      *a Press
      *b Mark
      *c Protrusion Height
      Standard protrusion height
      88.7 to 90.2 mm (3.492 to 3.551 in.)

      Note


      • Install the spark plug tube within 3 minutes after applying adhesive.

      • Do not start the engine within 1 hour after installation.

      • Do not deform the spark plug tube.

      • Be careful not to drip the adhesive.

  2. INSTALL VALVE SPRING SEAT

      *a Intake Side
      *b Exhaust Side
      *c Gray
      *d Black

      Apply a light coat of engine oil to new oil seals.
