Re: {Chrysler 300} F Manifold - JB Weld

[Ryan Hill <ryan_hillc300@xxxxxxxxxxx>]

Though I would never recommend JB Weld for this particular task either, I have to say I was impressed by the stuff back in the 1980's on a different type of exhaust manifold repair. 

My Dad made the mistake of trying to get our Winnebago off the freeway one hot summer afternoon when we discovered we'd lost a fan belt on the 1976 Dodge 360. By the time he got it to rest and shut it down the engine was overheating badly. Replacing the belt took a few minutes once it cooled down but we discovered a large exhaust leak immediately. Upon removal of the manifold, we found the flange had actually warped quite dramatically on the centre ports and would no longer seal against the gasket. 

With the manifold off, Dad spread out what I recall being about 3/16" to fill the void and filed the mating surface flat as a temporary fix. It lasted more than 5 years and 10k miles before it burned out...... That was probably 35 years ago and epoxy technology has improved considerably since then.....just sayin'.

I'll second that. You will be well advised to spend time seeking a replacement than a welder. The fellow who proposed JB Weld, an epoxy, a plastic, must have been kidding. I hope so.

In my opinion, the task is nearly impossible. There has been discussion on this topic in the past and I don’t recollect anyone having more than short term success with a manifold. The process requires the manifold to be heated to an almost molten state before a weld can be successful.

Well I received a call from the welding shop I took my broken manifold to today. They were able to weld it together but upon striking it with a hammer to make sure it held, it cracked again. Then the welder suggested I use JB weld to fix it. I don't know if it cracked along the weld or elsewhere as I haven't seen it yet but I plan on picking it up tomorrow and taking my business elsewhere. 

Does anyone in the Midwest or Southeast Wisconsin area have any recommendations of a welding place that can handle a cast iron manifold? 

Thank you in advance.
