ok, my exhaust manifolds have some annoying leaks and i dont have the $$$ or the time to fix them. I heard JB Weld is suppose to be some pretty darn strong stuff. My question is, could it hold up to the heat of the manifolds? I need something for them, the trunk side one has been welded up a few times before it looks like and is still cracked, you can actually hold your hand near it and feel exhaust comming out

I know it works well on cracked engine blocks, but I don't think it would stay on the manifolds, quite a bit more heat there, especially on the Fiero's thin ones

As long as the stuff isn't flammable, there's not much to loose but trying it other than a couple of bucks.

I don't think JB Weld will stand the heat.
There is some kind of sintered metal glue manifold repair but it is for cast iron manifolds. It is made by permatex. http://www.permatex.com/auto/autouh.asp?automotive=yes&f_call=get_item&item_no=26346

No JB won't do it, on the exhaust that is, been there, done that. What i did do on my old 79 Chevy pick up, IF you have the room, or depending on exactly where the crack is, I took some aluminun foil, folded it up a few time to make a long, slender patch, wraped it around the leak area, then tightened a hose clamp around it, real tight. Working now for about a year and a half!

Been there...... done that.... Forget JB for the manifolds. Burns out in about 60 seconds!! Have the manifold welded or replaced with a new one($$$$$)

Thanks Bigfieroman! "Fixed" the high pressue side of a power steering hose in similar fashion on a 86 Camaro once, just to get us home, approx 40 miles, only that time I used duct tape, and a few hose clamps. Wraped the tape around a few times, then clamped the site, and then either side. Like I say, got us home.
And spark1, the problem I had with anything applied, when you start to give it hell, the pressure usually blew it off pretty quick. Just my experience.

ah rats, i wish i would have remembered to read this thread before i did it today. I guess ill find out on my own eh? stuff only cost me 3 bucks with my employee discount anyway
