1.Remove the inlet manifold.
|
|
2.Remove all ignition coils.
|
|
3.Remove the rocker cover.
|
|
4.Turn the crankshaft clockwise until the notch on the pulley is lined up with the "T" mark
on the timing indicator.

5.Move the rocker arms on the No.1 and No.4 cylinders up and down by hand to determine which
cylinder has its piston at the top dead centre on the compression stroke. If both intake and
exhaust valve rocker arms have a valve lash, the piston in the cylinder corresponding to these
rocker arms is at the top dead centre on the compression stroke. 6.Valve clearance inspection and adjustment can be performed on rocker arms indicated
by white arrow mark when the No. 1 cylinder piston is at the top dead centre on the compression
stroke, and on rocker arms indicated by black arrow mark when the No. 4 cylinder piston is at
the top dead centre on the compression stroke. 7.Measure the valve clearance for intake side. If the valve clearance is not as specified, loosen the rocker arm lock nut and adjust
the clearance using a thickness gauge while turning the adjusting screw. Standard value (cold engine):
note |
Valve clearance check and adjustment is unnecessary for exhaust side due to auto lash
adjuster installed.

8.While holding the adjusting screw with a screwdriver to prevent it from turning, tighten
the lock nut to the specified torque. Tightening torque: 9 ± 1 N·m 9.Turn the crankshaft through 360 degree angle to line up the notch on the crankshaft
pulley with the "T" mark on the timing indicator. 10.Repeat steps (7) and (8) on other valves for clearance adjustment. 11.Install the rocker cover. 12.Install the ignition coils.
