The Stovebolt Site Forums The Shop Area General Truck Talk Exhaust manifold crack

I double checked with the welder who did my manifold and he told me the following:
1.Dimple the ends of the crack with a small drill bit. 2.Preheat to 400 degrees. 3.Use UTP FN 85 cast rod. 4.Peen with an air hammer between passes. 5.Wrap in a blanket or bury it in vermiculite to cool.
