1969 Barracuda 340 Formula S Restoration
Another thing that happened when I had the exhaust manifold weld-repaired was large pieces of the cermaic coating flaked off!!! This seem to have happened when the manifold was preheated to 400 deg. Very surprised and disappointed as 400 deg is not very hot for an exhaust manifold!!! I put the other one in my garage oven and heated to 400 and a few pieces flaked off on it as well!! High Tech Coatings HTC High Tech Coatings said to bring them back and they will redo them. Just worried that they will flake off when I fire the engine after it is in the car. Not sure if the cast iron was not adequately cleaned or?? Not happy!!!!!
