Why the Toyota 2ZR Engine was a Failure

[@god_of_negativity9297]

EGR-System does not reburn the exhaust gas contrary to popular belief. Instead the exhaust gas is being rerouted back into the cylinders through the intake ports and it mixes with the intake air taking out some of the oxygen being sucked in, through which the combustion temperature is being lowered and ultimately the NOx emissions are being lowered. Also the Atkinson cycle engine does not reuse the exhaust gas, but it rather lets the intake valves open for a lot longer even though the pistons are already in the compression stroke, this allows for the engine to reach higher expansion ratio during the combustion from the much lower dynamic compression ratio which in term allows for higher efficiency. Those engines usually have a very high mechanical compression ratio for a petrol engine, but of course it is lowered through the intake valve timing. Either way, your videos are very interesting, keep up the good work. 😁

[@GLC-1979]

circular logic and no one is impressed with your copy/paste wikipedia definitions.

[@joskd8491]

the headgasket problems are caused by either a failing electric waterpump (I replaced mine while it was still in good condition at 230k km's), or a clogged EGR and intakemanifold. Because of this not every cilinders gets the same amount of fresh air mixed with exhaust gasses from the EGR. This causes the 'death rattle'. An important factor is clogging up the EGR is oilconsumption. An oilburning engine produces a lot more carbon, clogging up the EGR and intakemanifold fast. As a preventative matter I change my oil every 10k km's and every 80k km's I clean the EGR and intakemanifold. It's quite a job but for me it pays off. Mine has 236k km's now and burns no oil. With this extra service and maintenance it's a very reliable and durable engine. I think the first Prius's form 2009 - 2013 have the oilburning problems because of the tiny oilcontrolrings. From 2013 they don't burn oil anymore (so I'm told)

[@speedkar99]

Awesome. How exactly are you cleaning the intake manifold? Scrubbing it with a toothbrush?

[@one_mega_ohm9139]

While those things certainly exacerbate the issue, the main problem is that the head gasket itself is complete garbage. Single layer, with a crappy coating. Even with water pump and EGR maintenance I bet yours blows by 370k km. They all do eventually. If they used multi layer steel from the get-go then I doubt it would have been an issue.

[@joskd8491]

@@speedkar99 I'm using ovencleaner. It works very well. spray it, wait a while, and spray it again and again. Every now and then flush it with water, let dirty black water out, dry it and spray again. In a day or so, it's clean like new. Both intakemanifold and EGR.

[@joskd8491]

@@one_mega_ohm9139 I don't know, but I'm sure you're right. If it blows, it blows. But if it happens I replace it with an upgradet one like you say. Do these engines have a worse headgasket than the 1,8 engines used in the Corolla?

[@kgahlisomatlalakm]

​​@@joskd8491 I'd also like to know, I have a 2014 1ZR 1.6 corolla that I use as an uber car in South Africa with 432k km, bought it at 56k km, no major issues, just the alternator bearing gave out at around 280k, my local toyota dealership wanted to replace the alternator for $400, so I bought a bearing for $30 at an auto electric shop, still going strong, no oil burning issues, engine still pulls strong. The cvt transmission is still as smooth as new, I change the CVT fluid every 80k km.

[@justinatmidi]

Ikr toyota set the bar so high almost any major type of maintenance is seen as a failure

[@craigiefconcert6493]

Everything looked pretty much brand new in that engine. I guess there’s probably a different set of pistons available due to the technical bulletin. With a ring job and a new head gasket, new valve stem seals, send the head to a machine shop to check out the seats and tolerances etc, the engine would be practically brand new. The battery is probably defunct or not much life left. Let’s say you did 7.5k km oil changes instead of the probably recommended 15k km. That is 10 changes on 150k km’s. If you do it yourself that’s about $500 using synthetic oil bought on sale. Over 300k km’s that’s $1000. These extended oil change intervals are penny wise pound foolish.

[@speedkar99]

I agree...oil changes definitely help, however if an engine has an inherit design issue it'll be bound to fail at some point. They put these low tension rings to help with fuel economy because it's a Lexus Prius.

[@michaelbezoski3096]

The truth shall set you free. In reference to the oil checking, oil replacement. Totally agree bro. Some funny quips their too. Really enjoy the human side of your videos and those explanations. Very informative. Thank you.

[@padillaxA]

I love that most problems with toyota engines are a product of use case and not design flaw. And furthermore they typically dont arise early and provide a reasonable service life before any issue. Oil rings here are unfortunate but its common across the board now in the unnecessary pursuit of that extra decimal point of efficiency

[@TheCRTman]

The 2ZR-FE in the 2011-2013 Corolla I think is an excellent engine. My 2013 has 227,000 miles so far. The 2ZR-FXE in the Prius's on the other hand.... not so good.

@speedkar99 I actually just talked to my dad and he was told that they would have charged him $2500 for the job. He had brought it in 2 weeks before the warranty was up for a complete check-up and that's when they found it.

[@James-vt2cb]

I've had two close family members with the 2ZR Prius. The 2011 had oil changes every 3k miles or 6 months, and never burned a drop of oil at 57k miles. Admittedly, that's really low mileage. It was traded to Carvana during the pandemic for an astonishing amount. The 2012 sticks closer to Toyota's recommended intervals, so they cart around big jugs of oil everywhere they go. Before they knew it was a real problem, at about 180k miles, the car displayed the "low engine oil pressure" warning. She was on the highway and decided to "get to town," and drove for another 20 or so miles! Today, 50k miles later, the thing still runs very well, and still burns oil. Despite the big design flaw, it seems that these still run forever. Perhaps that's because they can motor along on the highway with low oil pressure, who knows.

[@Erichhh]

I'm at 112,000 miles and my 2010 has never needed oil between 5k changes with synthetic 0W20. At the 5k change point it's difficult to see the oil on the dipstick because it's still so clean.

[@speedkar99]

Remember half the time these engines are off while in hybrid mode, so that mileage isn't true for that engine the way it would be on a gas only car.

[@lmb5529bml]

I have a 2012 Corolla in my family with 204500km on it. It is the 2ZR-FBE though, flex fuel for Brazil where I live. Have it since 160k km and just regular maintenance, but people take waaaay better care of cars and oil changes here in Brazil so there's that. Also, the Toyota dealership oil for this engine is 10w30 conventional. And it works fine and is completely reliable through 10k recommended oil changes and higher temperatures we see here in summer.

The engine was in really good shape for 150k. We ran an oil flush through it and change the coolant twice (there was oil in the cooling system) burned no oil!

Keep doing what you are doing... if this engine went 290k kms...(180,000 miles) and was obviously burning oil well before the HG blew.. you should have warning (oil consumption) of possible impending failure if you keep up the oil changes (3k is great) that may extend that life as another commenter says his is still perfect @ 370000 miles!

[@CJinSD1]

I ran an all makes shop in a college town for a couple of years. We had dozens of customers with Priuses. The only one that ever had an engine issue was down to being driven without oil. When I went to buy a used engine to replace it, they were literally $100 a piece. There are so many more wrecked Priuses than there are Priuses with engine problems that the engines sell for scrap prices. There is no greater proof of engine quality than that. It is the terrible engines that are expensive in the used auto parts business. Try buying a 4.7 for a Jeep, or a Subaru engine, or a Ford Triton or Ecoboost. You'll find people fighting over them, because they fail all the time and there aren't enough coming out of totaled vehicles to cover the failure rate.

[@mannys9130]

When designed properly, EGR systems do not clog up and do not cause carbon fouling. The majority of poor EGR designs have some things in common; poor PCV oil separation, small EGR port passages, and excessive oil burning. The oil mist mixes with exhaust and cokes up the intake. Small passages clog up easier than large ones. Oil burning in the cylinders makes a lot more carbon particulate right from the get-go. EGR is a great thing when executed properly. Placing an PCV oil catch can in the breather line will catch a large amount of the oil mist that would otherwise foul the intake manifold. They are easy to build DIY and very easy to install. Drain it twice every OCI and you're good to go. With today's DI engines requiring walnut blasting every 50-100k miles anyway, it's not a huge conundrum to clean the intake of EGR particulate while it's off the engine. I agree that the reduction in NOx, CO, and unburned hydrocarbons is a benefit well worth the slight complications that may arise. 🤷🏼‍♂️

On a spark ignited engine the EGR also saves fuel by reducing pumping work at part load.

can definitely agree... people are stupid!

[@speedkar99]

In addition to the engine defect it sure does add up

Toyota need to fix ring desing lol, they fucjing love to burn oil

Nice April fools joke! Saying "zee" instead of "zed" was hilarious!

@@speedkar99 I'm still working on completing mine. I got to "N" and ended up saying "NO" to the rest of it.

Most new cars don’t come with a dip stick

Just the one behind the wheel???

[@speedkar99]

Sad. Not only does it indicate oil level, but also the oil quality.
