Role in Engine Systems

The 3759618 Oil Seal Plate is essential for maintaining the integrity and efficiency of various engine systems. It is specifically designed to prevent oil leaks and ensure proper lubrication within the engine’s moving parts.

Integration with Turbocharger Systems

In turbocharger systems, such as the aftermarket turbocharger, Heat60 Turbocharger, and HC3 Turbocharger, the Oil Seal Plate plays a significant role. It seals the oil passages within the turbocharger housing, preventing oil from escaping and contaminating the air flow. This ensures efficient turbocharger operation without the risk of oil fouling, which can degrade performance and lead to increased wear on turbocharger components ².

Application in Cam Follower Housing and Camshaft Systems

When integrated into the cam follower housing and camshaft systems, including the camshaft right bank, the Oil Seal Plate helps maintain a consistent oil film on the camshaft and cam followers. This lubrication is vital for reducing friction and wear, thereby enhancing the longevity and performance of these components. The seal plate ensures that oil is directed precisely where needed, without leakage, which is particularly important in high-performance engines where precision and reliability are paramount ¹.

Role in Core Assembly and Supercore Systems

In core assemblies, such as the Core Assembly HT3B (DCM) and Supercore, the Oil Seal Plate is used to maintain the integrity of the oil system within the core. It prevents oil from seeping into areas where it could cause damage or reduce efficiency. This is especially important in high-stress environments where the core assembly is subjected to extreme temperatures and pressures ³.

Importance in Injector Plumbing and EBM-Injector Systems

For injector plumbing and EBM-Injector systems, the Oil Seal Plate ensures that the oil supply to the injectors remains clean and uncontaminated. This is crucial for the precise operation of the injectors, as any oil leakage could lead to inconsistent fuel delivery and compromised engine performance. The seal plate helps in maintaining the correct oil pressure and flow, which is essential for the optimal functioning of EBM-Performance Parts and EBM: Performance Parts ¹.

Use in Engine Brake Control and Turbocharger Mounting

In engine brake control systems and turbocharger mounting configurations, the Oil Seal Plate is employed to prevent oil from escaping around the mounting points and affecting the brake control mechanisms. This ensures that the engine brake operates smoothly and reliably, without the interference of oil leaks. Similarly, in turbocharger and mounting setups, the seal plate helps in maintaining the structural integrity and performance of the turbocharger by ensuring that oil does not seep into the mounting areas ².

Application in Turbocharger Conversion Kit and Parts Kit

In turbocharger conversion kits and turbocharger parts kits, the Oil Seal Plate is a key component that ensures the new or upgraded turbocharger integrates seamlessly with the existing oil system.
