The AMC 360 engine is a V8 engine produced by American Motors Corporation, which has also been used in some Jeep models. Installing an intake manifold gasket with a valley pan in the AMC 360 engine is a straightforward process. The valley pan gasket replaces the individual side-only style intake manifold gasket and includes a pan that connects the left and right sides. This prevents excess oil from splashing onto the intake manifold baffle, reducing oil consumption and keeping the incoming air cooler. Before installation, it is recommended to mock up the intake manifold to ensure bolt hole alignment. Additionally, while some installers use a paper gasket on top of the valley pan gasket, it is important to note that the valley pan gasket cannot be reused once it has been torqued down, as it will not seal properly and may cause oil and coolant leaks.

What You'll Learn
Use a valley pan gasket or an intake manifold gasket
The use of a valley pan gasket or an intake manifold gasket depends on the specific application and requirements. Here is some detailed information regarding their usage:
Valley Pan Gasket:
- The valley pan gasket is specifically designed for the AMC 360 engine and is an integral part of the valley pan intake system.
- Its primary purpose is to prevent oil from getting baked and burned by the exhaust passage, thus protecting the oil from excessive heat.
- Some intake manifold manufacturers, such as Weiand Stealth, advise against using a valley pan intake gasket.
- If your intake manifold or cylinder heads do not possess an exhaust crossover passage, a valley pan gasket is typically not required.
- Reusing a valley pan gasket is not recommended, as it can lead to oil and coolant leaks.
Intake Manifold Gasket:
- The intake manifold gasket is a critical seal between the intake manifold and the engine block or cylinder head.
- It ensures proper compression and prevents leaks in the intake tract.
- Intake manifold gaskets are available in various materials, such as paper, metal, or high-temp RTV silicone.
- When using a metal gasket, it is essential to mock-up the installation to ensure proper alignment of bolt holes and sealing surfaces.
- Some engines, like the Air Gap manifold, have intake runners completely sealed off from hot engine oil, eliminating the need for a valley pan gasket.
The decision to use a valley pan gasket or an intake manifold gasket depends on the engine's design, the presence of an exhaust crossover passage, and the specific recommendations of the manufacturer. It is essential to refer to the correct service manual and follow the advised procedures for your particular engine.

Mock-up to ensure bolt holes align
When installing an AMC 360 valley pan, it is important to ensure that the intake manifold bolt holes align properly. This process is known as "mock-up" and is a crucial step before sealing the intake to the heads and engine.
To begin the mock-up process, gently set the gasket in place, lining up one corner hole at a time. Screw in one corner intake bolt to hold the gasket in position, and then repeat this process for the remaining three corners. Once all four corners are secured, gently tighten the nuts to press and hold the gasket in place. It is recommended to let this setup sit overnight to ensure that the gasket is firmly held in position.
The next step is to remove the bolts, discard the nuts and washers, and apply black RTV to the manifold side of the intake gasket. It is important to use rubber gaskets for the end pieces, applying RTV to the rubber end pieces as well. Set the intake manifold in place and carefully install the intake bolts, torquing them with care.
It is worth noting that some installers may choose to use a paper gasket on top of the valley pan gasket. Additionally, ensuring proper alignment during the mock-up process can be challenging, and it is recommended to spend a significant amount of time forming the valley pan to achieve a perfect fit. The valley pan should sit as closely as possible without being banged with the intake.

Don't reuse the valley pan gasket
When installing an AMC 360 valley pan, it is important to remember not to reuse the valley pan gasket. This is because the gasket is not a metal plate but rather a soft, flexible gasket that will deform and lose its integrity if reused.
The purpose of the valley pan gasket is to provide a precise seal for the engine, ensuring maximum horsepower and optimum flow and performance. Reusing the gasket will compromise this seal, leading to oil and coolant leaks. Oil splashing on the intake manifold will cause the engine to burn extra oil, affecting performance and potentially causing damage.
Some installers may choose to use a paper gasket on top of the valley pan gasket, but this is not a substitute for a new valley pan gasket. The paper gasket is used as an additional precaution to prevent oil leaks, but it cannot compensate for a reused valley pan gasket.
It is worth noting that AMC only uses the Valley Pan Intake Gasket, and it is essential to ensure that the intake manifold bolt holes align correctly before sealing the intake to the heads and engine. This step is crucial to ensure a proper seal and prevent leaks. Therefore, it is highly recommended to use a new valley pan gasket with each installation to maintain the integrity of the seal and prevent potential issues and damage to your engine.

Use RTV at the front and back
When installing an AMC 360 valley pan, using an RTV sealant is a common practice to ensure a secure and leak-proof fit. RTV, or room-temperature vulcanizing rubber, is a type of silicone sealant that cures into a strong, flexible rubber. It is an effective adhesive and sealant for automotive applications due to its durability and resistance to high temperatures and vibrations.
In the context of installing an AMC 360 valley pan, RTV is specifically used at the front and back of the pan to create a tight seal between the pan and the engine block. This helps prevent leaks and ensures the pan remains securely in place. Here are some detailed instructions and tips for using RTV at the front and back when installing the AMC 360 valley pan:
- Preparation: Before applying RTV, ensure that the mating surfaces of the valley pan and the engine block are clean, dry, and free of debris. It is important to follow the manufacturer's instructions for surface preparation, as this will impact the effectiveness of the seal.
- Application Technique: Apply a heavy bead of RTV along the front and rear mating surfaces of the valley pan. Use a continuous and generous amount of RTV to ensure a thorough seal. Some installers recommend using black RTV for this purpose, as it is designed for high-temperature environments and provides a strong bond.
- Locating the Pan: The RTV will act as a temporary adhesive to hold the valley pan in place while you position it correctly. The AMC 360 valley pan typically has locating holes or ridges at the front and rear that align with the engine block to keep the pan in place. Ensure that these locators are properly inserted into the corresponding holes in the block.
- Cure Time: Allow the RTV adequate time to cure and form a strong seal. Depending on the RTV product used, the recommended cure time can vary, but it is generally recommended to let the RTV set for at least 24 hours before starting the engine. This ensures that the sealant has fully cured and can withstand the stresses of engine operation.
- Bolts and Gaskets: In addition to RTV, some installers recommend applying RTV to the threads of corner bolts and using it in conjunction with gaskets. For example, you can use copper-colored RTV for specific ports and black RTV for other ports and bolts. This provides an extra layer of sealing and security, ensuring that the valley pan is properly secured.
- Oil Baffle Plate: Consider using an oil baffle plate at the bottom of your intake manifold. The oil pan valley may come into contact with the baffle plate, so trimming the plate for proper clearance may be necessary.
By following these instructions and tips, you can effectively use RTV at the front and back when installing an AMC 360 valley pan, ensuring a secure and leak-proof installation.

Use a paper gasket on top of the valley pan gasket
When installing an AMC 360 valley pan, there are several methods you can use to ensure a proper seal. One option is to use a paper gasket on top of the valley pan gasket. This method has been utilised by some mechanics and car enthusiasts, who have shared their experiences online.
One individual shared their process for sealing a valley pan using paper gaskets. They planned to use the Felpro 1214 valley pan, which comes with four paper gaskets. Their process included tacking both gaskets to the valley pan, with one on the intake side and the other on the head side. They then proposed spraying the gaskets with Permatex copper sealant, applying black RTV in the corners and on the china wall, and using Permatex thread sealant on the intake bolts. However, they were concerned about bolt alignment and considered testing the fit before applying adhesive.
Another individual shared a similar experience, emphasising the importance of testing the fit first. They did not use the extra paper gaskets with the metal pan and instead applied RTV where necessary. They allowed it to sit overnight and reported no oil leaks after a brief initial run. They also mentioned that some people use paper gaskets when reusing the bathtub gasket or with aluminium intake and cast iron heads.
It is worth noting that opinions vary on the use of paper gaskets with valley pans. Some people have successfully sealed their valley pans without using paper gaskets, relying solely on the valley pan itself or using other methods like RTV or sealant. Ultimately, the decision to use paper gaskets on top of the valley pan gasket is up to the installer, and there may be multiple effective methods to achieve a proper seal.
