Why is my crank seal leaking?
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.
Can oil leak from crankshaft?
Oil leaks. Oil leaks are the most common symptom of a problem with the crankshaft seal. If the crankshaft seal dries out, cracks, or breaks, it can cause an oil leak. Small leaks can cause oil to accumulate on the undersides of the engine, while larger ones may produce a drip of oil from the front of the engine.

It is only logical that if I have eliminated other possibilities like oil lines, grease from swivel tube or excess oil dripping from air intake then it must be from the crank, no?
