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.
Even the dry belts from older DOHC and SOHC engines are much better
i find the wet belt thing funny.
You immediately see who knows his stuff and does it right and who not.
Almost every brand uses wet belts. Every brand has the same problems when maintained wrong.
Volkswagen TDI Engines have wet belts, Honda use wet belts, the complete stellantis company uses wet belts.
All of them clogg the oilpump and snap when using the wrong oil or ignoring cycles.
And all of them do 250.000 Km+ when you actually care about your car.
You just can not be that farmer technician saying "yea, we take the good ol 40W 60". Yea, you actively destroy the engine.
"Oilchange every 20k Km? Nooo, that is bs, every 50k is enough".
Yea, this just filters out the people knowing their shit and those who dont. Pretty descend in my oppinion. Makes many things easier.

*LOSE THE ROBO-NOUNCER!!*
I hear you, dude. I guess they can't find a human that can read aloud.😢
It's all AI nonsense
Does the guy that used to narrate ''The World's Wildest Police Videos'' ... (John Bunnell) know his voice was stolen by AI?
He sounds like chuck schumah.
@jerrynorton1080 at least the AI program did not lie every 30 seconds throughout the entire video....
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.
these videos are often just made with AI tools - I notice the narrator said 'leemon' instead of 'lemon', so it's an AI voice also.
You offering to help?
I see that kind of mistake with these Internet nerds all the time. They only know about Datsuns and Toyotas.
Also, talking about Cadillac pioneering the V8 engine while showing Henry Ford posing with his flathead V8 of 1832. Stupidity
.
Sorry, that should be 1932. My bad
Q: Why do the British drink warm beer ?
A: They have Lucas refrigerators.
We used to refer to Joe Lucas as "The Prince of Darkness." You could get stuck in the middle of nowhere when your electrics suddenly quit.
I've never known anyone over here, in the past 40 years at least, to have a Lucas Fridge
That's an old myth which you should give up on. Same as the teeth one.
The Chevrolet Vega is happy it was bumped from this list! 😂
Discussing Cadillac engines but showing ol Henry Ford and his flathead! 😂
Isn't that just like a dunce?
What is a "leemon" law😂😂😂
Shitty AI narration!
Is this an AI voice?
I caught that too. Makes me laugh.
You guys did a lousy job what the hell is a Leamon law?
If you listened it's a Lemur law, this came from defective Lemur's imported from Madagascar as pets.
Obviously a law named after Lee Munn, the University of Mary Hardin-Baylor football player.
Al voice
Twp others I would note: 1970's GM/Chevy Vega I-4. 1st Generation and other Mazda rotary engines.
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.
I think in the end, it was a decent V8 without all the electronical gremlins and issues, so yeah...cutting off the 864 system would turn this engine into a much more livable engine
Mopar tech here. The 2.7 was flaming garbage. Sludge buckets even when properly maintained. The water pump was the killer.
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.
Click and Clack also claimed the Vega body was made of compressed rust. I owned a '73 Vega in the N. Indiana rust belt. The outer door panels and quarters were completely loose at the bottom of both sides in 3.5 years. Also, went through one warranty engine replacement, dumped it when it needed the next [out of warranty].
Lucas- The Prince of Darkness
My wife (also a motorhead) walked in just as Lucas was being mentioned - and reflexively intoned "Hail Lucas, Prince of Darkness"! LOL
Yes, one reason for the downfall of the British motorcycle industry.
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!
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…
Correct...but there are sooo many engines you can actually abuse to 300k Miles...those you can abuse to 75k even..but they last if taken care of..just not as good
1971 Chevrolet Vega aluminum block ohc 4 was probably the worst disaster of them all...
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.
I have a 98 Econoline 2 valve , I blew one plug and had them all replaced . It has 261,000 on it , runs good.
Yep! I've been driving nothing but Triton engines (4.6, 5.4 and 6.8) for the last 25 years (All 2V- the 3V's suck) and buy high-mile vehicles and keep 'em till at least 300K miles and have NEVER had a problem- Only sell 'em 'cause of rust and paint/clear-coat problems on the bodies. Use only Motorcraft plugs and torque like any other plug. It seems that Ford initially set the torque way too low. (Now I have two 6.8 V-10 2Vs- and they are my favorite engines I have ever owned)
Still think the 2 valve engine is a good one and would recommend it to anyone. Personally, i feel that the plug failure is due to not using a torque wrench to tighten the plugs in combination to 4 thread plugs in an aluminum head. Once you install the steel inserts in the heads for the plugs, it is a rock solid reliable engine. THe 3 valve, on the other hand, is hot garbage to be avoided.
@@fixxerautomotive4917 The problem with spitting the plugs was that Ford initially specified a torque value that was way too low...and torqued the plugs that way from the factory. If the original plugs didn't pop, replacements likely would if the installer used the Ford torque specs. Another problem was using other than Motorcraft plugs. Never use anything but Motorcraft with Triton engines. I've been driving nothing but 2V Tritons for last 25 years, and have never had a problem...typically sell a vehicle when it has over 300K miles on it, and they still are running like a Swiss watch. Currently have two 6.8L V-10's (Just a 5.4 with two more cylinders) each just turned 200K...- Love 'em!
@@bobbylibertini Yeah, the 2V is my first pick in Ford motors- 300 modified/400. is my second favorite. Ive seen many push over 300K. Typically they outlast the transmission and the body.
What's a Leman law. Hire a real person to read the scripts.
Nothing taste better than an ice cold glass of leemen aide on a hot summer day?
Lucas, the Lord of Darkness. Why do the English drink their beer warm? Lucas makes refrigerators too.
12v positive ground, British standard Whitworth bolts, lever shocks, the cost of replacing them was more than I paid for the car. Plywood floor, and on and on, the joys of a MGA. And then was almost stupid enough to buy a Jaguar XKE 2+2.
The Jag V12 certainly wasn't the worst engine design here, but it did rely on one of the worst component manufacturers in Lucas.
Whereas your Ford 1l eco boost car is only the tip of the iceberg. Any three cylinder ecoboost 1 l engine fitted to any Ford model especially in Europe, all have wet belt engine systems that are prone to failure by design 😫😭
Haha very funny lol
I believe the beer in England is made to drink warm.
Cellar temperature, not warm.
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!
I definitely don't know as much as AI, but the exhaust tone is going loud on a Cutlass drag car
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.
Better off fitting the Range Rover v8 a much better engine
@@bmwman1981 Modern RR engine yes, but back in the day issues with those as well. Many that did swap out the Triumph V8 are changing back as they're worth more original.
@@royster3345 still rather have the old 3.9 over the triumph engine
I wonder if just drilling and tapping the housing up top for an air bleeder would do
Triumph had the chance to use the Rover V8 but turned it down. Huge mistake. A common repower here is to put the Rover V8 in the Stag, apparently works just fine.
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.
6:19 "Leemon Laws" ... pretty sure its called lemon laws ... AI voice-overs suck
14:44 "Ford F-One hundred and fifty" 😀
Dont forget about the 6.0-fixo and the 6.4 powerstroke.
There it is I was wondering if my 6.4 made the comments lol
6.0 Powersmoke is the worst engine ever IMO.
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 .
GM’s 2.8 V6 was a terrible engine also. A complete slug and horribly underpowered.
That is not what he means. He is talking about reliability issues, not performance.
3.4 GM was the issue, the 2.8 and 3.1 were great engines…
@@NewEdgeDesigns had a grand an with the 3.4. 168k miles when I traded it in and still ran ok. Needed a lot of other things fixed but 3.4 was solid.
The reason the British have warm beer... Lucas refrigerators. ;-D
Lucas also makes vacuum cleaners. They all suck!
British do not drink warm beer. Just like all Americans are not fat.
The caddy t4100 is the biggest pile of dung...
How in Gods' name could you omit the HT4100 Cad engine????//
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.
Belt driven oil pump? Nice! 😂
Ford is still making engines with the belt drive oil pump in Europe and it is causing some serious problems there.
@@leonb2637 Belt drive systems are overall pretty reliable, if the belt is at least visually accessible. I've never understood why they enclose timing belts. They're usually dry so why not put them out where they can be inspected.
Belt driving an oil pump is absurd. 🙄
Pontiac had a rubber belt driven oil pump in the ohc6 not a problem
The most ridiculous thing I have ever seen.
But it was dry, not wet. Also, Pontiac tested it for 100,000 miles on dirt roads with no timing cover. Only when they proved that it could stand up under that harsh condition were they given to go-ahead for production.
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.
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.
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.
4100 was worse.
Never knew that!
Why do the British drink their beer at room temperature?
Because Lucas built the refrigerators!
1982 Oldsmobile Diesel ⛽️
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 .
"LEE-MON" laws ? This narrator's native tongue is English...American English ?
A Belt dipped in oil..
🤣😂
GM also offered the Olds diesel in other brands of cars and pickups.
We always called Lucas electrical the Prince of Darkness, Lucas is the reason the English drink warm beer.
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
The engine they are talking about is not the Rover/GM V8. The one in the vid is the TRIUMPH V8 which was a disaster. I worked on both engines.
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.
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.
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).
5.4 triton: am i a joke to you?
Wow lots of miss information
Cadillac HT4100 engine was also notorious for failure.
Ford F250 diesels post the 7.3 litre International engines. I.e. 6.0, 6.4 litres.
The two valve 5.4 Triton is a nearly bulletproof engine that goes as much as 450,000-500,000 miles with few problems.
Sure it is champion.
Are you living on another planet???
Lucas.....The Prince of Darkness...
My EcoSport came with the 2.0 four cylinder. Good small little car I avoided the 1.0 great video do one on transmissions
Don't ever buy a British bike with Lucus ignition! Bad from the start especially in the 60s with their positive grounds!
Talk about Chevy V8 with a picture of Henry Ford in front of a Ford flathead V8! Good job.
Glad I am not the only one who noticed.
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.
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!!!
I never understood that diesel engines in cars. Why do you need more torque in a car you’re not pulling anything of significant weight makes no sense.
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 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!
If you’re such a mechanical god,then tell us what motor they are introducing that’s trash? All this hindsight crap is useless.
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.
If this was for new cars the list would be nearly endless.
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.
3:06 The Cadillac or General Motors V8/6/4 engine was such a flop. The thing that blows my mind is the fact that GM is still doing it to this day with very unreliable results. It’s called DOD or displacement on demand. Basically, it’s cylinder deactivation, and it is so unreliable that most owners just have it deleted. Otherwise it will definitely ultimately destroy your engine.
AI voiceover and irrelevant pictures make this a sucky video.
"Leemon Law" 🤣
I never buy an engine with a timing belt or a water pump mounted inside the engine!
Same here. We obsoleted internal timing chain driven water pumps in the early 30s, but the Japanese brought them back. I don't know why people accepted that outdated concept.
@@jamesbosworth4191 Most people have no idea about these issues. Most women buy a car because they like the color!
@@stephenvelden295 I know, they are clueless. That's why there are now cars with no transmission dipstick, and, I here now with no engine oil dipstick either.
@@jamesbosworth4191 That's N.S! My wife's '17 KIA Forte we bought new has no trans dipstick. Otherwise a hellofa good car.
@@schizy I refuse to buy a car like that. The later Chrysler and Ford products don't have one, but they DO have a dipstick tube, so you can put one in, but cars with no dipstick tube? Count me out.
Some good information here - videos should show the actual engines as they're being discussed.
Joseph Lucas a.k.a. the Prince of Darkness
I’m glad I’m retired from the automotive repair business !
Me too! I was an automotive tech for 55 years. Owned my own garage for the last 40 years and 8 months. By the end of my career I no longer felt like I was repairing anything, just replacing and programming modules.
@@reallysanta7653 I miss the days diagnosing with the giant sun performer tester. Doing real tune ups, plugs, points&condensor, valve adjustment, carburetor overhauls etc. Back in the day when cars had real maintenance and made more money.
I drive a 2003 honda hatch si, with a 2.2 liter, 215hp four cylinder 😂😂😂. A great engine.
I also have a 1965 galaxie 500, w/ 428….also a nice engine.
And a 1966 merc comet w 351 mc….almost a bulletproof engine.
My advice is to find a ride that has an engine that’s been in production for a long time w/ a proven track record.
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!
Alloy diesels have higher engine noise that their cast iron cousins, it has always been a problem with lightweight diesels.
Thank God that nowadays we can avoid that garbage engines and engines all together by simply make a smart choice and buy a simple EV!
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.
Those were superb engines. They were lifetime engines. After they wore the car out, they could be modified into marine engines.
Totally agree, take Al Gore out of the equation, and most of these failures would never have happened.
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!
Interesting, Rover sold the SD1 fitted with that engine in the USA from 1980. Was there a change to the licencing agreement, i did not think it changed but I could be wrong.
There have been a number of reasons suggested as to why the Rover engine was not used. One of the more favoured ones is that Rover did not have the capacity to supply Triumph's requirements as well as their own.
I owned a P5B Coupe and i can tell you that the early Rover V8s were not without their issues, the lifters, cams and rocker gear was not up to snuff and wore quickly, the lifters and rocker gear were standard GM and easily ugraded. The rings broke as well, damaging the pistons The majority of he engine was okay, the casings were better and more substantial than the original Buick ones but Rover had not bedded down the engine at that stage.
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
You forgot the GM 3.4 DOHC
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.
The Ford 5.4 V8 is OHC not OHV
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.
That was one of the all-time worse engines ever, unless you sleeved it and used 4 ring pistons.
Some of the earlier examples of this piece of junk would last up to 20k miles before imploding.
@@reallysanta7653 That's why I am puzzled about people who don't like the Pontiac "Iron Duke" 4 cylinder. That engine was SUPERB compared to that Vega disaster.
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.
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.
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.
Never liked aluminum engine for street use.
Also the earlier "HT 4100" engine with weak aluminum threads holding such as main bearing caps and cylinder head bolts.
@@davidpowell3347 Have never been in favor of using aluminum for regular passenger car engines. Too fragile.
There's Audi and Hyundai 4 bangers.
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.
first 45 seconds can be applied to anything, from cars to kitchen appliances. I got drawers full of bad promises
Fair enough.. Haha
@@ItsJustCars. How well does the fuel economy of the Ford ecoSport with the 3 cylinder engine compare to the Geo Metro with the 3 cylinder engine ?
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.
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 😒😒
At 5:18 I think that is a picture of the Oldsmobile V8 that was introduced in 1949 and in a bored and/or stroked version was the engine used in my grandfather's 1956 Oldsmobile
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.
I don't remember the "Leeman Law" ...😆
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.
they showed henry ford standing beside a ford flathead v8 when talking about a cadillac engine and used a gas engined oldsmobile as the example sound for the olds diesel...
Any vehicle made during the malaise era gave auto manufacturers bad names… may Toyota, Honda, and Nissan were the exceptions.
A stretched timing chain resulting in metal particles in the oil 7:50, now that is quite a stretch
Most people have never heard of Triumph!
Of course, the first engine discussed has to be the Stag V8.
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
I agree with your assessment although the aluminum blocked V12 was almost the same weight as the venerable cast straight 6! The core of the Jag V12 is actually a very good engine - I was involved in a project where we supercharged one and got over 900hp without any changes to engine internals except pistons. We could have got more out of it but the rest of the drivetrain limited what we could do. It never had any cooling issues and it was dead smooth. The Lucas Optronic system was definitely the achilles issue. All V12s are a rich man's game.
