Suddenly there arose from the porch (or under the engine) a great clatter (or loud noise).

Today, I think I got a hole somewhere in the anterior part of my exhaust system--there is a loud noise from up under the engine (and under the hood), I push a rag up to the exhaust and seal it off, and there is no change to the engine running.  

I will not have a chance to get under the car until next weekend to try to patch it, but what to have handy when I finally get under there?  If it is something simple like a small hole, loose bolt, poor seal, etc, I can probably take care of it myself, but much more than that, and I don't have the time to hassle with it.  

What works best to patch small holes without replacing components?  

The vehicle in question is a 1994 Ford Explorer with 109k miles.  

Thanks!!

    Use JB WELD, it is an epoxy compound that will seal and bond metal, plastic, ect.  You can pick it up at any auto parts store.

They sell kits at autoparts stores.
basically its a pre curved peice of sheet metal and some wire and usually some sort of epoxy.

You can cobble the stuff together from your garage if you want,  but for epoxy I recommend jbweld or some other sort of high temp epoxy.

They also make a product called Muffler Bandage, It looks like alum. tape...

That stuff usually blows/burns out after a while.

yes, Jungle Bunny weld works well...for those special nigrig jobs

Depending what and where it is,  just get it fixed.  


Sorry,  something like that would drive me nuts just knowing something was wrong with my car.  And I would have to get it fixed.

I'm sure one of these guys would be more than happy to plug your exhaust hole.

sorry I couldn't resist [;)]

Maybe its the "doughnut" that goes on where the exhaust attaches to the manifold (if they still use them).  Just take the two bolts off the flange and drop the pipe and slip a new one on and reattach. But might be easier said than done due to no room and rusted and frozen bolts.

You might want to check the header bolts and make sure that they are all tight. Usually, if any of them losen up it will start off as a light "ticking" noise and can develop, sometimes rather quickly, into a full blown monster truck sounding exhaust leak. You'd be surprised how loud a small leak comming directly out of the head can be.

If this is the case, it's probably too late to just tighten the bolts and you'll probably need to replace the gasket.

If it turns out to be a hole somewhere, depending on where it's at you should be able to take it to a muffler shop and they should be able to fix the hole, unless your exhaust system has turned into a rust encrusted blob where you might not have a choice but to replace components.

It should be pretty easy to figure out where it's comming from once you start seriously looking. You can always take a long pipe or tube and move it around your exhaust, with the car running, with the other end up to your ear. It'll get really loud when you're close to it.

Should be an easy fix this way

Just wrap the aluminum muffler tape with bare copper wire.Let it run in the driveway at idle to cure before you drive it.You might want to get the gasket were it "y"s into the cat converter and the one after.Heat fom the cat takes its toll on these two gaskets.
