What causes a crankshaft seal to go bad?
Crankshaft seal leak, in most cases, is caused by high mileage. For every 100,000 miles, the crankshaft seal has to be checked as it is almost, if not at the end of its lifespan. As a car is being driven over a period of time, the crankshaft seal, just like any rubber component, can dry out and become brittle.
When should crankshaft seals be replaced?
Signs your crankshaft seal needs to be replaced include:
- Engine oil leak or oil splattered on your engine.
- Oil spraying on the clutch.
- The clutch slipping because oil is spraying on the clutch.
- Oil leaking from the front crank pulley.
