- If this is the first teardown you are finding, there are over 20 others I've done! Lots of LS's, A viper engine, rx8 rotary, and a couple SRT8 Hemi's to name a few. Check them out here • Blown Up Engine Tear D...
My name is Eric and I own and run a full service auto salvage business called Importapart located in the Saint Louis MO area. Part of our model is dismantling and selling parts from rare and niche market engines. If you're interested in buying parts from this engine or others I've torn down, email us at Importapartsales@gmail.com.
In this video, I completely dismantle a BMW N63 4.4L Twin Turbo V8. This is BMW's first Turbo V8, and it is a Hot-Vee configuration where the turbochargers are in the valley of the engine. This engine can be found in BMW 650, 750. X5, X6 and some others. This particular engine is from a 2009-2013 F01 chassis 7 series. This was the longest teardown yet, but I still don't think its the most difficult to work on. That being said I am NOT a fan of these engines, regardless of how well they run.
I hope you enjoyed the teardown! As always, I love all the feedback, suggestions and criticism. Catch you on the next one!

Lol after 135k miles, I had to sell my beloved 2011 550i. I did the valve seals and all. When it works, the engine is absolutely fantastic and powerful. Responds to tunes greatly if done properly.
Once it breaks, run.
That’s the old version. It’s been completely revised now. None of those issues are around now
@@chriskarsseboom2200 What did they change between the 2011 and 2020+?
@@chriskarsseboom2200 theirs still issues
Anyone that owns a BMW that ends in -50i is a brave soul.
I do but it’s a new engine and turbos in mine s
Very brave soul that’s why I personally won’t work on BMW’s
@@andresquinonezramirez9373 I personally prefer wrenching on BMWs or anything Euro because of the customer base. Most BMW owners are aware of high repairs and are willing to spend money. The cars themselves may be tedious but not hard to work on. My customers that have Toyotas and domestics are the cheap, bring their own part that won’t fit type of customers.
😭 thanks for telling me after the damage has been done
I'm on my 3rd one. 750Li, X5M and M550. Love these motors.
I've become more emotionally invested into this teardown than all of the new shows on Hulu and Netflix..
Great tear down and video... as if I am right there with you doing it. No horrible music, over-dramatized dialog, just straight at it. Love it! Thank you
Still a better love story than Twilight.
Suggestion: Throw motion sensors on all the lights in your warehouse. They did this in my workplace and it had a less than one year payback including parts and electrician labor.
Everytime he cracks open another engine I am more impressed by the GM LS & LT. GM's design is so simple, elegant, compact, and powerful.
The last engine that someone can really work on fairly well as a shadetree mechanic. Some of the newer stuff your like oh hell no I'm not even going to try.
I’d have to say the same with hemis. Pushrods just are more simplistic and it’s a beautiful thing
@@CPO-kn5uo hemis arent exactly reliable though, they have a reputation for power but not reliability. anything chrysler/dodge/jeep/fiat is pretty trash these days
@@bradhaines3142 I wouldn’t agree with that but to each their own. Cheers
I work as a hobbyist on early 2000 bmw. And AMG Mercedes. I agree with you. Gm has it down from a engineering standpoint. Beautiful engines. This n63 is a piece of shit
Pro tip: For bolts with a shallow head, or with minimal damage, use a lathe and machine the leading edge of the socket opening so that the internal bevel is removed. This will greatly increase the contact area between the bolt and the socket, making it far less likely to strip the head of the bolt.. I have done this to many popular sized sockets for just this purpose. Hope this helps all who read this.
I have been a Mechanic for over 35 years. I specialize in GM, Toyota, and BMW, though I work on everything from small engines, to any automobile, on up to industrial machines.
Very common technique for suspension rebuilders too. Even an impact socket can be turned in the lathe with carbide tips, I prefer 6 point impact sockets, diamond file to bevel the inside faces just enough to take off the inevitable sharp edge, use the lathe to bevel the outer lip just enough to stop the lip being sharp
Great idea. Now I need to buy a lathe. 😆
@@mediocreman2you can use the side of a bench grinder or if your brave enough the side of a angle grinder
Just put the socket on extension into drill/driver/impact then belt sander/grinder. Awesome tip to remove tip.
Wow. Look at the size of your facility. I had no idea it was industrial scale. I really appreciate that you take the time to do these teardowns in amongst all the owner-ey stuff a place like that calls for.
The entire facility probably is what we can see. Here on the West coast the junkyards are at least that big, but out there theft might be a major problem, so it's enclosed. It's very impressive though.
I would quit my office job to work there.
No hi n B BCD’s
This is why Germans go bald so early. What have I created. Integrate the wiring harness into another harness. Big valve train controlled by weak chain guides.
7:42 makes me so thankful that I drive a rig with a carbureted 300cid I6 in it. There's more wiring on that BMW V8 than there is in the entirety of my truck!
Ford 4.9?
I remember swapping out chev 350s and helping my brother swap out his 340 out of his 1969 barracuda and we could do it in an hour. 1 wire to coil, coil to distributor, distributor to plugs, 1 big one to the starter, some smaller ones to the solenoid and am I missing anything?
Yup. It was the 300 before it went EFI they switched nomenclature at that time.
@@TestECull one of the best motors ever
@@frontspring1 Hahaha yeah I'm in no hurry to V8 swap my F150. I'll just build up the 300 instead. Love that engine. Prolly never see one on this channel though they're too long lived and too indestructible~
If we did see one on this channel it'd only be a 15 minute video. They're so simple that stripping it would...well Eric could just straight up post unedited real time footage and still not be overly long.
Wow. This engine makes my Audi 3.0T look as simple as a flathead 4. The open air oil catch pan in the valley is really forward thinking design. Keeps the oil from leaking all over the ground, thus improving environmental impact by BMW.
To do a lower timing case cover in a x5m pays like 48 hours, gotta pull down absolutely everything and take apart the engine to bare block, pretty fun job to do
Good lord. At least they never leak, right? 😂😂
And this is why they are all over copart with "engine damage" lol
@@trentdaddydolla647 huh, given that the reman long block from the bmw is only 3 grand with core, it sounds like they might be an interesting buy
@@fastboatster not really when they want over 20k for an 2015. Too much
@@trentdaddydolla647 yes, that’s too much. If they had something slightly older for a lot less then that would be good. But anyways, I recently saw a 2011 550i with misfire for 6k, and I think even if I’d have to get another long block, that would be a great deal for a German twin turbo v8 car. N63 seems no more complicated than 4.0 tfsi but costs a lot less
Q: "Why is your BMW in the shop all the time?"
A: "It's complicated."
Bc its a bmw > bring my wallet lol i work on them they are a junk design
noice one
@@robwells5753 to say its a junk design is a bit far fetched. on these ones, maybe. but otherwise the older gen motors like the I6's are rather simplistic and easy to work on.
“It’s plastic”
@@Zo_So96 true that i should have been more clear that its only the last 10yrs or so BMW went downhill with the overkill of plastic parts in engine bays shows a total lack of engineering. BMW's, some GM and Dodge products (Fords? i never been hungry enuf to work on one ) are my bread and butter.
One of the few CZcamsrs I'll watch start to finish no matter how long the video. Thanks for the entertainment
This and project farm are dependable to have great videos
it is something to watch .
Ditto !
I just did an engine out service on an N63 out of a 2011 550i, and we replaced timing chain and guides, valve stem/guide seals, and walnut blasted, along with the lower timing cover, oil return block, and every other gasket, including head gaskets. Total labor ended up being 64.1 hours.
How many miles on the clock?
@@vumba1331 127,000~
@@J-Kersting O/K, so reasonable use. Not too bad.
And for those poor people in the audience ......How much was this approximately?
@@vumba1331 that’s pretty trash for only 130k miles. Should not have to do all of that with that mileage
I’ve been looking forward to this video. My wife and I owned a 2012 750Li. I was on a road trip headed home and 80 miles away the engine started making an awful noise and I noticed the temp gauge climb to 250. The engine lost power. I got a tow home and took the car to BMW of Montgomery. They gave me the run around and wanted to charge me about $15,000 for a rebuilt motor. I kindly informed the service manager that I was aware of the class action lawsuit brought about by this trash motor. He didn’t look too surprised and brought the price down to $5000. It took a couple weeks but I was alerted to the completion of the install and was told the car was ready to go. We picked the car up and a week later got a low oil light. I took it back to troubleshoot and they said it was low and wanted to perform another round of consumption checks on the newly installed long block. When the car was ready to pick up, I got in to find the infotainment screen was black. I circled around the building and returned to the service department. I was given a loaner and they were going to look into why the screen was dead. I get a call a week later saying they suspect the screen is bad and it would be about $2000 to repair. I laughed and said it worked when I dropped it off and it better be working when I come to get it and I’m not paying squat. So a week goes by and I get a call saying BMW will not pay for the screen. I was PISSED. I called the owner of the dealership and explained the story. I was told it would be fixed at no cost to me… and it was. I picked the car up and went straight to a GMC dealer and bought my wife a Yukon Denali.
Never again will I ever buy, lease, drive, or even look in the direction where a BMW may happen to be located. The cars are 100% trash. At least Ford paid out billions in warranty repair on the 6.0L that was trash. BMW had to be taken to court and they still require you par for part of the motor and the full cost of the R&R cost. Stay away from BWM and stay even further away from BMW of Montgomery in Alabama.
that denali not gonna be fun to own once it gets old either lol
@@liblib89 yeah my Yukon Denali 2016 model bent a rod at 80mph on the highway and completely trashed the motor. 34k miles. The 6.2L GM motors are absolute trash.
How long ago did this happen to the car ?
You were the victim of the Steelership experience!
Let's go BMW!
Yup, I've replaced a bunch of stuff on mine including the oil return cover, oil return lines, a bunch of gaskets, coolant line, etc... most of the problematic areas to not have to worry about for awhile as I do plan on keeping the car for a while, but it teaches you a lot along the way. They are maintenance heavy vehicles but nothing drives like these engines so for me it is worth it...
I'm with you Eric I wouldn't own one of these. But it was still cool watching this one get torn down. Thanks for doing these cool tear down videos!
Love the tear downs man. I cannot picture ever working on an engine as complex as that one.
I can only imagine if you need to work on in when it's in the car! How labor hrs at how $$ an hour?
Slight gain in emmissions and economy makes the engine nearly impossible to maintain and therefore the entire car is disposable.
How is that supposed to be "green"?
It's supposed to be a status symbol. If you care about being green you get a 4-cylinder economy car.
That pretty much sums up the state of today's vehicles. No wonder the resale values crash after the warranty expires. They are so complex that they are too expensive to repair. So much for sustainability.
@@darylmorse Couldn't have said it better. also I don't need a status symbol I can't rely on.
ask corrupt eu politicians
They want and will kill the car as private property, thats all they want, if peasants cant afford to fix their intentionally over complicated and flawed trash new cars then its quite good in their eyes, less people will drive
Another excellent teardown video, Eric - it's always good when I can learn something, be entertained and you make money! Am particularly fascinated by the tech/assembly differences between Euro/Japan/US. Keep em coming please.....
Between the valve guide seals and the ridiculous oil change intervals most of these N63 V8s were not longed for this world. Very sad considering how amazing these engines perform when they work. Very well maintained ones that had customer satisfaction recall preformed are still out there running with high mileage. Should be good money for parts alone. Great video sir!
From now on when I see a turbo V8 BMW on the road, I'm going to laugh and say, "joke's on you, buddy!"
Dude, your attitude and comments make this channel...
My first car was a 1969 BMW 2002. I rebuilt its engine as a 19 year old and loved every minute of it! Cars were so much easier to work on then and just as much fun to drive if not more so! I would hate every minute of trying to keep up with maintenance on that monster! Just saying!! I Love watching you tear all those engines down though!! Great videos... Thanks!!
I always love your tear down videos. Nothing beats kicking back on a lazy Sunday watching someone else getting their hands dirty 👍
The term "over engineered" seems to play here. Engines are very simple. Regardless of turbo or supercharged. This is just a freaking mess.
I agree.
Some people buy cutting edge engines simply because they admire the technology, kinda like when people buy 10k mechanical watches with jewel bearings, even though a Casio keeps time just as well. BMW knows this, and they deliberately disregard maintenance cost because they don't want 15 year old BMWs driven by crackheads to drag down their image. It's the same with wasting money on Amsoil or Snap-On tools; it's an emotional purchase and part of peoples identity. The regulatory environment is also a big driver; to get this much HP and hit fuel economy requires a lot of technology.
@@taylorc2542 I agree. What happened to the day when you could buy a v8 engine and maintain it with a few simple hand tools. It shouldn't cost over a thousand dollars just to change spark plugs and wires.
It became possible to do all the V8 things using 6 or even 4 cylinders. Not much demand for a 'simple, reliable, inexpensive' spark ignition V8 outside of the US, where they are still popular in 'trucks.' Everywhere else such vehicles are usually running I4 or V6 diesels
That pretty much applies to all things with German automobiles. Over-engineered to failure.
Nice to see you get some sellable parts afterwards, dude. Thats almost as gratifying as the carnage!
I can honestly say that you're the only youtuber that id watcha 38 minute video. very informative and keeps me intrigued and wanting to learn more thank you bro😁
Definitely one of my favorite channels on CZcams! Keep up the great work! Fascinating to see the differences between the engine manufacturers. And I have learned from you to never buy a Mazda with the 2.3T....
This makes the 350 hp 327 look like a dream.
just finished the joy of dealing with a n62, 30 book hours just to check timing, brutal.
Wtf? Horrible, sorry Man.
That's not right, you mean 3 hours. These cars and engines are actually pretty easy to work on once youv'e done a couple
I've been researching the possible purchase of an Alpina B7, which has this engine. Thankfully, I've already learned about the first gen N63 and its issues, so my search is 2014+ models. Thanks for creating this video. I learned a lot!
thank u so much for this video, my dad and i have been trying to find a video showing how to take off the timing chain cover for the longest time, this was very helpful. and it was pretty easy to take apart but when its in the car itself it is a pain in the ass
Would you like an engine with your wiring harness? That wiring harness looked like a hot mess of a nightmare! I can only imagine troubleshooting electrical problems on that beast!
There appears to be like 200+ft of wiring harness alone on the engine. Absurd!
plug in the OBD meter and the computer talks to the obd with codes = but your no mechanical knowledge !
@@ronnieboucherthecrystalcraftsm If that fails, you unhook it and proceed to get the apprentice to break it down for scrap.
Haha, really!!
You don’t you just throw it away.
The valve seals were bad on my N62 V8. Smoked like hell and wouldn't pass smog until I used some BarsLeak Valve Seal treatment. No more smoking and passed smog first try after adding it to the oil. I just added it after every oil change and never had a problem again. #nosponsored
I feel so invested in these and so happy when you come out ahead.
The way you strip these engines is done like a true professional, good job
I had a 2012 N63 and it was constantly giving me headaches from coil packs to turbo oil leaks, battery, air springs…..the list goes on. Still, a very punchy and responsive power plant and wouldnt hesitate to buy a new one now that they’ve revised the engine :)
Long duration oil changes don’t help. A very smooth, powerful and efficient engine. Change oil 2 twice a year.
Make sure you use a real synthetic oil (Group 4/5) like Motul or Liqui-Moly. Almost all U.S syns are just Group 3.
How many miles do you have
@@audettere mine’s a 2020 with 15k mi. I knew about the valve guide seals going into it. From what I read BMW improved these seals, but because it’s a “hot vee” design I could understand the added stress. So I am not taking chances. My X5M50i is relatively fuel efficient (avg 19.7 mpg) which is mostly city, tows 7500 lbs (I tow an enclosed car trailer), ridiculously quick for a 5000lb SUV, and supremely comfortable. I intend to keep it for many years.
@@ProjectFairmont 19 mpg is kinda crap
@@dieselgeezer18 Not bad for a supremely comfortable vehicle with 523 horsepower and 553 lb-ft of torque. 3.9-second zero-to-60-mph , quarter-mile 12.4 seconds at 112 mph and weighs 5336 and can tow 7500 Ibs.
If I could ever even figure out how to dismantle the engine, I would never be able to put it back together. This just blows my mind.
I'm an aerospace maintenance & pilot guy, working mainly with turbine engines. Also a car guy (S2000). Always appreciate the quality of your videos. Really shows how simple turbines are Vs piston engines.
I work in aerospace maintenance too on the long haul tin. Glad gas turbine engines are properly designed and thought out, unlike this BMW shit-storm. Can't beat jet engines even though I love my Jaguar XFR beef and gravey 5.0l V8.
90% of the overcomplication on modern automotive engines is due to taking prehistoric technology (internal combustion engines) and trying to clean them up enough to meet emissions requirements. It’s a losing battle until they completely scrap the current ICE design and start over (or scrap ICE entirely)
Excellent tear down!
I've owned a 2011 (totaled by a drunk while parked last year) and currently drive a 2014 550 (10/2013) which has served me well. I would say I'm 4.1 out of 5 wrenches in skill level and In my opinion this engine is fantastic. It makes excellent power for it's MPG and routine maintenance is easy enough.
BUT: Most drivers do oil/fluid changes and brakes at their convince. Maybe sooner if they hear a noise. First stop being the dealer. I call this the Dealer cycle.
Heat will kill this engine. You must be fanatic with your coolant flushes and oil changes and don't forget to check your levels- You you can tell BMW went the extra mile to squeeze all the extra bit of cooling they could within the chassis. Dealer cycle maintenance and inspections will not prevent heat death- That's a hot warning.
There's little driving habit changes and parking tricks you can do to cool down your engine but most people don't want to do this and that is OK.
Because this engine requires vigilance and extra attention I caution the laid back BMW owners and new shoppers alike to steer away (pun) from this engine. Look into a N55 or if you want something fun an 05/06 M54.
Again, excellent video. I'm glad I found your channel!
Hey i bought a 2016 750i with 37k miles. Full warranty till 75k miles from carmax. Any idea how often i should do the coolant flush that you are talking about. Also oil changes every 4k-4500 miles ok? recomended oil? other than that just follow the manual for all other recommended maintenance? also what do you mean by driving habit changes and parking tricks . I live in las vegas so its hot AF during the summer...lucky we're coming into the cooler months. appreciate any tips you can offer
That is a great warranty. Make sure you hold them to it! And welcome to the HOT V party!
Regular intervals are fine. Unlike an alarm clock you cannot snooze on oil and coolant flushes so keep a log book or make calendar reminders in your phone.
Background: This engine has coolant for the engine and coolant for the turbos powered by an auxiliary pump which pulls from the small tank up front. Upon stopping the engine after a hot run you'll hear the engine fan running and what you cannot see is the aux coolant pump running to cool your turbos. This is normal. A BMW mechanic I know thought this was a fault but it is not.
My idea is simply help it cool down.
On your way home after city driving or hard driving: leave it in comfort ( no sport) for a while as you drive home. When home, park somewhere you can open your hood to let that hot air out for an hour or 2. No need to keep it open all night and dont open it if it's going to rain! Bonus: If you have a garage, get a box fan and hang it from the ceiling. Please be careful, be smart when working around your hot engine. Good luck, congratulates again.
Forgot.. oil. I live in Illinois and i run 10w40 which is thicker than the stock 5w30. Thicker is better in high temperatures I would consider a 10w40 in Sin City lol.
Good luck!
@@sharomoini6655 Thanks for the tips man. Much appreciated!
Hey Sharo, i own a 2010 X5 50i with 8k miles on it. No issues yet. What can i do do prevent those kind of problems with the N63 engine?????
Imagine trying to trace a wire on this engine.
I have subscribed because you seek what caused the failure, not just showing the results. Thanks for sharing your knowledge! Be safe!
I have a 13 F07 with the n63tu. I meticulously maintain it, and change the oil at half what bmws oil change interval is with Pentosin. I found myself dreaming about a teardown of my engine and comments about how clean the internals are and the lack of any wear on the bearings. Great channel.
A few years back I remember doing the valve stem seals on this type engine with the engine in place on the vehicle. It was an absolute nightmare.
The notorious N63. BMW lost a class action lawsuit due to this pile of junk.
the original version yes....not the updates
Did the S63 make the lawsuit also? Cuz mine is a driveway ornament
@@03mm24 Get a powertrain warranty, pay it for a couple of months and then file a claim.
@THE FBI So is making a $105k truck that conveniently breaks down a mile after warranty is up
@THE FBI How? He said his car is not being used I assume due to fear of not wanting to break anything. Get insurance for it if it breaks in a couple months file a claim. Didn't know I had to explain how insurance works lol
Your back! Good video. And please keep these tear downs coming!
Saw a 2010 GT 550i at the auto auction tonight. Good looking car 126k miles. It Was running with heavy white smoke. I just hadn’t ever seen a hatchback before. I was mesmerized. I just kinda sat and starred like what is it? I liked it. It hits the block and bottoms at 3K. I found my hand starting to twitch like an impulse was about to jump up and say hello. surely it can’t be that bad… and then suddenly I began to think of your channel.. the twitch in my hand stopped and the hatchback 🚗 rolled off into the night.. I wave the smoke from my face and start to get giddy thinking do I get to play pretend and virtually tear down a twin turbo V8 tonight?
Well sir. Yes I do…
just want you to know that this channel saves lives.
Thank you for what you do and
God Bless
Friends don’t let friends buy n63’s
Were all the engineers that designed this engine in different rooms at development?
Hahaha
Or maybe all together scheming the ultimate revenge.
different countries more like it
You probably think you wrote a joke, but it is not a joke. It is a common practice that engineers really sit in different countries.
@@razberik8320 No I knew that. And it's not a joke. It's ridiculous
Best to avoid this engine before the TU Update, ie: pre2014 model years. Most of the issues were fixed from then on.
And that goes for the S63 as well
They tried to do tweaks , if unlucky enough, you can still fall into the same line if problems just not as highly
@@48hourrecordsteam45 You're wrong, I own an N63TU and was a BMW technician at Pacific. upgraded. Keep up with maintenance and it's perfectly reliable.
The N63TU doesn't even share anything in common except the block and accessories. Everything from the pistons, Valvetronic heads and turbos are ugraded.
You are indeed wrong. The later Tu and above versions of the N63 share virtually nothing with the original, aside from displacement and a gasket or two. BMW would have been smart to rename the engine to avoid confusion. Owning an N63TU,TU2, or TU3 is pretty average as far as maintenance and repair.
@@jaybomb5022 considering to buy 2014 650i gc with 86k miles, water pump had to be replaced. Carfax looks pretty decent. Do you think it’s pretty risky buying it with this mileage? Originally wanted a 640i and stick with v6 for reliability but I know it really depends on the last owner and how well they did preventive care.
Man I would never see a engine like that in real life. You sent me on a trip thru the internet figuring out what a hot Vee was. What a wild set up. Thanks for the video. Again I would never see a engine like that.
You can use the main and rod shell bearings to protect the journals. Put a dab of grease on each, press on, and secure with a wire tie.
Good tip
Try doing valve seals on one of those with the engine still in the car.
Just an FYI… The Ford 6.7 L PowerStroke “Scorpion” turbo-diesel has a hot-V layout, too.
So is the duarmax
And most diesel v8/6 engines. It is cheaper to make them hot V because both manifolds can meet the one turbo, although I believe some of the duramax engines had the exhaust manifolds on the outside. The reason for it is it makes the cool charge air isn’t sitting in the hot valey inceasing efficiency
Awesome dismantling.. I love working on these engines... compare to any others... but your right you have to either have blinders for it to produce 440hp, but it always has misfires after 100k miles.
Purchased a 2013 550i xdrive earlier this year, cosmetically was it great shape. Didn't know enough about this version of the N63 before purchasing it. I've changed the plugs/coils, ccv breather hoses, serpentine belt, oil, aux turbo cooler pump, driver cv axle. Did all the work myself except the cv axle. Runs great right now, but after reading in much more detail about the repairs I'm considering get rid of it while its functional. Disappointed in all the bad reviews, since the power in this platform is so addictive.
I just kept thinking how trouble-prone putting something like that back together would be. Go in fixing one problem and come out with issues due to missing a key step or mistake during reassembly. Not to mention the chance that it may have issues off the assembly line. Even with intelligent manufacturing processes the shear number of parts means a higher chance of some defective part(s) out of the gate. Excellent content BTW
When it comes to these modern engines, all steps are key steps. There is no fault tolerance. If its not re-assembled 100% right, the engine wont start, or wont work right and throw an ECU error.
I never understood the hot-v design. It seems like a great way to concentrate all the heat-generating components into a very crowded area of the engine. Recipe for oil consumption and maybe even a fire if you ask me.
The point is to reduce turbo lag due to the short exhaust manifold.
@@tedeby5351 Not worth the sacrifice just to reduce some lag
If you know how to take Care of an engine it isnt a problem
@@tedeby5351 And run a better dual scroll set-up across the heads
Eliminates any lag.
We are in for a big change when Battery Electric Vehicles become the norm - the sheer complexity of modern ICE engines and transmissions when compared to BEV Electric motors is staggering.
Good luck when your fancy proprietary control board gets fucked and you can only buy a replacement from the dealership.
Thanks for this video. As a F12 owner, I intend to buy a second engine, and rebuild it forged. It's nice to know it's a factory closed deck block so I can just have it sleeved. Video is highly useful for my purposes, thanks
These uploads are the highlight of my Sundays.
Only BMW could design an engine that weighs more in copper wire, then the actual engine itself.
Audi...hold my beer.
Truth
I used to work on these engines at the dealership. Such a pain in the ass! But not too bad after you've had your hands on a few of them.
Your methodical disassembly technique is so satisfying.
the wiring monster on that looked decently intact, I bet it would be a valuable part.
Standard German design philosophy: "Why use one simple part when you could use six overly complicated parts?"
When I wrench on my German cars I routinely have a mental picture of a bunch of German engineers at a conference table talking about the puzzles and challenges they will build in for us :-). But you do get an intuition for it over time…
And ford is doing the same

These vids are the best thing to look forward to on a Sunday
As always another excellent video.
Informative and humorous.
Just reinforces the earned BMW reputation of just why non simplicity of design and use of non temperature tolerating plastic guides.
Where do engine design committee's fail to keep and preform excellence standards,
Some parts are superb in design and others have no excuse for pure cheapness.
I did the valve seals on a N62 once and that was the last time..
how many cables you want on your engine?
bmw: yes
I tried to work on one of these in my mothers 09 X6 and it was a nightmare!!!! I've worked on a buddies LB7 duramax changing injectors and that was a breeze compared to the N63. I do like the power output it has but the cost for maintenance and reliability is what throws in the towel for me. I'll probably tackle a 6.0 powerstroke before I touch an N63 again, and I'll probably enjoy wrenching on it too!
I don't think I understand why watching you tear down engines is so fascinating, but, it is!!
Very cool to see this monstrosity come apart. It's ridiculous how overly complicated this engine is.
Germans smh
you should see the motor used in a Mercedes AMG63,
you can see why people love them for the first 50,000km and hate them for the next 150,000
Most overly complicated German engines like this have some type of fatal flaw or they have a massive coolant or oil leak from a $5 gasket that takes $10k in labor to install.
@@tjw8t1 - German engineering at its best!
You gon learn today son!
Very informative I appreciate these videos and you taking the time to make them.
I saw a lot of neat new innovations. Probably engineer tested but the real Beta test is always in the consumers hands. They WILL find any weakness. Not surprised about the oil pump - good place. Since central valley cams and distributors that provided a handy low speed hook up for oil pump drives disappeared, crank shafts are all that is left. This engines oil pump and front design shows they were trying to shorten the engine any way they could.
25:44 oh man. Someone needs an Astro tools sponsorship.
The physical size of that engine compared to its displacement is kind of incredible.
DOHC and that hot V don't help that's for sure.
I find watching these engine teardowns relaxing.
Id enjoy seeing a shop tour
Fascinating!!! This engine's "Hot Feed" system reminds me of certain Detroit Diesel Engine manufacturing company videos on CZcams. When I found these 40+ year old Detroit Diesel engines with what seemed to be hot feed, I was flabbergasted.
Hot V or vee because it's in the middle of the V of the engine.
Beautiful engine.
I think that the best engineered solutions are the simplest. All hail the Chevy small block.
here here!
Your running commentary is botheducstionsl ad entertaining. Great work.
Dude thanks for taking time to to make this video.
This is great video for reference 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
German engineering at it's finest. ..
More like German complication at it's finest.
They make great driving cars, but the drive trains are junk. brought to you by the Socialist Republic of Germany.
@@mikea5205 Ford Explorer V6 Engines were german. They put timing chains in the back. Guess what you have to do to repair it :lol: The guides are probably the same plastic as this Engine :lol:
@@alb12345672 The previous pushrod 4.0 V6 from Cologne lasted entirely too long, so they "fixed" it! What a POS the SOHC turned out to be.
@@bigpjohnson Yes, I have one in a 96 Explorer, it is pretty indestructible. It also has crazy low end torque. It lacks the HP of the SOHC though. With the 4.10 gears and low range it is great for crawling. The SOHC Is more powerful but pretty much all of them need overhaul. I've heard of some lasting, but it probably needs OCD level maintenance.
Its too bad about the mechanical issues of these engines because the power output and especially the delivery is incredible.
Actually they did a pretty good job with the CCP program. That initially replaced everything from seals, injectors and both Turbos. Had my 750 done 4 years ago. BMW had the car for a week and knock on wood it has been relatively trouble free since. The Turbo oil return lines still leak a little but then again my Silverado 5.3 marks its territory as well. What i wont complain about is performance. The 4.4 hot V will propel my 4000 lb car down the road as fast as a new Corvette. 0 to 60 in 4.6 seconds and speed limited at 165 MPH. it is a dream to drive at a steady 100 MPH. quiet, tight with great seating and audio system. But change the oil every 5000 miles, that's the key to keeping everything tip top.
I owned a 13 750i for a couple years,it was a beautiful, fast car. I'm glad it got totaled out before had to do any major engine work on it though.
I wanna see you tear down a Northstar V8 one day
Those are pretty simple engines.
@CZcams needs a Snickers imagine how pissed i was when i had to replace the starter on my Nissan titan after talking trash about the Northstar.. Same damn place!
I replaced the head bolts with studs and it’s been a great running engine. It’s a very smooth V8. Once you have done it you can get to the starter in 5 minutes lol
@@93sundance they aren’t bad with it out of the car. Inside the car (fwd ones) good luck working on anything
Yes
im not much of a “car guy” but i love watching these disassembly vids ive seen so many and learned so much! thanks! im curious tho why on earth would they use plastic as a material inside the engine. It seems that between the exposure to oil and constant heating and cooling it would absolutely fail. yes ? no??
plastic is a general term. There are a ton of engineered plastics., even bearing grade with mollysulfide to be self lubricating. In this case im not totally sure, not something you can spot outside phenolics. But id assume a german knows his material specs. I mean i use there carbide.
Be careful there is a real difference between a diyer and a certified tech!
Usually these parts are made from engineering plastics like polyamide. Phenolics are also possible. This kind of material is highly durable under those conditions and has proven itself in the past 30 years. This kind of failure we are seeing here looks like the pressure from the chain on the plastic was too high. If it is a common occurence then I might think the calculation was too optimistic.
@@itsannrg These plastics(PA, PEEK) also degrade from oil/additives and temperature at a rate nobody can predict. Even bearing manufacturers admit it. If anyone buys cars with chains in the engine, they should be let known that their engines are can fail if they don't replace these parts early enough. But it certainly wouldn't be the best sales argument at the showroom would it.
I work in vacuum molding plastic. And honestly, the pre-molded sheets would laugh at impact, laugh at 230°f heat and given a few layers be even more resistant..
33:51 - 125 Ferrari V12s (1500cc) did the same for the same reason. Pretty sure when they increased the bore to175cc/cylinder (2.1L), they squared them up.
35:52 - The mains are 'reverse-radiused'; saw that last on 255 Offys.
36:10 - The oil passages are bell-mouthed (upper left).
I can tell that you're a good mechanic A dying breed
I cannot wait to watch as more and more of these German engines roll in with turbos in the valley of the V and see what has happened to them with years + miles!
The "hot vee" style engine has the benefit of reduced turbo lag. Even the 6.7 Powerstroke uses this design, with a single turbo. As for the rest of the engine, looks like a complete mess.
Yup, Ford's PowerStroke has had the turbo in the valley since 2011, and that seems to be going pretty well. Plenty of those out there towing heavy with hundreds of thousands of miles.
Audi is doing very well with it. Been about 10 years now. But BMW couldn't make a good V8 to save their lives.
the only way to own one of these is when still under warranty !!!
really enjoy watching your channel man keep the videos coming.
I really enjoyed this tear down. I have a friend who has a MB G-Wagon that also had a “hot V” engine. It makes a lot more sense than say, Ford’s turbo diesels with the turbo on top of the intake,,and hot plumbing from the sides of the engine. But, Ford engineers are certainly a lot smarter than I am.
The point of my comment here is the revelations you made about BMW. It’s certainly acknowledged that BMW is a top quality, luxury brand. Yet you let a few “secrets” out about BMWs. They always leak oil! Wow, how surprising to a mere Ford ST owner. The complex BMW designs probably delight the design engineers, and do the same for the car’s proud and wealthy owners.
I really enjoy all your tear down videos. Cheers!
Love watching these disassembly videos. Any possibility of you doing VW/Audi engines in the future? Would love to hear you tear down a W8. 🤣
Humble Mechanic did one, two vr4 put together, over complicated for something like 220hp….. they sound wicked though.
@@PatricioGarcia1973 I know Charles did, but he's used to VW and their wacky engineering. I want to hear it from someone who makes a living off of LSs. 👀
I'm literally wearing that same shirt right now...
Bruh! I literally just got another yesterday myself, Ashville Super😀
Fashionista!
I don't have any pants on.
That was very fascinating, thanks for doing it 👍
Good video Eric im new to your channel , you look like you have a big workshop and also busy...nice to recycle parts that so many just throw away these days
