Small exhaust manilfold leak!

Hey guys,

I have a very small exhaust manifold leak, that is not worthy (yet) of pulling the manifold and replacing the gasket. What do you think would be the best way to do a temporary fix?
I was thinking of using an xacto knife and sliding some JB Weld into the opening to fill the hole. What say you?

Murph I know, I spelled Manifold wrong

 

JB Weld won't hold up to the heat. You need Thermosteel, sold at auto parts stores everywhere

 

Hmmm, never seen it, I'll take a look...Thanks

Murph

 

Just fix it. It's not hard.

 

i crack a manifold on my 429 caddy motor i uesed some stuff that por-15 makes it lasted a while but i only had it for afew weeks till i found one

 

thanks for reminding me, I gada go to pep boys and grab a couple tomorrow for the header.

 

Bite the bullet and fix it before the leaking g***es erode the gasket surface to the point that you need to get it milled to restore the gasket sealing surface.

 

Do what he says....you'll put it off and alot of other things will get screwed up....................

 

Don't know about other motors, but Chevy V-8's came with no gaskets on the exhaust manifolds. They do come in every gasket set but I never use them.

 

I'm with Unclee. A very thin smear of high temp silicone (Permatex Ultra Copper)if there are any pits. I think that the Ultra Copper is just the high temp red with copper dust in it.
