When should gasket sealant be used?

• A. Always for every gasket
• B. Before installation
• C. Never
• D. Only as directed

Answer: (D)

The key idea is to follow the gasket sealant instructions provided by the gasket or equipment manufacturer. Sealant isn’t needed for every gasket, and using it when not specified can cause problems like clogging oil passages, contaminating surfaces, or preventing proper seating. When a directive exists, apply sealant only in the areas and amounts specified, and ensure surfaces are clean and dry before installation. Some gaskets are designed to seal on their own and don’t require any sealant, while others need a precise, limited bead of sealant on particular joints or threads. So the correct approach is to use sealant only as directed.
