I cut off the #7 header tube and relocated it around the spark plug. It was too close to the boot and was burning through very quickly. I have AFR heads and hooker 2210's. My problem is that I have put a few new bends in. Tonight I started welding up the tube and can't seem to get on the back side of one bend to weld it all the way. It's close but it leaks. I have sealed off both ends of the header and tapped in with compressed air so I know it leaks. What can be done? Is there anything such as JB Weld or something that will work? It needs to be able to withstand heat and lots of it. Thanks.

 

do you have a picture? Is it possible to weld from the back side?

 

if you don't have access to the back side cut a piece out of the front side and weld it from the inside then weld a patch back over it. it's hard for me to think you couldn't get to the back side to weld it.

 

I had this happen on a set of headers I modified before. What I did was use a torch to heat up the area where I couldn't get the weld. Then dropped some silver solder in there....I sealed up just fine. I have been running those headers like that for 3 years now and they still don't leak. Hope that helps.

 

Thanks for the help guys. I would have tried the weld it from the inside trick if I still had the header. I have Kevin Thompson at Hot Rod solutions redoing everything that I screwed up. LOL!
