Here's why Toyota Engines Fail

In this video we teardown Toyota’s famous 2.4L 2AZ-FE 4 cylinder engine to see what’s inside and how it works. It features dual overhead camshafts with variable valve timing on the intake side, port injection, an all-aluminum construction, timing chain and balance shaft. However, these engines suffered from two major flaws that you should look out for if shopping for one of the many vehicles (Camry, Rav4, Scion tC, Corolla, Matrix, etc) that these engines were offered in.
The first common trait is that these engines burn excessive oil. They were redesigned for 2007 and burned even more oil due to clogged oil control rings and oil return holes that were too small in the piston head. Toyota addressed this with a new piston design (along with an engine rebuild) if the engine consumed too much oil.
The second major flaw affecting earlier engines was the rear three head bolts were not threaded down enough causing them to strip out. This would lead to a loss of compression, coolant leak, overheating, eventually causing warping of the head. Helicoil kits exist in the aftermarket to correct this issue.
The engine in this video is from a 2008 Toyota Camry that suffered significant oil loss. The connecting rod bearings overheated and seized up and was completely destroyed and missing upon disassembly. The metal particles traveled through the lubrication system and scored up other bearing surfaces of the balance shaft, connecting rods, main bearings and camshafts throughout.

I tried watching someone else's engine teardown video. He started by removing the spark plugs. Three minutes later, he was STILL REMOVING SPARK PLUGS. I had to stop there, the video was 30minutes long. I APPRECIATE YOU!

[@dr4g1116]

Depending on the year, these motors had a TSB for the oil control rings clogging, causing oil burning. That's likely what happened to this motor. Prior owner probably didn't ever check the oil.

[@dale116dot7]

I’ve seen this type of engine switch from ‘normal’ to ‘burning oil’ rapidly. Even if you check the oil every day and it’s fine, then one day it’ll drink a couple of litres of oil in a one or two hour drive.

[@dabigboom8140]

@@dale116dot7 i have a 2002 corolla that has that issue, working on getting the engine out to hopefully tear it down and fix it

[@dale116dot7]

@@dabigboom8140 Someone I know had a mid-2000s RAV4 and the oil was topped up before a two hour drive. Halfway through the drive (one hour) the oil pressure lamp came on, she pulled to the side of the road and filled it up again. Yet it drove for months with just a little higher than normal consumption. The local dealer would monitor the oil use but never believed that the oil consumption could switch on and off like that, even with new crankcase ventilation parts. In the end, the ECM went into the unintended acceleration mode once and she got rid of it after that. It wasn’t a floor mat or anything. I think that the diagnostic for the pedal is not fast enough and the remedial action that the software did was not adequate for avoiding low speed collisions. But my day job is actually writing ECM software.

[@nampam3945]

Brilliant work. Great Channel. No stupid music, just pure information given at speed. The 2.4 litre 2AZ has the same block and cooling system as the smaller 2.0 litre 1AZ, but with a longer stroke. 2AZ-FE burns more fuel so most problems are from excess heat in the pistons. Efforts to improve cooling occurred in 2007: the squirters were introduced to cool the pistons, the plastic water jacket block insert is intended to direct water flow to the upper piston sleeve to improve cooling around the combustion zone. Oil has to be changed regularly and a keen eye for the coolant level is needed.

[@67NewEngland]

I have this engine in a 2008 RAV4 and it was consuming oil which I noticed just before the warranty expired. My local Toyota dealer did an oil consumption test which it failed so they did a short block replacement at no cost to me. Still have the RAV4 and it's used every day.

My brother‘s 2004 RAV4 has this engine. He’s a college student but he drives a lot. His engine runs amazing and doesn’t burn a single drop of oil between oil changes. While my truck was down for a while, he let me use it. It is the smoothest running engine I’ve ever seen. Plus, his RAV4 is a rare one because it has a 5 speed standard transmission. Still have yet to see another one like it. I think that car is going to last a really long time. Quickly approaching 200,000 miles

[@DaddyBear1971]

Toyota said the main reason the plastic baffle in the water jacket was to reduce sound - specifically gurgling sounds. They were clearly concerned about engine noise. When I bought my 2004 RAV4 with this engine, 4 cylinder engines had a bad reputation of being obnoxiously loud. They wanted it to be less noisy than the competition. I respectfully disagree that the engine should be avoided. It lasted me 16 years without any engine problems. I had other minor problems with the car in its last couple of years, but nothing with the engine. I did regular oil changes. It never burned noticeable amounts of oil. I guess I had a good one. This engine has long been discontinued. Thank you for the video.

[@pjay3028]

Another fantastic video, thanks. After watching many of your videos I find it absolutely incredible that the manufacturers make fundamental mistakes with either the design or specification of basically simple, but critical, components in their engines, which then lead to catastrophic failure. With the combined knowledge of the designers and engineers from all the car manufacturers it MUST be possible to create an engine that would be totally reliable and affordable, whilst delivering all the power, economy and refinement necessary for a mass produced car. I reckon speedkar could find real examples of every individual component in an engine, that clearly work totally reliably, so combining all these into a single engine would mean it was completely trouble free, subject to basic maintenance. So WHY don't manufacturers ever achieve that.

[@jeremymurphy7320]

A few weeks ago, I decided to to piston soaks with Seaform and Marvel Mystery Oil. I poured a quart of MMO in the crankcase (i drained down to 1 qt lower b4 added) and drove it for 30 minutes with high Rev. After that, I drained the oil and kept the oil drain plug open. I removed the spark plugs and soaked the pistons with Seafoam for 24 hours. During the soaked time, there was dark liquid drained out the oil plug hole so I knew the soak was really cleaning. I soaked another 12 hours with MMO. Afterwards, I removed all the left over MMO with a turkey baster and an extension hose. I also wiped it so there would be no more MMO on top of the pistons because I knew it would smoke badly if there was MMO on top of the pistons. I put back everything and poured in new oil and it smoked very little for 5 minutes. I took a drive and boy it felt very responsive. I only put in 100 miles and the oil level stayed at the same place. I will have to wait for a while to see if that cleared out the piston ring holes and helped reduce burning oil. I saw one of the guy on YT used Berryman B12 to soaked and it ended up caused a knocking on his 2azfe. I think the B12 is too strong.

I drive a 2000 Camry with the 2.2 L that was unfairly known for sledging up. Not only does my Camry still have her original engine but that engine now has 452K miles on it. The biggest problem with these cars are that they were trouble free to a fault. Even when poorly-maintained they still reliably shuttle their owners around. When I bought my Camry (10/99) knew I was the epitome of the dumb college kid. I somehow allowed Toyota sales shark to convince me to buy a car I couldn't afford. By the time the new car Afterglow or off I realized I had done something stupid. After telling my dad of all the mean things the Toyota guy head down to me all my dad said was " Son that fancy new car better last you 200k just to break even". Being the stubborn Cubano I am I made sure the car would last me at least twice that so I took the advice of anyone who wanted to give it. The piece of advice that I credit for my high mileage but still running perfectly what's the advice given to me by an old Cuban guy it's Sears Auto in Pompano Square. He told me that oil is cheap but engines are expensive. When I asked him what he meant by that he showed me another customers Prevea van that was in for an oil change. He said the van head over 300K miles and we still running perfectly. He then directed me to the oil pan holding the old oil he just emptied out of it he dipped a paper towel into it and then another paper towel into some fresh oil he had. They both were almost The Identical color with one being slightly darker than the other. He said to never listen to Toyota when they tell you to change your oil every seven or 10K miles but to change it every 5 or 6 k and NO further! He also said that most mechanics use cheap paper oil filters into always insist on a premium one which usually only costs like $4 more. I change my oil every 5.5 k miles and my engine doesn't burn or leak any oil between changes. Now I work in auto finance and can honestly Drive almost any new car I want within reason but the reason I keep driving my Camry is cuz she represents the point in my life when I realized it was time to grow up even though I was kind of a wigger which would explain the body kits and spoilers she has sported over the years and have all been removed now. These people that buy like a Camry or a Corolla buy them because of their reputations for being Bulletproof but these people think they're literally Bulletproof. Especially by the 3rd or 4th boners.

Amazing Knowledge of the Subject

[@craigiefconcert6493]

I have a 2006 Camry that’s been in the family since new. 127k km’s. It has only been winter driven once. I thought it would last me many more years but I learned about the oil burning issue and the head bolt issue last year and now I’m not so sure. I always use synthetic oil and I change it once per year at about 5k km’s. it doesn’t use oil and runs well so I’m hopeful if I treat it well and check the fluids often I’ll be ok. I’m a bit freaked out about the head bolts issue because there’s nothing I can really do about that.

You should be able to look up the part number on Toyota by looking at something specific like the piston. On their website they'll have an exploded diagram of all the parts in the area. It's great when you want to find a specific replacement for a bolt/screw/nut that you lost.

[@jakeb4962]

There is no "standard" but the conrod cap screws are typically 12 point (triple square, as opposed to the double hex speedkar points out for the head screws). 12mm fine pitch is a pretty common size but again there is not a standard that all engines follow.

[@20alphabet]

Yes, someone knows.

[@billclinton6040]

As an owner of a 2005 2AZ-FE 4-cyl with just over 200k miles, I can proudly say that the engine still purrs. I attribute its longevity to the fact that I swapped the factory oil at 1,000 miles with Mobil 1 fully synthetic and have used that ever since. I do all my own spill and fills. If I were to guess, the reason I don't have the oil burning problems described here is that Mobil1 fully synthetic does not gum up and retains viscosity much better than conventional oils as well as contains detergents that prevent the build up of sludge. In fact, it wouldn't surprise me if this engine had another 100k miles in it, but like speedkar says, the typical owner of one of these used them like an appliance. So using fully synthetic probably seems dumb until you total a Camry, but if you source all your spill and fill needs at your local Wally World, it is just smart.

You should take apart the 5sfe engine from the 95-01 camry. I've had 2 of them and one threw a rod due to weak connecting rod bolts. Apparently it's a notorious problem with those engines. People say they're reliable, yet the one I had had ZERO sludge or anything. It first started sounding like a valve tick which progressed to a light tapping sound around 2k rpm, then while driving on the highway, the oil pressure light came on and started knocking like crazy and it threw #2 rod which broke the front engine mount and oil filter. Yes it ripped the filter off. Crazy.

[@Sky_god1]

PCV valve is to take out the gases that are at the bottom of the engine that bypassed the piston rings. And return it to the combustion chamber to be burned. If this fails and is stuck closed, it will burn the oil because the gases are mixing with the oil. Its probably the top cause for engines to fail. When I work on cars I always check it for people and replace it and just charge them for the part because they are usually not hard to change.

[@mikefoehr235]

Either lack of oil or too thin of an oil. I use a 5w 40 in mine with 200k miles for summer time, and a 10w 30 for winter. Never seemed to have an issue with oil consumption doing it that way.

[@pliedtka]

5w-40 for warmer places is something what I use instead 5w-30. However, even German engines don't use the usual 5w-40, but more in 0w-40, 5w-30 grade. For engines 'requiring' 5(0)w-20, 0w-30 seems like good compromise.

[@Infinitebreak97]

I was lucky enough to have my engine serviced based off the service bulletin/extended warranty back in 2016. One thing that does concern me is that there was another video that inspected the new pistons and rings issued for service and they pointed out that it was not really redeisgned but just a direct replacement of the existing part. This means that it is bound to burn oil again? I am just going to hope it wont burn oil in the future. Still doing fine right now.

[@speedkar99]

Well if it's nthe same part it might develop the same issue after alot of miles. There were revised piston heads to fix it.

[@nampam3945]

The new pistons are not different, you'd get the same effect cleaning the old oil rings. It just re-sets the engine back to the beginning point. If you change the oil on schedule you should be OK. For Toyota, it just kicked the can down the road so the engine now outlasts the body. The "revised" pistons are not really different (YT was car care nut).
