Changing Oil Pan Gasket In 1995 Acura Integra

If you're looking to change the oil pan gasket on a 1995 Acura Integra, there are a few steps you'll need to follow. First, drain the oil and remove the oil pan by taking out the bolts. Remove the old gasket and clean the surface, then put on the new gasket, ensuring it's seated properly. Replace the bolts and tighten them evenly—using a torque wrench is recommended. You'll also need to remove the header/exhaust manifold to access the oil pan bolts. It's important to verify that the oil pan gasket is leaking, as it may be collecting oil from a different leak. Make sure to check for any damage to the oil pan as well, as road debris can cause issues.

Remove the oil pan by taking out the bolts

To remove the oil pan, start by draining the oil. Then, remove the 10mm bolts and take out the oil pan. You may need to use a wrench to loosen the bolts, but be careful not to overtighten them as this can cause damage.

Once the bolts are removed, take out the old gasket and clean the surface, ensuring it is free of any residue or leftover gasket material. It is important to make sure the surface is clean and dry before installing the new gasket. You may want to use a wire brush or a gasket scraper to ensure the surface is thoroughly cleaned.

Before installing the new gasket, check that it is properly seated and consider applying a thin layer of oil to help it set easily. When putting the new gasket in place, be sure to follow the correct torque sequence and torque the bolts to the specified tightness—9 lbf/ft or 109in. lbs. per bolt for Acura Integra.

Finally, reinstall the oil pan and tighten the bolts securely, but not too tightly, to avoid any leaks.

Remove the old gasket and clean the surface

To remove the old oil pan gasket and clean the surface of your 1995 Acura Integra, you'll need to follow a few important steps to ensure a successful repair. Here's a detailed guide to walk you through the process:

Removing the Old Gasket:

• Gather the necessary tools and materials, including plastic or composite scrapers, rags or paper towels, and a suitable detergent or solvent. Avoid using metal tools to prevent damaging the soft aluminum engine surface.
• Start by locating the oil pan and its gasket. The oil pan is attached to the bottom of the engine and can be accessed from under the car.
• Using the plastic or composite scraper, carefully remove the old gasket. Take your time with this step, as it can be slow going. Hold the scraper at a steep angle, chip away at the gasket, or use a combination of these techniques to remove it in small bits.
• Pay close attention to the surface of the aluminum to avoid causing any nicks or gouges. The surface must be smooth for the new gasket to seal properly.
• If needed, use a gasket remover solution to eliminate any remaining residue.

Cleaning the Surface:

• Once the old gasket is removed, it's time to clean the surface thoroughly. This step is crucial for ensuring a proper seal with the new gasket.
• Spray the cleaning solution or solvent onto the surface, making sure to cover all areas where the gasket will sit.
• Use rags or paper towels to wipe down the surface. You may need to scrub gently to remove any stubborn residue or grease.
• For tight or hard-to-reach areas, consider using brake cleaner to ensure a thorough cleaning.
• Inspect the surface to ensure it is free of any residue or debris. It's important to have a clean and smooth surface before installing the new gasket.

By carefully removing the old gasket and cleaning the surface, you'll help ensure a successful repair and prevent future oil leaks. Take your time and work meticulously to achieve the best results.

Put the new gasket on, ensuring it is seated properly

Once the old gasket has been removed, it's time to install the new one. Ensure that the mating surfaces are clean and dry. You can use a wire brush to clean the block and oil pan. It is also recommended to degrease the entire oil pan.

Now, take the new gasket and place it on the oil pan, making sure it is seated properly. You can dip your finger in some oil and rub it on the new gasket so it sets easily.

For an OEM gasket, you can put some Honda bond in the four corners as illustrated in the manual. Alternatively, you can use a thin layer of Honda bond under and on top of the gasket. This will ensure that the gasket does not shift and cause a leak.

Finally, reinstall the oil pan and tighten the bolts. It is recommended to use a torque wrench to tighten the bolts to the specified torque value. For Acura Integra, the torque value is 8.7-9 lbf-ft. Tighten the bolts evenly and in the correct order as specified in the manual.

Replace bolts and tighten evenly

When replacing the oil pan gasket bolts, it is important to tighten them evenly to ensure the integrity of the joint. This can be done by applying torque, or rotational force, to the bolts. Torque wrenches are the best tool for this job as they allow you to apply a specific amount of torque.

To start, select a torque wrench that fits the size of your bolts. You should also have some lubricant or anti-seize compound to hand to reduce friction and prevent galling. Clean the threads of the bolt and nut to ensure correct torque application and to avoid cross-threading. Then, tighten the bolt and nut by hand until they are snug against the surface. This will align the threads and prevent binding when you apply torque.

Next, torque the torque wrench to the specified setting. The correct torque value will be in the equipment's manual or engineering specifications. Connect the torque wrench to the suitable socket and place the socket over the head of the bolt. Apply constant, uniform pressure on the torque wrench until you hear it “click” or the set torque is attained.

If you are tightening multiple bolts, it is recommended that you do so in increments of the recommended torque value, alternating between bolts. This will help you achieve an equal clamping force over the joint.

It is important to avoid over-tightening the bolts as this can cause stripped threads, bolt breakage, and damage to the connected components. Once the torque wrench indicates that the desired torque value has been obtained, stop applying force.

Use Honda bond on the corners

When replacing the oil pan gasket on a 1995 Acura Integra, it is important to use a high-quality sealant, such as HondaBond, to ensure a proper seal and prevent future leaks. HondaBond is a high-temperature silicone gasket maker developed for use in Honda's racing teams and is designed for areas that do not require a solid gasket, such as cylinder head covers. It can be used on oil pans, transmission pans, and valve covers to create a strong, flexible seal that resists oil, water, and most chemicals.

To use HondaBond on the corners of your oil pan gasket, follow these steps:

• Clean and dry the surfaces: Before applying any sealant, ensure that the mating surfaces of the oil pan and engine block are clean, dry, and free of any old residue. This is crucial for the sealant to adhere properly.
• Apply HondaBond: Cut the tip of the tube and squeeze out the sealant generously onto the corners of the gasket. Spread it evenly with a brush or your finger, ensuring complete coverage.
• Allow initial drying: HondaBond sets quickly, usually within 10 minutes. However, it is recommended to let it sit for at least an hour before proceeding to give it time to become tacky and start curing.
• Reassemble the oil pan: After the initial drying period, carefully reinstall the oil pan, ensuring proper alignment and following the correct torque sequence and specifications for your Integra.
• Let the car sit: Ideally, you should let the car sit for at least 24 hours to allow the HondaBond to cure fully. Some people even recommend waiting for up to three days, especially if the temperature is cold, as it takes longer for the sealant to cure completely.
• Add oil and test: After the curing period, add new engine oil and start the engine. Let it run for a while to reach operating temperature, then check for any oil leaks. If there are no leaks, you're good to go!

Remember, when working with HondaBond or any other sealant, always wear gloves and protect your clothing, as it can be extremely messy and difficult to remove once it dries. Also, ensure you follow the instructions on the product label and in your vehicle's repair manual for the best results.
