REAR TIMING CHAIN CASE
8. Use scraper to remove all traces of old liquid gasket from rear
timing chain case, and opposite mating surfaces.
• Remove old liquid gasket from bolt hole and thread.
INSTALLATION
1. Install rear timing chain case as follows:
a. Install new O-rings onto cylinder block.
CAUTION:
Do not reuse O-rings.
b. Install new O-rings to cylinder head and camshaft bracket
(No. 1).
CAUTION:
Do not reuse O-rings.
c.
Apply liquid gasket using Tool to rear timing chain case back side as shown.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-21, "Recommended Chemical Prod-
.
CAUTION:
• For “A”, completely wipe off liquid gasket covering the area shown.

• Apply liquid gasket on installation position of water pump and cylinder head very completely.
d. Align rear timing chain case with dowel pins (right and left) on cylinder block and install rear timing chain
case.
• Make sure O-rings stay in place during installation to cylinder block, cylinder head and camshaft bracket
(No. 1).
CAUTION:
Do not reuse O-rings.
e. Tighten bolts in numerical order as shown.
• There are two type of bolts with different torque specifications.
Refer to the following for installing bolts.
f.
After all bolts are tightened, retighten them to the specified torque in numerical order as shown.
• If liquid gasket protrudes, wipe it off immediately.

REAR TIMING CHAIN CASE
g. After installing rear timing chain case, check the surface height
difference between following parts on oil pan (upper) mounting
surface.
• If not within the standard, repeat the installation procedure.
2. Install water pump with new O-rings, if removed. Refer to
CO-21, "Removal and Installation"
.
CAUTION:
Do not reuse O-rings.
3. Install timing chains and related components. Refer to
EM-59, "Removal and Installation"
"Removal and Installation (Secondary Timing Chain Tensioner)"
.
4. Install front timing chain case. Refer to
EM-51, "Removal and Installation"
.
5. Install oil pan (upper) and (lower). Refer to
EM-34, "Removal and Installation"
INSPECTION AFTER INSTALLATION
• 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-12, "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 and 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, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
