Turbo Gasket 900 1994

Does anyone know if there is a gasket between the cast turbo housing and the exhaust pipe. The connection I am speaking of is where the exhaust pipe connects directly to the turbo casting. My car has three bolts and all three turn freely. I could hear the noise it was making and feel air escaping from the connection.
Thanks in advance,
Hawkeye

    Here are a couple of parts schematics to help you. Mildy surprising to me, it appears there's no gasket or ring between the turbo and the exhaust manifold if that's the flange you're talking about, but it's 4 bolts, not 3. Is one of your studs sheered?

      That is the connection I am talking about. I assume the turbo I have (Mitsubishi) just has three. I tightened the top two but have to get under the car to get the third one.
      That's helpful. Thank you very much. I'll report back.

        Hello, there is no gasket. The turbo and exhaust mainfold are flanged and seat together. There are four nuts that hold the turbo to the manifold. They can all be reached from the top, but the bottom ones are difficult to remove and install because of space constraints.

          The turbo had only three bolts in a triangle pattern. I was able to tighten them and the exhaust is quiet again.

          Thanks for the replies.

            You are correct, I didn't read carefully. That turbo to downpipe also does not have any gasket, just a flange in case you were wondering. This actually makes O2 sensor removal easier (if it's stuck).
