Cleaning the surface and applying sealant
When installing a 340 Mopar oil pan gasket, cleaning the surface and applying sealant is a crucial step to ensure a durable seal and prevent leaks. Here is a detailed guide on how to approach this step:
Cleaning the Surface:
Before applying any sealant, it is essential to clean the mating surfaces of the oil pan, gasket, and engine block thoroughly. Use a suitable cleaner, such as brake parts cleaner, to wipe down the surfaces with fresh paper towels until they are free of oil, grease, and debris. Pay particular attention to the areas where the gasket and seals meet, as these areas need to be clean and dry for the sealant to adhere properly.
Applying Sealant:
Once the surfaces are clean, you can begin applying the sealant. It is recommended to use a high-quality sealant designed for automotive use, such as RTV silicone gasket maker or Permatex High Tack. Spread the sealant evenly into a thin coat on the pan side of the gasket, ensuring that it covers all mating surfaces. A thin film of sealant is generally sufficient, and you should avoid applying too much to prevent it from squeezing out when the gasket is tightened.
Small dabs of sealant in the corners and where the gasket and seals meet are crucial to creating a durable seal. Pay close attention to the areas where different materials meet, such as where the rubber meets the cork. You can use RTV or a suitable adhesive in these areas to ensure a tight seal and prevent leaks.
It is important not to overtighten the bolts, as this can cause the gasket to push out or the sealant to squeeze out excessively. Follow the torque specifications provided by the manufacturer for best results.
Drying and Curing:
After applying the gasket and sealant, allow the assembly to sit until the sealant has dried and cured completely. This step is crucial, as it ensures that the sealant forms a strong bond and can withstand the pressures and temperatures it will be subjected to. Refer to the sealant manufacturer's instructions for the recommended curing time.
By following these steps for cleaning the surface and applying sealant, you can effectively install a 340 Mopar oil pan gasket, creating a secure seal that prevents leaks and ensures the optimal performance of your engine.

Using cork or black fibre
When installing a 340 Mopar oil pan gasket, there are a few different methods you can use, depending on your preference. Some people prefer to use a one-piece gasket made from materials such as rubber, while others opt for a four-piece design using paper or composite. If you're using cork or black fibre, here are some detailed instructions to follow:
First, lay the oil pan on a flat surface and check the mating flanges and bolt holes. It is important to ensure that the pan rails are flat and even, as any warping can cause issues with sealing. Use a ball pien to dimple the bolt holes outward slightly, towards the bolt head. This will help ensure that the gasket is tight between the bolts and evenly sealed all around.
When using cork or black fibre gaskets, it is crucial to clean the surfaces thoroughly. Use a cleaner like Brake Parts Cleaner and fresh paper towels to wipe down both surfaces until they are completely free of oil and grease. Even the oil from your skin can cause issues, so be meticulous in this step.
Once the surfaces are clean, apply a thin layer of RTV sealer or a similar product to the pan side only. Let it set for a few minutes before laying the gasket down. Be careful not to over-tighten the bolts, as this can cause the gasket to squish out. Small dabs of sealer in the corners are also necessary to prevent leaks.
Some people prefer to use a combination of RTV and weatherstrip adhesive to secure the cork or black fibre gaskets. Apply a thin film of RTV to the cork, leaving it slightly sticky, and then use small dabs of weatherstrip adhesive to hold the gasket in place. This two-step process can provide a more secure seal and prevent leaks.
When tightening the bolts, start from the centre and work your way outward. Gently tighten each bolt until you see some of the gasket material spread near the bolt, then move on to the next one. Finally, go back and give each bolt one more gentle turn to ensure everything is secure.
By following these steps and paying attention to the details, you can successfully install a 340 Mopar oil pan gasket using cork or black fibre and create a tight seal to prevent leaks.

Using a one-piece or four-piece gasket
When installing a 340 Mopar oil pan gasket, you can use either a one-piece or four-piece gasket. The one-piece gasket is made by Speciality Component Engineering (SCE) and is called the SCE AccuSeal Pro Oil Pan Gasket. It is available from Summitracing for $27.95.
Some people prefer the one-piece gasket because it is seen as easier to install and there are no issues with the gasket "walking out" or squishing out. To install this type of gasket, you should put some RTV in the corners where the rubber meets the cork. You can also use small dabs of 3M super weather strip adhesive to hold the cork into position and let it set up before installing.
However, others prefer the four-piece gasket because it allows for a better seal. To install this type of gasket, you should wipe both surfaces down with Brake Parts Cleaner and fresh paper towels until they are oil-free. Then, apply a thin film of RTV sealer to the pan side only and lay the gasket down, letting it set for a few minutes. It is important not to over-tighten the bolts, as this can cause the gasket to "squish out". Small dabs of sealer in the corners are also needed to prevent leaks.
Some people choose to use a combination of both types of gaskets, cutting the one-piece gasket to match the old-style side pieces and using the old-style end pieces with a dab of RTV in the corners. This can provide a good seal without crush issues.

Torque values and tightening bolts
Firstly, it is important to start with clean and dry surfaces. Ensure that the oil pan rails are flat and free of any warping or deformities. Use a rubber mallet to flatten the rails if necessary. It is also recommended to clean the cork surfaces with a suitable cleaner, such as Brake Parts Cleaner, and fresh paper towels to remove any oil residue.
When applying sealant or adhesive, it is generally advised to use a thin film of RTV sealer or another suitable product on the pan side only, allowing it to set for a few minutes before placing the gasket. Small dabs of sealer in the corners can help prevent leaks. Avoid over-tightening the bolts, as this can cause the gasket to squish out.
The sequence of tightening the bolts is important to ensure an even seal. Start by tightening the bolts in the middle, and then work outwards in a criss-cross or star pattern. This helps distribute the pressure evenly across the pan and gasket. Repeat this process a few times, gradually increasing the torque with each pass. For the final pass, refer to the manufacturer's specifications for the recommended torque value, which is typically around 9 ft-lbs for LS machines.
It is also recommended to retighten the bolts after a certain period, such as the next day, to ensure that the gasket remains securely in place and to prevent any potential leaks. This process may vary depending on the specific vehicle and gasket type, so always refer to the appropriate service manual or seek advice from experienced mechanics or online forums.
Additionally, some mechanics recommend tightening to just before they break or using a “tight is good” approach, suggesting that overtightening can be just as detrimental as under-tightening. Finding the right balance is crucial to ensure a successful installation.

Removing the oil pan
Firstly, it is important to address the oil leak. Clean the surfaces with a suitable cleaner, such as Brake Parts Cleaner, and fresh paper towels until they are free of oil. This will ensure that the new gasket forms a tight seal.
Next, you will need to remove the oil filter adapter by unscrewing the centre bolt. The oil pan can then be carefully removed. One user reported that they had to also remove the starter motor, the centre link, and the right motor mount to access the oil pan. It is important to be cautious when removing the oil pan to avoid damaging the crank and K-frame.
Once the oil pan is removed, inspect it for any signs of damage or warping. The pan rails should be flat, and any warping can be corrected by gently tapping them with a rubber mallet on a concrete floor.
Finally, before installing the new gasket, it is recommended to apply a sealant. A thin film of RTV sealer can be applied to the pan side of the gasket, and small dabs of sealer can be added to the corners to prevent leaks.
