Valve Clearance: Specifications

The valve clearance measured on cold engines (approximately 20°C) should be:
Inlet valve 0.20 ± 0.03 mm
Exhaust valve 0.40 ± 0.03 mm

Note: The tolerances are less at setting! When checking the valve clearance through the plug hole the tolerances are larger.

Differences in valve clearance for different engines / ambient temperatures:
- 0.01 mm at 15° C
+ 0.01 mm at 25° C
+ 0.02 mm at 30° C
+ 0.03 mm at 35° C
+ 0.04 mm at 45° C
