Low Power, Blown Gasket (Honda CRV)

The owner of this 2007 Honda CRV tells me that it's getting low on power, and making a weird "wooshing" sound when she tries to accelerate.
Don't see this weird problem every day...
Enjoy!

[@rhkips]

A classic example of RTFM. Whoever installed that aftermarket cat clearly didn't read the instructions. Every aftermarket cat I've installed has come with a nice little piece of paper that outlines how to heat-cycle the new catalyst so that the wrapping material inside will seat and bond with the outer wall and the substrate material. If you don't follow these guidelines, the substrate will separate over time and break apart, like we saw here. On a related note, I actually have a video of a Ford Escape that detonated the DPFE sensor due to a melted catalyst that resulted from bad ignition coils and an eventual bad PCM. All that pressure has to go somewhere! ;)

[@SmittySmithsonite]

That was an interesting problem there! Save those pieces Ivan! I've been hearing cat material is fetching some good money at the scrapyards lately. 😎 Back in the day, my ol' man bought a brand new '84 Ramcharger with a 360 V8. 2 years after he bought it, we were pulling the ol' Prowler camping trailer and attempting to merge onto a major MA highway - my ol' man "gave her the beans", as Eric would say, and all you could hear is what sounded like someone cleaning parts off with compressed air! Thing was gutless too, and got terrible mileage. The last exhaust job my ol' man did in the driveway on his '71 Ford F-100 landed him in the hospital with 4 stitches in his lip, when the rusty thing landed on his face, so he got in touch with our longtime buddies at the tire shop, and they jammed a pipe through the honeycomb, blew out the pieces, and we were on our way with all kinds of power, and better MPG than when it rolled off the lot! 😁 The good ol' days!

Great fix Ivan. Most counties in Tennessee have no inspections so we can just take the cats out of the system. It's kind of nice and way cheap. Thanks for the video, see you soon.

[@SmittySmithsonite]

We have to wait 15 years to do that in MA .... and by that time, there's nothing left to the vehicle ... 🤣

[@mattg2226]

@wyattoneable I recently ran into a persistent CAT code on my son's '06 Honda Accord. I'm new into Shelby county now and was happy to see there was no inspection requirement like back in NY. If I pull the CAT as you said, is there a way to stop it from tripping the money light with it removed from the system, or do you just let it stay on?

[@SmittySmithsonite]

@@mattg2226 - I don't want to speak for Wyatt, but I've heard of guys using spark plug defoulers in states that do emission inspections - it has to be of the correct thread pitch for both the sensor bung in the pipe, and the o2 sensor itself. The theory is, it pulls the sensor far enough out of the exhaust stream to trick the ECU into thinking the cat is still there. In the past I've seen websites selling electronics that send out a mirrored good cat o2 signal to the ECU (to me, that's not going to last long being under the vehicle, especially if you live, or drive anywhere there is road or ocean salt). If it were me, I'd put some black duct tape or E-tape over the light - FIXED! :)

Not legally you can't. It's against US federal law to remove emissions equipment. Maybe you have no inspections and aren't likely to get caught but it's still against the law.

Very nice work! Victory donuts in the CR-V afterwards? :)

[@sinegra30]

A exhaust pressure sensor could have detected this anomaly right away... I think at some point Gasoline automakers will have to borrowed that technology from DPF diesel Systems. That sound is also pretty common on Nissan Murano 2004-2007 whenever it gets a clogged catalytic converter... I have been through that before! In my country what mechanics normally do (Not me) is to remove the catalytic converter out of the exhaust pipe, they grab a hammer and a chisel and break in pieces the honey comb structure in the catalylic converter leaving it totally empty and then they reinstall it... of course that procedure leaves a bunch of DTC's on the vehicle but because Dominican Republic does not have emissions regulations they think that is just ok. P.D This honey comb shaped material is extremely valuable so Mechanics collected out of every clogged exhaust and sell it to recycling companies... Technicians even offered to remove it to clients under the argument of fuel economy and future clogging issues...

[@AMStationEngineer]

Due to the Polar Vortex, and the frigid cold which it has gifted the region with, this vehicle needed a more effective road test to determine its true operational characteristics. There is a Tim Horton's on US Route 15, in Duncannon, next time, grab a thermal caraffe of "Horton's brew", and some "Timbits" for the vehicle's owner, and a thorough menu sample for yourself. Of course, you may want to head over to Hammersley..... just saying.... [excellent diagnosis and repair, btw]

Back in the day I had a 1993 Taurus SHO with the 3.2L Yamaha motor. Spark plugs were $11 each for the OEM. I figure I would save a few bucks and get some aftermarket ones. Little did I know they were a little taller than OEM and the spark plug boot didn’t fully seat into the valve cover allowing moisture in. The car started to miss-fire and ended up blowing out the cats!! $700 boo-boo.

I am curious how @7:56 you say you can't tell "if this is bad" because it is a wideband o2 sensor. But the downstream wouldn't be, right? I am just curious why you can't see if the car is running rich or lean due to the downstream regardless of the upstream being wideband or regular. Not critizing just looking for more info-- thanks for awesome videos!

[@bernardaflores1720]

The rear O2 sensor is a narrow band and should read around 0.5 ideal conditions.

[@leo24763]

I had a 1986 Monte Carlo that the cat plugged up. It blew the line to the air pump off. And the exhaust was coming out of that small line. It made a very loud whistling sound.

[@unclechaz8426]

Back in the 80's we used to replace catalytic converters all the time. Some would split wide open on the sides and some would also send debris back and plug the muffler. Next time put your hand on the exhaust pipe and have someone give the throttle the beans. You will feel very little exhaust flow.

[@throttlebottle5906]

I like to leaf blower/air compressor reverse flow the muffler and pipe with the cat out, to make sure it's not plugged, also shaking the exhaust around hard and listening for rattling in the muffler. I learned that the hard way long too.

[@graymodeler]

Thomas Joy I had the first 80 Citation with cat and carburetor. The cat had pellets inside and a plug for removing and replacing them at 30k miles. There was a yellow flag that popped up in front of the odometer at 30,60,90k. There was a service kit of new pellets plug and instructions for removing the instrument glass to reset the cat flag. When NC started enforcing emissions, I took it to the dealership to put my pellets back in, they had never heard of this. Had to go higher up the chain to get noticed. They sucked them in with a vacuum on the tail pipe.

[@frosty98412]

Had a similar thing happen. 00' Yaris, bad ECU, did not read lambda, dumped hella fuel, melted the cat and blew the same gasket after the manifold.

[@throttlebottle5906]

nine times of ten, that's the case, major overfueling or they just kept driving with a mega misfire, alternately, someone "dosed" their gas tank. high alcohol content and other things will melt'em down fast. lean starvation in hot weather also. seen all the above many times over the years..

[@graymodeler]

You would think that rear ox sensor would have thrown a low cat performance code on the breakup of the core. I bought a new cat for my Town and Country from Rock for about $190 and had my mech install it along with a new pipe and gasket. Almost $400 for my case with 170 k.

If emissions were not a concern, one may disconnect cat to gut it and put back. Of course, the money light stays on which can mask other future problems that may arise leaving one unaware and vulnerable to walking. At least it would've kept to the NPR (no parts required) theme as of late... ;)~
