Frequently Asked Questions
What is the difference between hydraulic roller lifters and flat tappet lifters?
Hydraulic roller lifters use a rolling element (roller) that contacts the cam lobe, reducing friction and allowing for more aggressive cam profiles. They also have a hydraulic plunger that automatically adjusts lash, eliminating the need for periodic valve adjustments. Flat tappet lifters have a sliding contact surface and require manual lash setting. Roller lifters generally offer better performance, durability, and ease of maintenance, but they are more expensive.
Can I use hydraulic roller lifters with any camshaft?
No, hydraulic roller lifters require a camshaft specifically designed for roller lifters. The cam lobe profile is different from flat tappet cams, and using mismatched components can cause rapid wear or failure. Always ensure your camshaft is compatible with hydraulic roller lifters, typically indicated by the manufacturer.
How do I set the preload on hydraulic roller lifters?
Preload is set by adjusting the rocker arm to compress the lifter plunger a specific amount, usually between .020 and .060 inches. This is done by tightening the rocker bolt to a specified torque after the lifter has bled down. Follow the lifter manufacturer’s instructions for the exact preload range. Improper preload can cause noise or performance issues.
Are link-bar lifters better than drop-in lifters?
Link-bar lifters are generally preferred for performance applications because they maintain alignment and reduce the risk of lifter spin, which can cause wear. Drop-in lifters (without tie bars) rely on the lifter bore for alignment and can be prone to spinning in high-RPM or high-spring-pressure setups. For street and mild builds, drop-in lifters can be adequate, but link-bar designs offer added reliability.
How often should I replace hydraulic roller lifters?
Hydraulic roller lifters are durable and can last the life of the engine under normal driving conditions. However, if you experience abnormal noise, wear, or performance changes, they should be inspected. In high-performance applications, some builders replace lifters during engine rebuilds for peace of mind. Always follow the manufacturer’s service recommendations.
