Benefits of Using Roller Rockers with Hydraulic Lifters
Roller rockers and hydraulic lifters are aftermarket upgrades to provide several benefits. The following are the benefits of using roller rockers with hydraulic lifters:
Roller rockers reduce friction between the valve stem and the rocker’s arm, which can help to improve overall engine performance and efficiency.
Hydraulic lifters also help to reduce friction by providing a constant and smooth lift for the valves.
Roller rockers are more durable than traditional stamped steel rocker arms and can withstand the high forces and pressures of a high-performance engine.
When used in conjunction with hydraulic lifters, which also have a longer lifespan than solid lifters, these upgrades can help to extend the life of an engine.
Improved Valve Train Stability:
Roller rockers and hydraulic lifters work together to provide a stable and consistent lift for the valves, which can help to reduce valve float and improve valve train stability.
This can result in better overall engine performance and reduced wear on the valve train components.
By reducing friction and improving valve train stability, roller rockers and hydraulic lifters can help to increase the power output of an engine.
This can be especially beneficial for high-performance engines that require maximum power and efficiency.
Choosing the Right Roller Rockers for Your Hydraulic Lifters
Here are some factors to consider when selecting roller rockers for hydraulic lifters:
Roller rockers can be made from various materials, including aluminum, steel, and titanium.
Each material has its own advantages and disadvantages in terms of durability, weight, and cost.
It is essential to choose roller rockers made from high-quality materials that are suitable for your engine’s requirements.
Roller rockers are available in different ratios, such as 1.5:1 and 1.6:1. The ratio refers to the amount of valve lift that is achieved for every unit of camshaft lift.
It is essential to choose the right ratio based on your engine’s requirements and the camshaft you are using.
Roller rockers are available in various designs, including full roller, roller tip, and needle-bearing.
Each design has its own advantages and disadvantages in terms of performance, cost, and complexity.
It is important to choose a design that is suitable for your engine’s requirements and budget.
Brand and Quality:
Roller rockers are available from various brands and manufacturers, and the quality can vary significantly.
It is essential to choose a reputable brand that has a proven track record of producing high-quality roller rockers that are suitable for your engine’s requirements.
Roller rockers can be challenging to install correctly, and it is essential to follow the manufacturer’s instructions carefully.
Ensure that the roller rockers are properly lubricated and torqued to the correct specifications to prevent damage to the engine.
Installation Process for Roller Rockers and Hydraulic Lifters
Here’s a comprehensive guide on how to install roller rockers and hydraulic lifters.
Tools You’ll Need:
Before starting, make sure you have the following tools:
- Torque wrench
- Wrench set
- Rocker arm removal tool
- Hydraulic lifter removal tool
- Gasket scraper
Step 1: Remove the Old Rocker Arms
To begin, remove the valve covers and locate the rocker’s arms. Then, use a rocker arm removal tool to remove the old rocker arms.
Make sure to keep the rocker arms in order to reinstall them correctly later.
Step 2: Install the Roller Rockers
Install the roller rockers in the same order as the old rocker arms. Make sure to follow the manufacturer’s instructions for proper installation torque specifications.
Use a torque wrench to ensure that the bolts are tightened to the correct torque settings.
Step 3: Install the Hydraulic Lifters
Remove the old hydraulic lifters using a lifter removal tool. Then, install the new hydraulic lifters in the same location as the old ones.
Make sure to use a lubricant on the lifters before installation.
Step 4: Install the Pushrods and Adjust the Valve Lash
Install the pushrods and adjust the valve lash according to the manufacturer’s specifications.
Make sure to follow the recommended torque settings when tightening the bolts.
Step 5: Reinstall the Valve Covers
Reinstall the valve covers and start the engine to ensure that everything is running smoothly. Check for any oil leaks or unusual noises.
Potential Issues to Look Out for When Using Roller Rockers with Hydraulic Lifters
When using roller rockers with hydraulic lifters, there are a few potential issues that you should be aware of. Here are some of the most common issues to look out for
Incorrect rocker arm ratio:
If the rocker arm ratio is incorrect, it can cause excessive valve lift, leading to valve float or even contact between the valve and piston.
Make sure to use the recommended rocker arm ratio for your engine.
Poor valve train geometry:
Poor valve train geometry can cause uneven valve lift, leading to excessive wear on the valve stems and guides.
This can also cause valve float or contact between the valve and piston. Check the valve train geometry and adjust it.
Improper lifter preload:
If the lifter preload is incorrect, it can cause noise or excessive wear on the lifters. Make sure to follow the manufacturer’s instructions for proper lifter preload.
Roller rockers require more oil than stock rocker arms. If the oiling system is insufficient, it can cause premature wear on the rockers and lifters.
Make sure to use an oiling system that is designed for roller rockers.
Valve cover clearance:
Roller rockers are generally taller than stock rocker arms, which can cause clearance issues with the valve covers.
Make sure to use valve covers that are designed to accommodate roller rockers.
Maintenance Tips for Roller Rockers and Hydraulic Lifters
Roller rockers and hydraulic lifters are essential components in high-performance engines.
To ensure that they perform optimally and last longer, here are some maintenance tips to follow:
Regularly inspect the roller rockers and hydraulic lifters for signs of wear, damage, or excessive play.
Look for any abnormal wear patterns, such as flat spots or galling, which can indicate problems with the valve train geometry or insufficient oiling.
Roller rockers require more lubrication than stock rocker arms. Make sure to use high-quality engine oil that is formulated for high-performance engines.
Also, consider using an oiling system that is specifically designed for roller rockers.
Adjust Valve Lash:
Make sure to adjust the valve lash according to the manufacturer’s specifications.
A proper valve lash adjustment ensures that the hydraulic lifters operate correctly and prevents valve float or excessive wear on the valve stems and guides.
Proper Installation Torque:
Follow the manufacturer’s instructions for proper installation torque specifications when installing roller rockers and hydraulic lifters.
Using the wrong torque settings can cause damage to the components and affect the engine’s performance.
