While valve cover gaskets may not always require a sealant or cement, it is a common practice to use one to help secure the gasket to the valve cover and ensure a good seal. Based on the reference provided, there isn't a single product identified as the absolute best, but several options are noted as working well for this application.
Recommended Sealants for Valve Cover Gaskets
According to the information provided, the following types of sealants "work well" for valve cover gaskets:
- Permatex No. 1
- RTVs (Room Temperature Vulcanizing sealants)
- Permatex High Tack gasket sealant
These products are suitable choices for sealing valve cover gaskets, whether you are opting to glue the gasket to the cover before installation or applying a thin bead in specific areas as recommended by some manufacturers.
Why Use a Sealant?
Even though not strictly necessary in all cases, using a sealant can offer benefits:
- Gasket Retention: It helps hold the gasket in place on the valve cover during installation, making the job easier.
- Improved Sealing: It can fill minor imperfections on the mating surfaces, enhancing the leak prevention capability, especially in areas prone to leaks like corners or around bolt holes.
Choosing one of the sealants that are known to "work well" for this purpose, such as Permatex No. 1, RTVs, or Permatex High Tack gasket sealant, can contribute to a successful, leak-free valve cover installation.
Remember to always clean the mating surfaces thoroughly before applying any sealant or installing the gasket. Consult your vehicle's service manual or the sealant manufacturer's instructions for specific recommendations on application techniques and curing times.
