What do you use to coat the turbine to the exhaust gasket?

Using a high-temperature anti-seize compound is ideal for coating the turbine to the exhaust gasket due to its ability to withstand extreme temperatures and prevent seizing of the metal components. In high-performance applications, the turbine and exhaust system can reach significant temperatures, and this compound not only provides lubrication during assembly but also helps to ensure that the components can be disassembled in the future without damage.

Anti-seize compounds are specifically formulated to conduct thermal energy while protecting metals from oxidizing and corroding under heat. They typically contain a combination of metallic particles and a high-temperature base, making them suitable for use in environments where traditional greases and lubricants would break down or fail. Thus, this choice secures a tight seal in the exhaust system while allowing for safe future maintenance.

Other substances such as standard grease or silicone sealant do not possess the necessary properties to endure the high temperatures and pressures found in exhaust systems, which could lead to failure at the connection point. Thread lockers are used primarily for securing threaded fasteners and are not formulated for the high-temperature conditions and exhaust environments, making them unsuitable for this application.
