Muffler patch to withstand backfiring? Or pressure relief valve?
My oval muffler has a 1 inch crack on outside probably due to occasional
backfiring on deceleration. I would like to patch it but I am guessing that the very best patch I can make will not long withstand the backfiring. So I was thinking to maybe put something on there that would block the crack except when pressure is real high (during a backfire). Like a pressure relief valve. Any ideas? Henry |

You do realize that a backfire is an explosion of unburnt fuel inside
the exhaust pipe?? You can expect a 2 or 3' flame front coming out of any hole that lets the explosion escape so how fireproof is the bottom of your vehicle? I had a water issue once and I have a hot timed engine so it does burble on deceleration and when it started backfiring, I was shooting a 2' flame out the tail pipe with each one. They do make really strong mufflers for performance off road vehicles, likely you could make one of those fit. They are heavy gauge welded units that can take rock hits and backfires....

It would probably be best to fix the backfire problem rather than put a
band-aid on it. A backfire is not normal........... "Henry" > wrote in message ink.net... > My oval muffler has a 1 inch crack on outside probably due to occasional > backfiring on deceleration.

But he could repair the crack by covering the shell with layers of
galvanized sheet metal and a couple of big clamps and usind muffle patch material under to seal it for sure. Relief valve? Cool idea. Some of that exhaust gas went into the cabin for too long I suppose. |

Last time I looked 'backfiring out the exhaust' was a real term and was
a symptom of unburned fuel and air mixing in the exhaust pipe and igniting, lots of times caused by an exhaust manifold leak letting air in. I have never heard anyone ever refer to it as a 'muffler explosion'. Is that some new fangled internet armchair detective term I should know about??? I can just see it. Hey mechanic, I got these muffler explosions going on, what gives? Or, Hey, my vehicle is backfiring out the exhaust, what gives? Whatever turns your crank I guess Daniel....

But don't feel bad, people say and write stupid **** all the time, including wherever it was you looked. > I have never heard anyone ever refer to it as a 'muffler explosion'. Guess you're looking in the wrong places. |

Well I guess the OP was just lucky 'he' looked in the same wrong place too so someone who knew what he was asking could answer him eh? He obviously asked something that was way beyond your comprehension so I am glad you learned something new today.

The very term "back" in "backfire" is a reference to flame propagation
"backward" in the induction system- in other words in the intake. But everyone calls popping out the exhaust "backfiring" also, even though its not really the correct term. |

Firing out the back of the valve has always been my understanding of
it. Don't much matter if it is an intake valve causing a back fire pop out the carb or TB or the exhaust valve causing a back fire pop out the exhaust pipe..... This is opposed to firing on the face of the valve like it should in a cylinder. But then I don't know who originally coined the work so....
