6) Install valve to valve guide.Before installing valve to valve guide, apply engine
oil to stem seal, valve guide bore and valve stem.
7) Install valve spring and spring retainer. Each valve spring has top end (large-pitch end (1))
and bottom end (small-pitch end (2)). Be sure to
position spring in place with its bottom end (small-
pitch end) facing the bottom (valve spring seat side). 8) Using special tools (Val
ve lifter), compress valve
spring and fit two valve cotters (1) into groove in
valve stem.
NOTE
When compressing the valve spring, be
carefully to free from damage in inside face
of tappet installing hole.

Installation1) Install clamps to marked location on pipes. If clamp is deformed, its claw is bent or broken, replace it with
new one.
2) Install pipes with pipe clamps to vehicle.
3) Connect fuel hoses and pipes to each pipe referring to “Fuel Hose Disconnecting and Reconnecting”.
4) Connect negative cable at battery.
5) With engine OFF, turn igniti on switch to ON position
and check for fuel leaks.
Fuel Injector On-Vehicle InspectionS7RS0B1706007
1) Using sound scope (1) or such, check operating sound of injector (2) when engine is running or
cranking.
Cycle of operating sound should vary according to
engine speed.
If no sound or an unusual sound is heard, check
injector circuit (wire or coupler) or injector.
2) Disconnect connector (1) from injector, connect ohmmeter between terminals of injector and check
resistance.
If resistance is out of specification, replace.
Resistance of fuel injector
11.3 – 13.8 Ω at 20 °C, 68 °F
3) Connect connector to injector securely.

Installation
Reverse removal procedure for installation noting the
following.
• Replace injector O-ring (1) with new one using care not to damage it.
• Check if cushion (2) is scor ed or damaged. If it is,
replace with new one.
• Apply thin coat of fuel to O-rings (1) and then install injectors (3) into delivery pipe (4) and cylinder head.
Make sure that injectors rota te smoothly (6). If not,
probable cause is incorrect installation of O-ring.
Replace O-ring with new one.
• Tighten delivery pipe bolts (5) to specified torque and make sure that inject ors rotate smoothly.
Tightening torque
Fuel delivery pipe bolt (a): 25 N·m (2.5 kgf-m, 18.0
lb-ft)
• After installation, with engine OFF and ignition switch ON, check for fuel leaks around fuel line connection.Fuel Injector InspectionS7RS0B1706009

Ignition Spark TestS7RS0B1804004
1) Remove air cleaner assembly with air intake pipe.
2) Disconnect all injector couplers from injectors.
WARNING!
Without disconnection of injector couplers,
combustible gas may come out from spark
plug holes during this test and may get
ignited in engine room.
3) Remove spark plug and check it for condition and
type referring to “Spark Plug Inspection”.
4) If OK, connect ignition coil coupler to ignition coil assembly and connect spark plug to ignition coil
assembly or high-tension cord. Ground spark plug. 5) Crank engine and check if each spark plug sparks.
6) If no spark is emitted, inspect the related parts as
described in “Ignition System Symptom Diagnosis”.
