The problem I have is I want to move my catch can forward a little bit in order to make it easier to drain. I reused the nut that originally held on the silencer and it's is completely frozen to the stud - I'm not talking about the captured hex and washer on the engine block side - this is the 10mm nut that held the silencer in place. I have soaked it, put it in a vice, etc. - it will not move. It did, however, manage to move just enough at some point while tinkering with it so that now when I remount everything the catch can is at about a 45-degree angle. :laugh2:
I finally just took the catch can off after much frustration.
