Having carrying out an oil change at the weekend I have mistakenly over filled the engine with oil which is now dripping from seems to be the crank shaft seal on the gearbox side.

What I need to know is that if it is leaking from the crankshaft seal does it mean that it needs replacing or does it mean that if I remove some of the oil back to the maximum fill level will it cure the problem?

Any help will be appreciated.
