The crankshaft seal is a critical component in your engine, responsible for maintaining a seal around the rotating crankshaft. Its primary function is to prevent lubricating oil from escaping the engine block and to keep contaminants from entering the crankcase. A failing crankshaft seal can lead to significant oil loss, potentially causing engine damage due to insufficient lubrication. It can also result in oil leaks that may drip onto exhaust components, creating a fire hazard.
