Frequently Asked Questions (FAQs)
1. Should I use RTV on intake manifold gasket?
RTV should only be used on the corners of the intake manifold gasket and stepped casting areas with a gap. It should not be applied to the entire gasket. Using a small amount of RTV in these specific areas helps ensure a leak-free assembly.
2. Can I use Permatex on intake manifold gaskets?
Yes, Permatex Ultra Gray or Optimum Gray can be used as sealers for intake manifold gaskets. These sealers provide effective sealing when applying the gaskets to the head. Additionally, Edelbrock's Gasgacinch is recommended as a contact adhesive to hold the intake gaskets in place.
3. What kind of gasket do I need for an intake manifold?
For an intake manifold, it is recommended to use high-quality gaskets like Fel-Pro ®. These gaskets are typically constructed as one-piece with reinforced edges and linings around each port or runner opening. They are made from aluminized steel coated in a carbon-based rubber compound, ensuring a reliable seal between the intake manifold and the engine.
4. 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 to ensure compatibility and prevent any potential issues.
5. Can you use Permatex Ultra Black on intake manifold?
Yes, Permatex Ultra Black RTV gasket maker can be used on an intake manifold. Apply the gasket maker, let it set for a couple of minutes, then place the manifold without wiggling it around. Finally, torque it down securely to complete the installation.
6. Does stop leak work for intake manifold gasket?
Bar's Leaks Liquid Copper Block Seal Intake & Radiator Stop Leak is designed to chemically repair leaks in the intake manifold and intake manifold gasket, along with other major cooling system leaks. It is specifically formulated for these types of repairs.
7. Does an intake manifold add horsepower?
A properly designed intake manifold that matches the engine's requirements can increase torque and horsepower compared to a mismatched manifold. The intake manifold plays a crucial role in optimizing the airflow and fuel mixture to the engine's cylinders, resulting in improved performance.
8. Do Fel-Pro gaskets need sealant?
In most cases, Fel-Pro gaskets do not require the use of sealant. However, there may be certain situations where the use of sealant is necessary, such as when mating gaskets or filling gaps. It is recommended to follow the specific instructions provided by Fel-Pro and consult with a professional if needed.
