Rattling Catalytic Converter

[@solomonromeci]

Exactly brother finally someone who understands my pain thank you so much after years and years you are greatly appreciated keep up the good work

[@masonwabevalashiya4247]

Thanks alot Bro. I've searched everywhere on the internet trying to find out why my car sounds like that!!!! This video helped me to find the cause!!!!

[@driver6629]

I was on my home the other night and i could feel my car missing. Well, that missing turned in to violent bucking and backfiring in the exhaust. This ended with me pushing my dead car off the bottom of an off ramp on to the shoulder. After a 50 mile tow to my mechanic it was diagnosed as a failed IGNITION COIL. The night that I got it back it started making this exact noise. The car is over 25 it doesn't need to be inspected anymore so today I ordered an off road X-pipe. Your video was perfect! Thank you!

[@eddiehenriquez3990]

Is it legal to run catless in your state? I was thinking about going with the same off-road x-pipe but it wouldn’t be too ideal for me.

[@Jihadbearzwithgunz]

02 blazer xtreme also has a similar sound and was pretty sure it's the cat as it's loudest around the cat quite from the engine bay and also near the muffler and would be noticable there as it has a 90 out the muffler straight to the ground.

THANK YOU! Took my car to a “mechanic” for spark plug replacement. My car stared to shut down when parked. He told me he had over 50 years experience and he knew what he was doing. And that I was over reacting to the car shutting down. That my needed to get use to the new spark plugs. My car wouldn’t accelerate, so he drove it and put gas to the floor to make it drive and said car was driving fine. Next day I found the boxes he left in my car for the spark plugs he put in my car. … took it to Autozone and they said it wasn’t fit for my car. I bought the correct ones but within a day- the spark plugs he placed in were burnt out. And was causing so much misfire. My car is still acting worse now. And I was told my catalytic converter is now acting up. It is creating this noise now. 😭😩 ALWAYS TRUST YOUR GUT INSTINCT!

Mine does it only when accelerating. Does yours?

[@ImTheDaveman]

@@fishingmaster99 Since I posted this, I found out that it's more likely the heat shield is loose. It rattles when running idle, but doesn't get much louder or pronounced when accelerating - just a little.

[@OldDays99]

​@fishingmaster99 that is when mine has the sound as well. Has your issue been fixed by replacing the cat?

My 2011 5.3 gmc started making this noise and stalled out. Had it towed home and I figured it was the cats broken inside. Glad to have found your video to prove the problem without wasting money on unnecessary parts. Will take the exhaust apart tomorrow.

[@markgunther2502]

The new ones just deteriorate over time. I have a cat I only use for smog checks but I've been doing that for about 16 years, however it only gets about 10 miles on it per year. Thus it probably has about 160 miles on it. I noticed just a couple years ago, the insulation that I holds the catalyst in place inside fell apart and stated coming out the pipe ends just from sitting in the garage. The catalyst is now free to bounce around and makes quite the racket, however, the catalyst works fine and lowers emissions the same amount as it did when it was brand new.

[@leetos.4915]

Hi mate I totally agree with you that honey comb breaks down as part of wear and tear inside a cat regardless how well an owner does regular maintenance on his car . I'm going through same experience right now with my 2017 ioniq at 250K mileage and starting to hear some weird noise within that cat converter when I accelerate at times ....I figured I could extend the life of my converter as long I keep my regular maintenance like oil change air filter and other basics...once theres much consistent rattle noise during driving then it's perfect time to replace my cat once and for all

[@MrSupercar55]

And don’t forget a good Italian tuneup!

[@TheIpadiphone]

Thank you I was hearing a noise from my exhaust by I never thought it would be the catalytic converter. You do talk about finding the cause of the fault but my truck doesn’t show any signs of misfire or and engine problems, the only thing I can think of is a few months ago someone half cut the other catalytic converter and I had to drive my truck about 40 miles to get it fixed

[@vivian5517]

There could always be another issue or it could just be wear and tear and years of using the vehicle is what I was told. Good to check and make sure there’s no other root issues but if there isn’t, it was just time to replace

[@ciklop4206]

YOOO THANK YOU. My EcoPoof 2.0 Volvo V70 is making a really similar noise. At first I thought it was the chain, but after a replacement it didn't go away. Next, I was thinking that the wastegate on the turbo was loose, but the noise and performance indicates otherwise. Flexplate was the next painful thought. After I stumbled upon this vid, I had a sigh of relief. Changing out a cat is much better than paying someone to rebuild the engine 🙃

[@a_23656]

I’m trying to figure out sort of a similar sound when I accelerate in my 2013 2500hd. 73,000 miles. Only when I get on it to pick up speed. Sounds more like loose change. I’ve heard it in older vehicles along the years.

[@BarboursAutoHelp]

Spark plugs with 235,000 miles on them could definitely cause catalytic converter damage, especially if the vehicle was misfiring.

[@micah_noel]

I have a very similar noise, like a tin can being rattled around. But it only does it at certain moments. It’s worse when I’m slowing down, coming to a stop and especially while turning. When I’m in P, I only hear it very slightly when I give it gas, otherwise not at all. Doesn’t sound quite like the steady rattle in this video, which I’m assuming was occurring while the gas pedal was not being accelerated. Any ideas?

[@micah_noel]

Okay, so I think I found where my rattle is coming from. It’s the top part of the enclosure of the cat. I don’t believe it’s internal. So I’m wondering if I can’t just hose clamp it. I’m not certain how it was constructed to begin with… welded or riveted? I didn’t see any fasteners on my brief glance. Are sealants necessary to prevent exhaust leak?

Im having the exact same symptom with the same engine. Did you solve the problem? Was it the catalytic converter?

[@Thought_Criminal_13]

I have sifted through all the nonsense advice on here and I have come to the conclusion that I have a catalytic converter issue. What I am dealing with is when I try to accelerate when I reach about 2000 rpm’s I hear a loud sort of whining sound like the air is having trouble passing through. I noticed when me and my buddy were diagnosing the issue when we stopped pressing the gas you can hear something clink down like there is a small piece broken in there. No where near the clinking in the video. It just sounds like one small piece broken. It’s like the air flowing through elevates the broken piece and then when it stops it falls and makes a clunk. It’s definitely having difficulty going up hills. I have stayed off the freeway since I noticed the sound and the reduction of power. It’s a 1990 F350 if thatbhelps. Does this sound correct to you?

[@brentbarnfield8284]

It’s only coming from my drivers side.. if I take it apart and am able to remove some loose pieces, would it get quiet again? I cannot put anymore money into this vehicle.

[@Datboifresh02]

This was awesome! Dealing with this problem now.

Thnx. for this video and info. My 2009 fx 35 has 178000 mls and there is this rattling sound that it make when the engine is idling or running at low speed. This rattling is not audible when the engine is revved, or when you are driving. ONLY WHEN IT IDLES, THROTTLES, OR DRIVE A VERY SLOW SPEED. Two mechanics told that the cause is from the timing belt guide, and the tensioner. ONE MECHANICE said it may be from the Catalytic Converter. I have never heard it before that a engine rattling could be cause by the C/converter. But after watching and listening here, i am now more prone to think that this is my issue. The vehicle drives excellent and accelerate with not rattle, what so ever at high speed. Could you say anything about your thoughts on this issue, or is there any one out there that would like to give a input on this, I would be appreciative.
