I took a garden hose and rinse it in the opposite direction and to this day two years later, she still driving it I would imagine the cat is plugging up again. But God bless her.

I'm always looking for techniques for making the call. I like the theory of a blanket of brown dust being blown out. I've had a chunk sit in front of the exit then by turning it off and bumping the cat it fell off the exit and it worked but the inlet looks ok. This cat had a two part cat and the back part failed. This was a fun one. I would be interested in what caused it which is probably the oil or fuel imbalance. I usually get a little rattle by hitting it

[@martinrubenstein7943]

Paul, Is the driver using the correct engine oil to top up? I’m wondering if they’re using a non-spec oil that’s not low SAPS? Would be interesting to know why some modern engines do burn colossal amounts of oil and it’s considered normal! Always good to see a genuine ScannerDanner Studios case study, not that there’s anything wrong at all with Tommy’s or Mario’s.

[@Google_Is_Evil]

They burn oil because of low pressure super thin piston rings and inadequate oil scraper rings. These are in there for fuel economy and work great for 99% of the cars during the homologation period of the prototype of the car. Lately manufacturers have come back from doing it this extreme because they had too many warranty cases and class action suits. Not sure about environmental fines, but I would not be surprised if they got those as well. It is not normal at all, but that does not mean it is not super common unfortunately.

[@KStewart-th4sk]

@@Google_Is_Evil Total fault of the EPA and auto engineers just trying to meet the ridiculous goals of the EPA. Meanwhile the customers buying these autos are the victims, paying for the fiasco created by the EPA in the first place.

[@jfmotorsportsrosas7665]

It’s crazy. It happened with me. Looks like a replay. It was. Kia as well but Creta model. After rev up without o2 sensor it went to normal operation.

[@mrblonde2013]

Same here, low power condition due to a restricted exhaust on a bmw/mini(proved with in cylinder measurement) after removing O2 and dropping cat, problem was gone. Reinstalled everything and car was perfect...borescope cat, no issues observed. Let car go back to customer.

[@rhkips]

That is absolutely insane! Just one of those flukes of statistics, you caught it right before a catastrophic failure, and everything lined up just right to present like a catastrophic failure! I had a 2020 Hyundai last week that was in a body shop for about a month. Customer took it back, left the lot, check engine light came on. Misfire codes! The vehicle was right on the threshhold of carbon build up (GDI engine) to where it would have developed the misfire codes anyway, but being in the body shop for a month, super-short trips from bay to bay, in and out of the lot over and over again pushed it over the edge, and now the shop is "responsible" for it. It sucks for the shop, but also, they immediately took responsibility and are working with a local mechanic to rectify the issue, while also providing a rental car for the customer. :)

[@KStewart-th4sk]

That kind of situation really irks me where a shop is held liable for something that was already failing. What if a rod went thru the block, new engine too? The shop should not be liable for it as far as i am concerned.

[@rhkips]

@@KStewart-th4sk Agreed, however in this case, it wasn't the shop being held liable, it was the shop voluntarily electing to take care of their customer. Keep in mind also, that body shops get held to a different standard than mechanical shops. There's an expectation (or in some cases a contractual obligation) that they return the vehicle to the condition it was in prior to the collision, and that often includes degredations and failures resulting from time spent at the body shop. Quite often, insurance will accept a supplement for these kind of contingencies, too. :)

[@thisisausername1265]

Oil ash can plug up the front of the converter matrix. Severe oil burners (kia/hyundai/subaru) are the most common.

[@calholli]

I think it's a type of venturi pump, also known as an aspirator or eductor pump. This pump operates on the principle of Bernoulli’s theorem. Take two hoses and connect them with a Y/ When air is blown through one hose, it speeds up and creates a low-pressure area. This low pressure can then draw fluid up the second hose......... So in this case, the exhaust was rushing out of that hole and that would have created vacuum and draw in air from the tailpipe and blown the screen of dirt and suit, off and out of the hole.......... That's interesting: I wonder if it would be worth creating a plug for the tail pipe with an air hose through it and push high pressure through it from the rear to try to help give it that same cleaning action.. on future cases. Might be worth a try. Edit: oh wow. lol.. You said the same thing later in the video. hahaha..

[@AKChryslertech]

I had that happen on a 2016 gmc pickup with a 5.3. I thought it was the high pressure fuel pump due to the fuel pressure being too low to start. I didnt want to call it until i was sure. Mentioned it to a buddy what i was working on, and he said pull the up stream o2 sensors and start it. Sure as shit, it started and ran fine. The upstream cat melted and filled the downstream cat causing a blockage. I was able to blow enough debris out of the o2 bung hole for it to idle normally again. Replaced the cats and it has not had a problem since.

[@sammyd7857]

The powdery substance is the metallic anti wear compounds in the oil

[@sumduma55]

Most likely zinc - zinc dialkyl dithiophosphate (ZDDP). Modern brands have reduced or eliminated zinc in the oils specifically because it forms a zinc oxide that is white at room temp and turns a yellowish brown when heated and clogs up catalytic converters when burned through the combustion chamber. They sell oil additives too that have zinc in it. These additives as far as I know are meant for older vehicles and high performance uses. Most people are completely unaware of these issues and marketing can make it sound really appealing.

[@bshymko1]

Smoke test through the tailpipe with the O2 sensor out to see if your outlet side of the cat is intact or at least reasonably serviceable?

[@ScannerDanner]

That wouldn't work or tell us anything. Remember I put the O2 back in and it drove fine, so there is flow

[@E85_STI]

Would a block throw a p0420? I’d be curious to see if throwing some cataclean straight up in there through the 02 bung instead of the fuel tank to see if it could actually break up the clog or it’s just tricking the o2 but in my Scion I get the p0420 here and there but I threw cataclean and drove it like I do my other cars and it cleaned it enough to where the code didn’t come back for 6 months. I don’t drive the car enough as it’s my beater car but still.

[@ScannerDanner]

Sometimes yes and sometimes no

[@FullFaithRepair]

It would have been cool if you could have plugged the tail pipe to see if you could of blasted some more debris out of the o2 hole...fun one thanks for sharing

[@Mark33090]

I was thinking about buying a Kia K5 GT... your friend says Kia cars burn excessive oil?? Which causes faulty cats??? Now I'm double thinking it...

[@jeffhowell3310]

Great video, I know you said +- 10% on the fuel trims are with in spec, but if you take the approach of the closer to 0% is normal and 3-4% is good with that being up at 7% short term fuel trim, would that not indicate that you have something going, but it is just not real bad yet, I do agree that cat was plugged for a GTDI. I ad one half plugged and could notice it in the power. I even had the shop run a back pressure test to verify what I was noticing. I just ask that question becuase I mess with my cars all the time and if I'm over 4% short term I know I have a issue. I am normally running around 1 -2% max.

[@ScannerDanner]

No, I would never chase a 7% total trim. Ever. And that was only a momentary period. Trends over time are more important

[@jeffhowell3310]

Interesting, but good to know, but the reason I suggested that was like right now I have a low pressure fuel issue, which has caused me alot of grief but pretty good idea what ot is, and my fuel trim has shown it as I am running 6% each way and like I said it normally is around 1-2%., not questioning you as you have the certificates and I don't for the cars and trucks, I just have it for motorcycles.

[@SeanBZA]

Spark plug compression tester will also work there with that bad a clogged cat.

[@Discretesignals]

I've seen some exhaust system pressures rapid fluctuations mess up gauges and take them out of calibration. Might be able to get a glycerin filled gauge to help slow down the needle fluctuation or if they make a check valve that can handle the heat

[@Discretesignals]

We had a customer with a theta burning oil like crazy. Even took pics of the spark plugs to show excessive oil deposits. Sent them to Kia for an oil consumption test. Kia sent them away because there was a slight leak from the valve cover. We do a valve cover gasket and send them back to Kia. As the customer is driving for the consumtion test, the cat plugs up. Kia invalidates the consumption test and tells the customer they need to replace the cat knowing full well the engine is an oil burner. Customer gave up and goes and buys another vehicle.

[@ScannerDanner]

That is ridiculous and really sucks for that customer

[@KStewart-th4sk]

I hope it wasn't another Kia. Should have put a big sign on it saying what the dealer didn't do, and park it front and center outside the dealership on the street. Some TV stations will cover stories like that to make them look like the jerks they are.

[@therealchayd]

I know it's possible to successfully backwash a DPF to flush out all the non-burnable ash, so must be conceivable that this can be done on a non-damaged, but plugged cat. There's a European company that make specialist machines that use repeated bursts of compressed air and water to blow all the crap out, works well, and saved me the cost of a new DPF!

[@rodvan-zeller6360]

I like looking at the intake air temp sensor PID when "suspecting" plugged cat, the intake air temp trends up instead of down when accelerating. Ever use that method? If so, has it worked out for you? Thank you in advance for your answer.

[@ScannerDanner]

Yes but it depends on the location of the IAT sensor. If it's part of the MAF or mounted way up in the air cleaner box, it won't help us identify this condition

[@sheerwillsurvival2064]

Another great video

[@secretsquirrel9722]

In hindsight, it would have been a great way to show the validity of an in cylinder pressure transducer. You would have started with an obvious and measurably raised pressure during the exhaust opening. Then, captured with the O2 out. All the particulate would have blown out too. Then captured the measurable improvement after woth the O2 reinstalled. Question, when you looked at the downstream data pid. Was it initially cycling like the cat efficiency was failing before you started holding revs. Indicating the cat will likely not last long after the abuse anyway? Or is that a red herring, and you would normally overlook that until you restore proper flow? P.P.S I have reverse flushed a couple of dpf's many years ago that are still going strong. There are also businesses that offer this service with pulsing pressurised solutions. Might be a viable option if you could get it off, like you said. We don't deal with rust here😅 Thanks Paul and Caleb, both interesting and entertaining!

[@ScannerDanner]

The cycling of the downstream O2 would be because basically the cat was non functioning at the time I took that capture. 1. Because it would have been cold (no flow to light it off) 2. It's restricted/contaminated so even if it was hot enough it wouldn't have been doing its job. But no, a cycling rear O2 would not be a dead giveaway because it's normal to see them cycle until the cat gets hot. But I agree the before and after in cylinder would have been awesome!

[@secretsquirrel9722]

@ScannerDanner I appreciate you taking the time to answer Paul! Of course, yes. My question assumed the cat was at an operating temperature. Which would be very hard to achieve while mostly blocked.

I've burned a quart every 1.5k in my Toyota for the last 100K miles, on the same cat. I wonder what kind of oil they used?

[@diagmind]

That’s a known issue for Kia Hyundai. Their cats are piece of garbage that start producing ceramic dust on very low mileage even when engine has no oil consumption. This dust comes into cylinders with exhaust gas back flow and guess what it does to cylinder walls, and that’s when the oil consumption starts. Have a great weekend Mr Danner😊

[@armandoesparza6103]

Don't forget the most important factor that ruined that CAT. Replacing that CAT again in a few month-I assume under warranty-, because of oil burning will be a huge headache.

[@sumduma55]

Educating the customer can help too. The powdery substance is most likely zinc oxide from oil being burned. It's a white color at room temp but turns a yellowish color when heated. I forget the Temps neccesary but it isn't real hot. Modern oils are getting rid of zinc in oils specifically because it can cause catalytic converters clogging when burned in the combustion chamber. So using the wrong type of oil can accelerate the problems from burning a little oil.

[@CajunShrek]

[@captgraybush2890]

Today must be Kia Soul day. Just had one come in with a bad upstream 02. Causing customer complaint of car wont go over 40 mph.

[@LOLpsyentist]

What other PIDs or sensor data could we directly use or calculate to determine intake manifold vacuum without a MAP. For example a ford that has a MAF/IAT but no MAP.

[@ScannerDanner]

Nothing on that set up. Why?

[@LOLpsyentist]

@ScannerDanner Just sheer curiosity more than anything. I do have a vacuum gauge but it would be cool if I could monitor something with a scan tool while driving.

[@JamesSmith-xs7sr]

IAT temp would raise if exhaust restricted, as it would try to travel back up into intake area, heating up the ait sensor. Happened last week on a 012 nissan quest. Rear bank plugged ..

[@LOLpsyentist]

I suppose if thats the case too then a volumetric efficiency analysis would be able to determine if there were a lack of airflow at a specific RPM with the MAF outputs. Assuming the MAF is accurate.

non cat related, maybe you can give me some insight on this, had a 17 yukon denali, 6.2 liter in the shop, with afm, number 4 cylinder misfire, tech found number 4 lifter collapsed, warranty company had us replace all lifters including the non afm ones, vehicle left, came back 2 hours later, cylinder 1 misfire, found cylinder 1 collapsed lifter, replaced lifter, came back the next day, cylinder 1 misfire, job was given to me to look at this time, cylinder 1 misfire, collapsed lifter again, found scored cam lobe, replaced cam and cylinder 1 lifter this time, came back again, collapsed cylinder 4 lifter again, replaced lifter so we could send this truck to wholesale (we bought the truck back), after replacement this time, truck ran like crap, no misfire current misfire counts, but cranked over like it had a dead cylinder, only code was a p0106 , the map was reading 20in at idle, after a bit of running the vehicle it started to show history misfires on cylinder 8 and 5, since i had the wheel liner already out on bank 2, did a compression test, compression was good, pulled cylinder 5 plug, did compression test, 0 compression, bore scoped cylinder, everything looked good, cylinder didnt look washed, no holes in the piston or anything, here is my head scratcher part, brought number 5 up to tdc, performed leak down test, only a 3% loss, this dont make sense on a dead hole, took the leak down tester off, hooked my compression gauge back on, now has good compression, engine cranks over normally now, put it back to a running condition, fired it up, engine ran great, cept for a mis on cylinder 4, which ended up being just a coil pack, replaced the coil pack engine runs great now??????? any ideas?

[@ScannerDanner]

😅 no. Crap parts is what is sounds like to me and another lifter/valve issue on that cylinder

[@kevinavery2518]

@@ScannerDanner thats what i think also, even though its not an afm cylinder, I'm thinking maybe a lifter stuck in the bore, and maybe doing the cylinder leak down test somehow was able to push it back down, only guess I have, ty or writing back

You have metal debris all throughout your engine from the cam lobe(s) and lifters that wore. Warranty company should pay for engine pull, full disassembly, clean of all oil galleries and replacement of all parts that have scoring of the metal debris and then reassembly of it all. Your intermittent compression problems can very well be oil galleries being plugged with swarf so your lifters stick intermittently. Cheapskate half-arsed job done so far, it needs to be done proper.

[@kevinavery2518]

@@Google_Is_Evil I can agree and disagree with your comment, the job wasnt half arsed done, it was done within the parameters that warranty will pay for, both gm and aftermarket, oil filtration should prevent that from happening, and with that said, I did cut open the oil filter after i got the truck, and no signs of metal in the oil, granted it wasnt lab tested, but this truck literally had 4 oil changes in less than 200 miles, also not to mention, the smallest oil galleys on the engine are the lifters and pushrods and those were all replaced

TSB says to mike inside lifter bore. If excess/out of round, repeat failure occurs.

[@simplemechanics246]

Only wrong oil cause something like that. They used xWxx oil but if that was not exact manufacturer reccommendation including brand name, then that is the problem. Too much metals inside the oil is bad. Sure, first thing it should not burn the oil on first place.

[@Discretesignals]

Design issue with their engines and low tension piston rings clogging up. I have not seen a Kia/Hyundai TSB stating that they would not honor a warranty because of the manufacturer of the oil used in their engines.

That smoke was probably dirt. Mud dobbers might have nested up in the intake at some point and the dirt worked it way into the cat.

Impossible unless the air filter got a hole in it

Is it just me or is scanner danner gettin beefy. dudes gonna be yoked in a year

[@asmithh2697]

SOunds like a Toyota problem! Either the Piston rings or valves are bad and fixing the Cause Should solve the oil burning problems! Replacing a Cat at 79,000.0 miles because of crappy vehicle manufacture technique's does not solve problems.

[@RobertAllen-b2t]

Who buys a Kia ?

[@ScannerDanner]

Who cares
