Valve Seats

  1. Inspect valve seats for damage or wear. If valve seat rework is necessary, use 3 cutters to obtain required angles. For exhaust valves, the first cut should be 15 degrees. The second cut should be 75 degrees. The third cut should be 45 degrees to obtain correct seat angle.
  2. For intake valves, the procedure is the same except the second cut should be 60 degrees. After cutting valve seats to correct angles, valve seat should be lapped in 2 steps. The first step should be made using a course compound. The final lapping procedure should be done using a fine compound.
