On my 1992 mustang the vortech drain 3/8 npt fitting is loose to the point that it will no longer thread. You can pop it in and out on the side of the Canton oil pan. Made the mistake 10 years ago to just punch and tap and not weld while the pan was out. I had this same issue 2 years ago and rigged it with teflon tape on the treads and lots of black silicone around the fitting. I do not want to deal with this again. What do you guys recommend to repair this without pulling the motor out? Wondering is it possible to have someone weld, mig or tig the fitting in place? Has anyone done this? I did a search and did not some up with any answers.
