Subject:What is the wire path for the tach signal?
From:Robert Fisher

This is for the '87 2.1 Auto: Replaced the coil, finally got the van
running again (long story, of course) but now the tach is dead. I read
through the archives and looked at the wiring diagram in the Bentley but
it's not clear to me. I haven't driven the van much since I got it running
but I noticed a "power drop out" or hiccup in the engine that makes me
think of the description several people have given for Vanagon Syndrome,
like a heart skipping a beat. The Hall sensor tested out okay but I'm not
convinced that I don't have another problem other than the coil, or maybe
the same intermittant problem I had before.

Also: I had a leaking valve gasket, so I replaced them both. There was no
standing oil in the starboard head, but there was some in the port head,
which is the one from which it was leaking. It wasn't a lot, but the
differnce made me wonder if I had a problem in one or the other.

I had to replace the rear exhaust pipe due to cracks, and because some
chucklehead PO decided that it'd be a good idea to weld a so-called hitch
to the engine carrier bar I had to drop the whole thing just to replace
that pipe. Turns out I had three broken engine mounts (!) (thought it was
only one) so it had to be done anyway, but I was cussin' fit to make a
sailor blush for a while there.

So I've had a lot of "quality time" with my van lately. : /
