Frequently Asked Questions (FAQs)

1. What does valve lock do in an engine?

Valve locks in an engine serve the purpose of keeping the valves in place and preventing them from making contact with the pistons inside the cylinders. They handle the valve spring pressure and contribute to the overall performance of the valvetrain.

2. Can you reuse valve locks?

Valve locks, also known as keepers, are typically not considered reusable components. They play a crucial role in maintaining the longevity of the valvetrain. It is recommended to replace them when necessary to ensure optimal performance and prevent any potential issues.

3. Does more valves mean more power?

Having more valves in an engine can result in increased power output. This is because additional valves provide a larger valve area, improving the flow of intake and exhaust gases. This enhances combustion, volumetric efficiency, and overall engine performance. Furthermore, multi-valve geometry allows for optimal placement of the spark plug within the combustion chamber for improved flame propagation.

4. What are the three types of valve retainers?

There are three types of valve retainers commonly used: 10° Titanium Retainers with a spring diameter of 1.625 inches, 7° Lightweight Tool Steel Retainers with a spring diameter of 1.055 inches, and 10° Steel Retainers with a spring diameter of 1.095 inches. These retainers are essential components that hold the valve springs in place.

5. Do I need to shim my valve springs?

Valve springs may require shimming if the installed height falls outside the allowed 0.020-inch variance. If the distance is too short, machining of the valvespring seat may be necessary. If the distance is too long, shims can be added to achieve the correct installed height. It is important to ensure that the valve springs are properly shimmed to maintain the correct valvetrain geometry and optimal engine performance.
