Valve seats, reworking (refacing): Notes

NOTE:
  • The valve seats should only be reworked just enough to produce a good seating pattern.
  • Calculate the maximum permissible reworking dimension before reworking.
  • If the reworking dimension is exceeded, the function of the hydraulic lifters can no longer be guaranteed and the cylinder head should be replaced.
