Frequently Asked Questions (FAQs)

1. Can you reuse rocker arm bolts?

Yes, rocker arm bolts are typically strong enough to be reused if they are in good condition and have not been previously over-torqued.

2. Why do my rocker arms keep coming loose?

There are a few possible reasons for rocker arms coming loose. One common cause is inadequate initial tightening or attempts to adjust the rocker arms incorrectly. It is essential to ensure proper tightening of rocker arm bolts to prevent them from coming loose.

3. Which bolts cannot be reused?

Bolts that have been galvanized or pretensioned, such as F3125 Grade A490 bolts, should not be reused. These bolts may not provide the necessary strength and reliability if reused.

4. Can you reuse bolts that have been torqued?

In general, it is possible to reuse bolts that have not been torqued beyond their yield strength. However, if over-torquing is suspected or confirmed, it is not recommended to reuse these fasteners as they may not provide a durable and secure joint.

5. What are the torque specs on rocker arm?

The torque specifications for rocker arm bolts can vary depending on the specific engine. In general, exhaust valve rocker arm bolts are tightened to 30 N·m (22 lb ft), and intake valve rocker arm bolts are also tightened to 30 N·m (22 lb ft). It is important to consult the specific engine's service manual for accurate torque specifications.

6. Can I tighten a loose rocker arm?

If a rocker arm is loose, it may be due to a loose stud. To fix this, refer to the service manual to find the correct torque specification for the stud and retighten it accordingly. Additionally, it is important to check the valve lash according to the service manual to ensure proper adjustment.
