How to Install Pushrod Guide Plates for Your Engine Build

If you’re planning an engine build, you know that there are countless components to consider. Pushrod guide plates are a small but essential part of any engine, providing a precise path for pushrods to follow. Installing guide plates properly can help to ensure that your engine runs smoothly and efficiently. In this article, we’ll provide a step-by-step guide on how to install pushrod guide plates.

What are Pushrod Guide Plates?

Pushrod guide plates are small metal plates that are installed on the cylinder head of an engine. They provide a precise path for pushrods to follow, which helps to ensure that the pushrods don’t flex or bend as the engine operates. Guide plates are typically used in high-performance engines, as they provide increased stability and precision.

Why Do You Need Pushrod Guide Plates?

Pushrod guide plates are essential components in any engine build, as they help to ensure that the pushrods follow a precise path. Without guide plates, pushrods can flex or bend as the engine operates, which can cause performance issues and potential damage to the engine. By installing guide plates, you can help to ensure that your engine runs smoothly and efficiently.

How to Install Pushrod Guide Plates

Before you begin installing pushrod guide plates, you’ll need to gather a few tools and materials. Here’s what you’ll need:

• Cylinder head gasket
• Pushrod guide plates
• Pushrods
• Cylinder head bolts
• Torque wrench
• Allen wrench
• Threadlocker
• Clean rags
• Engine assembly lube

Step-by-Step Guide to Install Pushrod Guide Plates

Now that you’ve gathered your tools and materials, it’s time to start installing pushrod guide plates. Here’s a step-by-step guide to follow:

Step 1: Remove the Cylinder Head

The first step in installing pushrod guide plates is to remove the cylinder head from the engine block. This will allow you to access the valve train components, including the pushrods and guide plates.

Step 2: Clean the Cylinder Head

Before you install the new guide plates, it’s important to clean the cylinder head thoroughly. Use a clean rag to wipe away any dirt, debris, or old gasket material that may be on the surface of the head.

Step 3: Install the Cylinder Head Gasket

Next, install the cylinder head gasket onto the engine block. Be sure to align the gasket properly, as this will help to ensure a good seal.

Step 4: Install the Guide Plates

Now it’s time to install the guide plates. Place each guide plate onto the cylinder head, making sure that they are properly aligned with the pushrod holes.

Step 5: Install the Pushrods

With the guide plates in place, you can now install the pushrods. Be sure to use the correct pushrod length for your engine and to apply engine assembly lube to the ends of the pushrods.

Step 6: Install the Cylinder Head

Once the pushrods are in place, you can re-install the cylinder head onto the engine block. Be sure to torque the cylinder head bolts to the manufacturer’s specifications and to use threadlocker on the bolts.

Step 7: Check Pushrod Clearance

After the cylinder head is torqued down, it’s important to check the pushrod clearance. Use an Allen wrench to rotate each pushrod, and make sure that it moves freely without binding or rubbing against the guide plate.

Step 8: Start the Engine

Once you’ve confirmed that the pushrods are moving freely, you can start the engine and check for any unusual noises or vibrations. It’s also a good idea to let the engine run for a few minutes to allow the oil to circulate throughout the engine.

Step 9: Final Adjustments

After the engine has run for a few minutes, it’s important to check the pushrod clearance again. Make any necessary adjustments to ensure that the pushrods are moving freely.

Step 10: Test Drive

Once you’ve confirmed that the pushrod guide plates are properly installed and adjusted, take your vehicle for a test drive. Pay attention to any unusual noises or vibrations and make any necessary adjustments before driving for an extended period.
