Upshift light failure-->vacuum leak

The upshift light died on my '84 4000SQ a few months ago.  I had
attributed it to a burned out bulb and didn't miss it in the least.
But the recent thread here got me to thinking about vacuum leaks.  A
bit of troubleshooting this weekend (mainly sucking on hoses) led me
to a broken vacuum advance on my distributor.  I guess that the moral
of the story is that not all vacuum leaks can be bad hoses.

Curiously, the only other car I had that developed a leaking vacuum
advance was my old BMW 2002.  Does Bosch have a problem with these
