Valve Seat (DOHC)
- 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, the first cut should be 15 degrees. The second cut should be 45 degrees to obtain correct seat angle.
- After cutting valve seats to correct angles, valve seat should be lapped in 2 steps. Use a course compound in the first step and a fine compound in the second step.
