Patching hole in a muffler?

If ya have some holes ya have lots of rust and more holes -- replace the muffler and avoid carbon monoxide poisioning.

Thank you for that but I don't have lots of rust and I don't have lots of holes. I still would like to know if there is a substance that can be used to patch muffler holes successfully.

John,

I do believe that you will never be able to patch muffler holes successfully. Of course it also depends on what you mean "successfully" Any patch on a muffler will never last. You can by a substance to patch on a shop that sells car parts or on a superstore. Usually these kits also have a sheet metal to use on bigger holes. I would prefer to spend my money on a good bottle of wine.

There is a Bondo substance sold at say Advanced Auto that can be used - you have to clean area then get wet and apply the heat setting putty (comes in a

3" flat can). They also have a kit with some gause looking stuff - called a muffler bandage. I've used the putty when assembling a new exhaust system on stuborn to seal joints. You then start vehicle and let it run to heat up and cure the putty. If you rev engine you will blow the putty out if not cured. Make sure there are no holes in ehaust behind the heat exchanger cover or you will be poisioning you and your passengers! I conside patches just that a very temporary patch.

what kind of muffler can't be welded? never heard...

Hey John This might sound like a stupid idea but a buddy of mine worked in the military and gave me the idea. It works ok for a while.

Take a soda can. cut it in half the long way and wrap it around the hole. A few cold rivets later your done.

This'll work until you can replace the whole thing. Yes, it works I'm hoping it's not a permanent thing

Sorry for my last post. thats for the exhaust not the muffler. my bad Raul
