Because of the high temperature swings, JB Weld is unlikely to hold up long, as it has a different thermal expansion coefficient than the manifold.
And, as was mentioned, cast iron is very difficult to weld properly without cracking as the weld cools.
All of this means that you really do need to replace the manifold with a new one.  Do it right and cry once. The alternative is getting stranded somewhere, with the engine in worse shape than it is now. |
Hello
Yes, I have come to that conclusion after reading many posts here.
Thanks to all of you for the advice.
