Its funny when people bash mechanics as non-educated wrench turners, and you start throwing chemistry terms at them that they don't understand explaining how a car works.
it's exactly the same with people who build computers now... anybody can plug one together.
Joseph Stott
yes darling?
Joseph Stott CompTIA A+ can fix that. Lol.
+1 for the cat joke and +1 for mentioning Tom Ogle and the petro dollar--and +100 for have backyard chickens! Great explanation of the whole process.
+Eddie Padilla hmm... if i ever have the time (IE in several years) i'll try to remake the ogle carb with a shop vac, though i'd have to try to get it to work with EFI though, if that fails there are a bunch of old trucks i could buy here

subtle things can alter sleep patterns in kids, L, for example, some little guys are more sensitive to cold so wearing socks might is one idea, another is using some source of white noise to block outside traffic, people, and creaking house sounds. I used a fan, for example. Pillows and sheets/bedding can be a source of subtle irritation, too. For example, micro fibre sheets, down pillows (with lots of feathers, typically), or inadequately rinsed bedding - leaving residual detergent or fabric softener- is often a source of breathing congestion, wheezy runny nose discomfort which keeps the kids (and you) from getting good deep sleep. And make sure your window sills are free of molds and dust. Many folks dont realize that molds respire too and its their exhaled breath that our own bronchii react to.
Hi Brian! It's Shep the Jewish me-chan-ic. Riddle me this "Batman". 3 years ago I replaced the engine in my 2000 S10 (2.2 liter) with a new GM crate unit,along with the injectors and pressure regulator (Sorensen),fuel pump (Carter) o2 sensors (AC Delco),and Cat (Walker). 1 1/2 years ago a p0420 code appeared. No vac or exhaust leaks. Fuel pressure is correct. No misfires and engine vacuum is rock steady at 18 inches. In short, the truck runs great. AutoZone replaced the cat at no charge. Last month the p0420 code reappeared.Same conditions. I ran a live data test. U/S o2 sensor readings bounced all over the place (as it should).D/S o2 readins did the same (as it shouldn't). I replaced the cat (again) and now the D/S reading are .73--.78 volts at highway speeds..43--.47 at idle. And ..50--.53 at around 35 to 40 mph. In other words , steady. All other readings are normal. My GM tech friends say I need a factory cat ($1000--$2000). My independent tech friends and my old auto tech instructor ( the 1 who taught me 30 years ago and is still teaching) say that's nuts and a Walker $179--$400)or any cat should be fine. Any ideas? Thanx and G-d bless. Shep.
so, we start off with bad cat meows and i'm ready to click "next", but i wait for a minute, and am treated to a very informative (and very eclectic) video. i really liked it. thanks for reminding me to not be such an a-hole. :-)
+Lyle W Lyle, you're alright man. Great to hear from you!
+briansmobile1 @5:15 it got a bong and it's 'high' time, lol!!
+Lyle W If you have ever seen a briansmobile video before you would know what to expect. His videos are great.
and yet im sitting here wondering what they look like when you spit flames through them. also what is a highflow?
Agreed. That joke was so bad I almost clicked away, but very informative. Glad I stayed.
Best damn explanation on how catalitic converters work!
I also remember the predator carburetor. It multi staged gasoline through values that would compress the gas through charcoal filters. The damn thing was almost 99% efficient in burning fuel. And was way cleaner at the exhaust then today.
I still use a water injection system that can pass any inspection station probing.
Well, I'm 2.5 years late on this advice, but when I was a kid, my parents got me an Indian dream catcher to hang on my wall, its a round leather loop with some feathers hanging off, and beads. They told me it would catch the nightmares before they got to me, and it worked. Placebo effect FTW!!!
you drew me in with the meows but i stayed for the vast amount of knowledge
as far as the nightmares go Brian, what I find works for me personally, if I watch something that is creepy, then before I go to bed, I watch at least a few minutes of something funny, like a stand-up comedian, to give my mind different thoughts before I go to sleep.
No. Cats can last a long time as long as the engine is efficient (relatively as far as autos go) and doesn't emit HC's CO's etc. When a car has problems burning these completely it heavily burdens the cat and burns it out. A plugged cat can inhibit proper performance and create back pressure at the exhaust port which can reduce fuel economy, but something was wrong with the car to make the cat fail to begin with.
you are so incredibly intelligent. this is so useful, I've learned a ton in 10 minutes
Test where the compression loss it BEFORE pulling the engine out by making sure all the valves are closed on that hole. (#6 by taking off the valve cover and inspecting cam position) Brace the crank so it won't move. Then run shop air into that hole and see where it comes out. The possibilities are.... radiator cap, oil cap, exhaust pipe, intake manifold. From there you can tell if it's valves, piston rings, cracked cylinder, head gasket etc.
This video is the perfect example of why I enjoy watching your videos. You got auto, biography, sports, chemistry, economics and comedy all in one pot :-) Shucks how could I forget the cat and chickens?! Cool video!
hey brian, just wanted to say that as a chemist, your explanations are spot on.
one thing to mention about the "super carburetor", the vaporization of a liquid under a vacuum makes the liquid extremely cold very quickly which is probably a bad thing for your gas.
cool video
thanks. Last night it was a 1:30 am episode of wall kicking for like 20 minutes running from a wizard.
Yes. The only difference is the thickness of the core walls within the honey comb. You have to maintain gas density or the temps and effectiveness suffers. So what they do is make the ceramic thinner so the hole count is higher. GREAT QUESTION!!!!
You are spot on about the carbon monoxide thing. The CO bonds directly and irreversibly to the seat on the bus (on your blood) where the oxygen is supposed to be. That means oxygen can't get on the bus and get distributed where it needs to be in the blood. When CO bonds, the blood gets bright red but that "seat" becomes useless. Blood only has so many binding sites and oxygen deprivation can have term effects, even at lower levels. If it is severe enough it effects the brain and causes irreversible damage and restructuring in the brain. Very dangerous because it has no smell and is invisible. It happens with high temperature fires that aren't getting enough oxygen.
Thanks for showing an actual cat instead of animation. I learned a lot.
The bounce and the cat are bed fellows, if the lean/rich bounce were more efficient then the cat would be less necessary. That oscillation is needed only because the feedback mechanisms lie on each side of the wander. BMW's new system is a more narrow channel to oscillate in. It can fire an injector several times as needed instead of just having a longer or shorter period. This means WAY more expensive and sensitive components, but better power and economy. AND a trend to anticipate.
The hole or bung is for an oxygen sensor to be in. It's threaded. I removed the oxygen sensor when removing this cat. Otherwise there would be no hole to let air in. In reality, were that hole to be open it would leak exhaust which is hot and would work upwards into the cabin area. Exhaust is an expanding gas especially in the cat. It would move out as apposed to oxygen getting in.
you can tell someone is truly smart when they sound effortlessly intelligent
Very educative vid. THANKS.
btw, tip for the kids nightmares problem, minimize their internet time, or filter content.
some games and vids out there can really mess up kids brain.
+Jeremy Hall He's telling the truth and I'm 17. If they are 6-9 it is common lol. Don't be ignorant please.
Jeremy Hall
i got nightmares playing resident evil 4 as a teenagers....PTSD...
Also, loss sensitivity to life, people, grew ignorant to personal issues, & non-responsive to activity requiring thinking process (avoidance of challenges). Think my IQ dropped...badly.
I can only imagine the nightmares you will have from real life.
+YangSword9x lol it's not just resident evil man, I think the whole world would be better if it lost most technology especially the ones that require us to stare at a screen for long periods.
loved the video lots of good practical information. try getting your kids energy out before bed, walks, playing games in the park, just because you burned energy all day at work doesn't mean they did the same.
Thanx Brian!No one can accuse you of having a ''goyisha cup''.(I hope no one else knows what that means.If they do,I'm in for a lot of ''tsuris''!)If the code pops up again I'll replace the post 02 sensor with a factory part.OY-VEY! The prices!You're knowledge is truly worth its weight in sheckles! May the blessings of the L-rd be upon you. Shep.
Love this video!!! You speak clearly, know your stuff and are not afraid to share what you hypothesize... I also sense a genuinely good person in you... Keep em coming...
Recently with 6 cars in the family, I began to act on my instincts mechanics by suggesting and trying things in connection with my mechanic's expertise. For ex. the computer showed Malfunction on cat and 2 sensors. Bought all the parts myself, but the carparts place kept sending me the US honda sensor, not the import which my Honda was... anyhow I got fed up with trying to get the right part so I cleaned the old one and Voila... it worked!
Great work Elizabeth! And thank you for the feedback!
I had issues getting the wrong cats from autozone and oreillys for my friends mercury mountaineer too. I had to take them off measure the inlet and outlet and get a pipe reducer to weld in too to make the back one fit. One of her front cats was melted and the back one was clogged. Only one worked with the temperature check being 100 degrees hotter after the cat. How did you clean your cat? I have a dodge stratus I bought to fix up and my only cat on this thing is not passing the temp test. I could smell that it wasn't working. I'm just curious on how you cleaned it. I want to flush it out with acid just to see if it will work. I tried vinegar cuz I had it layin around. Nope. I tried carburetor cleaner also. Nope. Oh and by the way I think it is the most awesome thing in the world that you have mechanical instincts. I am honored to even hear of a female that will work on cars, wow!!! That made my heart throb, seriously. Sorry if i sounded sexist or like a creep, lol.
Elizabeth Stenholt did you know you might as well get those codes when your car runs on too rich fuel mixture ? sunburn fuel causes catalytic to heat up and oxygen to read wrong readings :) your "expensive" problem could be caused by anything like spark plugs usually $5-10 each or better yet a broken intake vacuums line thats not even $5 =) find a good technician and stick to him because thats what a life is. on top of that you could demand that mechanic used a scope to verify if his finding is correct or not
Elizabeth Stenholt
Elizabeth Stenholt you should ask him out on a date since you're so mesmerized.
They are all cats. The configuration, size and placement help it pass IM. Typically when the four up front fail or burn out an owner will opt for a single big cheap one where the pipe comes into one.
My Alfa uses mechanical fuel injection that atomizes fuel at 300 psi! That's why Alfas did not use cats until 1980. Then they couldn't afford to build the complex injection pumps anymore and used the Bosch electronic system. That made cats necessary. Thanks, great vid.
Nightmare thing, that's tough. How old are your kids?
I've noticed with my own (4yrs) that he wasn't afraid of ANYTHING until he saw transformers. It seems that "bad guys" are of course inevitable but focused on WAY TOO MUCH in American culture. Take all of the skulls for example. Skulls should not be a fashion trend. My son came to me & asked if the skull on his lego man was a bad guy... that sh!t looked pretty evil to me so I told him it was. We sanded it off & solved that problem.
Sanding subconscious manifestations from your dreams are a bit more difficult. Polish it over with bedtime rituals of security & maybe even a spray bottle labeled "nightmare spray" to wash away the dreams if they wake up. YOU believing it will help & reassuring your child IT WORKS will strengthen the effect.
Our ritual starts with my wife & I telling our son that we're always very proud of him & that he brings our family great honor. Then we visualize the cells in his body glowing with a golden field around them. A golden bubble of light that protects from all the bad & radiates all of his golden glowing goodness.
He's never been sick, never had an earache, no skin breaking procedures, & is one happy little man. Our own thoughts & energy can greatly affect the outcome of our offspring both for the good or the bad. Let the kids know that they are in control of their dreams & eventually they will overcome the negative force driving the nightmares.
Hope that helps
~Mike
Kids can be tough, no way around it. Just love them, and help them grow.
Kids & Nightmares: As long it has nothing to do with teething; 1.- Make sure you secure all your doors & windows and have your alarm system ON. 2.- Supper is served at 6pm & bedtime is 8pm.( =curfew). 3.-explain them what stars, galaxies, etc are and entertain them with hand shadows..teach them to count between lighting & thunder. 4.- (hardest) teach them that you're always there with them (tip: have'm feel their own heartbeat). Hope it works.
If the cat is off the car you can clean them with laundry soap and water. Scotty kilmer has a video on that. As for me- if it's that old/bad I just like to replace them.
used to make catalytic converters and shells for them at TABC in long beach,ca.
Brainsmobile you are more lucid than a Harvard Professor. Like me you are engineer, mechanic, chemist and yes, POLITICAL SCIENTIST. OIL lubricates the Worlds economy, if you mess with technology that severely increases MPG , you are marked for death. I am retired, Keep myself busy with research on improving MPG. I have improved horsepower, gotten better MPG and decreased emissions. But I keep it under my hat and stay alive. But I feel bad. I am the only car on the Sagatos PKW on Sundays.
Are your kids falling to sleep to music or TV? If so get them to stop an hour before bed time. I had a daughter that fell asleep to TV every night, nothing scary either. We randomly asked a Doc about it at a check up and this was her advice. We stopped the TV before bed time and the nightmares went away.
We used to always get em cut off in high school and run straight pipes from our trucks. I'm sure its probably punishable now by law, but those things screamed. I think it made them run better too. I miss the loud obnoxious sound of my old chevy with pipes on it. Man that thing would blow your ear drums. Good video bud.
for kids, it depends on what the nightmare is, reading 20 minutes of a story book before bed time helps, if they have a nightmare of a monster or something like that having them draw you a picture of it as they tell you about it then kind of go through it with them if they say it has scary teeth explane how it is not so scary and make them laugh about it like saying that monster dont brush or floss
If you do research on "peak oil" it suggests that we have used more than half of the worlds oil reserves. They say all the "easy oil" or the oil that is easy to get to has been depleted. Some argue and say oil dry wells when re visited produce again and are no longer dry. It could be that it's like a flashlight with dead batteries. You can turn it on and it works again.... but not for long. I take any oil news with a grain of salt.
Last time I did my smog was right after a 50 mile trip on the freeway on a 90 degree day. No wait time at the shop. Drove right on to the dyno.
Thanks for the history lesson too. Tom Ogle was NOT the last to be rubbed out for the sake of capitalism. Bringing up young kids is all about sleep maintenance, nutrition and living by example (do as I do/speak as I speak). My kids only ever cut sleep for toothache or bubble guts.
That story reminded me of the two Americans that invented the traffic light.. I can't remember their names but they were a father and son and they apparently had build an engine that ran off water.. they had witnesses that saw them fill up the car from a lake and it ran like a normal engine somehow.. They disappeared.. oh and the US government apparently just stole the the traffic light idea and they didn't get any credit for it.. I think their names were Garrett or something like that.. Then years after I read this I was hitch hiking down the east coast of Australia and got picked up by a farmer who had a genius son, he was about to start university at age 11.. he said to his father that he could get the lawn mower to run off water and his dad gave him the lawn mower.. I never heard what happened to him but probably disappeared too.. oil just makes too many people fat to have these water engines running around all over the place
Amen to that. I'm glad my truck is pre 2010 because it's cat and DEF free and it's paid off!
Yes. Fuel injection makes a big difference as does whether or not either vehicle is warmed up. Good question!
Such great info. Really appreciate you taking the trouble to make it understandable for the rest of us. Great job.
tipperary links u.
The meow in the beginning caught me off guard. NASCAR! Lmao. Very informative video by the way!
My 1997 BMW 328i has an air pump by the exhaust manifold that forces air (oxygen) into the exhaust and heats of the Cats quicker. You can actually feel the exhaust heat up quicker with your hand as soon as you start the car. Pretty neat system.
Haha! You got a thumbs up for the cat joke! Cool video too!

512kjt i plus oned as well.......because of that.
Thanks for the information. My exhaust basically rusted out right in front of the cat, and ended up dragging on the highway. I was told I could just put on a straight pipe and get away with it. After watching your video, why would I skip out on replacing my cat? This video was really everything I needed to know.
I'm still contemplating your cool oxbow lake analogy, and now you've posted another winner.
One of the interesting things I recently learned (from scannerdanner) is that the cat requires instantaneously changing ratios, to be sure there is enough CO to allow it to work properly. CO is actually used to make the cat do it's thing, so O2 sensor signals have to cause a lean/rich bounce.
This video is extremely relevant to the movie called GasHole. You should check it out. There was a 1948 Buick Roadmaster that weighed as much as a Hummer H3 and it got 100 MPG. If they had the technology in the 50's to get 100 MPG, imagine what today's lightweight cars could get...
This dude is cool in my book. Being a dad and putting out great videos ain't no ez task I love all of his informative tips and tricks great work bro.
My dogs went insane when you meowed.
Hi Brian,it's Shep.After replacing both 02 sensors w/factory units the po420 code still came back.Auto Zone replaced the Walker cat for me(I had to install it. Thank G-d it's a bolt on unit!),but it has a 5 year warranty.The light is GONE! Thanx for your help and guidance. To say I'm a regular customer is an under statement!When I walk into my local (Ocala Fla) Auto Zone it's like Norm Peterson walking into Cheers!If they served beer I'd never leave!But then I'd never get any work done!Le'chiem!
thank you for the complete run down. I had no idea what the insides looked like.
You'd have further evidence if that were the case- like oil in the intake tube, oily air filter, blue smoke from the tail pipe etc. I'm not saying that's NOT the problem ( I'm not there to check or observe first hand).
You would make a great college lecturer, easy to listen to and a bit of fun as well
I had a 1984 F 150 that was equipped with concepts from his patents that I got early from a guy in Australia. It helped, but got nowhere near what he claimed. Again, my design wasn't the same. I did things only under hood and not in the fuel tank as well.
Interesting.... you're welcome. My dad has a mercruiser that needs new u-joints and bellows. I've got it all torn down and have the parts, but have been too busy to complete it.
I know. I've built many contraptions as contracts for investors etc. The principles are correct, but the details in the patents are incomplete if they do work at best. BMW's new design injectors are a good step in the right direction.
Hello - just watched your vid on catalytlc convertors, and I have to say, it was one of the best, educational videos on the subject. Hats off to you sir, you made it all very easy to understand!
Thanks Mike!
If not the best, one of the best informative videos on RUclips, in my opinion, thank you. And I feel your pain... Never been a good sleeper myself and have relied on cat naps most of my life. As for the kids, possibly, one of the things that could help is food: type? Quantity? How late they eat? Sugar.... My six year old grandson seems to be affected by red die in soft drinks. Hope you get some sleep soon.
That problem can drive you to mishegas! The Bosch O2 sensors are great in most cars, but are schlock in a GM truck. You have to use a GM one after the Cat for the GM computer to be happy.
Not really. It only does for about a minute or two on start up. It actually helps oxidize the residual fuel because the engine is rich when you first start it. And there is no more oxygen in the exhaust. So the air pump oxidizes the fuel in a process called after burning the exothermic reaction helps to heat up the cat.
+John Smith , Pagan Sunburn suggested checking for vacuum leaks and i agree but also inspect all of your electrical connections as well. it may sound strange to you but more often than not a driveability issue can be traced straight to the most basic and often skipped step in diagnostics. as far as using spray solvents to check for vacuum leaks, theres another way. use a small propane bottle just barely opened and at the same places. if your idle increase youve found a leak. some vacuum tees are temperature switched and wont allow vacuum thru certain hoses on a cool engine, and spraying brake kleen or carb cleaner on a hot engine is as smart smoking around an open gas tank. this is why i advocate using popane to check for vac leaks
briansmobile1, great vid as per your usual. id like to add if i may, some personal observations from 30 years of repairing cars. the threaded bung on the side of the converter has been around a very long time. it started out as a way to inject fresh air into the converter to burn off unburned hydrocarbons via an air pump on the front of the engine [remember fords smog pumps that always failed?]. even though i have never seen an O2 sensor in that spot, it doesnt mean that its never been done. keep up the good work
I know ford and mazda put them in all kinds of applications in the intake manifold. Honda does them too.
MY MIND HAS JUST BEEN BLOWN!! your video was good but what got me was "TOM OGLE". i never heard of him before and am just after reading a massive page of stuff on him.. i really want to do this with a lawnmower!!!
thanks for educating!!
Welcome to being a dad! You help deal with the creepy crawlies and eight legged beasties and things that go bump in the night. Then you get some sleep after they grow up until you have grandkids and mom or dad asks you what you did.
You bet. You can get his patent now. It's public domain now that it's been 50 years.
nice job for the internals of what a cat looks like inside
They say cats help get rid of the hydrocarbons. Hydrocarbons are just a fancy name for unburned fuel. Why they don't call it unburned fuel? My guess is people would get pissed off if they found out they were sending 40% of their fuel out the tail pipe unburned. On vapor carbs. If you burn straight stiochiometric mixture, it would be too hot for your engine. They use extra gas as a coolant to keep from melting your aluminum pistons. If you look at water injection, that essentially means you lean your engine to stiochiometric and then inject water into your cylinder to cool it. Very cool concept, i just don't have the money or time right now to play around with it.
Great job Brian! Your amongst the best on the Tube. My wife and I have 4 kids of or own and have had 70 foster kids over 7 years. I was so spoiled bc she dealt with all the difficult things like diapers, nightmares (same thing to me). Anyway I see a lot of advise here about limiting "electronic time". No easy task but it really helps. Keep the vids coming, please know they are appreciated. Really wished I was with you and your bro diving!!!! That was beautiful on many levels.
Take care
If your kids are having nightmares, it may be a sign of spiritual attacks. If you're a Christian, I advise you to pray with them mornings and nights (about 10 mins each). If you're not a Christian, I encourage you to accept Jesus as your Lord and personal Savior. Thanks for the nice video-- very informative. I gave you a thumb up.
I first read your user name as BRAINSmobile and it would be well deserved. You sir have got me to understand that I most likely have a vacuum problem on my car and probably nothing else. Thank you for this incredibly informative video. Really, thank you so much!
Awesome Video! ...reminds me of my old Vocational - Trade School days. Its nice when someone can actually SHOW you exactly what it is, whats in it, what it does, and so on. Thoroughly too! Thank YOU
Welcome Kyle!
Ya my car had the honeycomb style for the primary cat on the manifold and it go cloged wen we pulled the motor to replace the clutch we beat out the honeycomb out and it runs great now and still passes California smog regulations
That's the most educated explanations of cats and other things surrounding the area of them. Wow thanks that was cool.
I got about 400 gramms of that golden glitter out of only one cat.
This can't be all Platinum.
Can someone please tell me what that golden glitter/powder really is?
Did you sniff it? If not send it my way.
On my Hemi Magnum I started getting the engine light and it would shut down. Sometimes it would run like crap right before that. 165,000 miles and that was the first time the engine even had a hiccup. I did park on soft turf and ended up getting stuck and MAYBE got some mud on the catalytic converters. Or MAYBE the O2 sensors got messed up. I call BS on both, because the O2 sensors are not in a place where they would get hit by a high center situation. It wasn’t sitting that low. But couldn’t come up with any other reason for either to be damaged. I also have a bumper to bumper lifetime extended Chrysler warranty. So I take it in. Mind you this car is maintained. New spark plugs at 100,000 miles even though it ran fine. Injector clean just after, just cause. Everything but wear items is covered. So the dealership tells me I need new catalytic converters, new plugs, and new coils. The coils were covered,so I didn’t care. Plugs were expensive (a wear item) enough that I wanted to do them myself but I caved, even though I really didn’t believe they were bad OR the coils. The O2 sensors were totally believable, and matched the symptoms and the OBD codes. The car ran smooth and strong until every once in a while, mostly in stop and go traffic, it would run rough for a few seconds and shut off. Then it would start right back up again and run like a champ as if nothing had ever happened. I always though ignition coils either worked or didn’t. Why would it run so well most of the time only to shut off on random occasions? The O2 sensors were also covered. But the ONLY major component NOT covered is the catalytic converter. Of course. $2000. I believed the O2 sensors could be bad, and even maybe the coils. They said a rich condition could quickly ruin the catalytic converters. An engine misfire, maybe caused by the plugs, coils, or O2 sensor, could have ruined the CCs. But I think I got defrauded. I asked the tech why it would run great until suddenly shutting off, then fire right back up like nothing ever happened. He said it was because when the catalyst heats, it swells enough to at some point cause blockage, and then when the engine shuts off, the catalyst shrinks very quickly, enabling smooth running again. So the big a question is, has anyone EVER HEARD OF CATALYST SWELLING AND SHRINKING THAT rapidly? And so much as in size difference? If clogged cats make a car sluggish, always, every time, there is no way they were clogged. It ran great. And bad spark plugs won’t shut the car down, then immediately let it run great, and then shut down again at any random time, 5min or 2 days later, and under varying conditions. I do understand coils can be weak or not in good shape and hurt performance and mileage. But the car got normal mileage and ran as strong as it ever had. Exhaust flow out of tailpipe seemed the same as always, and I even found a video I had made of the exhaust sound at the tailpipes when the car was new, and compared the two and they sounded identical. Opinions? The swelling thing seemed like a stretch, but I was told that if I did t do the cats now that later on if something failed because of the bad cats that any warranty work related to that would be voided. I felt like I was pressured into it because they felt like they needed to actually get me to pay some real money. Seems like they are trying to frustrate me out of the vehicle. I even asked them point blank and they laughed and said no. I’ll get over paying for the plugs, but I think they ripped me off with the cats. And guess what? A similar problem is back and they can’t fix it, yet. They are playing dumb to get me to give up on the car.
What do y’all think about the claim of swelling and shrinking with the cats?
Hey thanks for this vid! I know it's old but I'm just getting into this stuff. I pray that your kids have peace at night and that you get rest!
My cat finds the first 5 seconds extremely informative.
Hey Brian, it's Shep again. I did what you said and replaced the rear 02 sensor (s10 2.2) with GM unit . I also installed a set of iridium plugs.The good news, MPG and performance improved! The bad news po420 code still keeps coming back. As I said ,no leaks (vacuum or exhaust) found. Ft 02 is a Bosch -rear 02 is AC Delco-cat is a Walker. The truck runs great and this is not a major concern, but it still bugs me and I would like to correct it. Se Ya! and G-d bless.
very informative, thank you sir. As for the "sleepless nights" I'm afraid I can not help you there. Ear plugs, the soft spongy ones. or as you had said, sleep in the camper. "Out of sight, Out of mind". That should help....Maybe?!
god bless Tom Ogle! didn't he get like 130 miles a gallon in a 60's cruiser? my first project ever was a '79 bronco. it would go 40 mph uphill and got 8 mpg. $2200 later, I put in a clean basic simple powertrain and threw away a tote full of hoses pumps evap canisters. It would get 20-22mpg, hit 120mph...HARD
If you have a pre 1996 model vehicle with throttle body injection you could run cleaner and longer with a bubbler setup to your intake. California got this contraption passed because LA is in a valley and they smogged out, unless the winds worked in their favor.
I see. You are right, nothing out of the tailpipe. Whatever it is, it is minor because I am allowed 33 max HC and I am testing with 34 and 35. Avg is 4 I believe. Really frustrating. Thanks for the help Brian!
Brian, love your vids, but wanted to mention that the Tom Ogle 100mpg car thing is one of many "magic mileage" stories that center on an inventor coming up with something so incredibly efficient that someone offs them to keep it under wraps. The presumed killers in these stories tend to range from oil company to auto manufacturers to rival inventors, but they all have one thing in common; the patent is out there but the touted mileage has never been objectively proven.
No worries. I understand COMPLETELY. I'm always making grammatical errors in my English.
I like the way he is talking to the cam makes me feel like i am there lol
How this guy know this much? I am a certified auto mechanic, went to mechanic school to become a mechanic, and I read offten mechanic articles and I don't know this much.
Peter Mec Mechanical engineer/Ruffneck here this stuff sounds pretty obvious to me. You can learn everthing on youtube lol and its pretty obvious that you let your car warm up to pass emisions for a reason.
Interesting story about tom ogle, now i'm curious if he was murdered by the gas company that offered to buy his creation. Thanks for mentioning his name, now im going to read more about him.
I didn't know I would actually learn something watching this video. I'm subscribing.
awww so cute the beginning with the meow
Ty for that Tom Ogle name drop. Very needed information.
I watch this and it remind me of all the great teachers I have had in my live. You are just a natural showman and the video is superb! I have been trolling FB for a while and this is the first time I feel that I have complete grasp on this subject matter: so THANK YOU!
Life is too short to be serious all the time. I study hard and long, but you have to balance that with some play time and humor too. = )
Probably HC's from a misfire or rich condition from a worn oxygen sensor etc.
What I always wondered after looking at a chunk of it was how they make the honeycomb lattice so perfectly with such thin walls- wouldn't think it was through some extrusion process, but how else could it be done?
Good to see a smart mechanic.
lol I'd just do a muffler on that one. On a V6 or V8 the cat back can help flow, but I haven't seen it do the same on a four cylinder.
I could drink a beer and smoke a doobie with this guy and just sit around and talk shit all day long.
great explanation about catalytic converter and corresponding mechanisms!
