What compound is recommended for coating the exhaust gasket to the turbine?

The recommended compound for coating the exhaust gasket to the turbine is a high-temperature anti-seize compound. This is because exhaust systems operate under extreme temperatures, and a high-temperature anti-seize compound is specifically designed to withstand these conditions without breaking down or losing effectiveness. It also helps to prevent seizing or galling of metal parts, which can occur due to the high heat and pressure present in exhaust systems.

Using a high-temperature anti-seize compound ensures that the gasket remains sealed and functional, allowing for proper exhaust flow without leaks. This compound remains stable in high temperatures, which is critical in maintaining the integrity of the connection over time.

In contrast, metallic grease or silicone sealant may not withstand the high heat of the exhaust environment effectively. Regular oil would not provide the necessary heat resistance or sealing capabilities needed for an exhaust gasket. Therefore, the high-temperature anti-seize compound is the most suitable choice for this application.
