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.
