For 1990-2009 cars

#### Tools Required

• | J 8062 Valve Spring Compressor

• | J 43184 Valve Spring Compressor Adaptor

1. Use a steel square and measure the deviation of the valve spring.

Valve Spring Deviation
2.0 mm (0.079 in)

2. If the deviation of any valve spring is greater than the specified maximum, the valve spring must be replaced.
3. Use a Vernier caliper and measure the free length of the valve spring.

Valve Spring Free Length
36.83 mm (1.4500 in)

4. If the free length of any valve spring is not within specifications, the valve spring must be replaced.
5. Inspect the valve spring seating surface of the valve spring seats for wear or gouging. Replace as required.
6. Temporarily install the valves into the cylinder head.
7. Use the following steps to measure valve runout:

7.1. | Apply a dab of Prussian blue on the entire valve face. Seat the valve but do not rotate it. The Prussian blue traces transferred to the valve seat are an indication of concentricity of the valve seat.

7.2. | Clean all traces of Prussian blue.

7.3. | Apply a dab of Prussian blue on the valve seat and repeat the check. The traces of Prussian blue transferred to the valve face indicates valve face concentricity.

7.4. | Recondition the valve seat or replace the valves, if required.

8. Install the spring seat.
9. Use a valve seal installer and install the new valve seals. Fully seat the seals on the valve guides.

Important: Pay close attention when installing the valve seals. Never tap or hit the seal installer with a hammer, only install the seals by hand.

10. Install the spring.
11. Install the retainer.
12. Compress the valve spring. Use theJ 8062 and theJ 43184 .
13. Install the valve keepers.
14. Slowly release theJ 8062 from the valve/spring assembly.
15. Use a plastic faced hammer and lightly tap the valve stem tip and inspect for proper valve key seating.
