Valve Seat (DOHC & 16-Valve SOHC)
- Inspect valve seats for damage or wear. If valve seat rework is necessary, use 2 cutters to obtain required angles. On intake and exhaust valves, first cut should be 15 degrees. Second cut should be 45 degrees to obtain correct seat angle.
- After cutting valve seats to correct angles, lap valve seat in 2 steps. Use a course compound for first step and a fine compound for second step.
