Valve Measurement Step 3
- Turn the crankshaft pulley 2/3 revolution (240°) and measure the clearance of No.2 (IN) and No.6 (IN) and No.2 (EX) and No.4 (EX) valves.
- Check that the valve lifters on the No.2 cylinder are loose.
- Measure only the valves indicated in the illustration.
- Record the measurements which are out of specification. They will be used later to determine the required replacement shims.
