Do what you want to your own engine ... I will do mine to last the long haul. You may not have any problems to date at 2,500 miles and counting Brad, and good for you. I hope nothing happens to your engine for centuries to come, but I doubt that will be the case. My hat is off to you for doing the mods and offering to help others do the same, but I would never do this with JB Weld ... too many "what if's" for me.
