Thread: leaky header tubes

Tweet

I'm positive it isn't the collectors.
There are welds all over these pipes, I pieced them together out of about 30 small sections of tubing.
Right at that point halfway down is where all 4 come close and coincidentally there are also 4 welds all within an inch or two.

thats not good then. I don't know of anyway to stop it if you can't get to it. use the trans. fluid and see if you can find the leak and then maybe you can come up with something.

Melting some brazing rod onto it sounds like about the best solution so far.

The headder wrap is a good idea, but not to muffle the sound. It won't muffle, and the leak will probably blow a hole in the wrap eventually. However, after you make them good-n ugly melting brass all over them, cover them in thermotec wrap, and paint them in your preferred color of hi temp ( aluminum looks great ) and they will be beautiful again, you'll get the performance advantage of keeping the heat trapped, and you won't burn yourself working near the hot headers in the future.

one more thing: in my experience, I have found that whichever method results in the most labor, is the right choice when working with headers.

Putting header wrap on it would be like putting a band-aid on a severed hand...it's still going to leak.

I'm betting that it is coming from one of your connections where you welded them together piece by piece.

cut the tube off were you can weld it back on. you will need to cut off the collector take the tube out find the hole. weld it and weld it all back up.I have fixed bent headers this way many times when they hit the track
