Anyone that owns a BMW that ends in -50i is a brave soul.

Q: "Why is your BMW in the shop all the time?" A: "It's complicated."

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.

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.

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.

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

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!

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.

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.

One of the few KZfaqrs I'll watch start to finish no matter how long the video. Thanks for the entertainment

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

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.

Dude, your attitude and comments make this channel...

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.

Nice to see you get some sellable parts afterwards, dude. Thats almost as gratifying as the carnage!

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!"

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!

This makes the 350 hp 327 look like a dream.

I feel so invested in these and so happy when you come out ahead.

I always love your tear down videos. Nothing beats kicking back on a lazy Sunday watching someone else getting their hands dirty 👍

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!

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.

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.....

Were all the engineers that designed this engine in different rooms at development?

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"?

Imagine trying to trace a wire on this engine.

Your back! Good video. And please keep these tear downs coming!

I find watching these engine teardowns relaxing. Id enjoy seeing a shop tour

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.

Love the tear downs man. I cannot picture ever working on an engine as complex as that one.

The way you strip these engines is done like a true professional, good job

Your methodical disassembly technique is so satisfying.

Definitely one of my favorite channels on KZfaq! 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....

just finished the joy of dealing with a n62, 30 book hours just to check timing, brutal.

These vids are the best thing to look forward to on a Sunday

I can tell that you're a good mechanic A dying breed

Long duration oil changes don’t help. A very smooth, powerful and efficient engine. Change oil 2 twice a year.

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.

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

Dude thanks for taking time to to make this video. This is great video for reference 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

Try doing valve seals on one of those with the engine still in the car.

Only BMW could design an engine that weighs more in copper wire, then the actual engine itself.

Very informative I appreciate these videos and you taking the time to make them.

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.

These uploads are the highlight of my Sundays.

Beautiful engine.

really enjoy watching your channel man keep the videos coming.

Glad to hear that you are able to do well with your motor store.

I wanna see you tear down a Northstar V8 one day

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 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😁

I have subscribed because you seek what caused the failure, not just showing the results. Thanks for sharing your knowledge! Be safe!

You gon learn today son!

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 :)

Your running commentary is botheducstionsl ad entertaining. Great work.

That was very fascinating, thanks for doing it 👍

I did the valve seals on a N62 once and that was the last time..

25:44 oh man. Someone needs an Astro tools sponsorship.

Great video and channel, very enjoyable to watch.

Your assortment of hardware must be epic. Great vids.

Best to avoid this engine before the TU Update, ie: pre2014 model years. Most of the issues were fixed from then on.

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!

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.

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!

how many cables you want on your engine? bmw: yes

the wiring monster on that looked decently intact, I bet it would be a valuable part.

New subscriber and viewer to your videos. Thanks for posting, I really like them!!

Love your video….keep a good work

Very cool to see this monstrosity come apart. It's ridiculous how overly complicated this engine is.

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

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.

I don't think I understand why watching you tear down engines is so fascinating, but, it is!!

I think that the best engineered solutions are the simplest. All hail the Chevy small block.

The physical size of that engine compared to its displacement is kind of incredible.

Great video. Will check some parts out.

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!

Everyone: If it ain’t broke- Germany: Fix it until it is!!

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.

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.

Thank you i have the same engine mines run really good but it nice to visually see it good job

The term "over engineered" seems to play here. Engines are very simple. Regardless of turbo or supercharged. This is just a freaking mess.

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!

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...

Love this channel. Learning a lot!

German engineering at it's finest. ..

Its too bad about the mechanical issues of these engines because the power output and especially the delivery is incredible.

I'd love to see a BMW N54 3.0 I6 TT teardown! Love the style of your vids!

You know what I'd love to see? A teardown of a hybrid! 😊

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. 🤣

I'm literally wearing that same shirt right now...

This engine is very different then the engines i know. Thank you for the video on a BMW engine.

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

Love when a new one of these comes out

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??

Beautiful disassembly of a prestigious boat anchor

Very cool to get a look see inside!

Standard German design philosophy: "Why use one simple part when you could use six overly complicated parts?"

That whole thing looks like a giant Rube Goldberg machine.

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 bought a X5 with an N63 engine so I really appreciate this video
