VALVE CLEARANCE
INSPECTION
HINT:
Inspect and adjust the valve clearance when the engine is cold.
1. REMOVE RH FENDER APRON SEAL
2. DRAIN ENGINE COOLANT
3. REMOVE V-BANK COVER
(a) Using a 5 mm hexagon wrench, remove the 3 cap nuts.
(b) Loosen the V-bank cover fastener counterclockwise.
(c) Remove the V-bank cover.
4. REMOVE AIR INTAKE CHAMBER ASSEMBLY (See
page EM-31)
5. REMOVE IGNITION COILS
6. DISCONNECT UPPER RADIATOR HOSE FROM WA-
TER OUTLET
7. REMOVE CYLINDER HEAD COVERS
(See page EM-31)
8. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with the
timing mark º0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 (IN and EX) are
loose.
If not, turn the crankshaft 1 revolution (360°) and align the mark
as above.
9. INSPECT VALVE CLEARANCE
(a) Check only those valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record out of specification valve clearance mea-
surements. They will be used later to determine the
required replacement adjusting shim.
Valve clearance (Cold):
Intake0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust0.25 - 0.35 mm (0.010 - 0.014 in.)
