      Intake Side

      *b

      Exhaust Side

      *c

      Gray

      *d

      Black

      Apply a light coat of engine oil to 12 new valve stem oil seals.

      Note:

      Pay close attention when installing the intake valve stem oil seal or exhaust valve stem oil seal. For example, installing the intake valve stem oil seal to the exhaust side or installing the exhaust valve stem oil seal to the intake side can cause installation problems later.

      Tip:

      The intake valve stem oil seal is gray and the exhaust valve stem oil seal is black.
