Well everything was going well with the removal and installation, something just had to go bad. Well when installing the adapter union into the block for the oil feed line, I was dumbfounded when the adapter twisted off the threaded portion. I then rembered a while back someone having this same problem becuase the adapter was made of brass and stood no chance between me and the block. My question was what or if I could use something from a local "american" performance shop. Possibly an -AN fitting between the turbo and the block in place of ordering a new adapter union. I have a Greddy T78 Turbo.
You probably used the wrong union adapter. You are supposed to use "silverish" looking adapter, it's quite large compared to other "brass" looking union adapters. Hope this helps.
