Check
- Remove the following items:
- Refer to: Valve Cover RH .
- Refer to: Valve Cover LH .
-
NOTE: Engine must be at room temperature before measuring. The valve clearance must be measured with the camshaft at base circle. The engine will have to be rotated with the crankshaft pulley bolt to bring each valve to base circle.
- Measure the clearance of each valve and record its location. A midrange clearance is the most desirable: Use the General Equipment: Feeler Gauge
- Intake: 0.15-0.25 mm (0.006-0.01 in)
- Exhaust: 0.360-0.460 mm (0.0142-0.0181 in)
-
NOTE: The number on the valve tappet reflects the thickness of the valve tappet. For example, a tappet with the number 3.310 has the thickness of 3.31 mm (0.13 in).
If any of the valve clearances are out of specification, select new tappets using this formula: tappet thickness = measured clearance + the base tappet thickness - most desirable thickness. Select the tappets and mark the installation location.
Adjustment
-
NOTE: The following step is only necessary if adjustment is required.
Remove the camshafts and install the selected new tappets. Refer to: Camshafts .
