INSPECT VALVE CLEARANCE
Set No. 1 cylinder to TDC/compression.
(1) Turn the crankshaft pulley, and align its groove with
timing mark "0" of the timing chain cover.
(2) Check that the point marks of the camshaft timing
sprocket and VVT timing sprocket are in straight line
on the timing chain cover surface as shown in the
illustration.
Check only the valves indicated.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.
(2) Record the out–of specification valve clearance
measurements. They will be used later to determine
the required replacement adjusting shim.
Valve clearance (Cold):
Intake 0.15 – 0.25 mm (0.006 – 0.010 in.)
Exhaust 0.25 – 0.35 mm (0.010 – 0.014 in.)
