e. After installing front timing chain case, check the surface height
difference between the following parts on the oil pan (upper)
mounting surface.
If not within the standard, repeat the installation procedure.
15. Install right and left intake valve timing control covers as follows:
a. Install new seal rings in shaft grooves.
b. Apply a continuous bead of liquid gasket with the tube presser [SST: WS39930000 ( — )] to intake valve timing control cov-
ers as shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
c. Install new collared O-rings in front timing chain case oil hole (left and right sides).
d. Being careful not to move seal ring from the installation groove, align dowel pins on front timing chain case with holes to install intake valve timing control covers.
e. Tighten mounting bolts in numerical order as shown in the fig- ure.
16. Install oil pans (upper and lower). Refer to EM-30, "
OIL PAN AND OIL STRAINER" .

INSPECTION AFTER INSTALLATION
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 GI-48, "
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
leakage 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 chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness.
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.

Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 4 jour- nals of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
three locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on a dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
