How to Unstick Oil Rings: 6 Steps to Follow

In order to unstick an oil ring, you’ll need a few simple tools. These include a screwdriver, a hammer, and a chisel. Now, it is important to follow the following tips if you would like to remove an oil ring successfully:

• Step 1: Remove the spark plugs from the engine
• Step 2: Remove the oil pan
• Step 3: Take off the piston rings
• Step 4: Inspect the piston ring gaps
• Step 5: Clean the piston and ring grooves
• Step 6: Put the new ring in the groove

Step 1: Remove the Spark Plugs from the Engine

Start by locating the spark plug wires, which are usually connected to the top of the engine. Gently twist and pull each wire to disconnect it from the spark plug. This will expose the spark plugs.

Insert the screwdriver into the spark plug socket and turn it counterclockwise to loosen the spark plug. Once loose, carefully remove the spark plug from the engine. Be cautious not to drop the spark plug, as it can easily break. Repeat this process for each spark plug in the engine.

Step 2: Remove the Oil Pan

The oil pan is typically located underneath the vehicle’s engine. Look for the bolts around the perimeter of the oil pan and use the appropriate size wrench to loosen them. Start at one corner of the oil pan and work your way around, gradually loosening each bolt.

Keep track of the bolts as you remove them. They’ll need to be reinstalled later. Once all the bolts are loose, you can lift the oil pan off easily. Be careful not to damage the gasket between the oil pan and the engine block as you remove it.

Step 3: Take Off the Piston Rings

To begin removing the piston rings and unsticking oil rings in your vehicle, start by breaking the ring’s seal. To do this, use hammers and chisels. Position the chisel against the ring and apply pressure, twisting if necessary. This will help loosen the ring and make it easier to remove.

Once the seal is broken, it’s time to knock the ring out of its groove. Take the hammer and carefully tap the ring, starting at one end and working your way around. Be sure to use controlled force to prevent any damage to the piston or ring. With each tap, the ring should gradually come loose.

Continue this process until all the piston rings have been successfully removed.

Step 4: Inspect the Piston Ring Gaps

Now, it’s time for you to inspect the gaps in the piston rings in your vehicle. The gaps play a crucial role in the functioning of the rings, as they allow for proper oil control and compression.

• Start by carefully examining each ring gap to ensure it’s even on all sides.
• Using a feeler gauge, measure the width of the gap to determine if it falls within the manufacturer’s specifications.
• If the gap is too narrow, it can cause excessive friction and potential ring sticking.
• On the other hand, if the gap is too wide, it may result in oil leakage and reduced compression.
• Any irregularities or deviations from the recommended gap width should be addressed by replacing the piston rings. If the piston and ring grooves are okay then you can proceed to the next step.

Step 5: Clean the Piston and Ring Grooves

To clean the piston and ring grooves and unstick oil rings in your vehicle, grab a rag and some WD-40. Begin by applying the WD-40 to the rag and saturate it well.

Then, carefully wipe down the piston and ring grooves. Be thorough in your cleaning, ensuring that all of the oil and dirt are removed from the surfaces. Pay close attention to the grooves, as any buildup can prevent the rings from functioning properly.

Use gentle but firm pressure as you wipe, ensuring you reach all areas. Take your time to ensure thorough cleaning, as this step is crucial in preparing the piston and ring grooves for the installation of the new ring.

Step 6: Put the New Ring in the Groove

Start by ensuring that the ring is the correct size for the piston groove. Carefully position it, making sure that the gaps are evenly spaced around the circumference of the piston. This is crucial for optimal performance and oil control.

Once the ring is aligned, gently tap it into place using a hammer and chisel. Be careful not to damage the ring or the piston while doing this. The chisel can be used to guide the ring into the groove and ensure it’s seated correctly.

Apply even pressure to avoid any distortion or misalignment. Once the ring is securely in place, it’s ready for further assembly.

Tips for Preventing the Oil Ring from Sticking Again In The Future

There are a few tips that you can follow in order to prevent the oil ring from sticking again in the future:

Replace the Oil Every 3,000 Miles

The vehicle engine’s components must be properly lubricated and functioning by changing the oil regularly. Over time, the oil can become contaminated with dirt, debris, and other particles, leading to sludge formation. When this sludge accumulates on the oil ring, it sticks and impairs sealing.

By replacing the oil every 3,000 miles, you ensure fresh, clean oil circulates through the engine. This reduces the likelihood of sludge formation and prevents the oil ring from becoming stuck again.

Additionally, regularly changing the oil helps remove any built-up deposits, ensuring optimal engine performance and longevity.

Use High-Quality Oil

If you want to ensure that the oil ring doesn’t stick again in the future, ensure that you consistently use high-quality oil designed specifically for use in your vehicle. Using low-quality or incorrect oil can lead to deposits and sludge buildup, which can cause the oil ring to stick.

High-quality oil contains additives that help to keep the engine clean and prevent the formation of deposits. It also has a higher resistance to thermal breakdown, ensuring that it maintains its lubricating properties for longer periods.

When choosing oil, refer to your vehicle’s owner’s manual to determine the recommended viscosity and oil specifications.

Keep the vehicle Clean

Cleaning the engine is essential to vehicle maintenance and helps prevent various issues, including a stuck oil ring. Inspect the engine for any visible dirt or debris to clean your vehicle effectively. Use a soft brush or cloth to remove any buildup on the piston and surrounding areas gently.

Consider using a high-quality engine cleaner or degreaser to dissolve stubborn oil deposits. Regular cleaning will help keep your vehicle in optimal condition and prevent future oil ring sticking.

Use a Filter

Using a filter is crucial for maintaining the cleanliness of the oil and preventing the accumulation of dirt and debris that can lead to the oil ring becoming stuck. The filter acts as a barrier, trapping particles and preventing them from circulating in the oil system.

When selecting a filter, choosing one compatible with your vehicle’s make and model is important. Regularly inspect and replace the filter according to the manufacturer’s recommendations to ensure optimal performance.

Change the Filter on a Regular Basis

As a preventative measure, you should regularly change the filter. The filter is crucial in keeping the oil clean and free from contaminants. Over time, the filter accumulates dirt, debris, and other particles that can hinder the smooth operation of the oil ring.

By changing the filter regularly, you ensure that the oil flowing through the engine is filtered properly, minimizing the risk of the oil ring becoming stuck again. According to the manufacturer’s recommendations, filters should be replaced between 3,000 and 10,000 miles, depending on the vehicle and driving conditions.
