I'll bring your comments up with him at lunch.Had to use a breaker bar? Should NEVER have to use one. I found on one of mine was leaking and found out the bolt was bottoming out, like they didn't have the hole deep enuf. Took the banjo bolt and ground down a thread and put it in with MINIMAL effort, done and no leaks
I think after he looked the system over and tried all that I had done and my A Body friends had done, he took the course of 'brute force tighten until the leaks stop or be damned'. I would have never taken this approach (as most of the fittings are now damaged), but I must admit he eliminated all of the leaks.
