did not change the housing to manifold gaskets.. those were in extremely good condition. also did not change the smaller manifold to turbo. downpipe i have visually checked and no leaks there.
it looks like a bad leak due to the rebuild smoke at the moment,
but in the past honestly the only times i noticed it were during deflood when a few wisps of white exhaust would float up from the area.
i guess maybe this is where i should have spent the extra cash and bought new gaskets, not sure they looked pristine and i had them cleaned off pretty good
