How to Identify and Fix a Front Crank Seal Leak
A front crank seal leak is a common problem in vehicles, particularly those with high mileage. It occurs when the front crank seal, which seals the crankshaft to the engine block, breaks down and begins to allow oil to escape. This can result in a loss of engine oil, and can potentially cause damage to other components if not repaired quickly. Symptoms of a front crank seal leak include leaking oil from around the crankshaft area, low engine oil levels, and smoke or burning smells coming from the engine. If you suspect your vehicle has a front crank seal leak, it’s important to have it inspected and repaired as soon as possible by a qualified mechanic.
