[@kb9oak749]

The problem isn't necessarily the engine, but all the plastic crap under the hood which inevitably gets brittle and breaks.Everything is designed to a price point. And creates hundreds of different paths to failure.

[@djaftermath4313]

Yeah, its called planned obsolescence. All parts have a life span. When you insert the plastic radiator fans and other stuff that was metal, etc. it shortens the wear and tear. The customer is left bent over with increased repair cost and frequency (model/make dependent)

[@gorkyd7912]

True, that stuff wears out especially when it's getting hot and cold over and over. Cheap stamped metal doesn't last that long either though depending on how its used and some of the plastic bits can be pretty dang long-lasting depending on formulation.

[@buckhorncortez]

Yeah..designed obsolescence is difficult. The part has to last only a specific amount of time. That's a tough calculation because of all the material choices and stress points. But, I remember being in "Designed to Fail" a 200-level course in college where we had to go through all of the calculations to show exactly when a part would fail. Then, we used to get into arguments on the job with the people who just wanted to make the best part they could with no cost consequences...

[@theantiqueactionfigure]

Plastic parts are what kills BMW's.

[@gordonparrishjr6228]

That is also true for non-turbos. Aluminum would be a far better choice than plastic.

[@sastrinidis]

The problem is that engineers also claimed cylinder deactivation wouldn't harm the engine which has been disproven and it is still used for vehicles today. Engineers are not concerned with reliability, they aim to minimize warranty work.

[@davestvwatching2408]

Engineers also expect customers to maintain their vehicles properly. Regular oil changes,(not 10K miles) filter changes and also driving their cars proper long distances so that carbon and water gets burned/boiled off. Not just 10 minutes and shut the car off.

[@sastrinidis]

@@davestvwatching2408 there is no proper maintenance for poor design. Your regular oil changes will have no effect on the carbon build up due to cylinder deactivation. My Ford had a water pump running off the engine timing chain, usually it is off the serpentine belt. That pump started leaking coolant into the oil and seized the engine. Again, there is no regular maintenance to prevent that but would have been a simple fix is now an engine replacement.

[@davestvwatching2408]

@@sastrinidis A lot of cars have either timing chain or timing belt driven water pumps. I have a 90s Honda with a timing belt water pump. Moving the water pump into the block casting allows for a smaller engine. Improves safety because you can design front end structure around the smaller engine. It's the true reason why inline 4s are the current choice. Carbon build up is helped by the driving distances vs stop and go. Why did the water pump start leaking coolant? Coolant is a maintenance issue often forgotten or ignored, admittedly the manufacturer marketing departments loved to push 100K changes but it probably should be 30K.

[@sastrinidis]

@@davestvwatching2408 there was an attempted class action lawsuit against Ford for that specific engine (3.5L V6), it failed on me at about 75k miles, so not a very high mileage car. I have since switched to Toyotas and have not had the same headaches I had with previous vehicles (Dodge transmission failed 3 times within 150k miles).

My brother is a mechanic at a Chevrolet dealer in New Jersey. He told me that they have a high amount of 2.7 turbo and 2.0 turbo repairs pertaining to broken timing guides. Around 60-100,000 miles.

[@TFLtalk]

Thank you for the feedback.

[@glow4417]

I am all for turbo engines, owned a couple myself. But a turbo engine, will never be more reliable than an naturally asperated engine. Even with the same quality engineering, for all parts, turbo engines just introduce more problems and things that can go wrong...and more maintenance needed. Electric engines and hybrids are different, because it's mainly just the battery in that configuration.

[@beexiong2995]

​​​@@glow4417turbos are not complicated at all. Also a 4 cylinder turbo has less moving parts to go wrong than a V6. A turbocharged engine adds a compressor/turbo, oil lubrication, intake plumbing, and engine calibration for boost. I put a turbocharger on a non turbo engine before and it is as simple as an exhaust header removal. It lasted a long long time given it wasnt built for it. A engine built for turbo applications are reinforced for boost and will be just as reliable if not more.

[@shadowopsairman1583]

​@@glow4417thank you for telling the truth on this matter. I think turbos need a dedicated oil pump and oil cooler to not destroy the bearings. They have them for engines, transmissions, power steering pumps, why not for turbos and super chargers?

[@terrencejones9817]

I've never seen a single mechanical issue with the 2.7L turbo , the 2.0L LTG in some of the older iterations could have piston issues. Never seen any timing chain issues with them.

[@herbwheeler4470]

Would you expect engineers to say "naw turbos aren't that good " ?😅 They're all going to be positive about their products. They might last until the end of the warranty. 😅 there no money in them to design an engine that last for 150K + miles. My thoughts are simple is better when it comes to engines.

True. But then you're complaining about lack of power when you want simple.

[@shadowopsairman1583]

@herbwheeler4470 agree that upgrading the 3.6l would have been ideal. But those I know who have it al tell me it was a dog of en engine. Sluggish and felt like something was lacking. But it's the govt forcing makers to go to these engines with regulations. In the name of this garbage climate crap and epa ratings.

[@alexsmba]

@@herbwheeler4470what? The 3.6 is pathetic. In the Colorado, 18mpg and needs to constantly operate in the lower gears and higher rpm range. It was adequate for a sedan. But used almost as much fuel in the Commodore as the V8. It’s a pathetic engine. They did the best upgrade they could. Get rid of it completely and replace it with that 2.7 I-4 turbo.

[@andyharman3022]

Andre was pretty amazed by the Ford engineer's discussion of piston cooling nozzles. Those have been standard features on heavy duty diesels since the 1970's. It has been interesting to see how gasoline engine internals have been migrating to looking like heavy duty diesels for about the last 10 years. Keystoned small ends of connecting rods, piston cooling nozzles, gallery-cooled pistons, and steel piston ring carriers were all pioneered on diesels at least 30-40 years ago.

[@timbaer8525]

I couldn’t help but notice not one of the engineers said they went the 4cyl turbo direction for ‘increased reliability’.

[@allanclark5925]

Andrey, I wish you would try to pin those engineers down on exactly what they consider the life of the truck. Are they designed to last 100,000 miles or a million miles. Do they design their trucks to last 5 years, 10 years, 20 years, or more? Many non turbo engines without cylinder deactivation will last 250,000 miles with no issues. How will the new turbo engines compare to that?

[@shadowopsairman1583]

Solution of cylinder deactivation, turn it off, once warranty is out do the valvetrain upgrade and run it as a standard engine.

[@Justmejbful]

I think the life of truck would be the average life we have come to expect so far for prior model years. They don't expect the turbos to go out before the V6 engine would

[@Dublin777]

They would lose there jobs if they told the real truth. But it's not there fault, there are people above them that control things. If it was all up to the engineer, they would be proud to build something that would be rock solid and put there name on it. I could be wrong but that's my two cents.

[@gorkyd7912]

@@Dublin777 Probably true but honestly, for all the complaining we do, the engines of new cars are pretty damn reliable. I'm usually more concerned by things like electronics going bad making all the internals a pain to deal with. Touch screens wear out or get wet.

I find that most engines [all my engines have been diesel for the last 35 years] take about 15,000 miles before they reach peak performance and fuel economy. They continue to improve from new to around that mileage and that has been very consistent for about 15 or more vehicles from a Fiat Panda to Range Rover to Land Cruiser100 to Audi Q7 to Ranger pickup truck and many more. It’s not just the engine that runs in of course, the whole transmission does also and the more complex the transmission and axles, the greater the potential for initial friction and improvement in service.

I love the 2.7 in my F150. I have the first year and was very unsure about it due to its displacement and it being new at the time until I test drove it side by side with the 5litre.

[@Euroimports]

I used to be a Honda Master Tech, now I’m a Porsche tech. I understand why they need to put in a belt for the oil pump as most new vehicles especially turbocharged vehicles helps the oil continue to run when the engine turns “auto on/off) at a stop light feature to help with fuel economy. Yes, tech will know if there is a known problems if the same make and model comes in for the same issue over and over. They may not know of how many cars are sold to fix ratio, but we do see how many of the same make and models does come in for the same issue. Manufacturers will open recalls if the problem becomes a known problem. It also falls on the tech to actually document correctly to help the manufacturers understand what and why a component failure occurs. Hope this helps

I would have loved to ask the engineer about how well reliability is measured against complicating systems (everything is electrical/computer-module dependent etc), and if it wasn't for emissions and other constraints - would he still pursue the same design and system development. Might he consider lessening some of the complication? Good interview and appreciate what the entire TFL team brings to the forum! Of note - i got rid of my 2021 F150 Lariat and bought a 2023 4Runner ORP, and to date - incredibly impressive what Toyota did with this 40 year old design/machine. I was worn out with recalls, computer reprogramming and other mechanical issues in that 14th gen Ford. It though reminds me how less is more (simple and not complicated).

[@bozartg]

My work has a 2020 XLT Ranger with the Turbo4. Very basic quad cab and it's driven by several people hard! It's my week to drive it on-call and it has 22,500 miles with absolutely no issues. I own a Tremor and the mileage is only about 3 - 4mi/Gal less than the average of this Ranger. So, for a much more comfortable truck I like my full size f150. The Turbo on the Ranger makes it move very well though and gives it a real tow capability.

The main source of oil onto the valves will still be the turbo, it’s inherent that some will come through directly onto the valves. I agree that DeXos oil is critical for coking reduction as well as primarily to reduce timing chain wear due to soot from oil combustion in the chamber.

[@jasonstephens8459]

Any system is dependent on the components functioning together . If one component fails the system fails. Sometimes it can be one o-ring in the critical location that kills the entire engine . So more components equals likely hood of more problems .

[@alexsmba]

So an electric motor is the way to go then. Or if it has to be an ICE, an inline 2 cylinder with 4 valves total (single cam).

[@gorkyd7912]

It's generally true but I've never really been disappointed by GM engineers, believe it or not. They design fine vehicles, the failures come in the manufacturing stage. So yes, more components is more to mess up in manufacturing but it's totally possible to build complex vehicles it just requires higher quality standards.

[@trobbins88]

I had an opportunity to buy a '23 Sierra Elevation with the 2.7L Turbo but I decided to go with the 5.3L V8 instead...not regretting my decision, especially when it comes to fuel mileage.

[@thomasrichmond7017]

Agree 100%. I have a '22 Elevation with the 5.3 and get just over 20 mpg hwy when I'm not in too big of a hurry. I could've gotten an SLE with the 2.7 and saved $5000 but I know I'll get that $5000 back (well, most of it anyway) when I eventually sell my truck. I typically abhor all caps, but when I go to sell my truck I'm going to write "with a NATURALLY ASPIRATED 5.3L V-8." I'll probably also add, "with no DFM." I paid too much for the truck because of the pandemic, and its value has taken a nose dive, but I'm confident it'll hold most of its current value over the next few years thanks in part to its engine. Love it.

[@JP-gw9ts]

My ‘86 toyota FACTORY TURBO 4runner had 348,000 and still running strong when I sold it. So I really depends on who makes the turbo. If toyota or denso make it’s gold, if it’s mitsubishi or hitachi probably not great. If it’s GM, ford, audi, benz, bmw, dodge, vw, volvo well good luck long term with that.

[@JarmelSingsKaraoke]

[@CurtinFortCollins]

Thanks for all of your work on bringing information to us. I have been watching since 2022 and wanting to purchase a new mid-sized truck. I currently have a reliable 2015 Jeep JKUR, so I am willing to wait a little longer. My concern is from an engineering and physics standpoint: Turbos will work an engine harder. I have a hard time understanding how you can have an engine last longer, especially with these smaller liter engines. I understand they want to get better gas mileage and emissions. I am OK with a little less mpg if the engine lasts. I could not buy a Chevy, GM or Ford because of their poorer quality and the dealer service seems less responsive. While I will be interested to see the new Toyota's reliability, I do believe that Toyota is easier to trust to address issues. I kinda want a 2024 Tacoma hybrid with the current engine (V6). Maybe upgrade the transmission. Love the changes to the body. I am seriously looking at the Nissan Frontier Pro4X with the V6.

[@gregmoessner3104]

I’m inclined that way too.

[@shettlock]

yeah im kinda hoping the nissan v6 is around in 4-5 years when I'm shopping again.

[@ryanmartinage]

@@St.IrenaeusI bought my 20’ frontier for this reason. Old body but has the new v6 and 9 speed. Completely happy with it.

[@ryanmartinage]

@@St.Irenaeus you also get the benefit of it Being largely based off the old platform so there’s inherent reliability there. Additionally, midsize trucks cooled it on the towing numbers race and Nissan is right there with everyone in a true midsize truck with reliability naked in from years of production.

[@chclayto8]

As a former machinist, I highly distrust engineers.

[@YerBoyTroy]

Highly recommend watching Pickup Truck + SUV's interview with Mike Sweers (title is Toyota's Tundra, 4Runner, Sequoia, Tacoma Chief, Interview from Japan). At 30 minutes plus you'll get a (seemingly) honest engineering perspective on the compromises between small displacement turbo, emissions and regulations. The reality is small displacement turbo is a compromise for regulatory demands to reduce emissions. This is not an improvement in reliability or engine performance. Engines are now being designed to suit regulatory demands and less so to suit the type of vehicle its being built for That being said, environmental responsibility is important but this is not the way to do it i think.

[@epicletterr4048]

I have a 2023 Tundra which I love, but somehow I don't think the Toyota serviceability checklist said "it's ok to have to separate the engine bay from the rest of the truck to access/repair the turbos."

[@jamesstephen5694]

Are naturally aspirated engines more reliable than turbo? Naturally Aspirated Vs. Turbocharged: Engine Battles » Oponeo ... This is because naturally aspirated engines last longer and are more reliable than their supercharged counterparts. Forced air engines work harder as they use higher compression and run hotter combustion chambers.

[@beexiong2995]

Like any engine, it should be engineered to handle the stock outputs of power. It's when you start modifying adding power or underengineer a component when you get problems. Take for example Honda V6 transmissions in the 2000s were trash because they were underbuilt for the V6. Turbo engines are engineered to handle more pressure like iron blocks, closed decks or iron linings in the cylinders and better cooling. A normal NA engine wont have any of those benefits and even then are not fullproof. Its all in the engineering.

[@Jaredius]

This has been common knowledge for decades, but we live in a world full of gaslighting.

That had nothing to with engineering. That was negligence. The design engineers warned them and the warning were ignored.

[@daveallen7767]

Folks need to realize with complexity comes increased maintenance & cost. For example my take trash/recycling to township drop-off pickup is a 2007 F150 with 180K miles. Still has the original shock absorbers on rear, original spring shackles & bushings (both springs replaced 1X). What will cost be to keep a truck with coil rear suspension running good for that many miles ? Many more wear points to deal with !

[@HAHA.GoodMeme]

@@daveallen7767 what? replacement coil springs are literally $100 each. From Eibach, not chinesium. A single shock tower location to worry about. Leaf springs are cheap and reliable but so are coils.

[@mdgeist472]

There are also issues from coolant leaking into cylinders because the engines run hotter. They try to add more coolant channels, which introduces weak spots. These weak spots are susceptible to failure from the higher cylinder pressure and heat.

[@beexiong2995]

Using a closed deck design fixes those issues. Problems arise when someone overboosts their stock engine past set parameters.

[@jaredelson1840]

They essentially added a built in "no maintenance" catch can system on the L3B 2.7L Turbo. My problem with that is you're just putting that fuel diluted oil back into the oil system. Fuel dilution is the #1 cause of oil breakdown. A catch can you have to empty helps get that out of the system. With these crazy high mileage oil change intervals, for long term engine health I'd still be running a catch can that needs to be emptied.

[@FastforwardrapTv205]

Watching a mechanic's review, he made it perfectly clear that if you want a turbocharged truck as a long-term vehicle, you will more than likely have to replace the turbo at some point. Basically, it's not even possible to make a turbo engine as reliable as a naturally aspirated engine. However, like most of you all, I do believe Toyota will be the one to figure SOMETHING out in regards to turbo reliability that their competitors will not. Maybe not with these first couple of years of production but 3-5 years down the line. They're just one of the kings of reliability. Still, it just doesn't seem possible to make them as reliable as natural engines

[@virajrockybhutani8367]

Recommend a video with some of the folks who have torn down these turbo truck motors and have found a bunch of problems. For me, I am not buying a gas truck with a turbo motor.

IMHO, a turbo gas truck motor is not going to get anywhere near that kind of life.

Over engineered PCV system - the oil passage will plug up once the oil gets little bit dirty, a small spring inside? Really? Springs tire, wear out, break. Can you imagine the repair cost to replace that tiny spring that probably cost less than a dollar? The labor to take the engine apart will cost you hundreds of $$$ to replace a tiny spring!! Plus, the valve disengage system is a terrible idea - uneven heat which will cause more dramatic wear and tear which means the engine will not last. Why don’t they talk about how easy or difficult its going to be replace certain parts? …and the list goes on and on. In addition, GM is not well known for using durable quality steel materials or quality control…poorly put together, etc. I would not touch these engines or any GM truck with a 10 ft pole at this stage. Can they talk about or describe the torture test they put this engine through? …deprive it of oil, run it with dirty oil, time of continuous running, purposely introduce malfunctions of certain components, etc….because subjecting the engine to extreme failures is the only way to improve the engine and make it really reliable. Video graphics looks great on the screen but it doesn’t show or explain anything about durability and longevity.

[@dougsmith7195]

Wow, the Ford guy was unprepared, the GM guy put on an very detailed informative conversation? The Toyota guy was also well prepared to answer all the questions?

[@gratefultrucker7781]

So in theory if the pcv line leading to the inducter were vented to the atmosphere one would retain positive crankcase ventilation at idle yet avoid coking the valves under boost. Hmm.

[@thetinysideoftiny7625]

I’m old enough to have lived through the first wave of the turbo fad in the mid-80’s. It did not end well. This second wave won’t be much better. Yes, technology has advanced 40 years, but you can’t change physics. Tiny turbo 4’s are going to get pounded on in truck applications and you are simply not going to see space shuttle miles out of these drivetrains. I just bought a new Nissan Frontier w it’s naturally aspirated V6 for this very reason.

Just time will tell us if any of those engines are reliable and will last long. Off course engineers will talk wonders about their creations. Imagine what would happen with the engineer if he/she said something real about their engine that isn’t good. I believe cars and trucks today are more fragile and problems prone than previous generations, simply because the excessive use of sensors. Not mention the complexity added to maintaining those vehicles.

[@romeou4965]

I expect engineers to do exhaustive testing before releasing a product. Their talk is backed by empirical data.

[@byronnlangley]

Turbo chargers themselves are not inherently the issue. The issue is relying on a turbo to produce the HP the engine should do on its own. Taking a bigger N/A engine like 5.3 or 5.0 or even smaller like 4.0 and putting a turbo on it to assist the power plant works fine. The problem is when you use a small engine like 1.3 liter 2.7 liter and throwing a high pressure turbo on it to make usable power, because the engine will be strained over it’s much shorter life span than a larger engine or a Naturally aspirated engine. Then you have to watch the heat as most of the factory turbos are oil cooled and not water cooled. Turbo engines also need to keep running at idle before the engine turns off to keep the oil from burning on the impeller bearings. Also you have to change the oil at much shorter intervals that most drivers do not do and also need a good synthetic every oil change. Because of these issues that most people do not know to do the used market is very hit or miss due to not knowing how the previous owner treated the vehicle. You have much more issues throughout the vehicle like the Hp fuel pump timing etc etc. using a small turbo engine on a small car like a Honda civic works but using it in a truck not so good

It's about being able to put a vehicle through the paces day in and day out and knowing your turbo isn't going to fail or transmission is going to fail.
