Exhaust Manifold to Tailpipe gasket

[DaWizard]

Show of hands.

How many of you out there in "A" land have had a hard time lining up and holding that skinny copper and asbestos gasket while attempting to get the clamp around all three parts and slip the nut on the bolt of the exhaust manifold to tailpipe clamp?

Well, sitting here in the garage listening to the rain dump on the roof, I think I have a solution to this problem.

The "indoor folk" have been doing the baking of sweet goods and whatnot and have left me to remove the detritus and while doing this I have come across what I feel to be the perfect solution.

In picture one, we see the antagonizer of this project.

Picture two shows the can used. Now you may use whatever you have laying around that is close to the size needed unless you have a tubing maker thingamajig.

Picture three shows cleaned and sliced.

Picture four shows the gasket around the can for size and fitment.

Picture five shows the finished welding of the can.

Now since I have a resistance solder machine this was a piece of cake for me since it localizes the soldering of the part, but I suspect that anyone owning a small modeling torch or a fine tip for your O/A torch could do this as well. The joint shouldn't really need to be soldered, but to keep the can diameter the same from end to end I would think it should be fastened in some fashion, perhaps a pop rivet on each end would do the trick.

Now since it is still raining outside and I am a dry weather mechanic, I won't be fitting or installing this today, but if you like what I have done so far, maybe I will take pictures of how it fits at installation.

Since I am not totally sure how far the can will fit into reach part I have held off soldering the gasket onto the can, but I am thinking that because I want a real good seal, and the copper does touch the can I may just get a test fit for can distance and solder the gasket to the can after pre-fitting.

Before I installed my Aries I just added a smear of muffler cement to my old header pipe and drove of into the sunset, worked for me.

i didnt use any gasket as per stock and it sealed right up... i was able to hold it with one hand and put the clamp together with the other. Floor jack holding it up helps.

It also really helps to use a small hammer to tap the clamp tighter before tightening the bolts - it really helps it pinch the joint together without relying and possibly cracking the cast exhaust clamp.

Never seen a gasket there!!! I use a smear of maniseal - job done.

A gasket is not needed

Bratton's sell a product called muffler cement, part number 7050. It is a paste that comes in a tube. What I do is put a healthy bead of it in the "V" of both pieces of the clamp. When it dries if forms a seal. I do not use any gaskets or inside pipes. The amount that squeezes out is easily cleaned off. When time comes to remove the clamp it comes loose with the tap of a hammer. The dried sealer is easily cleaned off with a wire wheel or brush.

I agree with everyone that doesn't use a copper gasket just use a beed of muffler cement
It gives you a lot better seal

I never knew there was a gasket for there.

I just did mine this weekend. Permatex copper gasket sealant with some new nuts and bolts and worked just fine!

I know everyone talks helpfully about using a floor jack underneath it, but that has never worked really well for me. The tube between muffler and manifold is situated at an angle and not really perpendicular to a horizontal plane.

Hey thanks for all your opinions.

Ya know, I thought you didn't need any input from me as it seems you all know it all, and all the responses just confirmed it.

It was Real, and Fun, just not real fun.

[iverson]

thanks for sharing your idea its always good to see other ways of doing something! I never knew about the copper gasket!

[SeaSlugs]

Hmm after having to make a emergency exhaust pipe fix on my s10 with a cut up soup can and bailing wire that repair only lasted a year before the can turned to rust chunks/dust... I would not put a can inside to clog up the muffler/rattle around...

Well this is a Forum isn't it?

There was not.
Adding a gasket just fouls up the fit for the muffler clamp.

The gasket goes in the category of repro fixes to problems that don't exist -- until you add it. Like distributor wireless plates!

ericr, I put a 6" piece of 2"X 6" with a couple 1" X 's about 2" apart tacked to the top of the 2 X 6 and put this on top of the floor jack. It rocked enough to take care of the angle and kept the pipe from moving.

I typically have used a small scissor jack (gleaned from a long ago Honda), and place it under the forward most edge of the muffler itself (not the pipe). The scissor jack offers a little more precise lift than does the typical floor jack. I always put a piece of lumber between the jack and the muffler, just to protect things a bit.

What detritus do you speak of or was this a bad choice of words ! Wayne
