50, "
Exploded View".
4. Crank engine, and then make sure that engine oil comes out
from intake valve timing control solenoid valve hole (A). End
crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
 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.

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.

NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-127, "
Cylinder
Block".
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Never allow gasket debris to enter passages for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.
 If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gasket.
2. Tighten cylinder head bolts in numerical order as shown with the
following procedure to install cylinder head.
CAUTION:
If cylinder head bolts are re-used, check their outer diame-
ters before installation. Follow the “Cylinder Head Bolts
Outer Diameter” measurement procedure.
