You pretty much nailed it. I’m an auto tech by trade,and I’ve experienced all the problems you’ve talked about here,junk every one of them,except for the ford 1.0 pos.a wet belt?really?whoever designed that was an assclown.

*LOSE THE ROBO-NOUNCER!!*

Many, many of your pictures are totally out of sync with the story line. Example: you're slamming the Olds 5.7 diesel, yet showing images of a 1972 Old Cutlass predated the diesel engine by what, 10 years? You talk about the 3.7 Chrysler engines issue but show mostly vehicles that did not use this engine, and even one image of an early 1960 426 Hemi engine which doesn't ever use the same paint as the 3.7. You seriously need to match the images to your AI narrative.

Q: Why do the British drink warm beer ? A: They have Lucas refrigerators.

All the “sludge” engines are poor maintenance. Believing the recommended interval by the manufacturer is the down fall. 3-4000 max or 1 year no matter the mileage in that year…

What is a "leemon" law😂😂😂

You guys did a lousy job what the hell is a Leamon law?

Discussing Cadillac engines but showing ol Henry Ford and his flathead! 😂

What's a Leman law. Hire a real person to read the scripts.

The V864 engine was actually a good engine. Downsized 425, the electronics were the problem, mainly in the six cylinder mode. Disconnect the electronics, if I remember, cutting a blue wire at the trans would disable the system.

Lucas- The Prince of Darkness

Twp others I would note: 1970's GM/Chevy Vega I-4. 1st Generation and other Mazda rotary engines.

Lucas, the Lord of Darkness. Why do the English drink their beer warm? Lucas makes refrigerators too.

I definitely don't know as much as AI, but the exhaust tone is going loud on a Cutlass drag car

On the 2-valve version of the Ford 5.4, it's been claimed frequently that torquing the spark plugs to 25 ft lbs seriously decreases the chance of a plug blowing out.

Gotta add the 1971-1975 Chevrolet Vega 2300 aluminum block 4-cylinder: a) Silicon coating on cylinder walls in place of liners. b) Open-deck engine block design. c) Insufficient coolant passages. Many of the engines would overheat, causing the coated cylinder walls to be scored. The engines had an improved head design, water pump, and revised coolant passages by 1976. It was used in GM's "H" Body vehicles, including the Chevrolet Vega, Chevrolet Monza, Pontiac Astre, and Oldsmobile Starfire.

Lucas wiring harness on the Jag, reminds me of the old riddle: Q: Why do the British drink their beer warm? A: Because Lucas makes wiring for refrigerators too!

The Chevrolet Vega is happy it was bumped from this list! 😂

The reason the British have warm beer... Lucas refrigerators. ;-D

6:19 "Leemon Laws" ... pretty sure its called lemon laws ... AI voice-overs suck

The Triumph TR-8 used the Rover 3.5 V-8. Though it was rated at something like 125 hp with a couple upgrades and aftermarket exhausts it sounded good and had that torquey pull we all love

Dont forget about the 6.0-fixo and the 6.4 powerstroke.

Mopar tech here. The 2.7 was flaming garbage. Sludge buckets even when properly maintained. The water pump was the killer.

GM’s 2.8 V6 was a terrible engine also. A complete slug and horribly underpowered.

Belt driven oil pump? Nice! 😂

Ford 5.4: Sludge buildup is caused by lack of maintenance. The real problem was in the radiator. Part of it is the transmission fluid cooler and a compromise between that and the engine portion allows transmission fluid mixing with engine coolant. This eventually destroys the engine and transmission. Other brands using the same radiator supplier had the same issue.

Agree on the Triumph engine water pump. But like many engineering disasters, people work out how to fix them. Mine has a Ford V6 water pump mounted where the alternator sits, nice and low, the original pump removed and blanked off and an expansion tank up high where they should be, and the alternator repositioned where an AC compressor would fit for US markets. Simple changes that could have saved the engine in early design, but involved politics.

AI voiceover and irrelevant pictures make this a sucky video.

Why do the British drink their beer at room temperature? Because Lucas built the refrigerators!

I did some work for Lucas in my days in the UK. The people I worked with told me why it's called Lucas the Prince of darkness. They said do you know why English people drink warm beer? Answer: they have Lucas refrigerators!

The two valve 5.4 Triton is a nearly bulletproof engine that goes as much as 450,000-500,000 miles with few problems.

Among riders of British motorcycles, and drivers of British cars, George Lucas is known as "the man who invented darkness," and they tell the old joke, "Lucas headlights have three settings, off, dim, and flicker." The systems were not too bad early on in the 1960s up until 1972, but as they got more complicated they got worse and worse.

1971 Chevrolet Vega aluminum block ohc 4 was probably the worst disaster of them all...

Most of the issues with the Ford 5.4 Triton 3v can be avoided completely by just changing the oil on time and letting the Ford service department handle changing the plugs (they break it, they buy it). Mine has 300k miles and counting with just routine maintenance.

That Eaton V8-6-4 package that almost ruined Cadillac was originally developed for Ford, and was getting close to production. But Ford pulled out late in the development program because of operational problems that eventually bit Cadillac. I was with Ford Engine Engineering at the time. Eaton had invested a lot of money (theirs and Ford’s) & resources in the program and asked Ford if they could offer the system to other OEMs. Ford said, “Knock yourself out. We aren’t going to put it into production.” The rest is history.

If you’re such a mechanical god,then tell us what motor they are introducing that’s trash? All this hindsight crap is useless.

The caddy t4100 is the biggest pile of dung...

Let's see, we show Henry Ford and his Flathead V-8 when discussing Cadillac, then lee-mon laws and top it off with Ford F-One-hundred-fifty pick up trucks. What a crappy video. I can't believe I sat through the whole thing. You really should have somebody that knows just a little bit about cars review things before you hit the "Submit" button.

first gen 5.4 two valves were good engines. it is true though that after the first spark plug change they could spit out spark plugs . there is a very lengthy procedure no one ever follows to get the spark plugs out without damaging the threads in the head so some of the threads are missing when the new plug goes in .

That’s no surprise at all. These horrible bad engines were made after the 70s. And actually the Ford triton 5.4 with a good motor until they went to three and four valves per cylinder clearly were over engineered and became less reliable immediately.

1982 Oldsmobile Diesel ⛽️

How in Gods' name could you omit the HT4100 Cad engine????//

"LEE-MON" laws ? This narrator's native tongue is English...American English ?

A Belt dipped in oil.. 🤣😂

You have the Cadillac 8-6-4 operation wrong. The solenoids prevented the valves from opening....so the piston would compress the air trapped in the cylinder and then it would push the piston back down like an air spring losing little energy and keeping the cylinder hot. Most of the issues with them was due more to very poor machining than the electronics. I worked on several and had to pull the heads because they were just horrible and couldn't seal the head gaskets. GM's solution was to fill them with 'stop-leak' which just clogged everything up while the dealers all blamed the fuel injection and electronics running the cylinder deactivation. Once we got the engines machined properly they ran really well and it was neat to see a full size Caddy breaking 20 mpg's on the highway.

Nice job saying Olds Diesels are loud and then playing an audio clip from a Cutlass with what is clearly a GAS engine. I guess you’ve never been around anything built before, so loud must mean Diesel in your world. Also, learn how to use text to speech software! Listen to the project once finished and go back and modify the spelling to get it to say words correctly. For example, the video says what sounds like “leeman law”. If you spelled it correctly and it still did it, alter the spelling and test. It doesn’t matter how it looks in the text as we don’t see that. I have to do it all the time in my company’s phone system. You should see how bad I have to spell foreign names to get them to sound correct when it says them!

VW \ Audi 1.4 TSI, especially the methane ( CNG ) powered Ecofuel version, is probably Vws worst engine ever, very fragile and prone to early engine failure. This engine together with the equally bad 7 speed DSG dry clutch transmission had so many failures that taxi companys in Sweden were not allowed to buy them anymore. Opel 2.5 V6 is another timebomb, personally know 2 people who had engine failures with this engine. Audi 3.2 liter 90 degree V6 used in the Audi A4 and A6 in the mid 2000s, was the engine that topped the list of engine failures in Sweden during that era. It was a totally different engine than the solid 3.2 liter narrow angle VR6 used in the VW Golf R32 and Audi TT 3.2. Jaguar 4.0 liter v8, Jaguars first v8 launched for the 98 model year was also very fragile and suffered engine failures because weak camchain tensioners, and often loss of compression due to it's Nicasil cylinder liners wearing away, many buyers guides tells people to stay away from these early v8 Jag fails. Volvo B19 and B200 engines in the very unreliable Dutch made Volvo 360:s, these engines were very stubborn and tricky to start, and despite being upgraded to fuel injection, the problems persisted, they were still a gamble to start. And don't forget Volvos other lemon : The PRV ( Peugeot, Renault, Volvo )V6 engine that was super famous for overheating and failing due to it's very poorly designed cooling and oil system, which restricted flow and caused alot of problems. Bmw 1.8 liter 4 cylinder engine used from the early to late 90:s 318 E36 and 518 E34 were so good at eating cambelts that the interval had to be shortened to 40 000 kms.

Triump v8 suffered quickly from any poor maintenance . Triump v8 was not siuted to hot weather . Larger alloy radiators were very very common fix .

We always called Lucas electrical the Prince of Darkness, Lucas is the reason the English drink warm beer.

Lucas.....The Prince of Darkness...

5.4 triton: am i a joke to you?

Wow lots of miss information

I never buy an engine with a timing belt or a water pump mounted inside the engine!

I do not like these videos. The photos do not match the story. You start talking about a Cadillac engine and show a photo of Henry Ford with a Ford engine. Olds diesel and a photo of a Ford car. This is just slapped together crap.

Don't ever buy a British bike with Lucus ignition! Bad from the start especially in the 60s with their positive grounds!

GM also offered the Olds diesel in other brands of cars and pickups.

VAG engines from 2006 and forward. Plastic melts in coolant system, plastics crack in oil system, fill with oil and check gas, stretched cam chains, oil leaks, oil sludge in intake manifolds, water pump fail, bad cam drive, I just hate them. Don’t you just love when the engineers remove the oil check stick? So you have to go into the info system and look there!? That’s one of the dumbest features I’ve seen.

Joseph Lucas a.k.a. the Prince of Darkness

There's Audi and Hyundai 4 bangers.

Yeah....I'll be getting rid of my 2004 3.8 Buick Lesaber and my 3.8 1999 Buick Park Ave real soon..... NOT!!!!! The latter has 416,000kms and it still runs like new and both deliver fuel mileage in the low 30s. Gotta love all the new tech. Straight up sucker play. Only a idiot with deep pockets buys a new car.

If this was for new cars the list would be nearly endless.

I would offer the Audi range of V6's & V8's and Jaguar Land Rover V6's and Igneuim engines as expensively good engines, ...that are designed to fail quickly when nearing their next service intervals, and often require engine out to a cess anything more serious than the oil filter. This helps their dealerships stay funded via costly repair times to fix simple things, but that's assuming the owner/user regularly looks after oilchanges and has some mechanical sympathy to notice minor issues before they degrade! and that they allow the engines to warm up correctly before spirited usage.

the worst thing about that Jag v12 isnt the reliability. Its the fact that with twice as man cyl as the I6, it only made an extra 40-45hp.... At the cost of all that weight over the front, poor economy, and difficult to work on

My Grandfather had good luck with his.oldsmobile. Drove it cross country twice. He owned the oldest CASE tractor dealership in the US. Other family members had nothing but problems.

The Ford 5.4 V8 is OHC not OHV

"Leemon Law" 🤣

It was only the chrysler 2.7. My son is driving my old 3.2 with 245,000 miles and is showing no signs of giving up

Ford F250 diesels post the 7.3 litre International engines. I.e. 6.0, 6.4 litres.

While i have had experience on many of the engine failures that you mentioned in your video, one always really stuck out to me and tops my list as the worst engine ever produced. The Ford 6.0 Powerstroke diesel. Failed head bolts causing head gasket failure, high pressure oil system failures, early injector failure, FICM failures, ECM failure, VGT turbo failures, up pipe failures, EGR cooler failures, oil cooler failures, failures with the fuel system that allows water to get into the injectors, expensive oil leaks, engine repairs are often done by removing the cab of the truck. I have never seen an engine with so many problems and failures in my career. Also, the cost to make these repairs can be staggering.

Talk about Chevy V8 with a picture of Henry Ford in front of a Ford flathead V8! Good job.

3:16: "Cadillac pioneered V8 engines as early as 1914". Yet, you show a picture of Henry FORD, with his FORD flathead V8....Wow, you guys are about as sharp as a spoon!!!

The Stag (a beautiful designed car), should have went with the 215 c.i. American sorced Buick V8, like Rover did. They could have been licenced to build their own and sourced GM's overflow very, very cheaply, probably.

I have a Holden with the 3.6 V6 and I'm very pleased with it, although mine is an ex-cop vehicle and has been chipped. High mileage now - 309,000km - but due to the excellent maintenance by the police mechanics I've had no real problems. Barring major accidents, I plan on keeping this car as long as I can keep my licence. (I'm 74 now).

My EcoSport came with the 2.0 four cylinder. Good small little car I avoided the 1.0 great video do one on transmissions

Some good information here - videos should show the actual engines as they're being discussed.

Any vehicle made during the malaise era gave auto manufacturers bad names… may Toyota, Honda, and Nissan were the exceptions.

You forgot the GM 1.4 and 1.5 ecotec turbos they chew through turbos and pistons, Navistar maxxforce 11 and 13 engines which plagued many International Semi tractors, the 6.0 powerstroke, and 6.4 powerstroke.

Ford Eco Boost as used in the Focus here in the UK. Regretfully, we bought one of these on the back of claims it was far more powerful and torquey than it really was, and nor did it achieve any sort of fuel economy. I knew it was a mistake the day I drove the car home and sold the pile of junk literally weeks later. Not been back to Ford ever since!

Perhaps they were too long ago to be remembered, but the Chevrolet Vega aluminum block 4 cylinder engine was pretty bad. They did not sleeve the cylinders with steel sleeves, but instead counted on a silicon impregnation of the aluminum inside the cylinders to make them resist the wear from the pistons and rings. Trouble was that if the engines ever overheated, and sometimes even in regular use, the silicon would migrate out of the cylinder walls leaving them soft enough so that the piston rings soon scored them and the engine was ruined.

My cousin had an 81 Cadillac with the V8-6-4 disabled, and it was a great car.

Crapillac Gone North Star was absolute Garbage a was the Dogg 2.7 Vjunk

One thing you forgot to memel about the 2.7 Chrysler is that the water pump was actually internally mounted. I mean how could that go wrong? Water pumps never fail and leak do they??😅 Gold star to the engineer who dreamed up that boondogal

The North Star has the starter in the intake valley. Whom ever designed that needs a kick to the croatch! And the Sebring is total shit! My mom had one and it spent more time in the shop than driving.

You forgot the worst engine of all-time model t engine. No oil pump, water pump, fuel pump, and no dip stick. These didn't last 30,000 miles if that. They had babit poured bearings which couldn't be rebuilt. Parts were cheap and plentiful that was the good thing about engines.

2:04 Triumph had been designing their V8 for YEARS by the time Rover/British Layland bought the "Rover 3500" from GM. Car was too far into the design cycle to change it. They DID use the 3500 later, in the TR8.

Triumph's management didn't just 'choose' to not fit the aluminium V8 Buick engine that BMC by then was using in the Range Rover & other vehicles! The real problem was that under the licencing-agreement BMC/Leyland wasn't permitted to fit the Buick V8 into any vehicles that were to be sold in the USA (or anywhere in the Americas), but they really needed to export cars for all those American-sales to stay afloat financially!

Why not look at Ford and other companies "Wet Belts", disaster, and Mercedes and Audi , and VW putting the timing chains the BACK of the engine ,Peugeot have wet belts too , which soon by pass the oil filter and clog up the oil strainer causing oil starvation and ruining the engine 😒😒

first 45 seconds can be applied to anything, from cars to kitchen appliances. I got drawers full of bad promises

The 4.6 Northstar had nothing in common with 4.4 Northstar (LC3) other than name. The LC3 was only in the V series STS-V and XLR-V. Very low production but no real issues and much more reliable than the 4.6.

Most people have never heard of Triumph!

The Chrysler 2.7 liter and the 3.2 liter are not the same engine. The 3.2 is a smaller 3.5 liter belt driven SOHC V6, the 2.7 was a chain driven DOHC V6 and only came in 2.7 liter displacement.

No mention of the Cosworth slant?

Another motor for the list Nissan A series engines (A12 to A15) used in the f10, b210, 210, and sentra thru 89. Bearing defect on the crankshaft caused em to fail from 50,000 to 85,000 miles.

A good number of these bad GM and other engine designs are what happens when car makers are strong armed by the government to design and build something overnight to suit unrealistically rigid "get it built now" mileage and emissions standards. The older Cadillac 472" and 500" (really a 502") were excellent, designed by Cadillac with no outside interference, their only shortcoming was low mpg - also the Oldsmobile GAS V8's were also some of the best ever designed, them and the Cadillacs were very smooth and reliable. Many GM govt. forced engines after this er were hastily/badly designed and built out of forced necessity and many GM engines that came after this era were horrobly unreliable and low powered.

Got to love those Leeemon laws.

Of course, the first engine discussed has to be the Stag V8.

Probably should do a bit more research so as to get the details correct and clear out the engines that had problems due to engine management systems rather than mechanical issues. Plus, the Northstar had problems because the threads for the head bolts pulled out of the block as do a few other manufacturer's engines. We would probably see less of that if the engines weren't consistently ran at temperatures above 220 F.

GM 307 CI engines were all bad as far as I can tell. It wasn't actually a motor problem, but the camshaft lobes would round off. I don't know anyone that had one and didn't have cam problems.

"Leemen" laws? lol

I think Jeep's 3.1liter td engine should be mentioned here
