I have a crack on my exhaust manifold and was told by a mechanic that welding doesn't work well. I was wondering what is another way to fix it, without replacing it. Liquid metal ect......

 

I've seen manifolds welded with mixed results.

 

junkyard or get a header maybe try steel JB Weld

 

pics of said crack???

 

what year accord?

It's pointless IMO, go to the junkyard and get another.

 

go to the junkyard and get another one man, easy pezy.

 

It's only rated to ~600*F, Exhaust temps are double that.

 

Get another manifold. I just gave my stock manifold away to the scrap yard. I,m sure someone out there has one for you. Or buy one from the yard, or get a header.

 

Or you can just get an Ebay Stainless Steel brand header for $99.00 shipped. All the SS headers I bought off Ebay for my Accord does not leak which I ran for temporarily til I got my Hytech Header installed. Just don't go under one hundred for Ebay header as they may leak.
