“Hey man, my car has been making a rumbling noise lately and even shaking sometimes. Someone told me it might be a faulty crankshaft seal. Is that right?” My friend, a car novice, asked worriedly when we met. Indeed, the crankshaft seal, though small, plays an extremely important role, like the “soul” of a car engine. If the “soul” has a problem, no car can run smoothly!

What is a Car Crankshaft Seal?

Simply put, a car crankshaft seal is like a “silent hero,” hidden inside the engine and tasked with preventing engine oil from leaking out. It works by creating a tight seal between the moving and stationary parts of the engine. This ensures that engine oil is always kept within the engine, effectively lubricating the engine components, thereby helping the engine run smoothly and reliably.
