I don’t fall for no banana in my tailpipe!
She just needed Scottys special convertor cleaner
Eric, you are awesome with your points of service! Great for a learning curb for another 78 old mechanics. Thanks much…
wow a little scotty lacquer cleaner probably could have cleaned that out. Maybe even soaking in Dawn dishwashing liquid LOL
Thank you for doing this….it does help !
You are awesome. You diagnose and repair the correct way. I love it. I always look at your videos. I work the same way you do. I have less experience. Keep thriving. Thank you from Walter, Centex Auto Solutions in Texas.
Great video.
Why do cats get all the blame, dogs have responsibility too! HA! MEOW 😸
Usually on these nissans its the front cat thats gone the rear gets clogged and gives the symptoms you had here so you remove that but after a while the front melts down and kills the engine so its most likly you replaced the clogged cat but you didn't fix the reason it was clogged
How much can someone expect to pay to fix replace the cat?
Nice investigating how plugged up the cats can get
Borescope?
Cut it too
Chrysler polara both mufflers were restricted and we had installed new cats 2 of them ol mike romped on it and blew both mufflers wide open
Wow very little lite seen in there yeah I bet its gotta be pretty heavy
Yes! Some people are oblivious of how their car runs until it quits and won’t start.
That looked EXACTLY like the cat that was restricted on my GTi.
Nice follow up. One of the advanges of watching older videos you can sometimes find follow up videos right away. Ive been really eating up your vodeos over the last month. You're like a perfect pair with my Scanner Danner watching. Just wanted to say thanks and you're a real credit to your profession.
I've heard these things can be cleaned quite well. 8 hours in mineral spirits and 8 hours in Tide with water. Then rinse, blow out, and dry in low heat. Then just weld it back on. The catalyst is not effected by detergent or solvent.
I've seen them totally block the outlet of the cat. Those were fun to (try) to drive! I'm waiting to see how many cats go bad with direct injection and turbocharged or supercharged engines. Should be fun!
What does antifreeze do to them, have you seen that??
Did you try running a gallon of lacquer thinner through the car first? 😉
That cat could have been saved by specialised company ashing the carbon and blowing it out. After that, it is as good as new (and much cheaper than a new cat).
I've found it a couple times on the supercharged motors and usually find that there running 87 Octane gas which causes the dirty burn off and the cat to plug up
Throw back to some of the early years when we had to repair/rebuild GM cats, the flat ones where you removed them and popped the plug and dumped out the old pellets and poured in new ones and reinstalled. How many here did that?
Thank you for following up!
I was hoping you would have cut that cat open lengthwise 😉
Thats amazing that reduced 80% of the motors performance…How many miles are on that cat? thax….I took out my o2 sensor on 4.3 blazer today and started the motor and it reved smooth and powerfully… i most definitly have a clogged cat also… with 02 in it barely runs at all about 20% power….thax for sharing
That cat was plugged!! I seen a guy in town one time hammering that cone out of his converter with a long screw driver. Bang bang boom, Pieces falling out everywhere. A little too obvious what was going on there.
Forget what I said in the diag. vid. Thanks for the video. That's funny, grandma with a super charged Buick. I can see her now doing hole shots from light to light….
:55 Next time use the Rigid chop saw on the shelf behind you.
Can you get a hint of plugged exhaust by hand over tailpipe with motor running?
How long was the air filter being bypassed? That's where the debris came from.
The original engine was blowing a lot of oil through the exhaust or running very rich.
I have seen 3 Buicks with the 3.1 and 3.8 bad cats around 100k miles. maybe its something to do with the intake gaskets causing oil burning issues.
I've only been burned 1 time on both a cat and muffler being plugged. The cat broke loose, and some of it got into the transverse muffler. Of course you could suspect all day, but there was no way of knowing w/o replacing the cat and front pipe assembly 1st. I found that out after the fact… In other words, that car needed an entire new system front to rear, and unfortunately, it was a tough sell…. ( In case you're wondering, it was on a 02 Camaro w the 3.8. )
Cool thanks
Somebody used an additive containing lead.
Come on people's 5 more to hit 75,000 sub's…. good info thanks fer sharing…..
Pretty nice patch on the exhaust! Have done that with gas looks like I need might! thanks!
back in the 80's i used to take the cat off and gut it,,, a hammer and a steel rod and break apart the honey comb and good to go,,,, i bet she drives around town all the time,,, i make sure i take my truck for along drive at least once a month to keep everything cleared out
Just a little info on this… These GM cats, with the double wall tubing in front of it, have an issue where the insulation between the two tubes breaks down and clogs the cat. Seems like there's no way of preventing this from happening.
what…no brake clean? ….LOL
Hey Eric thanks again for doing these vids for guys like me trying to learn. One question – would the downstream o2 sensor give you any indication for this? Maybe even something you could use for this diagnosis? Thanks.
is your paper weight in front of keyboard a Tecumseh alternator adapter for a light kit on snow thrower?
thanksssssssssssssssssssssssssssssss so much
Here its eather cat, dpf or in winter time last mufler. As it is frozen from too short trips to shop and back.
You know you should wear sandals when cutting stuff like that
Holy Frioles
I was expecting a white molten mass the size of grandmas meatballs in there. Oh well
"A really bright flashlight"?? Bitch please 🙂
