The Engine Timing Chain Cover/Sealing Plate is a crucial component located at the rear of the engine, designed to protect the timing chain and maintain optimal engine performance. This factory-original part ensures a seal between the engine block and the timing chain assembly, preventing oil leaks and contamination. Common signs for replacement include oil leaks, debris buildup, or wear that compromises engine efficiency. It interconnects with the engine's timing system, ensuring precise synchronization of engine components. This cover is compatible with several Audi and Volkswagen models, with OEM part numbers 06E103171J, 06E103171F, 06E103171G, and 06E103171C.
Replacement is necessary if the sealing plate displays visible damage or signs of wear, as neglect can lead to significant engine problems. It may also be referred to as the timing chain cover in various contexts.
