When my front (between engine and flywheel) crankshaft seal went (was
getting much oil on the hatch) I tried, as a "buy some time" effort,
some oil stopleak treatment.  It's supposed to soften the seal's rubber.
  It didn't work in my case.

By the way, the seal went shortly after switching to synthetic oil.  It
might have been coincidence but I suspect not.

I didn't pull the engine but opted to drop the transmission to replace
the clutch and seals.  I did this in my driveway (hardpack gravel) and I
did it without a transmission jack and without any assistance.

When I pulled the old seal, it was hard as a rock.  Brittle.  It wasn't
at all pliable.  Nothing was going to soften that sucker.

After I put everything back together, I again put in synthetic oil
without any problems.
