Frequently Asked Questions (FAQs)
1. What material is best for exhaust manifold gasket?
Copper is the best material for an exhaust manifold gasket due to its superior thermal conductivity. It helps stabilize head and block temperatures and can withstand the high heat generated by the exhaust system.
2. Should I use RTV on exhaust manifold gasket?
RTV should not be used on the entire gasket. It should only be applied to the corners and stepped casting areas with gaps. Using a small amount of RTV in these areas helps ensure a leak-free assembly.
3. Should I use Permatex on an exhaust manifold gasket?
Permatex, a chemical gasket maker, can be used as a replacement for pre-cut gaskets. It is particularly suitable for high-temperature applications such as the exhaust manifold, header, turbochargers, and slip-fit exhaust parts.
4. Do exhaust gaskets make a difference?
Yes, faulty exhaust manifold gaskets can negatively impact a car's performance and efficiency. Leaking gases can result in a noticeable loss of power and acceleration. While it won't cause sudden breakdown, it is important to get it fixed to maintain optimal engine performance.
5. What is the difference between MLS and graphite exhaust manifold gasket?
Graphite gaskets are often less expensive than MLS (multi-layer steel) gaskets. Graphite gaskets are more forgiving and can seal on rougher surfaces due to their compressibility. MLS gaskets, on the other hand, provide a higher level of sealing performance and are more suitable for certain engine configurations.
6. When should you not use RTV sealant?
RTV sealant should not be used in applications that will have direct exposure to gasoline, such as powersports vehicles. In such cases, a solvent-based gasket maker should be used.
7. How long does it take for Permatex exhaust sealer to dry?
Permatex exhaust sealer typically dries in about 30 minutes. However, it is recommended to let it fully cure without getting wet beyond application for 24 hours to ensure a strong and durable seal.
8. Are thicker exhaust gaskets better?
In general, using the thinnest gasket possible is the best option as it minimizes compressibility while providing better load retention and recovery properties. However, there may be situations where thicker gaskets are needed to compensate for specific factors in the exhaust system.
