According to the Engine Builders Association, a head gasket is a critical component that seals the combustion chamber between the engine block and cylinder head. It prevents the mixing of oil and coolant while maintaining compression.
The underlying reasons for the importance of selecting the right head gasket involve pressures and temperatures that exceed the limits of standard components. Boosted engines, such as those that utilize turbochargers or superchargers, generate more force than naturally aspirated engines. This increased force raises the risk of head gasket failure. If a head gasket fails, it can result in significant engine damage, such as blown seals, coolant loss, and reduced engine efficiency.
Head gaskets are designed to withstand specific operational conditions. For boosted applications, it is essential to use a multi-layer steel (MLS) gasket, as it offers superior sealing capabilities and durability. An MLS gasket consists of multiple layers of steel that compress under clamping pressure, forming a strong seal. Conversely, factory gaskets may not handle higher pressures, leading to potential leaks.
Several conditions can contribute to head gasket failure in boosted B18C1 engines. High cylinder pressure, excessive heat, and improper installation can strain the gasket. For example, if an adapter is used during a turbo installation without proper alignment, uneven pressure may occur. This misalignment can cause the gasket to fail under the high operating conditions of a turbocharged engine.
