exhaust sealer??

I'm having trouble getting a good fit where my exhaust pipe connects to the pipe from the manifold in my 59 Metropolitan. (I know its not HAMB friendly, but the solution may apply to HAMB cars...) Both pipes have flared ends and there is a 2 piece clamp with an indent to hold them together but the flares are small and the clamp is hard to align. Is there some sort of seal or flexible type material that can help seal the joint and stand up to the heat?

 

I have used permetex silicone seal with copper on header gaskets. That may work for you.

 

my experience is that kinda stuff will give u trouble later. can u do anything else using a regular exhaust clamp?

 

there s exhaust sealer that will glue it together
clean, use sealer and ***emble, let air dry or heat slowly with heat gun if you have a real bad fit
when i run my exhaust shop glued a lot of **** together still got a few cans of sealer

 

not having a pic of exactly what you are working on it is difficult to know what to recommend. but, possibly there is a exhaust flange "donut" that goes between the two pipes.

 

I had one of those little ******s when I was a kid and that exhaust setup can be a royal pain in the *** to keep from leaking.

A lot of it has to do with how well your whole exhaust system is mounted along with the vibration of the engine.

You might try to find a new clamp though as that one may be stretched from being tightened again and again.

 

I have used this, dried hard as a rock and has been sealing my damaged manifold joint all summer. And I picked it up for a few dollars.

 

What about the band clamps? Those are pretty slick.

This one time, at band camp... no that's a different story.

 

Red RTV or the copper high heat RTV. It works good and will hold up. i have used all brands with good success for many years.

 

I'm thinking it's two pipes flared flat, then have a clamp sort of like this?


If so you can cut a gasket out of header gasket material, maybe stack two until the clamp is tight and use some ultra cooper to seal it all.

 

Acousta seal best stuff on earth! get it on your paws and youl be wearing it for a while! I wear gloves when I need to seal up the exhaust on my A.

I'd cut the flanges off and use a **** joint band clamp.
That looks like a royal PITA to get on and goop up.

 

Sounds like the kind of joint that is used between the exhaust manifold and the pipe on a Model A. Same kind of indented, two-piece clamp. The trick is to use either the copper stuff (previous post) or my favorite, Qualco joint and crack Exhaust System Sealant. Comes out kinda watery beige, like toothpaste. Clean the joints of any loose rust, smear it generously, clamp it up and wait a day for it to dry. Do it right, it won't leak. Like a previous poster advised, wear gloves.

 

Check out the clamps that are used to join turbo piping. The 2 ends have a bead and the clamp holds them together under high pressure. You can use these for a wider better clamp. Your existing clamps may be sprung or if they are repo, not the same tolerance. Its still a work a round, look at the pipe alignment, I like the donut gasket idea in between them

 

Thanks for the replies. I like the "donut" idea, but I'll try the others also until I get something that works. I'm pretty sure it still has the original clamp but the flaring is so slight that the little indent on the clamp has trouble holding it. I need to get them to mate up 100%, if there is an angle it not only leaks, it comes apart. Another stupid British design. No wonder their car companies go bust all the time.

 

can you take the car to a muffler shop and let them look at it and give you some ideas?

 

Is this something you are trying to keep 100% stock ?
Did you look at the **** joint band clamps ?

What he said I could not imagin that would take from its value.

 

Those clamps look great, thanks for the link.

 

I use those at work and they hold great. If your going to go that route then I would have the top pipe flared so the bottom will slip inside about 2" and then use a step clamp.

 

I have used the joint sealer that is used on wood stoves already & it worked.

 

And all you then is a pipe stretcher, make it 2" longer then expand it for an inside out side fit.
