Front crank seal leaking
On my 96 LT4, I noticed light oil on the bottom of the front oil pan and the crank sensor connector is covered with oil. Looks like the crank seal has a small leak. There are no oil drips on the ground. Should I replace the seal now or wait till it gets worse, like when it starts dripping on the floor?

It could be the crank sensor o-ring. The opti-spark and water pump was replaced a few thousand miles ago. I assume the timing cover seals were replaced but not sure.
