the crack on my DC header is similar to the crack in the picture shown. Would i be able to weld this? I'm not really looking to buy a new a header, just tryin to fix mines (for now).

 

You could probably weld it but depending on the exact location, the crack is likely to spread.

 

if your's is like that above, it's gone to hell and it's going to cost a lot to "redeem" it... lol. seriously though, you can fix it but unless you know how to weld yourself (and you wouldn't be asking this question to begin with, probably) or have a hookup to a welder, it's probably going to cost you a pretty penny to fix it. and considering it's a dc sports header which you can find at a reasonable price used nowadays, why go the route of fixing what you have when you can just find another that'll probably be the same price?

 

That happend to mine, i just threw a bunch of JB Weld on it and it sealed it up fine and didnt crack again (i like 15,xxx on it after that before i sold the car)

lol. now that's the ghetto/budget way to go. how's that stuff work anyhow?

 

jb weld is ****. its just an epoxy. ill be surprised if that **** doesnt melt or peel from the extreme heat. it can be easily welded and as stated above it will spread so hit that **** ASAP

 

yea i can get it welded for cheap. I'm just looking for a quick fix lol. I'll probably just start looking for a new one. Thanks for the input everyone

 

yeah you can weld it, while your at it i'd weld over the others too just so it's a little stronger.

 

haha yeah jb weld is ghetto but it was a shitty header so i didnt care and want to spend money on it like this guy. so i bought the jb weld for like 7 bucks or something i forget put it on and didnt notice any problems. deff not the best solution but ehh i didnt care.

 

interesting, my brother tried JB Weld to seal a crack in his stock exhaust manifold, and after curing for the specified amount of time, he fired up the engine and the JB Crap was melted away in almost no time.

JB Weld cannot withstand exhaust manifold temperatures.

 

...Had an old DC 4-2-1 welded at least 10 times over 5 years before I finally threw it away, but I was driving almost 50Kmiles/year so that's not really too bad. It's any easy weld for most shops, should cost no more than 10 bucks.

 

yea imma get it welded tommorow when i have some free time

Since it is a thermoset, it should burn not melt. Perhaps it wasn't fully cured before starting. Regardless, JB Weld is a poor option for an exhaust manifold.

I can't see the picture right now. Is the manifold SS or ceramic coated? I would drill the ends of the crack before welding to stop the propagation. If it is ceramic coated, you will need to remove the coating from the affected area.
