Valve Clearance: Adjustments
VALVE CLEARANCE INSPECTION AND ADJUSTMENT
NOTE:
Inspect and adjust the valve clearance when the engine is cold (Engine coolant temperature : 20°C±5°C(59 - 77°F)) and cylinder head is installed on the
cylinder block.
1. Remove the engine cover.
2. Remove air cleaner assembly.
3. Remove the surge tank.
4. Remove the cylinder head cover.
(1) Disconnect the ignition coil connector and remove the ignition coil.
(2) Remove the cylinder head cover.
5. Set the piston of the No.1 cylinder to TDC(Top Dead Center) position.
(1) Turn the crankshaft pulley clockwise and align its groove with the timing mark "T" of the timing chain cover.
(2) Check that the timing marks on the camshaft sprocket are in a straight line with the rocker cover mark for No. 1 cylinder TDC as shown in the
illustration.
NOTE:
If not, turn the crankshaft one revolution clockwise.
6. Inspect the intake and the exhaust valve clearance.
(1) With No. 1 cylinder at TDC the valve clearance can be measured as shown below.
Measurement method.
A. Using a thickness gauge, measure the clearance between the tappet and the base circle of camshaft.
B. Record the out-of-specification valve clearance measurements. They will be used later to determine the required adjusting tappet for
replacement.
