Start by locating the distributor, typically near the top of the engine. Behind it, you may find one or more oil galley plugs. Additionally, inspect the sides of the engine block, as some vehicles have galley plugs located there as well.

Take note of the specific positions of these plugs, as they may differ depending on the make and model of your vehicle. Once you have identified the location, you can proceed to the next step of removing the oil galley plugs.

Step 02: Preparation and Safety

Before you begin removing the oil galley plugs from your vehicle engine, gather the necessary tools and materials and take the necessary safety precautions.

  • Safety should be your top priority, so ensure you’re wearing safety glasses and gloves to protect yourself from any potential hazards.
  • Additionally, gather the tools and materials you’ll need for this task, such as a suitable wrench or socket set to remove the plugs.
  • It’s also advisable to have some lubricating oil on hand to loosen any stubborn plugs.
  • If you encounter particularly stubborn plugs, a propane torch can be used to apply heat and aid in their removal.

Step 03: Select the Right Tool

When removing oil galley plugs from your vehicle’s engine, you’ll need to select the appropriate tool for the job. The choice of tool depends on the location and design of the plugs.

  • If you have plugs with a hexagonal recess, a modified Allen wrench is a good option. This wrench is designed to fit into the recess and provide a secure grip for turning the plug.
  • For plugs that require a socket, you may need a specialized socket set. These sets often come with various sizes and shapes of sockets to fit different plug designs.
  • Lastly, if your plugs have a square recess, a pipe plug socket is the right tool. This socket has a square shape that matches the recess, allowing for easy plug removal.

Choose the tool that matches your plug design to ensure a successful removal process.

Step 04: Heat the Plugs

Heat the oil galley plugs using a propane torch to aid in their removal from your vehicle engine. This step is crucial when dealing with stubborn plugs that are difficult to remove.

By applying heat evenly to the plugs, you can make the removal process much easier. Start by using a propane torch and carefully direct the flame toward the plugs. Make sure to heat them until they turn cherry red.

This heat will cause the plugs to expand, helping to break the rust and loosen them from their position. However, it’s important to exercise caution and take fire safety measures when using a torch. Always keep a fire extinguisher nearby in case of emergencies.

Step 05: Cool with Lubricants

After heating the plugs and expanding them to break the rust, you can now cool them with lubricants to further facilitate the removal process. Once the plugs have cooled slightly, apply a generous amount of WD40 to the threads. The purpose of this step is twofold.

First, the lubricant will help to loosen any remaining rust that may still be clinging to the threads. This will make it easier to unscrew the plugs from the engine.

Second, the lubrication provided by WD40 will reduce friction between the threads and the surrounding metal, making it smoother and more effortless to turn the plugs.

Step 06: Slow and Steady

Now start the actual process of removing the plugs.

Use your Allen Wrench to slowly and steadily unscrew the plugs. You can also use specialized socket sets or pipe plug sockets to fit the plugs snugly. Apply firm but controlled pressure in a counterclockwise direction. Turn the plugs slowly and steadily to prevent damage to the threads.

This minimizes the risk of stripping or breaking the plugs. By maintaining a steady pace and being patient, you can effectively remove the oil galley plugs without any complications.

Step 07: Avoid Over-Tightening (Optional 1)

Some vehicle mechanics suggest that, in certain cases, tightening the plugs slightly before attempting removal can help break them loose. If you try this method, be gentle and ensure you don’t over-tighten.

To avoid over-tightening, gently tighten the oil galley plugs in a clockwise direction before attempting removal. The goal is to create a small amount of tension that can help break the plug free.

Remember to be cautious and avoid over-tightening, as this can lead to stripped threads or other complications. Once you have gently tightened the plug, you can proceed with attempting to remove it following the above steps.

Step 08: Alternative Tool (Optional 2)

If the plugs still won’t budge after following the above steps, a reverse drill bit can be used to make a groove for a screwdriver. Just be careful not to damage your engine.

The reverse drill bit is designed to rotate in the opposite direction of a regular drill bit, which can help loosen stubborn plugs. Insert the reverse drill bit into the center of the plug and slowly drill in a counterclockwise motion. As the bit rotates, it may catch onto the plug and start to loosen it.

Alternatively, you can carefully drill into the plug using a regular drill bit. Create a shallow groove in the plug and then insert a screwdriver into the groove to turn and remove the plug. Take your time and exercise caution to prevent any damage to your engine block.
