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.

  3. The clutch slipping because oil is spraying on the clutch.
  4. Oil leaking from the front crank pulley.
