Special Tools Required 

• Stem Seal Driver 07PAD-0010000

1. Coat the valve stems with new engine oil. Install the valves in the valve guides.
2. Check that the valves move up and down smoothly.
3. Install the spring seats on the cylinder head.
4. Install the new valve seals (A) using the 5.5 mm side of the stem seal driver (B).
   NOTE: The exhaust valve seal (C) has a black spring (D), and the intake valve seal (E) has a white or silver spring (F). They are not interchangeable.

8. Remove the valve spring compressor and the attachment.
9. Lightly tap the end of each valve stem two or three times with a plastic mallet (A) to ensure proper seating of the valve and the valve cotters. Tap the valve stem only along its axis so you do not bend the stem.
   NOTE: Be sure to raise the head off the work bench so the valve is not possibly damaged.
