Can I use gasket sealer instead of gasket?

A general rule, if you are using gasket sealant, you don't need a lot! Gasket sealant can be used to make cheaper gasket materials more robust, increasing adhesion and chemical/water resistance. RTV sealants are Room Temperature Vulcanising and needs to be at room temperature to cure.

One may also ask, do I need sealant on a rubber gasket?

However, if valve covers are not likely to be removed, rubber gaskets can be coated on both sides with RTV or other sealants for a long-lasting, leak-free seal. Although valve cover gaskets don't necessarily need sealers or cements, it's a common practice to glue the gasket to the valve cover.

Do I need gasket sealer for thermostat?
