Valve Seat (SOHC)

  1. Inspect valve seats for damage or wear. If exhaust valve seat rework is necessary, use 3 cutters to obtain required angles. The second cut should be 75 degrees for Samurai and Swift or 60 degrees for Sidekick. 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 for all models. 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.
