Hello, I'm new here, so if I am at the wrong place, just tell me and thank you


I have a main issue with my 190d 2.5 from 89... First, is this pipe (obviously someone touched it) from a previously turbo install? My car is no turbo from stock but many years have passed! Someone told me is the turbo sewer?



Second thing is, what is it used for? And how to "seal" it? Is there a designed stock screw for the job? Thank you very much!
