The crankshaft seal, commonly known as the main seal, is essential for preventing oil leaks where the crankshaft passes through the engine block. Located at the rear of the engine, this seal creates a secure barrier between the moving crankshaft and stationary engine parts, ensuring oil remains within the engine.
By maintaining proper oil pressure, the crankshaft seal helps lubricate critical internal components, promoting smooth engine performance and reducing the risk of damage caused by oil loss. Replacing a worn or leaking crankshaft seal is crucial to safeguarding your engine's reliability and longevity.
