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

   NOTE:

   Pay attention when installing the intake valve stem oil seal and 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.

   HINT: 

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

2. Using SST, push in the intake valve stem oil seals.

   *a	Correct
   *b	Incorrect

   • SST: 09201-41020 
   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.

HINT: 

Use the same procedure as for the intake side.

1. Sufficiently apply engine oil to the tip area of the exhaust valve shown in the illustration.
