I know a lot of stuff is missing which is why there is this comment section here. Since there is a lot more of reliable engines out there, feel free to mention your submissions and a little info about it if you don't mind. In case you want, I will gladly make another part of this series. Thanks you all for watching and have a great day!
VisioRacer the ford 4.9L I6. One of the all time greatest engines ever built. If you look up greatest engines of all time it'll be right there in the top 3 on everyone's list. Not to mention they are a gas engine which can withstand 500,000 to 700,000 miles without a rebuild.
VisioRacer you did a good job, however im sure if a north american made the list it would be a lot different. you had alot of european cars. Im glad you included the 1uzfe, probably the best small v8 ever made IMO. excellent video as always! cheers from Canada
Ford's 300 6 cylinder was a true workhorse. It was originally used in Farm tractors and irrigation pumps. A truly under-rated power plant that was gear driven with minimal issues.
David Harris My old man had one with over 400 thousand on the clock,with a cam swap,offy four barrel intake and true duals in a f100 and 3:50 gears it was a stop light warrior that would hang with or beat many v8 engines of the 70's and 80's.
You can get a newer diesel and delete the emissions I did it on my Chevy Cruze and it's ran perfect for a hundred and fifty thousand miles so far zero issues. Delete the emissions if all possible then you got a reliable long-lasting engine
@@AaronJohnson1979 i want to do the same because i have a lot of carbon buildup in my intake system. Its fucked up. One piece of that shit can destroy the turbo
I had a 1.9 TDI once. Bought it with only 45,000 miles on it...vehicle was totaled with 365,000 miles on the clock. It still ran great. If it wasn't wrecked, id still be driving it.
My 1997 Plymouth Grand Voyager Rallye with a 3.3L V6 has 406,000+ miles on the original engine and transmission. I replaced the rod and main bearings at 400k, they still looked new.
Everything on it works great except the original struts are squeaky and the self canceling broke off on the turn signal stalk. Have to remember to cancel my turn signal manually... :/
Oh yeah, Chrysler's 3.3 and 3.8 engine! My mom, when I was young had a '96 Grand Caravan. It dumped a trans at 140,000 miles, but the engine was perfect in every way!! It even sounded awesome with a hole in the exhaust, haha. I won't mention the fact it was super slow though.
3.3 had an issue with busting the #6 piston. It would just simply crack in two. Seemed like a hit or miss problem, though. Some of them did it, some of them didn't. I've replaced 3 with that issue over the years. And all of them around the 150k mark. I'd say if you made it past that, you probably have a good one.
Special EDy I just bought a 2005 dodge caravan with 90,000 miles well maintained and almost new how long do you think it will last? they use them as mail trucks here in Baltimore
Bobby McCray if it's been maintained, and you continue to maintain it, or should go for a good long while. It may have electrical issues here and there, but the engine and trans are great if you take care of it.
Some guy on another one of these videos (worst US engines) made the comment his was broken all the time. He must have been really hard on cars to break almost any inline 6 from the 60's.
I had a couple of slant 6 cars: Dart and D-100 pickup. The blocks would go forever. But I kept a box of carbs and distributors in the back of the Dart to keep it mobile. They were junk. And they didn't like to start in the rain.
I bought a solley single barrel out of a 66 slant 6 ended the carb trouble, bought a factory distributor gasket and sprayed my distributor with silicone to end my moisture problems
I have had a few Jeep 4.0 inline 6 engines with well over 200K and one with 300K with only regular oil changes. Inlines are naturally balanced and have 7 main bearings they are long lasting engines in general.
Not only do Jeep 4.0 engines rock...but they can be modified to put out a lot of horsepower without sacrificing longevity....(owner of three of them here)
We have had several volvo's with +500k on them. Hell, there are two registered & inspected daily driver volvo 940's with inline 4 (turbo and non turbo) on our yard, both at +550k on them. I even had that twinturbo s80 with inline 6 clocking 295whp and around 400nm. Engine was rock solid, transmission's 3rd gear friction plates gave out at around 460k. Any how, conclusion: Volvo makes damn reliable cars no matter the power output.
I worked at a truck shop, and someone brought in a 1993 Dodge Ram 3500 with a Cummins 5.9 12V inside. We replaced the starter and the owner said that was the first thing she has had to replace other than an oil change and a Valve and Pump Timing adjustment. It had 1,536,000 miles on the odometer, no B.S.. She drove it like a grandma and never was dialed up, she said that she has taken it to Pennsylvania almost every you since she has had it.
The Australian inline 6's from both Ford and Holden have extremely good longevity (especially considering our harsh climate), the engine specifically are the 202ci (Holden) and 250ci (Ford) :)
It still doesn't mean the modular 4.6L weren't extremely long lasting engine. All engines have their issues, but there's no doubt the 4.6L can go for a while, even with their faults.
Another EXTREMELY good engines are the Peugeot-Citroen (PSA) 1.9D, and 2.0 HDI from the same group, both used by many other car manufacturers and the Perkins based Barreiros C-24.
Love Volvos I have a V50 diesel estate for the last six years , I have just started having probs with the D P F though , that bit was a bit disappointing, it's done 141000 miles and has been serviced from new , it's a 2010 reg .
As a VW technician I would like to offer my input on the TDIs. The ALH 1.9L TDI (used until 2003 when it was replaced by the Pumpe Duse) is far more reliable of an engine. My own has 380 000 + km on it, and several of my co workers, along with numerous customers have over 500 000 - 700 000 km on theirs. The rest of the car typically falls apart before the engines do. The Pump Duse TDI (2004 and up) typically wear through their lifters and camshaft lobes by 300 000 km, have leaking tandem pumps, and the mechanical injectors are prone to failure as well. That being said, turbo chargers are rather expensive to replace on both models, and what usually kills a TDI is improper maintenance or turbo oil ring failure. Also, from personal experience, tuning your TDI, installing larger injectors and rolling coal will fill the variable vanes in your turbo with soot and seize the actuator up. So be wary of any of that nonsense. They're 90hp engines that make 48mpg. Not exactly designed for racing out of the box... hehe.
@@filippazourek5650 yes, even from WV there are SO many so reliable engines which have 300k km on average and its considered normal, but on this videos they just mention one and thats all.. the SDI is great example, i won 1.6 petron BGU, 300k km already and no issues meanwhile, this videos praise engines and consider reliable when its able to reach 150k km
I have a 4.0L SOHC V6 in my 1999 Ford Explorer and it recently passed 340K miles. It was a lease return and I bought it back in 2002 with just over 50K miles. All original except one head gasket began to leak coolant so I replaced both. Nothing else done except a light grind to exhaust valves since the heads were off. Over 100K miles since and still going strong.
TomsFruitStand agreed. one of my buddy's trucks is a 88 f250 with a efi 4.9l. we worked on it trying to give it more power for towing and failed lol. the milage of the truck was unknown since the odometer cable snapped long before he even bought it but it read 180,000 before he fix the cable. he beat the hell outta that truck but it never wanted to give up until he blew the slave cylinder in the trans from power shifting too much. he originally wanted to slap a turbo on it and see what it could do but life got in the way. great engines though for sure
TomsFruitStand agreed, my 96 f150 with a 5 speed gets about 15 mpg. That's about the best it will do. But it has 212,000 miles and doesn't burn any oil or coolant. I honestly can't complain.
TomsFruitStand Owned 3 Ford vans and one Ford pickup with the fuel injected 300 I-6. Lots of low end torque and economical with an overdrive transmission.
I'd agree those 2 are great motors!! My newer favorites were a Chevy 292-- Ford 302-- Toyota 22R---- Currently, I'm drivin 2 S-10s with the 4.3L---1 has 264,000mi--- the other 213,000!!!!!! Work trucks!!!!!
If you can find it, check out the Chrysler torture tests. Apparently they thought owners would haul a trailer full of bricks as part of their daily commute, and built it accordingly.
Antilaakeri any diesels that isn't in a Chevy or Ford lmao, my Mitsubishi diesel has more than a million miles on it and its never been rebuilt, has stock internals, and takes 30 lbs of boost
I had a 7.3. Wasn't fast, the thing loved drinking fuel, but the damn thing would pull a house and run forever. Never had a 300, but I know someone who did about ten years ago, and I still envy them, because it's still running strong today
The IDI version was even better. Great on mileage. Mine is sitting at 800,000k took it to a shop to get it inspected they told me no need to overhaul it just broke in.
A Nissan KA24DE or KA24E will last 500k miles if not drifted, turbocharged, and has the normal maintenance done. Mine is around 350k miles and just keeps going strong. 180+ compression on all 4 cylinders.
Great video. I always liked, even as a teenager, the inline 6 and 4 engines. They have plenty of power, are easy to work on, and hold up. Glad to see a number of them mentioned especially the Ford 6, the Dodge slant 6, and the AMC 6. Thanks.
I have a car with an inline 5 and I wonder if they are prone to warping like the inline 6. of course I know my engine is plenty reliable but in comparison there are many other engines outlasting it
@@planetx5269 it's a volvo c30 r design. It's got the white blocks. I've only learned about the older red blocks I'm starting to regret the purchase lol.
forgot to mention the Ford 300 cid/4.9L inline six. Their durability was the stuff of legend. They were so reliable that UPS used them in their trucks for 25 years and only dropped thém after Ford dropped the motor as an option in 96.
What about the Ford 300 straight 6? I have a late friend who had one with almost 400,000 miles and only changed oil and sparkplugs. Ford quit making them because they were too reliable (with a gear driven cam) and maybe possibly kinda got poor mileage. But definitely an honorable mention. Maybe you should make a part 2 Visio!
I have a 96 Corolla dx with the 1.8 4A-FE that has over 340,000 miles refuses to die. Just replaced the motor mounts and idles perfect and does not leak or burn oil with factory AC. Just needs a paint job. Daily driver 110 to 115 miles a day. Love this little beater.
@@jellyroll5247 1.8 4a-fe, interesting... 1.4 4e-fe, 1.6 4a-fe, 1.8 is 7a-fe, 2.0 is 3s-fe or 4a-ge. I have 4a-fe and this sounds better than new engines production and work culture is amazing! The sound of a ticking watch. Japanese all engine, and america works 1 engine on all life human. The 1 milions mile is no problem, on a good exploatation, and basic service, breaks, oil 10k miles years, filters.
@@furieux6742 if I got the engine wrong my apologies. As old as this car is people still ask me if I want to sell it. Funny, the guys that know, know. Just a well made engine and great A to B ride. I won't win any races but I won't be stranded either.
Any Volvo "redblock" engine is rock solid. If I would go on a drive around the globe it would be with that engine. Easy and straight forward to maintain. Easy access to all components (the few there is😂) Had a 740 wagon b230F with 600000km on the odometer. No engine issues when I sold it.
I can agree with this. Mine went through an owner that didnt know that oil changes were needed and still ran like a champ before a wiring issue for the fuel pump came up. Even then it still ran when we tested the ignition by putting a little bit of fuel in the intake
Exactly! Back in the day you can go to an auction and see 5 old police cars with the 302s and 4.6 for engines all over 500k and still purring like new!
I noticed there were no Honda engines listed, then I realized that's because if the list did include Honda engines, it would only consist of Honda engines.
I can say I got over 550,000 miles on my 1989 Jeep Cherokee 4.0... outside of just changing oil and replacing water pump on it the engine ran fine, the Automatic transmission was great as well and the four wheel drive was always good the XJ series is excellent... I never replaced the timing belt or chain... I do not even know if it had a chain or a belt... it had oil seal issues one time... it did die a honest death and I blame myself because I completely did a 100% maintenance on it draining every fluid in it and a flush... RIP... I killed it...
in korea, their’s suv called musso which has OM601 engine. i heard dozen of musso’s own by korea highway authority reach over 880000km with no overhaul, no major parts replace,
Peugeot might not be the sexiest name around but their older engines (I have no experience with newer ones) were tough. The 403, 404, 504 and 505 were some of the best. We've had 420,000 miles from an 1,100cc petrol 104, original cam and never had the top off. Peugeot 309 290,000 miles (1.3 petrol), 320,000 miles (1.9 diesel), 406 diesel 280,000 miles, 306 1.9 diesel 280,000 miles and counting. A builder friend had a Mercedes 200t Petrol 1983 that ran up well over 700,000 miles and still went like the clappers despite being driven hard its whole life. Most modern engines will top 250,000 provided they're maintained and used with a degree of intelligence.
Agree, my mom bought a Ford Fiesta Ecoboost lately, when I asked the salesman about swapping the timing gear he answered, that I won't probably ever swap it, because it's engineered for whole car's life - which, according to owner's manual is 240,000km.
I have got a 1995 306 1.4 petrol with over 560.000+ kilometers. No bigger issues, and nothing with that engine. Its get everything in time, i think it will run for more years :)
Agreed, I drive a 1998 Xsara Break with 1.4i KFW TU3 75HP, at 270.000 kms the engine's condition is almost like new, requires very little maintenance. Same engine as the Peugeot 306.
lonnie spangrud series 3 was the best, it had everything from the series 2 but was perfected in the end with fixes to all of the minor problems (lower intake gaskets) it's sad to see what replaced it. cough (3.6L) cough...
A lot of people don't want to admit this one but Honda's K20, H22 and D15 are also pretty reliable engines. with timing belt and water/oil pump replacements they can get to 300K without too many mechanical niggles. the only issue that stops them getting there is ricers and their *fantastic* knack for revving the tits off them until a rod flies out the side of the block, causing said ricer to be grounded for a year and have their weekly allowance taken from them and the whole car to be scrapped.
Best fords ever made was by the Aussies. I own a AU2 XR6 VCT. She is spotless and i hasn't let me down once 250k on the clock still pulls like a steam train.
Personally, I've had great luck with the Audi 3b inline 5 turbo. I've owned 3 of them and the highest mileage (91 200 20v avant) is somewhere around 380,000/390,000 miles (odometer broke a decade ago). Still runs like a champ. It has spent most of its life modified. It ran 12.1 in the quarter at 116mph on a completely stock engine (changed injectors, turbo, wastegate, exhaust, tune and fuel pump). Beside clutch, vacuum lines, coolant hoses and the occasional sensor they were problem free. Loads of fun!
I think that AMC knew that when they put the 4.0 fuel injected version into the 1987 Cherokee. Why else use an odometer that could register to 999,999 miles before rolling over? (The Asian 4 speed automatic they mated it with is also almost bullet proof. I have a friend who rebuilds transmissions and he has worked on a total of three in the last 20 years.)
As a mechanic, pure gearhead, racer, driver, restorer, and engine builder I agree with a lot of these. But I feel one important one is missing. The Nissan/Datsun L series. Those lil I-6 motors were almost indestructible. I personally put them through more than any motor should ever see. But I have heard many stories of the coming into shops for rebuilds at 500,000 miles and bearings looked good enough to reuse! Too bad the trans behind them were not as reliable. Anyway keep up the great videos. And I must say your English is getting better! Race On Brother!
Need advice please.... I'm looking at a 1996 toyota avalon xl with 80k miles and it is very clean in and out. they are asking $3000, is that a good deal? For whatever reason the KBB is less than 2K. Did you do transmission fluid flushes in your car? Have you used fuel system cleaner products like lucas in your vehicles?
The old Mercedes diesel engines have been known to run a million miles or more. Back in the day it was a W123 taxi not far from where I live who was running two shifts every day. One of the guys who used to work for the local Mercedes dealer said that the last time he could remember seeing the car it had 560.000 miles on it. The starter had been replaced once but other than that, and parts that will wear out like brakes other service items, it was untouched. It even had it's original exhaust.
I can attest i use to work in a lube shop. those 3800 gm motors are amazing. use to see taxis roll in all the time with 300-400k miles still purring like new.
The Australian Ford Falcon 6 cylinder engine. The big lazy six. Every one of them get 500,000 + klms. I have taken 2 of them to 400,000 klms over the last 20 years. I am on my third now, only has 190,000 klms on it, it is still a baby. Tons better than the Buick 3.8
I dunno about tons better than the 3.8L. I’ve seen a lot of 3.8L with 300k miles. The biggest killer of those engines is the Dexcool (antifreeze) GM used a number of years that would eat gaskets; eventually dumping into the cylinders while running. I wish those Ford 4.0 inlines were available in the states. If it’s anything like the 300 inline (4.9), it’s certainly a durable engine.
Paul Miles Ahh.. the great aussie steamer!! Pre crossflow very good. Alloy head crossflow and all the ohc ones do head gaskets at anywhere from 100 thou to 200 thou kms. I am a mechanic and can assure you many shops were kept in buisness doing head gaskets on em!! Hands up all those who have seen one on the side of the road with the bonnet up and steam pouring out... be honest...
The Volvo b230f is a realy solid engine! My grandad has one that sits in a Volvo 740 and have run 720 000km and still runs great! Me and My friends have Done regular oil and general mantanice and still runs like a clock
I second this for the B230F redblock engine. I owned a '94 940 with over 240k miles (which isn't that impressive compared to many of the mileage records mentioned in the comments, but still not too bad) and I currently drive a manual-swapped '89 240 with over 130k miles. I've seen B230s around me though with well over 300 and 400k miles
mine sounds like a clock factory and it's only done around 208 000km, it's making me miss the older one i had with a B200K (though obviously with a real carb.)
VampyrMygg well IF you service them regarly you can gett them to sound like factory new for like 500,000 km without eny Rod knock och piston slapp. But IF Its knocking now do an oil change. Mine (not My grandad) knock like cracy with bad oil. IT Will enyways hold upp to you Along time. Sorry for My bad english
Daniel Pfender Nice! My dad drowe a 94, 940 for a while with The b230fd engine. But My dad thoght IT was to slow so me and My friends turbocharged IT att Wi pressed out around 300 horspower out of that little engine. Sadly The engine failed but then we trogh in a om606 engine in IT. Now My dag have driven it around 600,000km. My hole family has long milege cars and there are still running strong:)
Chevrolet I-6, (The Stovebolt) any displacement. Chrysler Slant-6. Ford flathead V-8. 327/350 Chevrolet. Ford 300 I-6. Cummins 6bt. 7.3 Powerstroke. 389 Pontiac. 289/302 Ford. Chrysler 318, 440. AMC 401. Oldsmoble 350.
I don't believe that changes the fact they are reliable engines. Getting abused in a good way is beneficial for an engine - you need to stretch its legs once upon a time.
VisioRacer True but it depends on the car type and when it was made as you said. New cars you don't really need to push and obviously you shouldn't really ever redline something like a suv or van but you should with like a sports car.
you need to look into the dodge slant sixes. While i was teenager working in a garage we had a guy come in with a rod knocking, he drove from NY to Oklahoma on it and i told him to keep oil in it (he was on his way to California and then going back to NY) and it would make the trip both ways. He called me later from NY to tell me he was back home in NY and was going to have the bottom end fixed and it most certainly made it. I went to a car event held by a mopar club where they took a swinger with a 225 slant 6, drained the water and oil and sold tickets on how long it would run, best guess got the kitty minus 20% for charity. It ran 27 min 16 sec before it seized (didn't even through a rod). I've seen many of them with 500,000 miles or more. Great engines.

I would have to disagree with the PD TDI engine. I have a Jetta with a PD motor with 225k miles on the clock, but it's had the camshaft replaced twice, as it was a poor design. I also have a Jetta with a 1.9 ALH TDI at 305k miles, and still runs strong! better than my PD TDI.
I think the 300 cid or 4.9 litre Ford inline "6" should head up this list. UPS used this engine exclusively as long as it was made. 300,000 miles was nothing for these engines. They easily surpassed that if kept from overheating, over revving and the oil kept clean and with sufficient oil pressure. That said, MOST engines will go a lot of miles IF they are taken care of. The Ford 4.9 litre had the advantage of gear to gear timing, no chain. And it was designed not as a vehicle engine, but as an industrial engine, which Ford used as a "temporary" solution when needing a bigger "6" for the F series. It stayed around a lot longer than envisioned. BUT, there were some TRULY horrible engines built. The all aluminum Peugeot in the 60s a prime example. Better a chain, sprocket and pedals than that in your car. With most though, take care of the engine and it will take care of you. **caveat** There are "lemons". Odd man out if you will. A thousand good ones, but if YOU get the one lemon the bad taste never goes away.
The 1.9JTD and 2.4JTD engines on the Alfa 156 are also know to be extremely reliable VisioRacer, one of my neighbours has a 2.4 with 710k km's on it, and my mechanic has another customer with a 950k km's 1.9JTD, i have one as well with 190k so i hope to do many more miles on it!
The problem with the early versions of the fire engines back between the 80's and the 90's was the head gasket, on many models (like the Uno or the Punto) it worn out by 100.000 km, and it would let cooling liquid get into the heads. I actually had a 1991 Uno, and by 136.000 km it already needed a new head gasket. Otherwise, the engine was still running fine before it started developing the issue, and i was told it's running great now as the head gasket has been replaced (i sold it). Most of the time on said models, the gearbox gets you more issues than the engine itself, even by less than 100.000 km.

Diogo Simão i had Punto 1.2 1994 and it was like you say.. the head gasket leaked oil into the coolant. if the Punto wasn't so rusty, i wouldn't give it away.. it had about 180k kilometres..
If they leak oil it's usually not just the head gasket i think, but the piston rings maybe. Head gasket wearing leads to water leaks (as far as i know).
+VisioRacer You forgot the 1.9 naturally aspirated 1.9 D from Peugeot ! It has only 71 hp, 125 N.m of torque but is a reliable and basic diesel engine, which can do 500k km!
We had a Skoda Superb with a 130hp 1.9 TDI engine (2005) and we drove over 450.000km with it. We got rid of it because of several minor things on the car, but not the engine. Now it is still going strong somewhere in Poland. Also, you can say what you want, my dad didn't drive it like a hoonigan, and he knew the car very well. But ofcourse, not everyone with a 1.9 TDI drives it like we did...
mikkei and another hater... the mechanics guy in Poland checked the whole car, repaired the minor things and replaced what needed replacing. Can't wait to see it in a bad driving video :)
I hate I think- cause your country doesn;t have a car history like MOT in UK , And If you find a car from abroad you always didn;t know that is a true millage of this vechicle.
I think he wanted to say that the car has been sold to Poland with 450 thousand kilometers, but the 1.9 TDI engine in Poland is so popular the dealers (private sellers sometimes do it aswell unfortunately) turn the mileage down to about 190-220 thousand kilometers so they can sell it easier with a higher price, this is very common, and the goverment/police/anybody actually doesn't do anything with it, for an example, in Germany you'd be in jail for something like this. Your car's mileage was normal, but seriously, would you believe in a 12 year old diesel to have 200 thousand kilometers ? ;D
Not to mention the opinion about the 1.9 TDI, people now think the engine is shit because they brake after 200k kilometers, most of them are above 400-500k kilometers now.
Gee whizz, I can't believe the most durable American engine ever made had no mention. The 4.9 L 300 cod Ford inline 6. First made as a industrial engine, then used in F series trucks. Indestructible as long as the owner changed oil & filter regularly and changed antifreeze every 3 years.
Mark Capps my first truck had this engine. I was not nice. Literally has not seen more than a plug wrench since it was outfitted with a homemade air cleaner in 1980. My grandpa said it ran a lot smoother after it inhaled some mt. St. Helens ash. Honestly probably gave it a good cylinder wall polishing lol. It now sits with no third gear but grinds around the farm every now and then in first and second with a solid 410 thousand on her.
No kidding! No question the Ford 300 I6 was the longest lasting gasoline engine ever put in a passenger vehicle. Only engines I'd say would last more miles are the big slow turning diesels in the over the road trucks. The 300 I6 was the longevity king! Ford just couldn't meet newer EPA regs with it, so like all great things, it had to come to an end.
@@patrickjaegers3110 I had one in a Bronco. The engine outlasted the vehicle. We pulled it out and ran it for another 10 years in a truck, then took it out and ran a sawmill 10 hrs a day, 5 days a week for another 10 years. Finally it threw a rod through the block.
@@bigdogpete43 Yep, they were near impossible to destroy. You might be the only person who ever used one to its full potential that actually wore one out. 10 hrs a day for 10 years! That's awesome!
As much as I dislike our fords I give them respect for lasting so much even if the earlier engines prior to BA got serious bore wear issues before 200,000km, they still ran to a million km with bores that worn out long ago. They just go and go even if they are always on their last legs. Pretty amazing really.
Never heard of bore wear issues with them, my old EL Falcon did 350,000 kms without any significant wear or loss of compression. What eventually killed it was blowing a welch plug out of the block on the freeway and cooking it.
Its not something you see or notice until you remove the head and look. Thats what I mean is they seem to go fine despite wearing out quick. I had this issue on about 9 engines with in the family and some friends (all blew gaskets so I saw the bad bores repairing heads and retrofitting them to MLS gaskets) . My bother's EB had one where the pistons had worn and turned into the bore at an angle of about 5º. It has 0 comp on that cylinder understandably. Its just the nature of their design given they are massively under square and have a lot of piston side load and the pistons are low silicon making them have more anti scuff properties which also makes them have a high expansion and contributes to low temp wear due to excessive clearance before they reach operating temp. But that low silicon alloy is what make them reasonably good at taking boost with detonation shattering the pistons. I'm not sure what the BA and onward are like as we only have 2 fords left in the family, 2 BF utes and they never needed the heads off so seem to be really good. Rest of us all have Buick v6s now and one 5L VR ute. I can tell you the 5L sucks for reliability, not the engine itself but the ancillaries and gaskets other than the head are crap as they are with the early fords. Buick coupled with the T5 transmission on the other hand is absolutely flawless. I have done documented tear downs on some of my highly abused high mileage engines which I put nearly all the mileage and abuse on them and its incredible the low wear rate and no signs of damage. I
Those 1,000,000 kay cars/engines were probably taxis. Its not just ford engines that last well in this usage . the telling factor is operating temperature and maintenance. Engines in taxi usage run for long periods at the correct operating temp - the clearances are kept right. It is start up and running at low temps that kill an engine fast.
Believe it or not, Range Rover Evoques are notorious for breaking down, but my parents sold theirs to my uncle and it has 200K miles on the clock and it's still going strong! Runs like the day it drove out of the dealership! Never had any issues on it whatsoever. It has a 2.2 Ford/PSA Duratorq 4 cylinder.
Mercedes now holds the number 1 title of the most unreliable vehicle followed close by is BMW, the once awesomely engineered German cars are now rubbish for reliability.
The engine's are only as good as the maintenance applied to them. They won't get over 500k just because of their brand or type etc. Any engine will spit the dummy if you don't look after it. One person gets a million miles on his engine doesn't mean they all will.
Volvo B18 and B20 wasnt really that great stock, the B18 in particular was plagued by very cold thermostats, and all of them leaked from the back of the crankshaft until modified with a modern seal. One of my -65 B18D survived almost 200k km with the original seal but by then it was already spraying out oil through the seal, also B20s i had did this at high speeds, if i was above 110kmh it used almost a litre of oil a day. Sure they can run 300k km but not without a new hotter thermostat and seal. B19 and B21 can however, i had 100% original engines going past 600k km, only change contact points, spark plugs and oil. B18s cant do that in their original configuration.
I wonder how anyone would want to drive 300k+ in the cars these engines was in. Driving a car should be a pleasure, not a workout, and the P1800 was the only one I wouldn't had to hide in a dark corner if I owned one, the others where hideous.
