c. Press-fit the rear oil seal using a suitable drift (A) with outer
diameter 113 mm (4.45 in) and inner diameter 90 mm (3.54 in).
• Press-fit to the specified dimensions as shown.
CAUTION:
• Do not touch the grease applied to the oil seal lip.
• Be careful not to damage the rear oil seal mounting partof oil pan (upper) and cylinder block or the crankshaft.
• Press-fit straight and check that oil seal does not curl or tilt.
d. After press-fitting the rear oil seal, completely wipe off any liquid gasket protruding to rear end surface side.
3. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, includi ng 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. 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.

INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check there are no fuel leaks at connection points. Refer to.
NOTE:
Use mirrors for checking points out of clear sight.
2. Start the engine. With engine speed increased, check again that there are no fuel leaks at connection
points.
• Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
129, "Description".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-130, "
Description".
CAUTION:
Do not touch the engine immediately after stopping, as the engine becomes extremely hot.
