Should you use sealant on gaskets?

A general rule, if you are using gasket sealant, you don’t need a lot! Automotive applications commonly use gasket sealant alongside solid gaskets, as they are repairing older parts.

Can I use silicone as gasket sealant?

Can you use RTV sealant instead of gasket?

It is fine to use the correct RTV sealant instead of a gasket if used in the right application (oil, high temp, fuel). Not, however, if the gasket thickness is required to produce a specific amount of clearance. RTV sealant is better than primitive gaskets in most applications ie.
