exhaust problem revisited

[Jay Darst]

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.
