The answer is yes, you do need to break in a hydraulic roller cam, just like any other type of camshaft. In this step-by-step guide, we will walk you through the process of breaking in a hydraulic roller cam.

Before we dive into the steps, let’s first understand why breaking in a hydraulic roller cam is necessary. The purpose of breaking in a camshaft is to ensure that the cam lobes and lifters mate properly. During the break-in process, the cam lobes and lifters wear against each other, creating a smooth and precise fit. This is crucial for optimal performance and longevity of the camshaft.

Now, let’s get into the step-by-step guide. The first step is to make sure you have the right tools and equipment. You will need a torque wrench, a distributor wrench, a timing light, and a set of feeler gauges. Additionally, you will need the manufacturer’s recommended break-in oil and assembly lube.

Once you have gathered all the necessary tools and equipment, it’s time to prepare the engine for the break-in process. Start by removing the spark plugs and disabling the ignition system. This will prevent the engine from starting during the break-in procedure. Next, remove the valve covers and inspect the valve train for any signs of damage or wear. If everything looks good, proceed to the next step.

Now it’s time to install the hydraulic roller camshaft. Apply a generous amount of assembly lube to the cam lobes and lifters. This will provide lubrication during the break-in process. Carefully install the camshaft, making sure it is properly aligned with the timing marks. Torque the camshaft bolts to the manufacturer’s specifications.

With the camshaft installed, it’s time to adjust the valve lash. This step is crucial for proper operation of the hydraulic roller cam. Using the feeler gauges, adjust the valve lash to the manufacturer’s specifications. This will ensure that the valves open and close at the correct timing.

Once the valve lash is adjusted, it’s time to prime the oil system. Fill the engine with the manufacturer’s recommended break-in oil and turn the engine over using the starter motor. This will circulate the oil and ensure proper lubrication during the break-in process. Check for any oil leaks and make sure the oil pressure is within the recommended range.

Now it’s time to start the engine. Make sure the ignition system is still disabled and crank the engine for about 20 seconds. This will allow the lifters to pump up and establish proper contact with the cam lobes. After 20 seconds, shut off the engine and let it cool down for about 20 minutes. Repeat this process three more times, allowing the engine to cool down between each start.

After the break-in procedure is complete, it’s time to adjust the valve lash one final time. This will ensure that the valves are properly seated and the camshaft is fully broken in. Once the valve lash is adjusted, you can reassemble the valve covers and install the spark plugs.

In conclusion, breaking in a hydraulic roller cam is an essential step in ensuring optimal performance and longevity. By following this step-by-step guide, you can confidently break in your hydraulic roller cam and enjoy the benefits of a properly mated camshaft and lifters. Remember to always refer to the manufacturer’s instructions and specifications for your specific camshaft.
