After a minor wreck, it was found that the mount that takes the bolt that holds the intake manifold cover on was broken on the manifold, opening a hole. Starting the engine and it revd to 3000 RPM, covering the hole and it dropped back to its normal 500. The repair consisted of gluing that mount back to the manifold with JB weld. What is the opinion on this repair? Will it last? Will reinstalling the manifold cover and its bolt eventually break it open again?
