What You'll Learn
Using Permatex gasket maker on an oil pan
Once the surfaces are prepared, the next step is to apply the Permatex gasket maker. It is recommended to use a non-hardening gasket sealant, such as Permatex Blue, in a thin and consistent bead. Spread the sealant evenly onto the gasket side that mates with the oil pan. It is important not to apply too much sealant to avoid excess squeezing out the sides. Place the gasket, aligning the holes, and then attach the oil pan, tightening the bolts to half torque.
After attaching the oil pan, wipe away any excess sealant. The sealant should be evenly compressed and squeezed without any voids between the oil pan and the gasket. This ensures a proper seal. It is important to allow the sealant to cure completely before using the oil pan. The curing time can vary, so it is essential to follow the manufacturer's instructions for the specific Permatex product being used.
Some users have reported successful experiences using Permatex gasket maker on their oil pans, especially on machined aluminum surfaces. However, it is crucial to follow the instructions and create the right conditions for the sealant to cure properly. Additionally, it is worth noting that removing Permatex or RTV sealants can be challenging, so it may not be the best option if the gasket needs to be replaced frequently.
In conclusion, using Permatex gasket maker on an oil pan can be a suitable alternative to a traditional gasket, but it requires careful preparation, the right conditions, and proper curing time. It is always important to consult the manufacturer's instructions and take the necessary precautions to ensure a successful seal.

Applying RTV silicone to an oil pan
Allow the assembly to sit until the sealant has cured. This can take 12-24 hours, so it is best to leave it overnight. Once it has cured, you can remove the oil pan and gasket assembly as one piece. Apply non-hardening gasket sealant against the remaining gasket face. Re-attach the oil pan/gasket assembly, and torque to the specified value.
It is important to note that the application of RTV silicone to an oil pan is a tricky process, and it is easy to make a mess. Make sure to follow the instructions on the RTV silicone package for bead width, setup time, and any other specific instructions. Additionally, always clean off any old RTV silicone from the pan and block before applying new silicone.
Some people prefer to use a gasket with RTV silicone, while others prefer to use silicone alone. It is recommended to use a very small amount of RTV silicone if using it with a gasket, to ensure that it is easier to keep it even. You can also use FIPG, or a cork gasket with RTV silicone on both sides.

Using cork gasket with oil pan
Gasket makers are used to seal engine components, such as oil pans, and can be made from a variety of materials, including cork. Cork gaskets have been used in industrial gasketing for decades and are known for their sealing capabilities and versatility across industries. They are made from the bark of Cork Oak trees, which can be sustainably harvested every 9-12 years without harming the tree.
When using a cork gasket with an oil pan, it is important to follow certain steps to ensure a proper seal and avoid leaks. Firstly, clean the oil pan thoroughly with a degreaser or brake cleaner to remove any dirt, grease, or oil residue. This is crucial as it ensures that the gasket adheres properly to the pan.
After cleaning, some sources suggest applying a thin coat of RTV (Room Temperature Vulcanizing) silicone gasket maker to the gasket. RTV silicone comes in various colours, including black, blue, grey, and red, and can be applied to both sides of the gasket or just the side that mates with the oil pan. It is important not to use excessive sealant, as you don't want it to squeeze out the sides. You can also use other types of sealants like Indian Head gasket cement or plain old silicone tub caulk.
Once the sealant is applied, place the gasket onto the oil pan, aligning the holes, and attach the oil pan but leave the bolts finger-tightened, allowing the sealant to cure. After curing, tighten the bolts to the specified torque value. This process helps create a strong seal between the gasket and the oil pan.
It is worth noting that cork gaskets may start to fall apart and leak after a few years, so regular maintenance and inspections are important. Additionally, when replacing a cork gasket, be careful not to stretch it, as this can ruin the gasket and require a replacement.

Using rubber gasket with oil pan
When it comes to oil pan gaskets, there are a variety of options available, including cork, rubber, and copper gaskets. Some gaskets come with a silicone bead already attached, while others require the separate application of a sealant. The use of a sealant or gasket maker with an oil pan gasket is a common topic of discussion, with varying recommendations.
Some people recommend using a sealer with the gasket on pans due to irregularities in stamped metal pans. RTV silicone gasket makers, available in colours like red, blue, grey, and black, are commonly suggested for use with oil pans. It is recommended to apply the sealant to the pan first, followed by the gasket, and then add more sealer to the block to avoid mess. This method helps to prevent the sealant from getting onto the wrong places.
It is important to note that the application of silicone should be minimal, and the surfaces should be clean and free of oil and debris to ensure an effective seal. Some people also use gasket cement or other types of sealants like Permatex High Tack or GM engine sealant. It is recommended to consult the instructions provided with the gasket and seek advice from auto part store professionals to determine the most suitable approach.
When using a rubber gasket with an oil pan, it is essential to follow similar steps as mentioned above. Clean the surface of the oil pan thoroughly and ensure that the mating face of the block/head is also clean and degreased. Apply a layer of permanent sealant, such as Permatex, silicone, or a gasket maker product, to the side of the rubber gasket that will mate with the oil pan. Ensure that the sealant is evenly distributed and not excessive.
Place the rubber gasket onto the oil pan, aligning the holes correctly. Attach the oil pan but avoid tightening the bolts completely; half torque is sufficient. Wipe away any excess sealant, ensuring that it is evenly compressed and squeezed without any voids between the oil pan and the gasket. Allow the assembly to sit until the sealant has cured. Once cured, the oil pan and gasket assembly can be removed and reassembled without the need for a new gasket each time.
