damn that boxer diesel sounds hella sweet tho
I don't know what it is but they just sound so cool
@@greasysteve5671 that is because of unequally long exhaust stacks where you get two pulses in shorter succession that normally
Yeah its my video, now i have made a new exhaust you can see on my channel, its alot better sounding
@@felixbeutin9530 e eeeuuuuh no. It's due to it's flat four...
@@kimdon3430 watch engineering explained's video this and just learn for a change
even diesel from subaru has that awesome sound
Lijevi Desni there are a lot better sounding ( if you look on my channel i got a new video and took the old one down)
i own a 2010 version of that 2.0d and it doe snot sound like this and its straight piped till the particular filter. it has no rumble still, i have to delete the particular filter which is illegal... so ya
@@alexttdot4890 well then you must have did something wrong because I have a 98 2.2 liter and then some custom exhaust that's my car has that rumble. Boxer engine diesel should send more even so because it's a higher compression engine.
Cringe
Have they continued this diesel engine? I really want one
I kinda disagree with the 1MZ. It's an amazing engine, but it is also extremely popular with American blonde women who don't like to change oil so I just think of it as the engine is fighting back.
Blake Parker Does the turbocharged 7mge in USA suffer from the same issue that is mention in this video or is it better to get an N/A 7mge?
Arz2003 like he said in the video, toyota made a big No No by putting a turbo on the 7m.
The 7mge wasn't any different.. Got 440k kms from a Cressida..done the head gasket once at around 210k kms.. Pretty tough Engine was surprised to see the 7mgte on this list
Blake Parker I agree the 1mz is an amazing motor, any engine will suck if not maintained
they are prone to get oil sluge. just service the car and itll be fine. defiantly not a list i would put this engine in, maybe a top 5 best engines
Rewatching 2 years later - Gotta say, I love how our friend VisioRacer included clips of each engine performing well in non-broken state and sounding good doing it. Goes with his initial disclaimer that just because they're on a "bottom-5" list doesn't mean they're bad engines, just that they have significant problems to look out for.
A boxer diesel though that’s sick as fuck though hahah. Sounds really good too
I've heard mostly good things about the boxer diesel. *Shrugs*
Bboy 1hunnid Excactly, especially on rally if you seen a Forester diesel rally car
I had a legacy Diesel chipped with from 160.000 km bis 300.000 km without any Problems only sold it because sombody drove in my car!
My Forester is used in this video , its not one of the first engine models its a 2011 engine (the better euro5 engine) , never got any problems and i hear alot of good about this engine
dpf is a common issue for many diesel engines
Had a 97 camry with the v6, changed the oil every 8k (kilometers) with synthetic. Never had a single problem, I live in a really cold climate as well.
97 Camrys are 1 million mile capable cars. most 90s toyotas are
Had a Lexus blew up at 45,000 miles they are complete junk. Stick to 4 cylinder Japanese cars.
Mike Vita I had 89 Camry with 235k on it.
Yep, same with mine. 1999 Camry XLE. I ran Mobil 1 5w30 at 5000 mile intervals.i sold mine with 350,000 trouble free miles. I gotta say it’s the smoothest engine I’ve ever owned
Ditto, had a Solara with this engine and the only problem it (eventually) had was with the knock sensors. Still miss that car, the engine, the (manual) transmission, wonderful compared to my FT86
damn that first toyota sounds fucking awesome
a nanen i miloshit ja qifsha
Right? That intake sound is cool af.
Good throttle response as it seems, too
There were factory supercharged versions that came out of TRD as well, I've only seen them on Camrys out of Australia
Reflex Photography NZ from what I've read the TRD Camry was also available in Japan and the UK (and NZ ex Australia) as a special order through TRD specialist dealers.
The only bloke I've met who had one got rid of it within 3 months, he reckoned it was too much of a handful to drive and I'm not really surprised when you realise it's a 300hp front wheel drive only car weighing 1500kg.
The 1mz-fe was one of the best engines made! Mine had 354,000 before I was rear ended and the car was totaled
yess!! Did you end up dealing with the knocks sensor issue? I have a 2000 RX 300, I actually made a RUclips video about the bypass and someone else did the same for the Avalon, but did this affect you during your ownership?
That boxer diesel sound omg 😍
i know it's not Japanese but a Peugeot 206 always melts it's ECu because it's in the engine bay
That Nissan fault must be a renault thing, they are essentially the same company, and they also have the same problem, the french like to toast ecu's.
Have you owned anything not japanese?
Vauxhall z engines suffer with this also
The Germans like to eat butterfly valves for breakfast, though.
SecondGear lol got me laughing
Disagree with the first one, those 3.0 V6 engines last for a very long time, my mom had one in her car and it had 300,000 miles on it and still ran strong.
Agreed I love the 1MZ
11094DEREK has decent horsepower and torque for the time being, the throttle response was nice and it sounded like an aggressive V6
My buddy has one in an avalon with 380000 plus on it runs fine.
KryptoOne22 had a 1999 Lexus es300 it blew up at 45,000 miles. Absolute garbage...
Dodge 318 Cummins what did you do to blow it up, you probably had a shitty version of that engine
I rarely comment on such videos.... The early QR25DE had a fault with ingesting catalyst dust... However, the newer ones did not have this problem.
I can personally vouch for the 1mz. It's a great engine but it is very sensitive to oil changes. Still, my friends dad went 28,000 miles on an oil change in his 2000 Sienna before the engine spun a rod bearing because of the sludge. Still not bad for a 328000 mile engine.
As usual, you have the BEST videos! Q: Why do you think the 7M-GTE had problems? Most of what I've read about this engine is that it is bullet proof, and withstands elevated boost quite well.
Great video and very enlightening. I have to admit when I saw the Subaru name come up I was questioning how one of those could be screwed up. They are such bulletproof Motors, but the diesel aspect that's something I never knew, thank you so much. I love learning new things that's why I watch all your videos. Keep up the great work!!
Solid example of Nothing is Perfect
a lot of engines before year 2000 aren't the most efficient engines. they tend to consume a lot of gas and didn't produce a lot of power but hey gas was cheap back then... engines featured here are just a ticking time bomb ready to blow.
2jz takes better beating from daddy than me
90s motors were awful, This is when computers got introduced and emission standards started to hit home
I knew the 7M turbo was gonna be in here and I knew how absolutely sexy that exhaust note is
For the Nissan QR25DE, it's bad years were 2001-2006. 2007 and up they fixed the precat and butterfly valve
@Tone. Totally agree, give me a VQ30 Maxima 5-speed any day. But I suppose there's a reason that Nissan was where they were that they needed to bend over for Renault in the first place, they must have been doing something wrong.
And they deserve a lot of credit for resurrecting the Z as soon as they could and keeping it going all these years, I can't deny that.
@Tone. Good thing the QR25 is not an engine from the Renault lineup then, right ?... Let's face it, the brand was pretty much ready to die, the deal with Renault is what saved their bacon.
Got a 2003 altima 2.5 with 250,000 miles on it stock
The Subaru 2L turbo diesel likes to split crankshafts in half. Very problematic engine. Has something to do with the boxer design which makes the crankshaft very thin at places.
True, but only euro 4 engines, not euro 5 engines
Yes indeef euro 5 has fixed this a bit but still not perfect, but there is some guy who is making stronger pieces for the boxer diesel.
If u ever need his name is nace king boxer diesel
Just rebuilt my EE20 euro 5 last year and there's nothing wrong with the cranks. It's to do with the rear main bearing failing and not supporting the crank which causes it to break. Why do the bearings fail because Subaru recommends the incorrect service intervals. These engines need oil charges every 10k I do mine every 5k not 15k and then people leave them to 20k no wonder they fail. Idots
@@reg4492 every 3000 miles
@@born2fap rebuilding a EE20 for a customer at the moment. It needs new bearings but the crank looks like new and it's done 200k km's 120k cave man mile measurements.
After doing a few of them it looks like the injectors start to wear at 150k which causes bad timing and hammer's the bearings.
Any other spec v owners see the title and immediately thing, "qr25de"??
Nathaniel Armstrong unfortunately, yes
A surprisingly good engine by itself though, once you get do a small amount of work to fix the two major issues. Mines approaching 200k and it hasn’t seen a truly calm drive in 60k lol
Mine I Change to mismo headers and Cold Air intake and All Pipes Under The Car and so Far so Good
I have an ee20 impreza for daily use, it's my second one tho (the first ended in a bush and was wrecked) the first one had 125000km , perfect, and the one i own right now has 138000km and nothing to say about that engine, everything runs perfectly
Cagibi Band honestly, almost any engine, when properly maintained, will run well. It says more about you than it does the engine
Just wait. It will blow up. I got rid of mine, My father didnt, his blew up on 218 000 kms.
The performance is pretty sluggish on the ee20 and they aren’t very fuel efficient so they are essentially pointless.
@@kungfusing1 i have an euro5 one and remapped it to 185hp with 410nm torque, plenty of power enough
woutti!i! Your a gambling man then I see 😀 Mines only done 50,000km so I can comment on reliability but if they are problematic in terms of reliability a retune will only exacerbate the issue not to mention possible dpf consequences. The power increases do sound tempting though as they could do with a bit more poke.
Any Nissan VQ35DE used in the 6th gen Maxima , 3rd gen Altima, or 3rd gen Quest
They are plagued with timing chain failures, catalytic converter failures, oil leaks, and oil burning.
Total garbage.
T 59 Wow... really? I always thought the VQ35 was a solid choice of engine... I guess I thought wrong.
I wonder what the root of those problems are...
It's not the engine as a whole, but only in certain vehicles. This is the same engine that is in the Nissan 350z, but it has no problems whatsoever. Different versions of the engine are present, such as the one in the Nissan Quest, which is horrendous because a few family members of mine have Quests.
Yes, it's the version of the VQ35 used in the vehicles I mentioned.
The same engine used in the 350z and Infiniti models are much more reliable.
Also the VQ35's built for the 7th gen Maxima and up are very solid.
Murano’s too... they are the worst.
Shanil Kumar that’s not true. Some 350z’s & g35’s had oil burning and timing chain issues.
Although, I like your channel and watch your videos regularly I will have to say I am disappointed with this one. Firstly the oil chane intervals on the 1MZ are there for a reason and it is a great engine which btw sounds awesome. And secondly the 7M-GTE apart from the improper torque spec on the head bolts has nothing wrong and can hold 500hp with the stock internals because it was overengineered.
Agreed, and just want to back you up on the 1MZ - I had a Solara with that and the E153 (?) manual, and that rewrote my idea of how a V-6 could sound. Pity the aftermarket didn't care, it was every bit the 6G72's equal stock.
The first engine was a great engine. I have a 98 Avalon, after 200,000 miles, the engine still sounds like a new one.
Ke Han until you actually drive a new one
I have a 99 240,000 that thing is quite you cant even hear the car on lol
Would have been nice to see engines showing the problems he described or at least screen shots of the faulty parts.
Do germany next
Senne C. The list is too long
4 vw engines and 1 by opel
n55, any mercedes petrol engine, opel, probally more i can’t think of
VW 1.9 TDI
Too easy
So I have a 7M-GTE story. An acquaintance of mine bought a 3rd gen Supra with the 7M, and then, being the cheapskate that he was, built a DIY boost controller from instructions he found online. Well that boost controller didn't work properly and put a LOT more boost to his motor than he was intending and it literally shot a connecting rod out the side of the block haha, but boy was it fast for a few precious seconds haha.
I have a 1985 subaru engine.. multiport, fuel injected, optical disty, knock sensor.. turbo. what was the first fuel injected again? I think it was mitsubishi that shared the new found optical disty with subaru... I never see the EA82 mentioned in good or bad or pioneering or anything. Someone tell me why?
I have a honda accord 2.2 ictdi diesel it has 350000 km and havent changed the clutch
I have had this engine in the Civic and it was fantastic. Taxes on diesel cars are skyhigh were I live so now i drive a petrol Jazz.
LOL the BMW 320SI engine . in the e90 those are made out of glass and have a rope made camchain xD
Thanks for crediting the videos! Loved the video.
Great vid, probably one of your most relevant.
I just love the old Starion with that engine maybe I am just oldskool that I want that as my first car :)
I've never heard of those problems when people look after them either. Only when people put 35 psi through them lol
I am so happy. There is no Honda engine in this video:-)
I'm curious if the 1MZ's sludge issues followed to the 3MZ. I have a 3MZ that just rolled over 245K miles today. The last time I had the valve covers off, you could have probably hosed them off and eaten off the inside of them. However, I do change Mobil1 every 6-7K miles and ran it since 10K miles.
That 1mz v6 engine is the one I have in my old Camry, as long as you keep the oil changed every 3 thousand miles they're pretty bullet proof and decently powerful.
The 1MZ, and 5VZ are among the best Japanese V6 engines ever made. Certain year 1MZ engines had sludge issues, due to Toyota moving the water jackets further away from the cylinders to minimize quench. I have worked at a Toyota dealer for 18 years in the shop, many 1MZ vehicles are going very strong to this day, they are much tougher than a 2GR. The 3VZ V6, and 2AZ 4 cylinder were among the worst Toyota engines ever made, Toyota will tell you that.
FunkyFresh48 I agree with you on the 3VZ. I was a Toyota tech too for a few years but if taken care of the 2az could be reliable. It had water pump issues but most people would drive it when the drive belt snapped or never change the oil. That’s what killed them.
GR-series engines also have an appetite for oil. There's a guy in Australia running a severely modified 2AZ on methanol running 9's all motor, and it sounds aggro as fuuuuuck
FunkyFresh48 my dads 3vz has over 600000 km and still going hes done nothing to the engine he never does fluid changes for ex he does a oil change every 3 years lol he beats the shit out of it and it just keeps going and going so.......
I have seen a lot of high miler 2AZ and 3VZ cars, I am not talking about individual examples. I am saying that the 2AZ and 3VZ have cost Toyota the the most monetary damage as far as engines go. That does not come from my opinion, or any bias, it's a fact. The 3VZ had a high rate of head gasket failures, the aluminum heads and iron block didn't like each other. :) The heads and block would expand and contract differently, causing wearing on the head gasket until failure. Many blocks had to also be replaced due to severe pitting on the block decks, caused by ECD. Toyota launched the V06 campaign for this issue.
The early 2AZ engines had an issue with the head bolts pulling the threads out of the block, the later 2AZ engines had a problem with excessive oil consumption due to dainty oil control rings, we can blame the EPA for that problem.
I currently have both a 2001 Camry with the 1mz and a 1993 Toyota pickup with the 3VZE and I'd say they are both great engines. My '93 pickup now has close to 250,000 miles (or 400,000mks) and it's still going, it's underpowered by todays standards but certainly not unreliable! I had more problems with Toyota 22R 2.4L 4 cylinder engines (which were easier to work on). The head gaskets were replaced under a Toyota recall 20 years ago on my V6. I have done some work on 3VZ engines and I can't say I like it but it doesn't happen very often!
If you want a not so good Japanese design, you could look at engines like the 3.0 liter Mitsubishi that I had in a 1997 Dodge Caravan or some Mitsubishi 4 cylinder engines which were even worse! I drove a low mileage smoking Hyundai Excel that had one of those to the closest junkyard and barely made it there! The car had 142,000 KM or 88,000 miles...
If the 1-fmz is NA why did it have a turbogauge standard on the car?
13utterz vacuum.
Yeah, I was wondering, too....That guage cluster is out of an SW20 MR2 Turbo (hence, the "boost" guage), but THIS one has the 1MZ-FE in it.
At least, that's what I THINK....
Possibly a TRD supercharged model, there are a few of those out there
Could have been swapped into an MR2 turbo. Which would explain why the boost gauge was pinned at maximum.
Custard1506 yeah it's 1mz-fe swapped mr2.
My dad has the 1MZ-FE in his Sienna... It has 370k miles and still runs perfectly. I was under the impression that they’re one of the most reliable V6s ever made. You often see them with insane mileage. How in the fuck is it one of the worst Japanese engines? I’ve seen it on best engine lists. Basically what you're saying is that it's a bad engine because people don't maintain them properly.
Your English gets better every day, keep it up!
Not one Honda motor was in this video, we Honda fans may be hated but at least our motors are made right 😅
TBills 3000 Honda diesels are pretty underwhelming.
I don't hate anyone. That being said, Honda still can't build a transmission.
My 02 civic was a piece of shit. Replace engine , clutch and other issues and still fucked up on me. I tried and really tried take care of my Honda. Just little bullshit issues ending up fucked
David Phongsavanh You're just a noob.
B Janak I'm a Honda fanboy, but I'll grudgingly admit that you've got a point there, at least for the v6 automatics. I've gotta tear out my auto tranny and put in a manual this summer.
Subaru boxer diesels were extensively modified from 2010 to adress the faults you mentioned.
El BU to no success. And their fuel consumption and power output does not really speak in favor of it either. A diesel subaru only makes sense in countries with very big price diference between diesel/petrol fuel, since the diesel model drinks as much as the petrol one.
waclosh not even close. The fuel consumption is one of the lowest compared to other diesels. Power output is normal, however power delivery is very different.
Got 8L/100km : heavy foot when hot engine , non aerodynamic 42" lightbar and 255 wide wheels+ full time awd, 185hp i say its not bad
@@waclosh How on earth do make that one out.
I just realized you’re pronunciation is getting better. I used to cringed a bit when u pronounce some words. Keep up the good work bro
The twin turbo G series engine was heaps worse then the M series engine.
The 7mgte was flawed but once you put an aftermarket head gasket & give the ceramic turbo & tiny inter-cooler the flick it honest works just fine & then you put it in your old school celica/supra in place of its 5m engine...
How is the 7M-GTE on here
ToyotaMR2 Fanboy cause it sucked...
ToyotaMR2 Fanboy I know right
ToyotaMR2 Fanboy it's such a good engine
ToyotaMR2 Fanboy I have one and I hate it 😂
I have no idea. Once you fix the head gasket you have a torquey turbo 3.0 i6 that can handle over 500hp on stock internals. Buuuut it's not a 2JZ mk4 so we're just gonna hate it for no good reason.
I'm just going to say that I disagree with a few of these
FoxFace same
Powerful engines can also be unreliable as well
When I was younger I had a Conquest TSI with a turbocharged Mitsubishi motor, a few of my friends had the same cars also. One of the fastest cars I've ever drove or owned. I miss that car and I love that motor. Parts were becoming scarce. If I still had it I would put an LS motor in it, and call it a day
I knew by Instinct that the 7M would be in this list lol
1mzfe are great engines you might want to do more research before you do these videos
Yea mine has over 450k miles on it and is still going strong .
He said that oil needs to be changed regularly. Or else there will be problems. Immature.
Best engine is the simple one...reliable /long life and easy/cheap to repair.
Thank you for putting the video of the 4G54B pickup truck in here, I have one and the engine really is the weak point.
My dad has a '96 Avalon, I had a' 01 Avalon, my mom has a '02 Avalon. All have, you guessed it, the 1MZ FE. They have all been reliable. I bought mine at 140k and used it for running deliveries for about 70-80K miles and of those miles I had been changing the oil every 15K interval with Mobil 1 Extended Performance (15K synthetic oil). The car did about 200 miles daily! Around 210K the engine had been starting to run rough and burn oil. Around that time I had to get rid of it as repairs cost more than what the car's worth. So I'm not sure if it was just on its way out or if it really needed oil changes more often.
I'm genuinely surprised, as a lover of rotaries, that those triangle laden boat anchors didn't make the list. They're cool, but goddamn are they shitty engines, lmao.
They just require very different approach when it comes to a proper care.
Most problems for a rotary come from people trying to treat them like piston engines rather than a manufacturer problem
Woodie 2714 you're dead right!! Also owners being cheap asses and modifying with cheap shit parts and no ecu!! Idiots! My 13b is at 610bhp and runs sweet as a nut!
VisioRacer even with the best of maintenance, most need a rebuild at around 60k for Apex seals
thedog556 not on my block dude! Don't generalise!
Next: German engines.
Top of the list: 1.9 TDI.
140 000km- turbo, DMF, clutch and actuator.
vag tsi blow by and timing chaing.
Merc M 271 4 cylinder - timing chain issues from 50k miles on
Skoda Octavia 1.9 TDI 100hp. 230 000km. Never opened the bonnet for other than normal servicing! 6 liters of diesel/100km
A little note for the "first Japanese fuel injected engine": the first was actually the 1975 Nissan 280Z. It used a Bosch L-Jetronic EFI, but it didn't use an O2 sensor.
Even though the 1MZ is considered a “bad” engine I put 350,000 trouble free miles on.my 1999 Camry XLE. I always ran Mobil 1 5w30 at 5000 mile intervals and never had any sludge problems
Not a single Mazda engine.
YES :D
Mazda embodies conscious respect and appreciation for what engenders passion and love for cars and driving
cause the mass majority are ford engines lol
*Rob Dahm heavy breathing* lol
@@shineything4444 wrong. Well, you're right about like a mazda tribute and the mazda pickup which is just a Ford ranger. But all of the other mazdas, like the 3,6, cx3, etc are all mazda engine. The first gen, I think cx 9 had a Ford v6, but they now have a mazda turbo 4 cylinder
The 2.3 turbo was utter crap
Personally, I feel timing belt cars are not to my liking. I would prefer cars with timing chains.
AMENNN !!! ! !!!
Timing gears >
And you have plastic guide issues on engines with Timing Chains. Especially with BMWs.
@@MidshipRunabout2 Yeah, But Only Because they Are "saving" Tooo Much !!! ! !!!
Who needs timing stuff when you can get a rotary which times itself perfeclty
I didn't expect the Mitsubishi 4G54B 2.6Litre 4cyl. made it onto this list as they put em in Mitsubishi light and medium duty trucks, industrial forklifts and early 1st gen Caravans just to name a few.
Gotta love that intro
QR25DE gets a lot of crap from flaws that mainly pertained to 2002 model year flaws. Its a good engine.
Solid engine, I drive a 2003 se-r and it's been running great with standard maintenance for a long time now.
My 09 Altima coupe has 220k with no engine issues. Knock on wood.
I've got a 5 speed 07 frontier just passed 300k original engine. Hasn't had anything other than normal maintenance hell my spark plugs have 100k on them
my X-trail had 230k's on original radiator fluid , only ever changed 1 oxy sensor and 1 cam sensor. Unfortunatly i was written off when someone hit me at 90kmh Very Reliaable engine.
you missed the D-CAT Toyota diesel, aka "i'm gonna blow my headgasket coz i hate you secretly and i want to make that absolutely clear". good list tho.
János Kun
I have no clue what engine you're about, yet I startled my cat laughing at the comment!
LMAO! The very 1st pic was a Starion/Conquest engine bay. I had one... It never stayed running.
Until I went MPI.
I would add the Mitsubishi 6G72 to this list. It was used in a ton of Mitsubishi, Dodge & Chrysler vehicles from 1986 to 2007. It always had a TON of issues with the piston rings that would cause excessive oil consumption and other oil related issues including engine failure. I could always tell if a vehicle had one of those engines in it cause there would always be a ton of blue smoke following it when it would accelerate from a stop sign or stop light!
Toyota makes good diesel engines; the 2002-2009 1KD-FTV 3.0 D4D used in the Land Cruiser 120 series i very good! It may not produce that much power (166 hp from a 3 litre inline 4) but it is the most reliable thing in the world!
or the 1HZ or the 1HD or the 1VD. he is so wrong saying japanese diesels are bad. the 1HZ is one of the most reliable engines ever made. there have been many in Australia that have done over 1 million kilometres without a rebuild
The 2.2 D-CAT was a mess from Toyota, despite the fact that it is producing good figures, especially for a diesel. The sealing compound between the block and the cylinder head was way too hard, leaving a mark on the cylinder head if this problem wasn't balanced and recognized in time while power loss, high fuel consumption and problematic electronics are also common problems.
The engines themselves were good but they were let down by their ancillary equipment. The 1KDs in the Hiace and Hilux models have a short lifespan on the fuel injectors and diesel pumps, and the clutch driven alternators have a fairly high failure rate, according to the auto electricians I work next door to. The 1HD 4.2L diesels are solid, reliable engines, but I've heard many cases of them snapping crankshafts when you put more boost through them. But you can't beat a Toyota L-series diesel. Utterly bulletproof, they do not die, short of running them out of oil
I guess him being European they never got the good diesel engines from Toyota. My parents have a 73 series Landcruiser with the 3.4L 3B engine. Huge naturally aspirated 4 cylinder diesel. Utterly unkillable. Japan definitely makes a lot better diesel engines than any European company when it comes to reliability.
Let’s see how many examples of Europe engineered Engines you will find - I think it would be nearly infinite
I don't think he meant it like that. I think he just wanted to talk about the failures since he's been talking about successes a lot. I think European engines are largely garbage. Too many of them are siblings (Ford-PSA being the shittiest offender) and the rest are incredibly expensive to service. I mean, I don't mind fixing or rebuilding parts but man it's expensive if anything happens to your Audi. Or BMW. I live in the north and I don't know if this is a thing elsewhere but Italian cars definitely share the reputation of Italian train manufacturers: they just don't start in the cold. Old Volvos make the cut. Some VAGs are ok. Would drive a Jag but only from late 90s. Saab used to be great I guess.
I came from East now in the west - It is simple - drive german cars til you have guarntee on them - beyond its just too damn expensive!
my uncle's fiat uno 1.0 fire carbureted used to start in -36c when we had such a cold spell in Poland when I was a kid, so i call bullshit.
now it's mine, the coldest i've tried it at was like -23 only. No problem at all.
If you know how to use the choke properly you're good to go.
I would add the mitsubishi early 80's 2.6 engine used in mitsus and dodge caravans and some others, horrible engines, 4 chains that stretched and if you didnt tighten them they would drag across the oil pump and ruin it, manual valve lash adjustment, rings that burned oil within 10,000 k, and a horrible carburetor that had 2 egrs. 2 sub egrs,(when they went you had two options go to the highest octane fuel or replace the entire carb to get rid of the knock and ping) a thermowax system double barrel but only one having a butterfly valve, and worst of all no step down high idle, it had a plunger at the end of a dead end coolant tube that would take close to 20 minutes in -20 weather before it went to low idle, made it fun driving on icy roads.
Wow your English is getting really really good!
you can't go wrong with Toyota or Subaru regardless 👌💪💯
Bruce Wayne yes you can
Toyota Echo
Toyota Prius
Toyota Yaris
Toyota Aygo
Toyota Solara
These are the cars that people with no taste buy, and in some cases just end up with. (For example the Echo, nobody willingly buys that car.)
Your friendly neighborhood Elite there's always something else in the same price bracket. people bought Toyota for a reason...
fanboy spotted
What is wrong with the prius elite?
The prius is designed to do few things.
Get you to work, Get you to the shops and Take the kids to school while being cheap to run
So is your hate because you dont like economical cars or is it that you see your favourite car being made into a hybrid and you want to blame the prius.
The First commerial hybrid was not the prius, that honor belongs to the Honda Insight.
Spinal Column I drive Subarus but I've owned a Toyota and I know they don't break. Lotus even use Camry engines
You forgot Toyotas 2.2 D4D! It has to be the worst diesel engine ever produced. Im in the used car business, and never have I seen one without its engine being rebuild/replaced after just 150.000km. It sludges, blows head gaskets, cracks in the engine block, EGR problems, turbos prematurely wear etc. etc.
Шевери Венто the toyota 2,5litres D4D is the strongest engine in my country some last 350k KM
The 2,5l isnt even in the same engine family as the 2,2D4D (AD), so I dont necessarily see what youre implying.
Funny now that you mention the brakes. Driven a few Corolla Versos and they always felt kind of "off" - say undersized, when decelerating.
Was talking with my mechanic some time ago while he was repairing one of those D-4Ds. Apparently a single injector for it costs over 800€
Lol ye diesel sucks but just saw one with +700 000km
Should have also mentioned the Isuzu 4ZE1. Between the badly set up engine compartment, the terrible fuel injection, and the bi-yearly head gasket replacments, I've not come across a more difficult engine.
at 1:08 ...SW20 Mister 2 Turbo (MR2 Turbo) with a 1MZ-FE in it?
Nothing is better than a vq engine.
squigga gtfo! Drive a 6th gen and after you have all of the problems it's known for you won't be saying that!
Zohan James Drive a 01 Maxima with over 178,000 Miles that has a VQ30DE, I have no Issues.
PON3Gaming i agree, the 3.0 is excellent! But the one that can immediately after, was where the problems really started to take shine.
Zohan James They should have kept the VQ30DE and just turbo it.
Mitsubishi 4d56 absolute joke of an engine drinks diesel like it's going out of fashion, produces as much power as a Vespa, crack heads for sport , leak oil no matter what you do to stop it and can't keep front crank pulleys tight which in turn damages the crankshaft a joke of an engine.
Higomad Exactly.
1:25 "Japan dont make good diesels"
Hino and Isuzu:"Am i a joke to you?"
Best diesel engines are probably toyotas
"Internals" not intervals when you were talking about the Mitsubishi engine sucking sludge into the intervals think you ment internals... Nit picking I know but your vids are great, long time subscriber keep up the good work dude
The Subaru is absolutly not the first diesel flat4, VW made it a long time before...
www.thegoldenbug.com/en/air-cooled_vw_history/d7/diesel_beetle
Wow, cool fact bruh
Lucas Rouer its the first diesel boxer engine. ....
flat 4 =/= boxer
Top 5 bad Soviet Engines!!Ohhh wait there's isn't!!
More like before the first oil change is due!
Jereby That's Soviet engineering for u my friend!!!I've heard it aswell!!
They last as long as the half life of bismuth
I thought that was a joke but now i realize youre serious. You wanna know what soviet engineering is? The planes they built to intercept the sr 71 had to have new engines put in as soon as they landed cause the engines would literally tear themselves apart at mach 2.
If you want another example soviet engineering caused chernobyl.
When you wanna comment saying that this list wouldn't be complete without the qr25 but then you finish the video and realize it was last 😂😂
I'm glad the Nissan QR25DE is on this list, one of those engines has been a pain in my side for years. Mostly because of the catalytic converter disintegration problem causing oil consumption.
Jake K Nissan KINDA tried redeeming themselves with the 2nd gen QR25 (in the 2007+ Sentra spec V, at least):
No more pre-cat problems (supposedly), no more butterfly valve screws coming loose......but still had the terrible rod-to-stroke ratio (which conspired to help keep its redline comparatively low). That big ol' stroke keeps its crank/reciprocating mass very busy at speed.
Still, mine is fairly "peppy" in the mid range....
Worst american engine next?
All American engines after oil crisis are crap. But the ones before are golden.
Ehhh... I not particularly a fan of GM, but it's pretty hard to beat the LS...
Too many to mention may need to make a 2hr documentary
The single worse american engine? That prize will probably go to the Chrysler 2.7 produced in the late 90's to mid 2000's.
2.6 chrysler...oops, that's a Mitsubishi 3.0 v6 chrysler.....oops that's a Mitsubishi gm dirty max...nope, it's an Isuzu
How about rotary? Renesis
SUPR VR rotary engine is a different story mate. Rotaries are amazing yet has to be taken care of well and obviously wont last too long. Id concider rotary a true petrohead's engine
SUPR VR they're not terrible. Care care of them and atleast hit the redline a couple of times you'll be fine.
Jordan Cook I couldn't disagree with you guys. If you take a care of them, they will be able to reach over 200k km, but let's be honest, this doesn't apply to Renesis engines (to year 2007). Renesis are the worst of Mazda rotaries.
I'll be honest, the 4 port versions that come in the 5 speed and auto models are down right crap. They can't reach RPM levels required to burn off carbon so they kill themselves all the time. But get one that revs to 9k and look after it and it's a sweet engine.
I was thinking about the renesis, the one in the RX8, that wasn't a good engine.
I like rotaries, I love brwap, but I think they were really unreliable and, in case of the renesis, one of the worst engines. The 7M is way better than the Renesis.
Please make a video on the Top 1 Japanese car design. Was there any? :) Letmethink - Lexus RC, Nissan Juke, Toyota C-HR, Infiniti Q70S, Mazda RX-7, Mitsubishi Space Wagon 1st generation, Nissan 240Z... some were.
I had a NON Turbo 7MGE that blew a head gasket at around 130,000 miles. It didn’t even warp the head. I simply put a new head gasket on it. Same with a Turbo edition I repaired. So evidently it was loose head bolts.
Not one Honda engine... Because Hondas don't die
Brandon R : Hondas never die, they just get new owners. 😂😂
The best honda
Unless you get one with an automatic transmission.
Lol so much guys are angry and trying to defend themselves
Yeah because he provides little to no evidence as to why these engines are terrible. Especially with the 1MZ FE. If you know anything about those engines, youd know that theyll last a life time with even minimal maintinence. The Camrys that they put those in literally do not die. Look anywhere on craigslist or whatever and youll see these things going for 3-5k with 100 thousand miles already on them. Those engines are 20 years old still holding their value and this fucker said theyre deserving of a spot on this list because of engine sludge build up like are you kidding me? He threw this list together with little to no research involved. Do you really think people arent going to get pissed about someone spreading mis information about great engines?
What is 100k miles dude ? That's nothing Even RX-7/RX-8 engines can handle 100k without a proper maintenance... and they are considered to be UNRELIABLE AF. You see, almost every non-downsized engine is going to withstand 100k miles. That's nothing hard to achieve tbh
Although I do agree that the video is done without a lot of research.
ManhartLOL I was low balling the fuck out of that because thats around what my car had on it before I got it. Im sure there people out there who run Camrys even longer without changing oil. But thats a bad idea because the engine sludge does become a problem. Its a toyota though. Of course it burns oil and builds sludge. That doesnt mean anything if you take care of it though because if you do, itll live much longer than youll need it for. My uncle has the exact same car except a year newer and hes at nearly 500k from using it as a daily driver and has had almost 0 front end or engine issues beyond normal wear and tear like torn axle boots or rusted calipers. (Minnesota)He runs cheap oil and FRAM filters too. I run synthetic and K&M filters so I should see even better life. The 1MZ FE is arguably one of the most reliable engines toyota ever made. And it has proved to be imo. Itll rip if you want it too as well. 194HP and 209 torque isnt slow. Its drones a bit but once you get it past 4k, she starts eating.
Yup, if you love your car and maintain it , it's just a pleasure to see it going another 50/100k miles, always. In EU the 1MZ engine isn't as popular though so I can't give you my own opinion on it. But I used to have the B16A2 Honda Civic along with 2 other guys riding literally the same models. Mine ended up going with me another ~100k miles ( With the clock before it being 130k) while 2 others didn't even reach 150k. The reason being though is the 2 other civics were used by daily potatoes, they just drove it and didn't care to maintain it. Some engines are built to be maintained and drive for ages and some are made for potatoes that just put in gas and run. Fun fact, my civic was still running perfectly fine when I was selling it and went for something more newew though. But if the guy will take care of that car he will run easily another 50k ( considering I've sold it for 1,5k$, that's a steal, lol)
ManhartLOL Yeah you can never beat a Honda in reliability. Theyre hard to find for sale at a decent price around here though because everybody has mods and shit. I got my Camry for $900 because it had a power steering leak. Granted the lady did want it gone because it was leaving stains in the garage, But it ended up being a $12 fix from the seals in the pump going bad so Im happy. I wish it was a manual though. The auto tranny is fast but eh, I wanna drive not just sit there and mat it lol
Ugh i really thought the EJ25sohc would be on here. I owned 03 wrx and a 2006 2.5i and i dont think people remember how TERRIBLE they are as far as geadgaskets and such failing. I mean, there are STILL ej25s being made today that the headgaskets blow out! Not to mention the oil pickups on early single cams being extremely prone to getting blocked due to a tiny clearance between it and the pan, even tiny dents are known to starve engines. Not to mention how dated they are, being they are still being produced, headgaskets and all.
I don't remember all the details, but many years ago I had a Mazda that had a very bad engine. I had to have it remilled, and it still didn't work right. it overheated all the time.
Built with chopsticks, not spanners. 😂
lol.
What about the Mazda 13B-REW? The twin turbo Wankel mills have a notoriously short life span.
They wont broke when smart people drive them
It's a crap engine. GOOGLE is your friend.
NuclearGrizzly Crap engine when you don’t know what you’re doing.
Creamy Meme Supreme Please explain? In your "expert" opinion how do you "know what you are doing?" lol
It's a crap engine. GOOGLE is your friend.
NuclearGrizzly You treat a rotary like a traditional piston engine and it’s definitely not gonna last long, at all.
love the 1mz. got one in my 99 avalon. despite the oil sludge issue its a fantastic engine with surprisingly decent power. to be fair , changing oil regularly should be done regardless if an engine is prone to sludge or not as this is good car care
I am surprised my 3vze didn't make the list. I get a lot of grief from people cuz i rebuilt the engine that wad already in my truck. Honestly just trying to keep it going. Im at 5k on the rebuild and its been fine. It does tick some up top and even tho i replaced the knock sensor it still says its bad and it misses some. Id like to swap it out one day but for now it gets me where i need to go whenever im not driving the subaru
Still better than american ones
there are lots of good engines here
And why? Do you got any evidence for your claim? Ironically in 2016 the most cars on american roads that reached 200,000 miles and more were from american and japanese car manufacturers with the Chevy Tahoe leading. Look it up if you want, but stop claiming stuff.
Ehh... It sort of comes down to what the maintenance costs were on those vehicles. You can keep ANY vehicle running for 200k miles, the question is, how much will it cost you to do so..?
Really?
id say america has just as many if notmore engines capable of running seriously high miles without major problems....buick 3800 and ford modular 4.6 run half million miles easy in cabs
GTFO MY 1MZ WAS BADASS
the car i drove in driving school was a subaru forester with that very boxer diesel. it crossed 300k kilometers easily.
I pulled a valve cover from a Toyota 3.0L and couldn't even see the camshaft there was so much sludge!
Honda = no problems
Burago Fix honda is garbage
Burago Fix... until you bring up their automatic transmissions. They SUCK.
Honda K series is on the edge of shitty. The make good power and sound but they need frequent oil changes, which many people don't do. So you get stretched timing chains and tensioners and the next thing you know the entire valvetrain is fucked.
So the engines are not crap but they suffer because of crappy maintenance.. Not a fault of the engine though..
Michal Stehnij . Not quite , if you drive deferent car for a white you will find out.
My Lexus has the 1MZ in it I think. Guess it's a good thing we check the oil a lot already.
Forgot about the Nissan YD25DDTI 4 cyl turbodiesel engine found in King Cab Navaras from 02-06. The bottom end siezes around 15k km if the crankshaft bearings are not replaced as they are underdimensioned.
Can concur on the 7M-GTE as the head-gasket trait is shared with its NA cousin. I had a wonderful 1987 Cressida before I knew about the problem those engines had with blowing head-gaskets. Guess why I don't have it anymore.
