      *b Black
      *c Intake Side
      *d Exhaust Side
      NOTE:

      Make sure to install each valve stem oil seal to the correct side. Installing an intake valve stem oil seal to the exhaust side or installing an exhaust valve stem oil seal to the intake side can cause installation problems later.

      HINT: 

      The intake valve stem oil seals are gray and the exhaust valve stem oil seals are black.

    2. Using SST, push in the 6 intake valve stem oil seals to the intake valve guide bush.

      NOTE:
      • Failure to use SST will cause the intake valve stem oil seal to be damaged or improperly seated.
      • Do not push in the intake valve stem oil seal at an angle.
  7. INSTALL EXHAUST VALVE STEM OIL SEAL 

    HINT: 

    Use the same procedure as for the intake side.
