Yah know, Eric, you do always say, "...even the criticism..." Dude, there is nothing to criticize. My wrenching days are long over, yet my Saturday evening is would not be the same without an I DO CARS fix. No dissing, only kudos. Thank you!
This is what would make me the most nervous about buying any vehicle with these engines. Timing guides failed on these in the past. I can't imagine the cost of a full engine out repair.
All of the "technology" already exists. Cam in valve cover. Fuel pump in valve cover. Rear timing. Water pump behind timing cover. Wet timing belt. Boom, you're pulling the engine every 60k. Awwyeah. Ford will probably do it first, if their recent abominations are any indication.
I love how I can just come sit down with my Sunday morning coffee for video upload that's just NICE. No shouting, no drama (except throwing shade at manufacturers), just some relaxing wrenching
Hey so I actually service BMWs almost exclusively here in Charleston I own JU Automotive. Where you said that the oil filter housing wasn’t the cause but the affect of overheating I can almost guarantee that it is the cause of the overheat. They typically break in that spot and do cause overheating and sometimes mix oil and coolant or vise versa. Love you !
Some questions for you: (1) how frequent is the injector issue where they could hit collide somehow? (2) do you think the plastics in this engine will fail like past bmws from heat cycling? (3) what are odds someone will need to get to timing components before 200k miles?
@@neilquinnI only have knowledge on diesel powered BMW engines. 1) Injectors on those are pretty sturdy, a bad injector happens pretty rarely in my experience. 2) The plastics on all the cars will eventually start to deterioate and break/crack, in my case on my F10 530d I had to change the plastic coolant tube that attaches on the left side of the head, that bastard was shooting coolant all around (everything's fixed now). 3) Timing chain should last 200k miles or a little more, but you'd have to consider changing it earlier than that, I myself have 245k km / 150k miles on the odometer, haven't yet changed the chain, timing system looks to be healthy. Regular oil changes help reduce the risk of timimg related issues - I change oil every 10-12k km (6-8k miles)
That's my experience with E30s too. But then that's almost the case with old cars I've had. I've replaced radiators, water pumps, thermostat, cooling and heater core hoses on my 30 year old Celica too. However I can say the Toyota will run without issues despite having coolant leaks compared to the E30 325i I used to drive.
Automotive Engineer for Honda here. Those BMW motors are pretty solid. Toyota uses them in the base Supra. The rod bearings looking like new at 100,000 miles kind of proves that. BMW makes some great engines. It's the emissions regulators and accounting teams that force us to use plastic cooling systems. It's not just BMW. If you don't replace the cooling system at 100,000 for any car past 2008, you're on borrowed time.
I agree that the metal machined parts of this B48 engine look rugged and extremely well made and machined. Lots of savings could be made by making things less well and still last well enough. But no, some dinglebunny accountant comes along, you claim, and tells the engineers "Ve must sev 5 cents by using a plastic water pump impeller". Right, that and three bucks will get me a cup of what passes for coffee these days. Makes no sense no matter how one looks at it. Emissions? A water pump impeller made of plastic that lasts forever in a dump, if not in the engine. A metal one is easily recyclable. I look at that "oil cooler" and see O-rings tortured into crazy shapes on the block used as oil "seals". Suddenly, German rationality is ditched. Look at Honda screwing the J35 with DI, using $3 injectors that fail at 50K miles, as South Main Auto has shown. Honda sells a cheapo six pack even at its dealers for this "wear" item. Plus who knows how much labor to replace them, when it's only a 30 minute job, according to happy mechanics reporting in at beating the book rate by a country mile. Hell, the timing belt lasts twice as long. I've seen accountants at work, and they generally come round to reason, and blaming "emissions" for use of plastic parts is pure hogwash -- nothing, I mean NOTHING, to do with it. Discarded plastic in landfills lasts for ever,; scrap metal is easily recycled. You're not getting your excuses past me, I'm an engineer too. I mean, even the most cost-cut engine I've seen here, the Hyundai 1.6 turbo, made out of spider webs and 1 mm thick alloy lasts 100K miles. So these robust BMW engines have to have built-in failure points -- on purpose. Same with everyone else. Otherwise we have to assume engineers are all Jekyll and Hydes, which is absurd. Like running rubber toothed belts in oil at Ford and VW, and those useless DI injectors at Honda. Or VW using expensive special iron on their otherwise dog's breakfast of a 2.0 liter turbo four. That's the stupidest mechanical design I've seen torn down on this channel -- a complete nightmare. Much as I hate to agree with Internet opiners, I see a conspiracy to produce junk. 95% good, and then crap that will obviously fail. Not the way my mechanical engineering career went, but it wasn't in automotive which seems like scam city.
Toyota/Lexus UR, GR series entered the chat. Not trying at argue with an engineer but this is to prove your point that some companies accounting teams are interested in using higher quality rubber hoses and not using plastic water pumps, like Toyota, Honda, Mazda and Subaru. Maybe even Mitsubishi although it is a dying breed.
@@Methylphenidate2803 Oh how naive you are. Toyota/Mazda/Subaru are all using the same cheap processes. It's called injection 3D molding. No company is using plastic water pumps as of 2009 either. What they tried is using plastic impellers for a while. "Higher quality rubber" is so painfully incorrect. All manufacturers such as BMW, Toyota, and whoever use the same quality rubber". Generally, quality companies like Continental will make the hoses. The big differentiator is that a performance car tends to run at higher temperatures naturally. Your average Toyota is tuned to underperform generally compared to something like a Camaro SS. Thus, it will make that rubber last a bit longer. Finally... You should really be replacing these "high quality rubber" parts every 8-10 years on any car. Not doing so means you aren't too knowledgeable on how a car works and are on borrowed time. Gaskets/hoses/etc. degrade with heat and lose mass. It wasn't until the last 5-7 years that new materials were compounded to better tackle this issue, but those are all aftermarket. This is one of those moments where it's better to remain silent than to speak and assure someone you are not informed.
@@BillMalcolm-tn3kq You're not wrong. ALL companies are 100% taking shortcuts. I blame it on regulations and greed mainly. The US wants 70& of a car to be able to rot into the earth environmentally after its use. What does this mean? It means corn-based plastics and shortcuts just to be able to produce a car.
Dude! My wife loves to listen to you in the background and watches all you're tensioner and water pump shenanigans. Today she has suggested that you need a clear safety tote (she even gave it a Rev 3 designation!) for your convenience. She actually has learned a ton about engines and to my surprise has even spoke about engine topics while we're driving down the freeway! Keep up the great work!
Give me my 2004 Lincoln Town Car 4.6L 2 Valve. Three or Four years ago I had the mandatory heater hose nipple break off on the interstate. I lost all coolant. I only noticed when power reduced as it went into the "Air Cooled" mode running on 4 cylinders and 4 pumping air. Got it off the road safely with reduced power. I had the intake and hoses replaced, refilled coolant and that is it. Total repair was $600 done by a professional mechanic. it is now 20 years old and 225,000 miles. No check engine lights. Drives and looks new, only the drivers seat gives its age away. Ill change that soon enough.
I like your balanced, factual, philosophical, non judgemental theories and conclusions when summarising the probable reason for the overall engine failure. I'd say manufacturers could learn a lot from your teardowns, it's often hard to predict what will fail when designing an engine and easy to apportion blame after the event. That said, the use of plastics, for whatever the reason, appear to be the weak link most of the time. At least this engine appears to be much improved, when compared to previous versions.
I know right! I was mentioning the snac paks every video cause they're sitting there ever single video, but he never responds! Eric, oh Eric, why for art tho pudding pops sitting there for eternity, week after week there they sit. On a crowded engine-filled set of shelves, sitting out of place, lost in space! 🚀🤦🏻♂️🥄🥣🤔😂
I saw a drift race engine builder use the side of the engine to mount it to the engine stand. Used an adapter plate like you would for the rear but setup to use the motor mount instead
I really want to thank you for your videos. It's very relaxing to watch your videos at the end of a hard day of work. Again, thank you so much. God bless you and your family
I’ve had 5 BMWs from a 1996 535i and to the 2015 X5 with the 6 I’m driving today. I’ve only had one give me trouble on the road. A 2000 323i that gave up its alternator at 235,000 miles. I think it’s to be forgiven. It sounds like some of you guys have had bad experiences but I really haven’t.
I would love to see you tear down a 2.4 SRT4 that came in the 2003 Chrysler PT Cruiser GT with the aluminum intake. If you can get your hands on one. Great video as usual.
An engine condemned for a blown head gasket. In my day (60's and 70s) that would have been $100 to $200 to R & R the heads plus $80 to rework the heads. (New valves and springs and milling the head level. The only way we would throw the engine away would be if the block itself was warped, extremely rare.
The problem is that these small displacement turbo engines have a very high specific power output so there is LOTS of pressure and heat involved. When a head gasket fails it’s usually pretty cataclysmic. I lifted a head on a late-model small turbo motor from preignition and it ended up spraying coolant right out of the side of the engine. The scary part was that once things returned to normal the bolts still had enough tension to allow the steel shim gasket to seal and it even passed a compression and leak-down test. But, the reduced bolt tension allowed trace amounts of coolant and exhaust to seep by, which eventually would end up trashing the engine due to coolant contamination and rust. If you catch it right away it’s fixable, but by the time it gets to this point, it’s cooked.
sure, they were ruggedly simple...and that's about it. Not necessarily powerful unless you had a swimming pool worth of displacement, drank through tanks like no ones business, and many still weren't even all that reliable. Many vehicles past the 90s, specially many Japanese ones, will gladly eat up miles upon miles. Hell, even my old BMW got beaten on daily and had over 160,000 miles on it. Engine purred like a kitten and pulled smoothly. This all comes at a cost. You can't just fix modern cars in your backyard like you could back in the day.
As always Eric, thanks for the Saturday night entertainment. Happy Memorial Day everyone, and thank you to those who paid the ultimate price for our freedom.
They just keep making engines more complicated than they need to be, and having the timing system at the BACK of the engine, is a real a**hole move. Not to mention the over-use of plastic parts where they shouldn't be.
Even Caterpillar and Isuzu is doing it now on large L6 semi truck engines, not to mention using a belt drive oil pump in the engine. It's planned obsolescence.
Timing BELTS running in oil is probably the single worst trend in modern engines. Using plastic for parts that should be metal is just a tick behind. Failures from these two happen regardless of how well one maintains the vehicle. Sad.
Engines designed to eat themselves right out of warranty, so people have to buy a replacement. Makers just don't believe in quality anymore, only volume and profits.
@@billgraff4809 Well, the BMW M52 and any other Engine of that era used plastic chain guides and they rarely fail. The ones I pulled from a 2003 M57TU engine with 330k km were in pristine condition. A bit more on the brittle side than new ones, but after 20+ years of permanent heatcycles, i think thats okay. A friend of mine has currently 600k km on an unopened gasoline engines, still runs strong. Plastic guides DO work, when the chain and guides are well engineered.
The turbo heat cycles on that engine warped the engine block, it's common on all turbo applications where the turbo is directly mounted to the center of the exhaust manifold.
Amazing, sunday morning coffee, it was actually a boring teadown, but you made it entertaining anyway. This engine looks like it should have been rebuilt with a head job in the car.
4:05 - Stephan Papadakis did a whole build series on his B58-powered drift car quite a while back, and he welded up a bracket for side-mounting the engine on his stand. It seems like the only safe way to do it while retaining access to the timing chain components.
My neighbor bought a 2019 X3 with 60k miles and kept it for only 6 months because it already was having major problems. BMW made phenomenal cars in the 80’s and 90’s. They make unreliable status symbols now for people who think having a lot of debt and getting a loan on a some they can’t actually afford somehow equates to being wealthy.
My 2018 B48 had NGK's from the factory. When I replaced them with plugs I bought from a BMW dealer, they were Champions from France. They might be replacements. IIRC the replacement interval is 60K miles on most B48's.
Another great episode, Eric, thanks so much !!! As an old fart (real old) I'm amazed at the complexity of today's modern engines. And to me, so much unneeded complexity, and all for what? Increased power, fuel economy, etc??? I'm just stuck in the past, I guess, and reminiscent of the multitude of American small block V8's (trouble-free) I owned and drove the bejesus out of, from shore to shore.
I love the new engine parts hardness tester! Also I think that the move to rear timing chains is for added revenue on the service side of the dealership to make up for slow sales maybe?
x pattern is called honing. It's done in the factory so oil sticks to the cylinder wall better. If used motor still have it it's a good sign. It means it's not worn out and well maintained.
I don't know who BMWs material scientist is for gaskets, hoses and o-rings but he has been working for them for about 30 years now and he settled on the self disintegrating stuff in his first week and then put his feet up on the desk
We sell these quite well. The fwd engines are more expensive than the rwd versions. The problems i usually find are blown head gaskets and cracked pistons. If there is a loss of compression in one ir the cylinders then you have a crack in the piston between the rings.
Looking at the the build quality being much better than that Subaru engine you recently tore down is interesting. Unfortunate that BMW uses cheap plastic for their cooling system.
I was once told that European cars used “bio degradable” plastic engine parts vs “recyclable” plastic parts on other brands. Might be true: on my M54 Bimmer you WILL replace the coolant expansion tank every 60k. Or else….. Meanwhile my ‘11 F150 Ecoboost went 160k on the original “de-gas bottle”, it being strong as day one when I traded it.
The oil filter housing being plastic was most certainly the cause of the failure. And for less than $100 you can get an upgraded all metal housing from multiple aftermarket sources to prevent this problem. And so could BMW for that matter. If they cared.
From all the crusties on the water pump and elsewhere it probably ran low on coolant which is what doomed it to failure. This is alluded to by Eric’s comment on the thing basically being the Sahara desert inside. While the metal housing will do a much better job of circulating the exhaust gasses that have taken the place of the coolant without melting, the outcome would have probably been the same.
I have a couple of cousins that live in Germany that are BMW enthusiasts, when they have noting better to do they drive their BMW's but when getting somewhere counts they drive something else (an Audi for one and the other has a Mercedes) neither of them use their BMW's as daily drivers. They also have a slightly crude nickname for BMW in Germany that translates as "Bavarian Manure Wagon".
@@danielorozco1728 Because the high strung twitchy engine that revs real high but might explode is FUN, but a boring old Toyota is going to get you where you want to go every single time.
Then they're kind of less of an enthuziasts. I myself drive my bmw as a daily. Averaging 3-4k km / month with my F10 530d xDrive. Fixing whatever needs to be fixed while I'm in garage or I'm in a pickle while being near parts store. One "Pickle" situation happened because of the plastic coolant tube that's attached to the head, 40€ and 3hrs on the side of the road and now it's running great, no coolant leaks.
@@luckgrip252 I own a e92 N55 BMW and drive it almost daily, cars are meant to be driven. I guess you're german? The problem I have is that here in Mexico there's no one that truly deeply specializes on BMW engines, so I have no one to directly ask for advice so I have to watch videos and forums, hoping there's nothing too complex that I cannot do myself. Anyway how much do mechanics know about BMWs where do you live, mate?
I worked on a B48 a couple weeks ago at work, lady complained of coolant leakage. Discovered it was leaking from that topmost gasket on the oil filter/cooler housing. Also the GFRP on the housing had broken in the same place too.
Painting the engine vs putting a tag on it: I’m thinking that it’s because it’s easier for a nefarious character to take the tag off than to take the paint off
Good to see the condition of the internals on this B48, as I have one in my 2018 MINI Cooper S. Well, actually mine is a B46, but they should be the same, right? At 50k miles now, no issues whatsoever, and it doesn't seem to burn hardly any oil, maybe 1/2 quart of RedLine 5W30 Euro TD oil between my 5k oil/filter changes. I just switched over to Mobil 1 5W30, so we'll see if that continues. The B48 timing chain location definitely had me a bit frightened, as the timing components on my 2011 N18 MINI Cooper S were supposed to be rather weak, although mine seems to be fine at 127k miles now. I did have a head gasket failure on my N18 at like 88k miles, combustion gases into cooling system (much like the failure on this B48 you tore down), but that was on me due to not correctly bleeding the cooling system after a coolant change. I couldn't find a local place to resurface that head, so I bought a good used 38k mile head from a Euro auto salvage joint, all new BMW gaskets and such (no timing components except the upper chain guide and the TTY bolts that needed replacing on the cam gears etc.) and all has been good since then. Thanks, Eric, for the great tear-down videos! Keep them coming, man! Take care, and stay cool.
You know, I think I would really like to see you tear down an old flat head. I have several and am about to learn how to work on an engine with them. Would be invaluable - especially to see you try to get a distribution tube out of a 50's dodge.
I know someone with an n20 with around 100k, 12 years old out of an x1 automatic. The timing chain / guides was replaced under warranty before it had issues.
On the subject of "noooo don't tear the bottom end apart!" - I would be very keen to check and have a machine shop check and re-deck the block, which needs all the rotating assembly removing to do. The block likely isn't warped, it's usually the heads that warp unless you go HAM and run the thing forever with a blown gasket (not the case here, clearly, this one was probably shut off as soon as the coolant temp warning came on) but anywhere that hot gases have tracked over the block outside of the liners it might have scarred the surface a little, I'd have thought, as that isn't material that's designed to contain hot gases. At the very least, having the block professionally re-finished is 100% worth is on an engine that new with that kind of value.
Doing a lookup in brain, cold storage section, so take it for what it’s worth. At 23mins you mention X pattern cuts in the bore. If I remember right the x pattern is part of the bore cut and is to help evenly wear and seat the rings.
4 cylinders with a flat plane crank like this one have second order vibrations naturally, requiring 2 balance shafts if made to be smoother and higher revving.
It is true that 4 cylinders with a flat plane crank (which is like, 99.999999% of them except those weird Yamaha R1s) have second order vibrations, but often smaller displacement ones do not have them (balance shafts) as the size and weight of the pistons directly affect the magnitude of the vibrations and if balance shafts are necessary or not.
@@darylmorse Many do. My VW has a balance shaft less 1.5 I4, and the previous 1.4 also didn't have them. the Honda 1.5 doesn't have them. I don't believe the 2.0L in my old 2012 Focus had them either.
2litres was reckoned at one time to be a maximum limit for 4 cylinder engines without balance shafts, but for sports cars where the vibration was tolerable. Peugeot 1.9 litre Diesels didn't have them but only went to about 4500 rpm. Specifying "flat plane crank" really isn't necessary as nobody builds car engines any other way and Yamaha only do 90 degrees for marketing purposes - you can sell some bikers any old rubbish as something special.
Another commenter who works with these engines stated that the burnt through plastic water to oil cooler housing DOES melt and dumps the coolant in seconds...right where that hole was on the one Eric took off! Time for an aftermarket ali housing to be manufactured???
I can guarantee you the oil filter housing went out. Coolant leaked for a long time. That housing cracks and leaks as early as 60k miles. Left unchecked and not replaced with an aluminum variant or new plastic oem. Can quickly lead to air in the system and causing an overheat situation.
Imagine the time before power tools? Doing all this by hand with ring spanners must have been a chore, even socket sets must have been a god send when they came along.
One good thing about most modern German engines (for Eric) is they don't have dipstick tubes to fight. I have to say for 95k, this one is really clean inside so I'm guessing it got better than the usual BMW 10k change intervals.
I absolutely HATE having no engine oil dipstick on the B48 in my 2018 MINI Cooper S. 5k oil and filter changes for me, and a lot of the reasoning behind that is I can't actually look at the oil on the (non-existant) dipstick.
i have a 2018 330 with a b48, very cool to see the internals. i think its a generally pretty well built engine, due in part to input from toyota as you can get this engine in the supra. forged crank and connecting rods and arc/lds coated cylinders. there are folks pushing 500hp reliably with the some of the later gens.the cooling system can be problematic, specifically the line to the expansion tank which had a recall.
I think thats the case with this engine here on video they tunned Pressure got to high for gasses to leak. I have same engine and is solid. Only when engine is cold little rattling from waste gate, + i had to change coolant cup. I was loosing coolant and no leaks. Was the cup evaporating
I used to be a BMW fan, but after countless overheats and water pumps over so many years, I don't think they really care about reliability and longevity, and unfortunately that has extended to most German cars I have owned, the only huge exception being a VW TDI which got around 50 mpg and ran forever while needing very little attention other than regular maintenance. It was sold when it had nearly 300k miles just because a larger vehicle was needed. I would not go back to the other German brands, though. Their reputations greatly exceed their realities.
If you pay shop rates an old BMW can bankrupt you. If you do the work yourself a good well cared for example can be a hell of a lot of car for cheap. You can win big when a great car is out there almost scrapped just because of maintenance items nobody wants to pay for.
I have been driving a Porsche 968 for almost a decade and the only thing that went wrong were some old parts being worn, a common issue with its ring pinion gear in the gearbox, and some oil leaks caused by worn seals and gaskets. Basic maintenance is easy to do on it, and it's been problem free for most of the time I drive it. It never overheated and everything seems purpose-built for durability and performance.
Buy VW get a TDI. Change the oil every 10k at most and regular filters you will have an engine that goes on and on and on. At 50 mpg. You Yanks don't know what you are missing. Just don't do lots of short journeys with it.
Have got my young boys into watching your channel... So good for understanding Engine designs.. Great videos, love em all..Have u ever done a Nissan VQ37VHR . was wondering as I've only seen a 350z, not the 370z.
That VHR is in several Infiniti models from 2009 to 2017 ish... very surprising he's never done one. I'm waiting too, because the VQ35HR in my roadster has been done by Eric twice (!) and the VHR in my G37xS sedan (2013) just hit 200K on the odometer this past weekend.

Hot fire awaits engineers who put the timing system on the back of engines.
Instead of fixing their cooling systems they decided to over-engineer the timing system.
My 2006 Explorer has the best of both worlds - a crank-driven jack shaft and camshafts driven off the jack shaft with chains front AND rear.
This is what would make me the most nervous about buying any vehicle with these engines. Timing guides failed on these in the past. I can't imagine the cost of a full engine out repair.
Imagine what awaits those who put water pumps behind the timing chain system 🔥
All of the "technology" already exists. Cam in valve cover. Fuel pump in valve cover. Rear timing. Water pump behind timing cover. Wet timing belt. Boom, you're pulling the engine every 60k. Awwyeah. Ford will probably do it first, if their recent abominations are any indication.

Regular oil changes help reduce the risk of timimg related issues - I change oil every 10-12k km (6-8k miles)
do you know if they make aftermarket metal alternatives?
*effect, not affect. 😉
Back in the early 2000s when I was into e30s every used one I would get, I learned the first thing you did was replace the entire cooling system!
So true! My ‘02 330ci got the whole cooling system replaced every 60k miles.
Yes sir, and then most of the electrical system and then about every gasket on the engine. JUNK
That's my experience with E30s too. But then that's almost the case with old cars I've had. I've replaced radiators, water pumps, thermostat, cooling and heater core hoses on my 30 year old Celica too. However I can say the Toyota will run without issues despite having coolant leaks compared to the E30 325i I used to drive.
@@ricksays7133 God bless Toyota engineers.
Automotive Engineer for Honda here. Those BMW motors are pretty solid. Toyota uses them in the base Supra. The rod bearings looking like new at 100,000 miles kind of proves that. BMW makes some great engines. It's the emissions regulators and accounting teams that force us to use plastic cooling systems. It's not just BMW. If you don't replace the cooling system at 100,000 for any car past 2008, you're on borrowed time.
I agree that the metal machined parts of this B48 engine look rugged and extremely well made and machined. Lots of savings could be made by making things less well and still last well enough. But no, some dinglebunny accountant comes along, you claim, and tells the engineers "Ve must sev 5 cents by using a plastic water pump impeller". Right, that and three bucks will get me a cup of what passes for coffee these days. Makes no sense no matter how one looks at it. Emissions? A water pump impeller made of plastic that lasts forever in a dump, if not in the engine. A metal one is easily recyclable.
I look at that "oil cooler" and see O-rings tortured into crazy shapes on the block used as oil "seals". Suddenly, German rationality is ditched.
Look at Honda screwing the J35 with DI, using $3 injectors that fail at 50K miles, as South Main Auto has shown. Honda sells a cheapo six pack even at its dealers for this "wear" item. Plus who knows how much labor to replace them, when it's only a 30 minute job, according to happy mechanics reporting in at beating the book rate by a country mile. Hell, the timing belt lasts twice as long.
I've seen accountants at work, and they generally come round to reason, and blaming "emissions" for use of plastic parts is pure hogwash -- nothing, I mean NOTHING, to do with it. Discarded plastic in landfills lasts for ever,; scrap metal is easily recycled. You're not getting your excuses past me, I'm an engineer too.
I mean, even the most cost-cut engine I've seen here, the Hyundai 1.6 turbo, made out of spider webs and 1 mm thick alloy lasts 100K miles.
So these robust BMW engines have to have built-in failure points -- on purpose. Same with everyone else. Otherwise we have to assume engineers are all Jekyll and Hydes, which is absurd. Like running rubber toothed belts in oil at Ford and VW, and those useless DI injectors at Honda. Or VW using expensive special iron on their otherwise dog's breakfast of a 2.0 liter turbo four. That's the stupidest mechanical design I've seen torn down on this channel -- a complete nightmare.
Much as I hate to agree with Internet opiners, I see a conspiracy to produce junk. 95% good, and then crap that will obviously fail. Not the way my mechanical engineering career went, but it wasn't in automotive which seems like scam city.
Toyota/Lexus UR, GR series entered the chat. Not trying at argue with an engineer but this is to prove your point that some companies accounting teams are interested in using higher quality rubber hoses and not using plastic water pumps, like Toyota, Honda, Mazda and Subaru. Maybe even Mitsubishi although it is a dying breed.
@@Methylphenidate2803 Oh how naive you are. Toyota/Mazda/Subaru are all using the same cheap processes. It's called injection 3D molding. No company is using plastic water pumps as of 2009 either. What they tried is using plastic impellers for a while. "Higher quality rubber" is so painfully incorrect. All manufacturers such as BMW, Toyota, and whoever use the same quality rubber". Generally, quality companies like Continental will make the hoses. The big differentiator is that a performance car tends to run at higher temperatures naturally. Your average Toyota is tuned to underperform generally compared to something like a Camaro SS. Thus, it will make that rubber last a bit longer. Finally... You should really be replacing these "high quality rubber" parts every 8-10 years on any car. Not doing so means you aren't too knowledgeable on how a car works and are on borrowed time. Gaskets/hoses/etc. degrade with heat and lose mass. It wasn't until the last 5-7 years that new materials were compounded to better tackle this issue, but those are all aftermarket.
This is one of those moments where it's better to remain silent than to speak and assure someone you are not informed.
@@BillMalcolm-tn3kq You're not wrong. ALL companies are 100% taking shortcuts. I blame it on regulations and greed mainly. The US wants 70& of a car to be able to rot into the earth environmentally after its use. What does this mean? It means corn-based plastics and shortcuts just to be able to produce a car.
Ahhhh no
Dude! My wife loves to listen to you in the background and watches all you're tensioner and water pump shenanigans. Today she has suggested that you need a clear safety tote (she even gave it a Rev 3 designation!) for your convenience.
She actually has learned a ton about engines and to my surprise has even spoke about engine topics while we're driving down the freeway!
Keep up the great work!

Be careful. Last time I did that, my wife got knocked up! 😂😂
Are you going to burst through the screen? Bust a nut?
Give me my 2004 Lincoln Town Car 4.6L 2 Valve. Three or Four years ago I had the mandatory heater hose nipple break off on the interstate. I lost all coolant. I only noticed when power reduced as it went into the "Air Cooled" mode running on 4 cylinders and 4 pumping air. Got it off the road safely with reduced power. I had the intake and hoses replaced, refilled coolant and that is it. Total repair was $600 done by a professional mechanic. it is now 20 years old and 225,000 miles. No check engine lights. Drives and looks new, only the drivers seat gives its age away. Ill change that soon enough.
I like your balanced, factual, philosophical, non judgemental theories and conclusions when summarising the probable reason for the overall engine failure. I'd say manufacturers could learn a lot from your teardowns, it's often hard to predict what will fail when designing an engine and easy to apportion blame after the event. That said, the use of plastics, for whatever the reason, appear to be the weak link most of the time. At least this engine appears to be much improved, when compared to previous versions.

I saw a drift race engine builder use the side of the engine to mount it to the engine stand. Used an adapter plate like you would for the rear but setup to use the motor mount instead
Nevermind 🤣
That was a common practice with old, iron block BMWs. We used the oil filter mounting bolt holes.
I really want to thank you for your videos. It's very relaxing to watch your videos at the end of a hard day of work. Again, thank you so much. God bless you and your family
Love this channel, love Erics' humor, love seeing crappy engines being torn down.
It's a win all round, wouldn't you say?
His good deed for the day is completed, there's now one less intact 4 banger BMW engine in existence
One of my "go to's" when chillin in the office. Always the best .
I’ve had 5 BMWs from a 1996 535i and to the 2015 X5 with the 6 I’m driving today. I’ve only had one give me trouble on the road. A 2000 323i that gave up its alternator at 235,000 miles. I think it’s to be forgiven. It sounds like some of you guys have had bad experiences but I really haven’t.
I would love to see you tear down a 2.4 SRT4 that came in the 2003 Chrysler PT Cruiser GT with the aluminum intake. If you can get your hands on one. Great video as usual.
those had cylinder cracking issues if im not mistaken
An engine condemned for a blown head gasket. In my day (60's and 70s) that would have been $100 to $200 to R & R the heads plus $80 to rework the heads. (New valves and springs and milling the head level. The only way we would throw the engine away would be if the block itself was warped, extremely rare.
Rainman Ray had a Ford engine he wrote off as he said just replacing the gasket was 14 hours, never mind doing anything with the head....
Thanks Boomer
You are welcome.@@hijinks21
The problem is that these small displacement turbo engines have a very high specific power output so there is LOTS of pressure and heat involved. When a head gasket fails it’s usually pretty cataclysmic. I lifted a head on a late-model small turbo motor from preignition and it ended up spraying coolant right out of the side of the engine. The scary part was that once things returned to normal the bolts still had enough tension to allow the steel shim gasket to seal and it even passed a compression and leak-down test. But, the reduced bolt tension allowed trace amounts of coolant and exhaust to seep by, which eventually would end up trashing the engine due to coolant contamination and rust. If you catch it right away it’s fixable, but by the time it gets to this point, it’s cooked.
sure, they were ruggedly simple...and that's about it. Not necessarily powerful unless you had a swimming pool worth of displacement, drank through tanks like no ones business, and many still weren't even all that reliable. Many vehicles past the 90s, specially many Japanese ones, will gladly eat up miles upon miles. Hell, even my old BMW got beaten on daily and had over 160,000 miles on it. Engine purred like a kitten and pulled smoothly. This all comes at a cost. You can't just fix modern cars in your backyard like you could back in the day.
As always Eric, thanks for the Saturday night entertainment. Happy Memorial Day everyone, and thank you to those who paid the ultimate price for our freedom.
Amen.
Yes sir our service men & women are the best, we owe them for our freedoms
Thank you Eric Saturday would not be the same with out your video. I am long past holding a wrench but injoy the teardowns.
117th! Eric, how’s the engine that you were going to send to Ray in Florida for the van repair going? Roger in Pierre South Dakota
Sunday mornings with coffee and engine tear downs, so relaxing.
Who wife’s think they’re crazy too.😁
The X patterns on the cylinder walls is a crosshatch pattern to retain oil,very important!
They just keep making engines more complicated than they need to be, and having the timing system at the BACK of the engine, is a real a**hole move. Not to mention the over-use of plastic parts where they shouldn't be.
The Germans seem to like to do this and I hope the engineers that thought this was a good idea have nightmares for the rest of their natural lives
Even Caterpillar and Isuzu is doing it now on large L6 semi truck engines, not to mention using a belt drive oil pump in the engine. It's planned obsolescence.
Timing BELTS running in oil is probably the single worst trend in modern engines. Using plastic for parts that should be metal is just a tick behind. Failures from these two happen regardless of how well one maintains the vehicle. Sad.
Engines designed to eat themselves right out of warranty, so people have to buy a replacement. Makers just don't believe in quality anymore, only volume and profits.
@@billgraff4809 Well, the BMW M52 and any other Engine of that era used plastic chain guides and they rarely fail. The ones I pulled from a 2003 M57TU engine with 330k km were in pristine condition. A bit more on the brittle side than new ones, but after 20+ years of permanent heatcycles, i think thats okay. A friend of mine has currently 600k km on an unopened gasoline engines, still runs strong.
Plastic guides DO work, when the chain and guides are well engineered.
I’ve been anxiously waiting to see if you’d get one of these!! I have the B48 in my 330i
Great video !
thanks for another killer teardown sir
So there I was, pointing at the tv like Dicaprio while watching you carefully hand hold those guides instead of launching them across the shop floor.😂
My 2009 N51 is doing great at 146k. No turbos, no DI with HPFP, cooling system serviced and no leaks. Just a solid daily driver. Knock on wood.
The turbo heat cycles on that engine warped the engine block, it's common on all turbo applications where the turbo is directly mounted to the center of the exhaust manifold.
Amazing, sunday morning coffee, it was actually a boring teadown, but you made it entertaining anyway. This engine looks like it should have been rebuilt with a head job in the car.
Love your videos!
You are quite the business man. I'm glad you're doing well. Unlike that Hot Head BMW.
It's fine. It'll be fine....
Great Video!
Very interesting and visual display of a cooling system failure and subsequent damage. (why have weird cam gear bolts) Love your videos
another good video as usual.
Great video.
The old engines from the 70,s and the 80,s were so much easier to work on and longer lasting then to days
Because now German cars want to be the most technologically advanced cars on the road
4:05 - Stephan Papadakis did a whole build series on his B58-powered drift car quite a while back, and he welded up a bracket for side-mounting the engine on his stand. It seems like the only safe way to do it while retaining access to the timing chain components.
Really digging your videos, keep it real!
My neighbor bought a 2019 X3 with 60k miles and kept it for only 6 months because it already was having major problems. BMW made phenomenal cars in the 80’s and 90’s. They make unreliable status symbols now for people who think having a lot of debt and getting a loan on a some they can’t actually afford somehow equates to being wealthy.
They dont call them Bavarian Money Wasters for nothing
poor people buy new BMW's, rich people drive old Toyota's
The last good, solid BMW engines were designed by Paul Roche.
@@joskd8491 No they don't 😂
My 2018 B48 had NGK's from the factory. When I replaced them with plugs I bought from a BMW dealer, they were Champions from France. They might be replacements. IIRC the replacement interval is 60K miles on most B48's.
X pattern crosshatch from final machining of the bore.champion plugs suck,you all know it.
Another great episode, Eric, thanks so much !!! As an old fart (real old) I'm amazed at the complexity of today's modern engines. And to me, so much unneeded complexity, and all for what? Increased power, fuel economy, etc??? I'm just stuck in the past, I guess, and reminiscent of the multitude of American small block V8's (trouble-free) I owned and drove the bejesus out of, from shore to shore.
My n63 nightmare engine in my 550i just crossed 100k miles last week. Still runs as smooth as glass somehow. Imma see if i can get the n63 high score.
I love the new engine parts hardness tester! Also I think that the move to rear timing chains is for added revenue on the service side of the dealership to make up for slow sales maybe?
Compare to C&C equipment channel where apparently somebody dumped gravel into a dozer engine!!!
Real gravel
Love the euro engine stuff lately 👍🏽 what’s the chance of getting a V12?
x pattern is called honing. It's done in the factory so oil sticks to the cylinder wall better. If used motor still have it it's a good sign. It means it's not worn out and well maintained.
I don't know who BMWs material scientist is for gaskets, hoses and o-rings but he has been working for them for about 30 years now and he settled on the self disintegrating stuff in his first week and then put his feet up on the desk
We sell these quite well. The fwd engines are more expensive than the rwd versions. The problems i usually find are blown head gaskets and cracked pistons. If there is a loss of compression in one ir the cylinders then you have a crack in the piston between the rings.
Belting in the water pump had me LOL
Looking at the the build quality being much better than that Subaru engine you recently tore down is interesting. Unfortunate that BMW uses cheap plastic for their cooling system.
I was once told that European cars used “bio degradable” plastic engine parts vs “recyclable” plastic parts on other brands. Might be true: on my M54 Bimmer you WILL replace the coolant expansion tank every 60k. Or else…..
Meanwhile my ‘11 F150 Ecoboost went 160k on the original “de-gas bottle”, it being strong as day one when I traded it.
More BMW Love, nice video!!!
The oil filter housing being plastic was most certainly the cause of the failure. And for less than $100 you can get an upgraded all metal housing from multiple aftermarket sources to prevent this problem. And so could BMW for that matter. If they cared.
lot's of plastic on that motor - inexcusable for motor of that money - but that's what its come to
From all the crusties on the water pump and elsewhere it probably ran low on coolant which is what doomed it to failure. This is alluded to by Eric’s comment on the thing basically being the Sahara desert inside. While the metal housing will do a much better job of circulating the exhaust gasses that have taken the place of the coolant without melting, the outcome would have probably been the same.
@@hordesoflocustevery new engine is like this if not worse.
A lot of vehicles have that plastic oil filter housing..nothing wrong with it...just change it every 5k miles and don't overtorqure it
I would love to see you get some sport bike engines in like a yahama r1 or a zx10r
Ya know that water pump should be in a car seat.....jeeez, the nerve of some people!!

I have a couple of cousins that live in Germany that are BMW enthusiasts, when they have noting better to do they drive their BMW's but when getting somewhere counts they drive something else (an Audi for one and the other has a Mercedes) neither of them use their BMW's as daily drivers. They also have a slightly crude nickname for BMW in Germany that translates as "Bavarian Manure Wagon".
So why are they enthusiasts since they don't trust their engines?

Then they're kind of less of an enthuziasts. I myself drive my bmw as a daily. Averaging 3-4k km / month with my F10 530d xDrive. Fixing whatever needs to be fixed while I'm in garage or I'm in a pickle while being near parts store. One "Pickle" situation happened because of the plastic coolant tube that's attached to the head, 40€ and 3hrs on the side of the road and now it's running great, no coolant leaks.
@@luckgrip252 I own a e92 N55 BMW and drive it almost daily, cars are meant to be driven.
I guess you're german?
The problem I have is that here in Mexico there's no one that truly deeply specializes on BMW engines, so I have no one to directly ask for advice so I have to watch videos and forums, hoping there's nothing too complex that I cannot do myself.
Anyway how much do mechanics know about BMWs where do you live, mate?
The water pump always gets me 😂😂
thanks for sharing
I worked on a B48 a couple weeks ago at work, lady complained of coolant leakage. Discovered it was leaking from that topmost gasket on the oil filter/cooler housing. Also the GFRP on the housing had broken in the same place too.
Was on the chain removal part when washing machine need me.. And i saw waterpump wearing seatbelt when im comeback, hmm.. 🤔🤣
Painting the engine vs putting a tag on it:
I’m thinking that it’s because it’s easier for a nefarious character to take the tag off than to take the paint off
Have a 2018 BMW N20. It's been really good to me just an oil return line.
Get home from picking up cake, coffee and juice for tomorrow and get a video to watch, sweet
Good to see the condition of the internals on this B48, as I have one in my 2018 MINI Cooper S. Well, actually mine is a B46, but they should be the same, right? At 50k miles now, no issues whatsoever, and it doesn't seem to burn hardly any oil, maybe 1/2 quart of RedLine 5W30 Euro TD oil between my 5k oil/filter changes. I just switched over to Mobil 1 5W30, so we'll see if that continues. The B48 timing chain location definitely had me a bit frightened, as the timing components on my 2011 N18 MINI Cooper S were supposed to be rather weak, although mine seems to be fine at 127k miles now. I did have a head gasket failure on my N18 at like 88k miles, combustion gases into cooling system (much like the failure on this B48 you tore down), but that was on me due to not correctly bleeding the cooling system after a coolant change. I couldn't find a local place to resurface that head, so I bought a good used 38k mile head from a Euro auto salvage joint, all new BMW gaskets and such (no timing components except the upper chain guide and the TTY bolts that needed replacing on the cam gears etc.) and all has been good since then. Thanks, Eric, for the great tear-down videos! Keep them coming, man! Take care, and stay cool.
I have a BMW 328i with N20 engine. had it since 2014. Oil changes done every 5k miles. 55k total miles so far. No problems so far!
N20 timing chain issue fix after 2015 Jan
55k is like new
All these choices are great but what about a oldie but goodie Ford 4.6l 2V , never seen them on the channel.
You know, I think I would really like to see you tear down an old flat head. I have several and am about to learn how to work on an engine with them. Would be invaluable - especially to see you try to get a distribution tube out of a 50's dodge.
Eric does cars. BMW does the owner's wallet.
"I just broke my tool". Ouch, man!
I know someone with an n20 with around 100k, 12 years old out of an x1 automatic. The timing chain / guides was replaced under warranty before it had issues.
All luv bro❤❤❤❤❤❤
Love the Safety tote!
On the subject of "noooo don't tear the bottom end apart!" - I would be very keen to check and have a machine shop check and re-deck the block, which needs all the rotating assembly removing to do. The block likely isn't warped, it's usually the heads that warp unless you go HAM and run the thing forever with a blown gasket (not the case here, clearly, this one was probably shut off as soon as the coolant temp warning came on) but anywhere that hot gases have tracked over the block outside of the liners it might have scarred the surface a little, I'd have thought, as that isn't material that's designed to contain hot gases. At the very least, having the block professionally re-finished is 100% worth is on an engine that new with that kind of value.
Need a way to mount engines to the stand at the motor mount pads on the side of the block. Cummins guys do it. Seen it with b58 recently.
Anybody noticed the small writing on the safety tote? 😂😂😂😂😂

4 cylinders with a flat plane crank like this one have second order vibrations naturally, requiring 2 balance shafts if made to be smoother and higher revving.
It is true that 4 cylinders with a flat plane crank (which is like, 99.999999% of them except those weird Yamaha R1s) have second order vibrations, but often smaller displacement ones do not have them (balance shafts) as the size and weight of the pistons directly affect the magnitude of the vibrations and if balance shafts are necessary or not.
@@rudolphna54 A 2L I4 definitely needs balance shafts. I'd be surprised if any auto manufacturer makes an I4 without balance shafts.
@@darylmorse Many do. My VW has a balance shaft less 1.5 I4, and the previous 1.4 also didn't have them. the Honda 1.5 doesn't have them. I don't believe the 2.0L in my old 2012 Focus had them either.
@@darylmorse Be surprised, by far most I4's don't have balance shafts.
2litres was reckoned at one time to be a maximum limit for 4 cylinder engines without balance shafts, but for sports cars where the vibration was tolerable. Peugeot 1.9 litre Diesels didn't have them but only went to about 4500 rpm.
Specifying "flat plane crank" really isn't necessary as nobody builds car engines any other way and Yamaha only do 90 degrees for marketing purposes - you can sell some bikers any old rubbish as something special.
Thanks for the laughs bro E.... great presentation of a GASKET failure 😢
Another commenter who works with these engines stated that the burnt through plastic water to oil cooler housing DOES melt and dumps the coolant in seconds...right where that hole was on the one Eric took off!
Time for an aftermarket ali housing to be manufactured???
I can guarantee you the oil filter housing went out. Coolant leaked for a long time. That housing cracks and leaks as early as 60k miles. Left unchecked and not replaced with an aluminum variant or new plastic oem. Can quickly lead to air in the system and causing an overheat situation.
Imagine the time before power tools? Doing all this by hand with ring spanners must have been a chore, even socket sets must have been a god send when they came along.
One good thing about most modern German engines (for Eric) is they don't have dipstick tubes to fight.
I have to say for 95k, this one is really clean inside so I'm guessing it got better than the usual BMW 10k change intervals.
I absolutely HATE having no engine oil dipstick on the B48 in my 2018 MINI Cooper S. 5k oil and filter changes for me, and a lot of the reasoning behind that is I can't actually look at the oil on the (non-existant) dipstick.
You have to do a water pump museum or mausoleum, including rails on the timing chain
I think BMW is waiting for the cooling engineer to retire they hired in the 80's, any moment now.
i have a 2018 330 with a b48, very cool to see the internals. i think its a generally pretty well built engine, due in part to input from toyota as you can get this engine in the supra. forged crank and connecting rods and arc/lds coated cylinders. there are folks pushing 500hp reliably with the some of the later gens.the cooling system can be problematic, specifically the line to the expansion tank which had a recall.
I think thats the case with this engine here on video they tunned Pressure got to high for gasses to leak. I have same engine and is solid. Only when engine is cold little rattling from waste gate, + i had to change coolant cup. I was loosing coolant and no leaks. Was the cup evaporating
Problem is the coolant line recall was only limited to a couple of countries, even though it affects all B48's of a certain vintage
I used to be a BMW fan, but after countless overheats and water pumps over so many years, I don't think they really care about reliability and longevity, and unfortunately that has extended to most German cars I have owned, the only huge exception being a VW TDI which got around 50 mpg and ran forever while needing very little attention other than regular maintenance. It was sold when it had nearly 300k miles just because a larger vehicle was needed. I would not go back to the other German brands, though. Their reputations greatly exceed their realities.
If you pay shop rates an old BMW can bankrupt you. If you do the work yourself a good well cared for example can be a hell of a lot of car for cheap. You can win big when a great car is out there almost scrapped just because of maintenance items nobody wants to pay for.
I have been driving a Porsche 968 for almost a decade and the only thing that went wrong were some old parts being worn, a common issue with its ring pinion gear in the gearbox, and some oil leaks caused by worn seals and gaskets. Basic maintenance is easy to do on it, and it's been problem free for most of the time I drive it. It never overheated and everything seems purpose-built for durability and performance.
Buy VW get a TDI. Change the oil every 10k at most and regular filters you will have an engine that goes on and on and on. At 50 mpg. You Yanks don't know what you are missing.
Just don't do lots of short journeys with it.
This might be the a good way to mount engines now.
ive had 2 minis, a b38 and a b48, both had the oil cooler changed at around 62k km(38.5 k miles) otherwise all good with both of them
