My exhaust is leaking right here in the middle of the clamp, I can feel the air coming out. My first question, is this dangerous? Next is how hard of a fix is it? Can I patch it with anything? I can’t really find any YouTube videos on that type of clamp. Please help!
ChrisThat just surface rust, hit it with a hammer few times and those threads look good so heat em up, remove nutz and replace gasket.
WyattTake a bolt induction heater to it, it will be needed then pop it off and there is a seal inside that flange you will probably have to use a screw driver to get it completely off, and I recommend cleaning the surface where it mounts than putting in a new gasket/donut.
JoshuaSoak bolts with WD40 over night. Run it for a few minutes so it’s hot. Remove the bolts. Throw new gasket on. If it’s warped really bad use 2 gaskets.
DavidUnless you’ve got a decent flux core machine with a flex neck, a ton of experience, and a jolly load of free time, I’d take that into a muffler/exhaust shop and pay whatever they ask.
DavidUnbolt both flange ends. Replace gasket. Bolt together both flange ends.
RichardIf it’s only leaking from that slit in the flange, you probably just need the gasket or donut applicable for the exhaust system. We’ll, that and cleaned up so the gasket or donut seal good.
TerrasonAs long as the metal flanges are good, get those bolts off. I usually grind them off. Then replace the gasket inside with new bolts. Done.
OscarTake the bolts out and buy a new gasket. I think that’s what they are called. Those bolts look like you may have to cut em off. I always use a grinder and make a couple cuts on the nut to get it off, and then punch out the bolt. I don’t think you’d wanna cut the bolt in between the two flanges, as that would make the gap between them larger and still be loud AF when you put the new gasket in. It should only be a few bucks at the Autozone. Harbor freight has decent cheap grinders for around 30 bucks if you need one of them. Wear safety glasses, watch a how-to video on YouTube on the grinder if you’ve never done that.
Brad30 years ago, when I worked for Midas Muffler, they had an exhaust pipe sealer that we used that dried hard. We would put it on all of the clamped joints as a precaution against small leaks. I don’t remember exactly what it was called. Any repair may end up being a mess.
BlaiseReplace exhaust gasket between flanges and clean off as much rust with wire brush, definitely take it to a shop unless you have some sort of torch or induction heater, will 110% snap.
DonA couple of hits with a hammer to knock the rust off the flanges and a zip cutter and toss the bolts and there is a gasket between. And to the right things are looking kinda brown, so perhaps that is on its way out as well. That is not air your feeling but exhaust.
DavidTake it to a muffler shop. If they are honest and efficient, they can cut out the rusty flanges and weld it together reasonable. Odds are it isn’t dangerous, but you could potentially get exhaust fumes inside the car.
StuartTheirs a gasket between separate flanges give it a good wire brushing sand paper then new gasket.
FredDoesn’t even look that bad….heat it with a damn smoke wrench to remove the nuts, needle scale the flanges, and reassembled with new gasket and hardware! 20 mins with the correct tools and equipment!
ChrisI work in a shop where they started 35years ago doing exhaust only. Been there on and off for close to 15yrs. Honestly, that needs a new gasket but being rusted as that, I’d cut each side of the flange and put a piece of pipe and weld it.
MikeIf you’re not wanting to dump a whole bunch of money into it, just high temp JB weld the crap out of it and that should fix your leak.. Or cut out flange and Welding pipe
MarkGet an exhaust gasket and 2 bolts and 2 nuts and some sand paper take the two nuts off if it snaps oh well that what the replacements are for if you need em sand any rust down on the mating surface.
Place the new gasket between the 2 flanges install bolts and nuts tighten then evenly done easy job once you have the parts takes maybe 10 min depending on how bad the rust is.
TonyIf them bolts aren’t welded into place just cut off with grinder where nut is , tap bolt through, part, clean up, new gasket, 2x new bolts.
ChasCut the flanges off, then go to an auto shop and find the right size pipe. It’ll help to bring part of what you cut so you can see what fits snug. Looks like 2.5 or 3in diameter, but just play around with the connector pipes and grab some you bolts to tighten up the new ends. JB weld or muffler cement around the edges or weld it if you’re handy. No need to pay a shop unless you aren’t experienced but what better time.
Yes it is harmful if you have your vehicle in a space with no ventilation, or you have cavities in your floor board, otherwise you’re safe.
GusThat’s not really a clamp. It’s two flanges at the end of the tubes, mating together and bolted. You’ll need to replace the rusted out flanges. That’s probably a job for a muffler shop.
