   3. Inspect the valve head for signs of burning, erosion, warpage and cracking.
      
   4. Inspect the valve margin for wear.
      

1. Repeat the appropriate removal steps for all of the other valves.
   

ASSEMBLY

1. NOTE: If installing the original valves, make sure the valves are installed in the same position from which they were removed.

   Lubricate with clean engine oil and install the valve.
   

1. NOTE: Use valve stem seal pliers (such as BeTooll HW0107 or equivalent).

   • Lubricate the valve stem seal with clean engine oil.
