That does indeed worry me. The Ecoboost was getting all this promotion! I have a 2017 F150 with the 2.7 Ecoboost. I'm getting close to 60k. No indication of any problem....yet.
Actually the belt is stronger than a chain. I know it sounds crazy. But the belt is usually stronger than steel and being wet makes it stronger . Many high rpm Indy engines turn 18.000 rpm’s and the belt has been accepted as a strong choice. I wish they could be easily changed. But engineer friends tell me that they have taken the belt far beyond what they were. The key is to keep the belt short enough that it doesn’t deflect.
You’re absolutely right about almost every motor in this video. You’re dead wrong about Ford’s Cologne 2.8 & Essex 4.2. I’ve been a mechanic since Christ was a corporal and I have seen ZERO evidence to back up your claims regarding these engines. I bought a Capri with the 2.8 and drove it to over 150,000 miles before giving it to my neighbor’s son, who had it for years before trading it for a Mustang. And an old friend has over 200k on his 4.2 V6 powered F-150.
I agree on the Ford Cologne. Many years ago I had a '79 Mustang with that engine. There was a few issues with the car, but none of them was with the engine. it ran perfectly, although being a bit thirsty.
The Essex which gave thermal problems was the 3,0 V6. And what is problely not known in America, the Isuzu 3,0 diesel that was used in a lot of European diesels in the 2000 till 2010.
Also confused the 5.4 triton with the 4.6 2v. The 2v had the thin thread amount issue up to 2004. Slightly improved after. The 5.4 had the ugly 2 piece spark plugs that came apart and left behind the threads to extract with a special tool.
Regarding the Ford 5.4L..... you're conflating the issues of the earlier 2-valve with the later 3-valve. The 2-valve is the motor that "ejected" spark plugs, but rather than the low number of threads, the real problem is the torque specs. Ford listed the torque spec to be 11 lbs, but if they're tightened to 25 lbs, you won't see this problem. Maybe more threads would have made a difference at 11 lbs, but a quick turn of a wrench takes care of the issue. Personally, I have the 2-valve and have never launched a plug. It's the 3-valve that features 2-piece plugs that will break off in the cylinder head when attempting to remove them, and has the cam phaser issue, since it has variable valve timing that the 2-valve does not.
I agree on the 2.8 when i was growing up nearly everyone was buying eay to mid 80' Rangers some had the 4cyl,1 had the 4cyl turbo, and a few had that 2.8. Mated with a 5spd that 2.8 was impressive at the time and they beat the hell outta their trucks
Maybe my mom just got lucky, but her 32 valve north star sedan deville was bulletproof. If I had it to do over again I would’ve bought it from her. It was the ultimate shaggin wagon.
200k miles on northstar 4.6, Obviously after the bolt repair, no doubt as a small error can overshadow the durability of a great engine, if Cadillac had corrected that error in time its reliability would be impressive.
My 3000GT with the naturally aspirated 3.0 engine was reliable, and a fun car to drive. There were no issues! The timing belt however must be replaced every 60,000 miles, or it will break, bye bye engine!
The GM 2.2 4cyl and Pontiac Iron Duke are easy to fix and very dependable. The USPS Grumman Mail Truck uses the GM 2.2. The USPS would not chose a motor that was not reliable in brutal stop and go operation. 😂😂😂😂
I had a Chevy Beretta with the 2.2. Before a few H.P. adders it was gutless, but never had a single reliability issue. My Iron Duke Fiero got a rod knock 2 days after I purchased it. Didn't know the tell-tell signs when I bought it (young, poor, and naive). My experience, I'd agree the 'Iron Duke' wasn't great, but the 2.2s shouldn't be on this list. There's millions still sluggishly pushing S10s down the road today! Take that off this list, and add the Ford Powerstroke 6.0 and 6.4 diesels.
I just got a 2025 Chevy Trax with the 1.2L 3 cylinder with the wet timing belt, started feeling kind of worried, but I paid extra for the 100k mile warranty, I put about 4k miles on vehicles every 2 months, so whenever that goes and probably destroys the engine at least can be a little at ease knowing I might get more miles out of it than the first one through warranty
While I was watching the Subaru EJ25 engine part of the vid came on and the video was immediately interrupted by...... a Subaru ad. Gotta love youtube.
I remember a lot of these engines. First the V-12 jaguar that was a mechanics nightmare. Not noted here but the engine water pump was buried down inside the middle of the engine. When they ran right they were awesome but if something went wrong, look out. Then Cadillac 8-6-4 that was garbage. Mechanics discontinued a lot of those cylinder control systems and the owner just let it operate in 8 cylinder mode and then the engine performed pretty good. Then at the same time GM had a throttle body fuel injection what was a nightmare even if just pulling the intake manifold because of coolant leaks, ask me how I know. Then ford with all its issues had a variable venture carburetor what a nightmare. Then that Chevy Vega all aluminum 4 cylinder what piece of crap that was. Then the Oldsmobile 350 diesel and all the other 350 ci engines that where converted to diesel engines where crap. I’m forgetting a lot of engines.
You forgot to mention the 6.4 Powerstroke. I love fords and the powerstroke engines, my personal being a 7.3, but the 6.4 was bad. It was prone to all kinds of catastrophic failures. Quite a sour ending to the Ford/International Navistar collaboration.
Hey guys, YOU forgot the Dodge/Chrysler 3.7 and 4.7 !! These engines like to drop valve seats or overheat and crack the cylinder Heads. They are very hard to remove and hard to get back together!!!! JEEP means JUST EMPTY EVERY POCKET!
Ht4100 had an aluminum block and cast iron heads? Apparently GM didn't learn from the Chevrolet 2.3 liter Vega 4 cylinder. Hope they fired those engineers.
Cant have the 2.2 and 2.5 in so close in the same videos bro, after dealing with mail trucks (llvs) for several years, that 2.2 compared to a 2.5 is like comparing a Fiat to an old Toyota diesel, respectively.
I woulda put the RX8 rotary engine somewhere in there. Practically disposable engines with poor longevity. See them for sale all the time stating engine was replaced.
That's cuz most of nissans engines are fairly solid....now the 4cyls after 2010....yeah a lot of them are hit n miss. VQs are great overall with minor issues here an there. The VKs , pretty much the V8 version of the VQ are solid too... Now the VR30 is hit n miss but the VR38 is bullet proof. We will have to see how the new VR35 is. I've got a VQ38 and a lot of techs are saying that's currently the most reliable one to get these days
I have a Dodge Charger with the v6 2.7. It currently has 180,000 and it's running great. I have changed the timing chain, water pump, oil pump and cooling fan and it's running really good. I like the gas mileage I get out of it.
The GM 3.6 V6 says between 2005-2010 but it's still trash to this day. And GM fixed the Northstar V8 right before they killed it. 2005 and up are good 2 go!
I had a Pinto with the 2.8 v6 that I was UNDERWHELMED with in 78 pinto hatchback. Plugs were hard to change, The Oil Pressure with required you to lift/remove the engine out cause it was up front right on top of the left motor mount and constantly leaked. The valve covers constantly leaked and were very hard to change, too many hoses and wires to remove to get to the valve covers. It also ran thru water pumps and you had to drop the rack and pinion to change the starter. The silver paint was terrible and faded to gray in 2 years. It also liked to use oil if you ran it over 60-65 on the highway. My least favorite engine and haven't owned a Ford since!!!!! If I ever buy a Ford again, Please arrest me and put me in an insane asylum, cause, I've lost my mind. Had a Mustang II with a 2.3 4 cylinder that taught me about " Piston Slap in 76 ". I'm surprised it didn't show up on the worst engine top 20!!!!
In the first couple of minutes, this video is full of photos of engines that are not even the engine they're talking about. This is another one of those sites or channels that puts up crap like this to get viewers and make money with piss poor content.
Several of these engines get an undue bad rap. I've seen a lot of Northstars, 2,2 Chevies, and 3.6 and iron Dukes with well North of 250K. Just keep the oil changes up to date. The worst on this list are the 2.8 Ford & the 1.3 Ford. Chrysler's 2.7 was a bad joke by design.
The VW EA188 part shows that you have no clue what you are talking about. The 1.9 TDI variants are one of the most reliable engines of all time. Of course there are bad models like the 2.0 TDI, but that doesn't make it "least reliable". The focus on this video seems to be mostly on American engines, so maybe you didn't have all the same engines as Europe.
Wow what a list this is. It didn’t even include the Hyundai-Kia 2.4 theta 2 gdi engine. The worst engine they’ve made and one of the worst ever made in history.
I in light of designs that came out of Britain, from aircraft (and even some of the early vaunted RR engines - throwing hot turban blades) to archaic car engines and transmissions, I don’t think British folks should be complaining about an engineering design from anybody else. I’ll be the first to admit, US General Motors, Ford and Chrysler/Stilantis make garbage, however, Leyland and Vauxhall are much worse. And Rolls-Royce, considering what you pay for it, is just insane. Tell the other companies in the world to compete in the market, did you do this by buying Japanese.
Ford Eco Boost should be Number 1 - Timing belt running in oil is the most insane "invention" in the history of cars!
That does indeed worry me. The Ecoboost was getting all this promotion! I have a 2017 F150 with the 2.7 Ecoboost. I'm getting close to 60k. No indication of any problem....yet.
especially since oldsmobile fixed the diesel in 1985 where as the ecoboost has yet to get a timing chain kit or anything like that
The psa Engines (Citroen, Peugeot, Opel) too
What were they thinking?
Actually the belt is stronger than a chain. I know it sounds crazy. But the belt is usually stronger than steel and being wet makes it stronger . Many high rpm Indy engines turn 18.000 rpm’s and the belt has been accepted as a strong choice. I wish they could be easily changed. But engineer friends tell me that they have taken the belt far beyond what they were. The key is to keep the belt short enough that it doesn’t deflect.
The lifter noise on the Ford Cologne 2.8 Liter V6 was easy to fix. It wasn't really a problem at all.
Try to find one without cracked heads. There is an entire aftermarket on them
I made it to 18 minutes and did not want to hear that repetitious six note song.
i own a 6G72. it is a bit loud but quiets relatively quick when warm
Get rid of the goofy background "music". I couldn't take anymore after about 1/3 of the way through.
I said the same thing I know about most of the engines
I was annoyed that they used the word "however" every 9 seconds.
You’re absolutely right about almost every motor in this video. You’re dead wrong about Ford’s Cologne 2.8 & Essex 4.2. I’ve been a mechanic since Christ was a corporal and I have seen ZERO evidence to back up your claims regarding these engines.

And an old friend has over 200k on his 4.2 V6 powered F-150.
97-2000 Ford 4.2 V6 had some design flaws. 2001 saw updates to the engine.
I agree on the Ford Cologne. Many years ago I had a '79 Mustang with that engine. There was a few issues with the car, but none of them was with the engine. it ran perfectly, although being a bit thirsty.
That's being a turd Polisher saying that the 2.8 was a good engine it was garbage
The Essex which gave thermal problems was the 3,0 V6. And what is problely not known in America, the Isuzu 3,0 diesel that was used in a lot of European diesels in the 2000 till 2010.
Also confused the 5.4 triton with the 4.6 2v. The 2v had the thin thread amount issue up to 2004. Slightly improved after. The 5.4 had the ugly 2 piece spark plugs that came apart and left behind the threads to extract with a special tool.
Was waiting for the ej25. Reminded me to check my oil.
And again tomorrow!
The 5.4 triton was only rubbish with the 3v. The 2 and 4v were great motors
Cylinder deactivation is still very unreliable and those engines dont last very long compared to non cd engines.
Regarding the Ford 5.4L..... you're conflating the issues of the earlier 2-valve with the later 3-valve. The 2-valve is the motor that "ejected" spark plugs, but rather than the low number of threads, the real problem is the torque specs.

Aluminium block and iron heads? What were they thinking?? SMH.
I agree on the 2.8 when i was growing up nearly everyone was buying eay to mid 80' Rangers some had the 4cyl,1 had the 4cyl turbo, and a few had that 2.8. Mated with a 5spd that 2.8 was impressive at the time and they beat the hell outta their trucks
My previous vehicle was a 2003 Ranger. 2x4 3.0 V6. I hated to unload it, but, you know.
Got a 2017 F150 2.7 Ecoboost. So far, no problems.
You forgot the kia/hyundai Theta 2.4L
The Ford 300 inline six is the champ.
Maybe my mom just got lucky, but her 32 valve north star sedan deville was bulletproof. If I had it to do over again I would’ve bought it from her. It was the ultimate shaggin wagon.
Get rid is the awful sound track, I’m trying to listen to the narrator, no noise please.
AI narrator, also I believe...people need to put the effort into making these videos themselves and narrating them themselves...
I loved the iron duke. We had had several with n issues. I did get really good at changing headgaskets on the 2 2 though
GM should have continued production of the northstar V8 it had only a very minor design flaw
200k miles on northstar 4.6, Obviously after the bolt repair, no doubt as a small error can overshadow the durability of a great engine, if Cadillac had corrected that error in time its reliability would be impressive.
It would have gone down as one of the greatest engines ever had they not blundered the head bolts
It was the earlier Northstar V8s too. Pretty much all the major issues were fixed in the final years of it
Northstar performance head bolt kit that goes up in size and to course thread is a bulletproof fix. Kit comes with the jig drill and tap set
My 3000GT with the naturally aspirated 3.0 engine was reliable, and a fun car to drive. There were no issues! The timing belt however must be replaced every 60,000 miles, or it will break, bye bye engine!
Where's the 1.4T GM ecotec?
What's funny I had several of those cars and had really good service
No mention of the BMW V10 ?
The GM 2.2 4cyl and Pontiac Iron Duke are easy to fix and very dependable. The USPS Grumman Mail Truck uses the GM 2.2. The USPS would not chose a motor that was not reliable in brutal stop and go operation. 😂😂😂😂
The mail trucks from 1993 and before all use the Iron Duke.
I had a Chevy Beretta with the 2.2. Before a few H.P. adders it was gutless, but never had a single reliability issue. My Iron Duke Fiero got a rod knock 2 days after I purchased it. Didn't know the tell-tell signs when I bought it (young, poor, and naive). My experience, I'd agree the 'Iron Duke' wasn't great, but the 2.2s shouldn't be on this list. There's millions still sluggishly pushing S10s down the road today! Take that off this list, and add the Ford Powerstroke 6.0 and 6.4 diesels.
The Ford 3 cyl. was mentioned, but no mention of the Chevy Sprint/Geo Metro 1.0L three banger? Absolute garbage.
I just got a 2025 Chevy Trax with the 1.2L 3 cylinder with the wet timing belt, started feeling kind of worried, but I paid extra for the 100k mile warranty, I put about 4k miles on vehicles every 2 months, so whenever that goes and probably destroys the engine at least can be a little at ease knowing I might get more miles out of it than the first one through warranty
In the right hands, the 350 diesel was an outstanding engine. Fuel efficient as all hell
i know i desperately want one because i LOVE the way it sounds and how a full size car with a 5.7 v8 gets 30MPG!
While I was watching the Subaru EJ25 engine part of the vid came on and the video was immediately interrupted by...... a Subaru ad.
Gotta love youtube.
great video - back ground music hurts my head
Crazy the RENESIS wasn't mentioned.

Then the Oldsmobile 350 diesel and all the other 350 ci engines that where converted to diesel engines where crap. I’m forgetting a lot of engines.
I like how most of these engines on this list are here because of the fact of planned obsolescence
3:07 min, I like the iron duke engine.
You forgot the Vega engine
15:07
I had a car with the Ford 2.8 liter engine. Never gave me any problems.
I see many ford 2.8 cologne with 300000 400000 miles on clock😊😊
Nil Toyota's on the list.... Yay!
You forgot to mention the 6.4 Powerstroke. I love fords and the powerstroke engines, my personal being a 7.3, but the 6.4 was bad. It was prone to all kinds of catastrophic failures. Quite a sour ending to the Ford/International Navistar collaboration.
Thanks for evs!
Hey guys, YOU forgot the Dodge/Chrysler 3.7 and 4.7 !! These engines like to drop valve seats or overheat and crack the cylinder Heads. They are very hard to remove and hard to get back together!!!! JEEP means JUST EMPTY EVERY POCKET!
Ht4100 had an aluminum block and cast iron heads? Apparently GM didn't learn from the Chevrolet 2.3 liter Vega 4 cylinder. Hope they fired those engineers.
The ht4100 became the ht4900 which had a great reputation.
How can people who call themselves design engineers put out such crap? They're probably at bars claiming they just invented the wheel.
Didn’t GM have that same issue with the 2006-2008 5.3 V8 Active DOD?
Cant have the 2.2 and 2.5 in so close in the same videos bro, after dealing with mail trucks (llvs) for several years, that 2.2 compared to a 2.5 is like comparing a Fiat to an old Toyota diesel, respectively.
Why did you show a Cummins when talking about a Ford?
These are AI generated.
Also shown was a brake master cylinder when talking about the Vega engine.
I woulda put the RX8 rotary engine somewhere in there. Practically disposable engines with poor longevity. See them for sale all the time stating engine was replaced.
These are all obscure engines! Talk about popular engines!
I dont like fords but i dont agree with the 4.2 being on this list
Not a single Nissan engine in there, huh? Interesting.
That's cuz most of nissans engines are fairly solid....now the 4cyls after 2010....yeah a lot of them are hit n miss. VQs are great overall with minor issues here an there. The VKs , pretty much the V8 version of the VQ are solid too...
Now the VR30 is hit n miss but the VR38 is bullet proof. We will have to see how the new VR35 is.
I've got a VQ38 and a lot of techs are saying that's currently the most reliable one to get these days
Nsu Ro80, Ingenium, Puretech...
Other than the 1 liter EB, Fords EB engines are a great lineup.
...if you're a mechanic 😂
I have a Dodge Charger with the v6 2.7. It currently has 180,000 and it's running great. I have changed the timing chain, water pump, oil pump and cooling fan and it's running really good. I like the gas mileage I get out of it.
That's a ton of work done to an engine with only 180,000 miles though.
@@bulmarogomez2567 most people neglected them and drove short distances and the crankcase ventilation system was not good.
The Water pump on the V6 engines. Were horrible. Causing over heating and blown heads. Same like the V4 van engines. 1974.
Never beat a small block chevy
The GM 3.6 V6 says between 2005-2010 but it's still trash to this day. And GM fixed the Northstar V8 right before they killed it. 2005 and up are good 2 go!
They all have the same weaknesses. Almost like they were designed to be unreliable and boost auto sales.
I had a Pinto with the 2.8 v6 that I was UNDERWHELMED with in 78 pinto hatchback.

Welp now that u detect the problem, make, sell improved after market parts to make said unreliable inventions reliable again
So were most of these turkeys a direct consequence of government smog and fuel-mileage dictates?
GM 283 cu inch v8. Couldn't kill it. 1966 parisienne. 😊
VW 1.7 litre inl 4. Constant distributor failure. Junk. 3 distributors in 2 yrs on Dodge Omni.
Great example of why electric propulsion IS the future of transportation….
Where's the PSA / Mini engine? Now they are 💩 on a different level...
How many times can you hear the word “however” being said in this video??
Just about every fact for the 350 oldsmobile diesel section is wrong
In the first couple of minutes, this video is full of photos of engines that are not even the engine they're talking about. This is another one of those sites or channels that puts up crap like this to get viewers and make money with piss poor content.
Ford 2.5 liter is the greatest engine ever.
Several of these engines get an undue bad rap. I've seen a lot of Northstars, 2,2 Chevies, and 3.6 and iron Dukes with well North of 250K. Just keep the oil changes up to date. The worst on this list are the 2.8 Ford & the 1.3 Ford. Chrysler's 2.7 was a bad joke by design.
Strange, not a single Italian or French engine in this list...
Italian engine ?!! 😂 they are very reliable by the way. Most of The french yes, they are bad
I disagree with the order
gm 1.4 turbo
The 3.6 gm v6 shows Cadillacs 3.6tt 😂 there are not the same timing is revised and heads are different
Although the block is the same? One wonders if the turbos bolt on
The VW EA188 part shows that you have no clue what you are talking about. The 1.9 TDI variants are one of the most reliable engines of all time. Of course there are bad models like the 2.0 TDI, but that doesn't make it "least reliable". The focus on this video seems to be mostly on American engines, so maybe you didn't have all the same engines as Europe.
Wow what a list this is. It didn’t even include the Hyundai-Kia 2.4 theta 2 gdi engine. The worst engine they’ve made and one of the worst ever made in history.
Rich piana
Kamala is chiming in.
This is why I only buy Honda
It seems these car companies have learned lessons of their past.their still producing junk.
It seems American motors are overrepresented among badly designed motors. - And Americans wonder why American cars don't sell in Europe 😂.
