Re: {Chrysler 300} F Manifold

Have you looked in our archived emails as I suggested a few days ago, under 'exhaust manifold repair' to search out communications on possibly repairing your cast iron exhaust manifold? From your initial August 1st email, it sounds like you are referring to the exhaust manifold, and not the cast aluminum ram intake manifold, correct?

Here are copies of some relevant responses. I don't know if the repair shops mentioned are still in business, but you may want to check them out and explain your situation in detail.

I had the left side exhaust manifold on my 300F repaired by Paul Russell's shop in Essex, MA in the late 1990's. Note: He's the guy who does all Ralph Lauren's cars. Now, before you fall‎ over scared by pricing, I have to tell you he was very reasonable (I don't recall what the price was, unfortunately, but it was very palatable.)

As you can imagine, his guys deal with big issues with super-high dollar cars all the time. He gave me a tour of his facilty and Lauren's Concours winning Bugatti 57C was in his small lobby‎, as he stores some of Ralph's cars as well. Needless to say, I was pretty much awestruck.

Anyway, worth considering and a call to them.

Good Luck,

Keith

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.

Neal,

I had the same problem with the passenger side exhaust manifold on my 300F.

I had it repaired at this company here in California, Lock & Stitch, since I couldn't find a replacement. The neck was broken into two pieces. They did a great job, however it took them a long time to do it.

A resource for repairing broken exhaust manifolds is :

I’ve heard good things about their ability to repair manifolds.

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.
