- Remove the valve covers. For additional information, refer to Valve Cover - LH and Valve Cover - RH .
- Use a feeler gauge to measure the clearance of each valve and record its location. A mid-range clearance is the most desirable:
- Intake: 0.15-0.25 mm (0.006-0.01 in)
- Exhaust: 0.300-0.400 mm (0.0118-0.0157 in)
NOTE:
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.
