exhaust problem revisited

[Bob Benner]

Here's the page to see what I eventually did to fix the problem.

http://bennersfarm.com/BF%20Home/Bluebir...lemma.html

None of the parts were available so I had to follow the guru Rube Goldberg and
concoct a
fix as I'm leaving Wednesday for the north.

On the page at the top is a picture of what I believe is the tach sender. It is
loose, not
being held by anything and is easily slipped out of its hole. Attached at the
bottom of the
unit is a gear that is also loose and easily lifted from the hole.

Do any of you know if this is a Detroit part or aftermarket or where I can find
it. Also are
there any 'do not's', I should know about when I go to change it?

Looks like that should work...

Apparently the ring slides on the pipe?

None of the flanges are removable on my exhaust pipes. I don't see
how that would have ever held?

my connections consisted of the following:

1.)cast iron exhaust manifold to steel exhaust pipe connected via
a "V" clamp with no removable flange or ring.

2.)steel exhaust pipe connected to cast iron turbo inlet "T" via
a "V" clamp with no removable flange or ring.

Both ends of the steel pipe are flanged to accomodate the "V" clamp.
Both cast iron pieces have a nice flange cast into them.

So, I don't understand the removable flange or ring. It would appear
to me that there has been a repair that was done using none standard
parts.

Looks like what you've done is a very good temporary repair, may
even last a long time ;~}

IS THIS CONNECTION AFTER THE TURBO?

When you said that you noticed more and more black smoke, that would
indicate that the turbo was not forcing a good volume of air into
the engine, therefore the extremely rich mixture(black smoke). Black
smoke is indicative of the exhaust pipe leaking before the turbo,
causing reduced turbo boost, which causes reduced engine air, which
results in too rich a fuel/air mixture, which shows itself as black
smoke.
