RE: [Chrysler300] 300G exhaust manifold repair

Cost of this is interesting to me..Have a couple of broken ones. Furnace brazing is an excellent way to fix it, it will be as strong as original. Welding no good, it leaves residual local stress in the metal. OK on steel, bad on cast iron.



By the way, heads up!!!! One easy way to break them is hang exhaust system head pipe off manifold flange while installing head pipes. BANG, you have two pieces. Tie up head pipe with substantial tie while bolting on, leave tie there until hangers in place and tight.

When I lived in LA, there was a place in Chatsworth which specialized in repairing cast iron parts (heads, manifolds) by oven brazing them.

In other words, they raise the temperature of the entire part high enough to allow the brazing material to fuse and then broughtthe temp down slowly to avoid warpage, This sounds right to me intuitively.

I got a phone call from a gentleman with a 300G that has a cracked right side exhaust manifold.  Knowing how hard it is to find a replacement, can anyone suggest a facility that knows how to repair manifolds?  I realize it is a very specialized job that is outside of the abilities of most welders, but may be possible.  Has anybody found someone that knows how to do the job so it holds up over time?  If it is even possible?  I'd like to help him out if I can, and if you happen to have a replacement manifold you'd like to part with, let me know.
