#108493, "RE: S16G Compressor Seal, Center O-Ring, or Rebuild?" In response to In response to 0
When you say compressor housing, do you really mean turbine housing? If you have exhaust coming out of the compressor housing seal, that is definitely an issue. If you have exhaust leaking out between the turbine housing and center section, that is a little less of an issue. I think you'll find that the connection between the turbine housing and center section is like a V-band (machined surfaces are clamped together without any gasket). You might expect a little leakage when cold, but nothing detectable when hot. Perhaps the turbine housing is not tight to the center section because of debris or damage. perhaps the clamp is loose and let the center section vibrate away from the turbine housing. You would probably want to separate that joint to investigate. If you are lazy, you could probably leave the turbine housing bolted to the exhaust manifold.
