Minimum dimensions
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2004 Audi A6, 2003 Audi S6, 2003 Audi A6, 2002 Audi S6, and 2002 Audi A6. However, it is still accessible from the selected car via links, so may be relevant.
MINIMUM DIMENSIONS: DISTANCE BETWEEN END OF VALVE STEM AND TOP SURFACE OF CYLINDER HEAD
| Outer intake valve | Center intake valve | Exhaust valve |
|---|---|---|
| 34.0 mm (1.338 in.) | 33.7 mm (1.326 in.) | 34.4 mm (1.354 in.) |
The measured distance minus the minimum dimension equals the maximum permissible refacing dimension.
Example:
Outer intake valve
Measured distance 34.4 mm (1.354 in.)
Minimum dimension -34.0 mm (1.338 in.)
Maximum permissible refacing =0.4 mm (0.0157 in.)
NOTE:
If the measured distance is less than the minimum dimension, repeat the measurement with new valves or replace the cylinder head.
