FAQ:

Q: Should I use sealant on my gaskets?

A: It is a widely-held misconception that gaskets need sealant. Manuals for most motorcycle manufacturers specify that sealant is unnecessary , but it can even be harmful. When a silicone-based or other sealant is used, it can interfere with the proper function of the engine.

Q: Do I need gasket sealer?

A: Gaskets are made to expand just a little when oil hits them. This makes a good, oil tight seal. If your sealing surfaces are smooth and you have a new gasket, you simply do not need gasket cement. A real sign of an amateur is lots of slobbery gasket cement.

Q: Can I use high temp RTV instead of a gasket?

A: 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.

Q: Is thermostat gasket reusable?

A: Mr. Gasket’s molded rubber water outlet/thermostat housing gasket is reusable . This gasket is composed of an aluminum carrier with a molded silicone insert to ensure the micro seal of engine coolant. Seals surface irregularities between intake manifold and water outlet/ thermostat housing.
