Cordell Posted April 16, 2009 Report Share Posted April 16, 2009 Heat is the only chance you have sometimes, and then it rips out the threads a lot of the time anyway. I had to deal with this shit alot at Monro, most of the time I just took a hole saw and cut the bung out and welded in another. I really hate trying to rethread the holes, talk abotu a a big PITA most of the time. Quote Link to comment Share on other sites More sharing options...

armin922 Posted April 17, 2009 Author Report Share Posted April 17, 2009 ok, thanks will do. The only problem is that i dont have a torch! so if anyone has one i can borrow i would app it. Also, how hard is it to re thread it? i dont know anything about rethreading so if anyone again would be able to help i would be grateful Quote Link to comment Share on other sites More sharing options...
