To see if I've torn down a particular engine, check out my other teardowns here: • Blown Up Engine Tear D...
WELL FOLKS! This is probably the longest teardown I've done as far as time required in the last several months. 8 hours of filming over 2 nights, 8+ hours of editing, 221 raw clips has resulted in what I hope ends up being an enjoyable video for you all. I don't ask for likes or subscribers because that's not my style, I try to earn both of those organically.
If you ask me what one of may least favorite engines is, this is on the short list. BMW's N63 hot V 4.4L Twin turbo V8. This engine, while an engineering marvel, is probably the worst engine BMW has ever made. They cost a small fortune to keep right and have RELENTLESS fault codes, expensive components, and many problems are never truly fixed. I'd say the overall life expectancy is 80-100k miles with average care. Pretty dismal. I could NEVER recommend anyone purchase an early N63 powered bmw, 2008-2013 are the non TU, or technical update, and are plagued with the most issues.
This particular N63 is from a 2011 750Li with 127k miles comes courtesy of Ryan at Smitty's Automotive in Hyrum, UT. For most cars, you'd consider that low for being 12 years old. This engine had multiple problems, the last of them resulted one a catastrophic failure which wrecked nearly half the engines worth of parts or more.
Why on earth am I doing these teardowns? I own and run a full service auto salvage business in the Saint Louis area called Importapart. Part of our model is buying blown, core and unwanted engines and dismantling them to resell the good, usable parts. We do not rebuild engines, we merely supply parts to those who do.
I really hope you enjoyed this teardown. As always, I love all of the comments, feedback, and even the criticism. Catch you on the next one!
-Eric
Hey Eric, I thoroughly enjoyed watching you tear apart this engine. Thank you for that. That was so much worse than I thought it would be, and I even had the oil pan off of that. As you correctly guessed, the loose rod bearings inside the pan was me. The engine was locked tight when I initially started removal. So off came the oil pan and after removing the rod cap from that one cylinder, I was able to get it to turn enough to get all of my torque converter bolts out. I didn't feel like it was worth my trouble to put the bearings back in place so I just threw them in with the rest of carnage. I didn't get into this engine any deeper than that, but my impression with what I saw matches what you found. This didn't appear to be a lubrication failure. That surprised me. In my experience most of the time you eject parts outside the block. a lubrication failure is your root cause. At least in stock engines. I second your assessment that it either jumped time and hit valves, or burnt a piston down from a lean cylinder. For those that care to know, I bought this car with the blown up engine off of the local classifieds. I was told by the seller that the car didn't run and that the mechanic he had taken it to said something about a crack and oil and cooling mixing and leaking, and it needed a new engine. That is all the information I have as to what happened to it. The car was in really good condition though, so I don't think that it was really neglected. I've been a professional auto technician for 20 years now and in my experience, people that take care of the body and interior of their cars, typically maintain them mechanically as well. I know there are exceptions to this, but that has been my experience over the years. If the body and interior are rough, likely maintenance has been shoddy as well. If the body and interior have been kept clean and nice, they've probably been good about their maintenance as well.
You must be quite the fan of this channel to ruin your own engine so we could be entertained. 😂
I agree, the best maintained cars look and feel the part. Bmw from this era has kinda figured out how to make their interiors and paint quite robust (excluding that soft touch crap), so I’ve seen lots of “clean” but neglected cars but you can still tell. Hope you did alright on this one. Really appreciate the engine, and if you ever need any parts, I owe ya one!
There's definitely exceptions. Some people only care that they look good when they're driving their car regardless of what kind of maintenance they skip or extend. I hear guys debating what the best motor oil is and what the answer to that question is obvious to me. The oil that's changed frequently regardless of the brand is the best.
I'm one of those people that don't care what the car looks like on the outside or in the passenger compartment, but I will make sure it's good on oil & filter, gets new airfilter, new plugs, etc according to manufacturer's recommendation. And the right kind of oil and filter too - not just "whatever is cheapest at the local supermarket". The outside of my car gets cleaned when it rains... :)
@@robertwest3093 - He didn't ruin it, he bought it already ruined. Didn't you read his whole comment?
Helped tear that out of the car, and can tell you the oil pan came like that. Oh the fun we found inside! You are right about the pan being dropped so we could turn the crank far enough to get the torque converters bolts out. When we were done, we put the pan back up with all the goodies we found in it so we wouldn't ruin your fun.
The real MVP.
What even happened to cause this lol
Solid effort, dude.
Thank You for not spoiling his fun and also making this video possible.
Incredible carnage you found, imagine showing that to the customer!
Too much boom in the combustion room. Mutilation in the combustion station. Castration of the piston-to-crank relation. Devastation of the bottom-end foundation. Debacle in the combustion tabernacle. Manifestation of engine block ventilation. Celebration of compression liberation.
Permanent cylinder deactivation. Cylinder disintegration situation. Compression no more.
Compression delete

Doom in the Room of Boom.
Me: "Hey Eric, you have any books on automatic transmissions?" Eric: "Nope, just manuals."
The dad in me will gleefully remember this one
@@I_Do_Cars manual elitest jerks 🤝
The design team on this engine were all on acid when they did this. This is what makes mechanics retire. Great video!!!
Mr. Rube Goldberg entered the chat, and swore he has never done any illicit drug....
The Saxons are still on pervitin and eukadol. They think it was perfect.jah!
No. Nothing like that. Just some good ol' crack...
Lmao 😂
The post-update variant (TU and onward) is a masterful bit of drivetrain tech. The early N63s were an absolute nightmare. They're all frightfully complex, but not terrible to work on. The worst part is all the plastic stuff (wire connectors, clips, brackets, PCV/CCV hoses and valves, coolant tees) they used around the turbos. Best thing you can do for longevity is throw a PTP Turbo Blanket over the factory turbocharger heat shield.
I absolutely lost it at "knock sensor working overtime" and still got treated to an extra 45 minutes of greatness.
Look for a knock sensor w clutch to help brake remaining rods when loss of crank weight is triggered...
Wow, the level of complexity of that engine is stupefying!! I can't even imagine trying to do routine maintenance on that beast at home, let alone actually repairing/swapping out parts under the hood! Thanks, Eric, for the great autopsy, as always, and thanks for convincing me to stick to older, simpler, more reliable vehicles!!
BMW has a solution to that, you just wait for the engine to blow and then replace the whole thing. 😅
I don't think you could honestly. Not without mega disassembly. It's almost like they were trying to stop you from repairing. My god!
@@Stylemaster911 I think so, too! They're making SURE you have to bring it to a dealership for even the most basic maintenance at the low, LOW shop rate of $249/hour!
Car Ninja has a shop doing repairs on German cars, mainly BMW. He also has a YT channel.
@@czarekaj1098 yes if I still had a European car (only had one, never again) I would take it to an independent specialist like Johnny once it was was out of warranty.
You need a longer slide hammer for those injectors, so you can get a bit of the long stroke action. Tends to work a bit better than short strokes.
That's what she said!
A longer shaft indeed
short strokes so as not to wake the master
If the short rod won't remove the injector, it can't be trusted if removed by any other means...
@@anthonybrod5559 It's good you picked up on the joke. lol
I absolutely love these tear down videos, Eric. You present things so well and I always learn so much. Thanks for all your hard work! We do appreciate it!
Been binge watching Adept Ape working on diesels since you did that Cat. Thanks Eric, even your channel recommendations are good.
Same here - the Adept Ape is a great find.
Same. Great channel!
I agree, I started watching Adept Ape as well, and then KT3406E. I did not fully realize that there is a whole world of very heavy construction equipment with accordingly large engines out there. Adept Ape and KT3406E have opened my eyres to that.
@@robertcochran7103 Big fan of KT3406E though he's getting out of truck engines. Diesel techs get paid ok as well. Food for thought
You know it's bad when you have to use a breaker bar and an air impact to pull a spark plug.
Hey. At least there were no drills involved.
I am but a simple man. I like me pushrod V8s. Simple as. But...I very much enjoy living vicariously through your channel and seeing what else is out there. Watching your teardowns is a staple of my weekend. Cheers.
I never owned anything BUT a pushrod V8 for 30 years, but finally had to relent when options became scarce if you wanted to drive a car-not-truck. Ended up with a GM 3.6 VVT and you know what? It's been great! I'm not buying this "increased interval" oil change BS tho. If anything it seems MORE important to keep the oil as clean as possible with the VVT engines and their timing chains?
This was a magnificent example of fine Bavarian engine carnage. I am deeply impressed.
Adds new meaning to Big Money Wasters ….
They sell you an 'experience'!
@@Syncopia albeit leaving a bad taste in one’s mouth
that entire slide hammer section was very hilarious to watch loving the teardown so far, keep it up Eric the best teardowns on the site :)
he definitely got some good practice in
When removing the head bolts, main bolts, and rod cap bolts, I think it would be interesting to see the "Breakaway" torque value just to see how tight they really were. A wonderful teardown as usual. I cant wait for next week, or the possible "mid week" teardown.
Between you and the other mechanics I have watched on KZhead, I have learned a lot about taking things apart. I was dropped a bad transmission out of my 260Z today. As the oil drained out, I did remark about the forbidden glitter mixed in the oil.
Those are the sparkles from the combustion fairies :'D
Thanks for the video. It's much more fun to sit and watch you work than it is for me to do it. I think BMW engineers must be competing with each other trying to make every part of the engine more complicated. Having the exhaust between the cylinder banks reminds me of the flat head V8 Cadillac. Which was prone to catch fire from rats nests.
That last spark plug sounded like a head bolt with that breaker bar!! Definitely a first for me hearing.
I’m a DIYer, and SO glad I own Hondas. I can’t imagine being a novice and trying to work on something like this, especially while it’s still in the car!
You said it. Even if I had a ton of money I'd stick with Hondas and Toyotas. I work as a caregiver and don't make a lot of money. My car is my life. No car no job. I watch these to learn more and to remind myself to ALWAYS maintain my car. This stuff is fascinating but yikes! This was bad. That must have made one hell of a sound.
To be fair being a DIYer with an E46 or similar isn't too difficult at all.
@@bradcomis1066I spent a year with a 2011 f10 550i. After the engine went to shit I bought back the 2005 325ci I sold. The e46 is so simple, I do not miss the n63 at all.
@@Ashw1115 That power from the N63 is pretty awesome though. I test drove a couple E60 550i's and they were awesome! Too big to fit in my garage though. Went for an E90. The N52 is a bit of pain in the butt to work with (so much computer BS). The M series stuff is a DIY sweet spot for sure.
Did anyone else notice the sorcery in the oil pump? Brilliant! It's a variable displacement oil pump. Unlike the 50's on American V8's with a spring and plug that dumps excess oil, as the pressure builds, that spring in the right side lets the rotor's housing move up decreasing the vane's displacement. So rather than heat the oil by spraying it past a spring loaded pressure relief it pumps less, saving fuel and not making extra heat.
That last plug was not a spark plug anymore. It was a spark rivet.
There we go. Now, I’m happy. Love Saturday night. Every time I watch these videos it reminds me of the engines I tore down when I started with my first cars….a triumph tr4a and a 65 Malibu 327 SS with 202 heads, Muncie 4soeed, bucket seats and a console. Loved those cars. Wish I still had them. I learned so much about how engines work by taking them apart and putting them back together when I was 16-18, that I still do most of my own work at age 65. Keep it up, please.
Another amazing teardown. I cracked up when near the end of the video, KZhead cut away to - wait for it - A BMW COMMERCIAL! That was just too appropriate. Still chuckling.
😂😂😂
I Love the fact that you explain what probably destroyed the engine....Can learn a Lot about the value of good maintenance!
Yea!! If you ever stop making these videos you are going to ruin my Saturday night! 😁👍
That was epic destruction! The N63 is definitely not one of BMW's finer moments, at least the earlier ones. I actually thought the engine wasn't terribly maintained, based on the varnish not being bad for so many miles, the very good condition of most of the bearings, including the camshaft bearings, as well as how clean the water passage for the water pump was. As the engine came apart, I was thinking it was killed by a timing problem in the passenger bank. I don't recall seeing you tear down an S55. Please find one!
I know this was a longer video than normal, but i really enjoyed it. I don't think it could have been made any shorter. Great job, and wow was that engine trashed! Last but not least, thanks Ryan!
I like to think Eric has a bin of perfectly fine wrist pins from all the motors he's torn down.
I salute you for your efforts to educate and entertain. This is hands down the most broken non-nitrous related disaster I’ve ever seen. The troops salute you. o7 o7 o7
He has a Honda and a Kia from just a few weeks/ months back that beg to differ. Here's the Kia, kzhead.info/sun/oNOwmc-JZ5yioqs/bejne.html Here's the Honda, kzhead.info/sun/na-mfrJ6g5h8n5E/bejne.html Have fun watching.
A Dodge Ram V10 begs to differ.
Yeah, Nitrous can cause all kinds of fun destruction, lol.
The ultimate teardown would include video of the engine's demise! If, somehow, you could do that it would be sooooo awesome! Imagine, a high revving engine blowing up and then you tearing it down. I wouldn't mind if you actually staged it... just so we could see the resulting carnage.
I thought that Eric was having a joke at our expense, but under all the pipes and hoses and wires there was actually an engine in there! great video for engine malfunction!
Re: the oil pump design, it looks like a variable displacement pump. The inner housing (that the rotor ring spins in) pivots depending on oil pressure (the shaft poking out of the pump cover is the pivot, and the big spring left in the housing counteracts oil pressure. As the housing pivots up due to oil pressure, the rotor becomes less eccentric - the big end of the inlet side gets smaller, and the small end of the outlet side gets bigger. That means it pumps less volume per revolution. If there's plenty of oil pressure, the pump backs off so it isn't wasting power trying to cram more oil into the system. If oil pressure is lower than ideal, the spring pushes the housing back down to a higher displacement position to bring the pressure back up. It depends on a spring, so it won't be just one way or the other - all the displacement settings in between are valid - it's analog. Since the pump can adapt, they can also use a much larger pump than usual which can maintain good pressure at idle speeds without getting crazy (both oil pressure and parasitic drag) at high RPM.
I caught that, and stopped to marvel. Should have read a little further down before adding the same comment. I don't know if chevy did this, but ford and dodge both have a high pressure bypass relief. (50's to 90's) Dodge with it's small blocks go a little overboard with this, so a 250K mile engine has the same oil pressure at hot idle as at 4000 RMP.
@@briandonaldson9657 AFAIK, a bypass valve is the standard minimalist approach - just dump the excess oil back into the pan. It wouldn't surprise me if BMW's pump also includes one to handle malfunction of the displacement-adjustment mechanism. Trouble is, as soon as that valve cracks open, you're wasting power. The the flow rate of oil being returned * the oil pressure at the relief valve = some value of wasted HP and fuel to make that HP. Yeah, I know... There may be no tangible benefit (or at least diminishing returns) from letting the oil pressure go higher. Still, dumping the excess has zero benefit outside of limiting oil pressure.
@@bobski3333
This is more like an engine autopsy than a teardown!
Glad to see all that practice you had since you were a teen has really paid off when you needed to get them injectors out. Anyway, love your videos. Keep up the good work.
Thanks for your advice on steering clear of these engines Eric. Greatly appreciate you sharing your experience, it saves me the potential pain and suffering. Cheers and keep up the good work.
Thank you Ryan and Eric! Great tear down as always
I have a feeling the driver of this car had his foot all the way down to the floor and more. A lot more. The sound of the explosion must have been deafening within a half mile radius. Well done!
Get a longer shaft for the slide hammer. Would make the job so much easier.
Gotta love it when Eric throws parts
Great show! Thank you Ryan.
Another fantastic video, as always Eric. Your tear down videos are the highlight of my Saturday nights as I wash endless mountains of baby bottles and pump parts. Oh the joys of fatherhood…
I watch all of your videos and they are awesome! Having owned 2 different BMW’s with N63’s, I totally enjoyed this. One of my N63 blew up with 60k miles and another was “bought back” by BMW. I believe there have been several class action law suits on these engines. Tell you what, I would never ever ever go near another BMW again in my life. Their engineering is horrible. They are all marketing hype and nothing more. Garbage cars after 2009 IMO
Best one yet! I can’t tell you how much I enjoy watching your videos. Good stuff! Please, keep it up!
This was certainly an interesting and entertaining tear down and thanks Ryan!
Said it before - I genuinely feel sorry for the techs that have to work on these motors.
That’s why the labor book time on these is so high
Same for audis with the TT V6 and V8. Both have their turbos sitting up top. Doing a good number of things on them suck. Powerhouses though.
especially in a car if its that bad on a stand imagine it in a car
It just requires a certain mindset and no distractions. I’ve done a couple of chains by pulling the complete front clip and just leaving the turbos the hell alone. Valve stems in car, a head in car by using an engine lift etc or at the complete opposite end there are guys who will just drop the whole driveline on a table for any repair at all.
Just another day with a B.M.W Blown Motor Works 😂
It's blown and it has also blown.
Break My Wallet
Bavarian MalWorks.
Love the longer vids!!! Usually more carnage. Please keep em coming
That wrist pin is the reason why I'm liking the video.
One thing I like about this engine is the fact that the alternator is at the top of the engine in the V, kind of like a Ford. You see, on the Porsche 928 (hint....) they put it on the drivers side low where it is exposed to road debris and water. The cooling duct always gets knocked off, and that of course causes fits with the air conditioning system, since it uses cooling air going to the alternator to determine outside air temperature....
Another example of shitty German engineering....
Some of the Germans have a water cooled alternator.
When you had your face at the camera reminding people not to buy one in my head I instantly thought of Adam Sandler in billy Madison when he grabbed the kid and told him don’t rush to grow up lol
Viewers coming in clutch for the rest of us. Thanks to Eric and the fans of the channel that donate teardowns. This was one for the record books, you can say that.
Wow. Just... wow... I don't think I've ever seen anything quite as devastated as that engine. You get the trophy!
Complex, beyond practicality.
Fragged BMW engines are the best part of this channel. 7 months working on these at a dealership ruined the brand for me ad infinitum. Seeing destroyed BMW tech gives me life.
Hey man! Just a quick heads up, when you use that injector removal tool, flip the slide the other way. It should be hollow on the other side to allow for further travel.
An hour of entertainment and a bowl of popcorn! Enjoyed this one a lot.
*vigorous strokes back and forth * "It's coming " *proceeds to stroke* "Yeah"
And it came 4 times in a row 🤣
I lost it at the reach-around
With all those n63 cores you might be able to make 1 and a half good engines
Even if you could build one working engine, it would still be an N63. It is therefore impossible to make any *good* engines from all those cores.
I really enjoy the tear down videos. I especially like the carnage of such engines.
Well, as Phil Swift (Mr. Flex Seal) would say, "That's a lot of damage!". Your weekly Saturday night videos never disappoint!
Like I always say, you need to be more of an electrician than a mechanic nowadays.💯
An electrician and a plumber. Lol
I had a '95 M3. I have never own another BMW because of my experience with that car. I enjoy all of your videos. Thanks for all your hard work
Ok drama queen... That's a pretty simple BMW. Those are easier to work on than today's Honda Accords. This N63 is just one of BMWs bad moments.
Loved my ‘97 M3. And that I thought was a well designed motor.
@@geoffreyoltmans4356When treated right, the S52 engine is more than reliable
Eric, as a retired.master mechanic, and having worked on everything from lawn mowers to rug boats, I can say, I agree entirely on this engine being one of the ones I'd stay a way from. Good video. And if you were not so overwhelmed, I'd bring you one still sitting on my engine stand from my sons Oldsmobile. Keep up the good work, makes us appreciate the good-ol-days!
When you think about it, the "hot V' design makes so much more sense..the intake comes in from the cooler outsides of the V and the exhaust comes out the higher inside of the V, where the engine is hottest anyway! Oh as far as the steel rod "trick"..that's BMW's new feature, the "pass-thru!" Adds extra cooling! But seriously, with the way I've seen the way some people hammer on BMWs, I'm surprised there aren't a lot more grenaded engines.
Yep I have n63t3 in a 2020m550i. Turbos are much larger. Close to no turbo lag with this set up.
That timing sprocket reminds me of a problem Mercedes had with the same thing, they hadn't been heat treated and were just smearing. I would guess that's the source of your failure. For a heat treated gear to lose all it's teeth, especially from a chain is unlikely. Those teeth are soft, you can tell by the extensive wear on the intact gear.
Wrong place to cost cuts in manufacturing.
While I watched you try to get the spark plugs and fuel injectors out, my first thought was that you missed your calling as a gynecologist.
Hey Eric, love the tear downs. Currently i have a vehicle with a Chevy 2.0T and am thinking about doing some upgrades internally. I am hoping that you can get a hold of one so i can get a rough idea on how to take it apart. I know it wont be identical and thats not what you do but i can still learn from it. My car is a 16 but it is in 13-19 Caddies, 13-22 Malibus, 14-23 Buicks, 16-23 Camaros, and 18-20 Equinox, Traverse, and Terrain
I always love watching these videos. Live confidently and peacefully
Good tear down Eric. When you found the fifth valve in the valley between the cylinders I thought that’s awesome it was trying to make itself into a flat head. The connecting rod thought if I beat this valve hard enough it’ll go up here and then I only need to grow a camshaft thus reversing evolution. I really enjoy your tear downs and your car collecting addiction one of my favourite channels.
Thank you Ryan! Hey Eric, I believe German Engineers are just like so many engineers... They over think EVERYTHING, and have to make it so complicated that even the trained service people working on their designs go "WHAT THE F**K?"! I think they give each other points for how many times the service people write to them asking that question! The same type of engineers are the ones that design traffic construction here in the U.S.! Anyway, thanks for the great video! Please keep up the good work! 😃
Another great tear down! Sometimes I would really like to see or hear exactly what happened when an engine is destroyed like that. This one must have been awesome when it was tearing itself apart like that. Thanks for having this cool channel.
I bet it was awesome! And.. my heart would drop if I experienced this on my own car.. oof! ("guessing it was more than a misfire")
That was awesome. I'm pretty sure that was one of the top 3 destroyed engines that I've seen on this channel.
Those things are a nightmare to work on. I agreed to change the plugs on one without knowing what I was getting into. What a piece of shit!! A million ducts and coolant hoses to disconnect and then a special socket to get the plug out. Who thinks to put a bend in the access hole to the plug in the head??? Idiots!
The ultimate leasing machine.... Really, it is to the point with modern BMW's that many shops simply will not work on them anymore. A shop fixes something, the owner drives away, and a week later some other problem crops up. "What the hell did you do to my car!" the owner screams into the phone from the side of the road. BMW has made their cars so complex while not emphasizing quality that really, you should never buy one. Lease one instead, they are awesome to drive! BMW like many other companies knows that few people work on their cars anymore. Thus, they design them to be cheap to produce and serviceability is an afterthought. What's more, due to our wealthy society, when a car does need an expensive repair at the 100,000+ mile point, most owners these days simply trade it in. I call it the "Airbus effect". Airbus has publicly stated that irregardless of hours and cycles, their airframes should be recycled at the 25 year point. Their point is that as technology moves forward, older designs need to be removed so that more efficient designs can take over. And while there is actually some logic in this, it is horribly wasteful. BMW seems to think that as well; 100,000 miles or 10 years, and the car should be removed from the road. And they design their vehicles to that standard apparently. Great video!
Airbus trade on the dispatch or mission availability of their products. BMW do not. BMW trade on driving experience and that’s it . When you are sitting in (or on in the case of a motorcycle) one of their products you can’t see how much of an entitled twat you look like. I’ve owned my share, they all broke down eventually
Hey Eric another great teardown as usual! I know these probably aren't too common but I would love to see one of those Nissan VC engines torn down would love to see how that works. THANKS as always for the Saturday night entertainment!
That subtle n54 slander on the injectors;) keep up the great work love the vids
I’d love to see a Porsche flat 6 at some point!
Are you _trying_ to jynx his car? haha
@@FixingWithFriends 😂 no, I didn’t even think about that. I’ve got a 987 and I’d love to see how they’re laid out
I was driving my 2012 750Li and the motor blew so bad that the piston came out the block and blew open my front diff lol the repair bill was damn near 30k thank god for warranty. Now she drives like a 100k dollar car Edit mileage was like 136k
At 57:23 you can see the woodruff key for the timing gear had exerted tremendous pressure onto the crank. You can see the stress fractures in the crank that it caused.
Epic damage! Another great teardown Eric, thanks for the amusement. Laughed at the lack of teeth on the timing gear
If I ever saw a nightmare engine, this is it. And that was before it blew up.
Me and my friends, Bud, Miller, and I do cars on a Saturday night. The lady's at her mother's house this weekend. It's boy's night tonight, baby.
Love all the videos you put out! As a truck guy, I like mostly the American engines but its always enlightening to see the Euro and Japanese stuff. My V10 Ram thanks you for the thermostat housing!!!😁
Epic destruction! Wonder if it would be possible to cut that block into a section to retain the trapped valve and engine improvised inspection ports as a rogues gallery show piece? Very spectacular show piece!
If you notice these have hollow valves, because they’re sodium cooled. While not common, the hollow valves can break leading to all the other carnage you found.
Engine tear down vid with Billy Madison references! I award you no points and may God have Mercy on your soul...
There was a lot of stuff in this engine I don't like from both longevity and maintenance perspectives however one thing I found very interesting is the adjustable stroke vane oil pump. The pivot's on the left and the plunger on right either decreases or increases in length which changes the amount of offset of the 2 circles thereby changing the oil supply quantity to suit the differing requirements throughout the rpm range. This way you can have your target oil pressure from idle through to max rpm. Normal gear style oil pump have up until now been a very cheap solution but they waste a lot of energy, and sizing (flow rate) is a compromise at best. Great video by the way Eric.
I saw the time on this video, what do ya know it was over just like that. Lots of things to see on this one. Time flies when you're in to a good video. Nice to see the pinned post too. A good read.
I have a 2011 550i (stick shift) with this engine in it and it's got 156k miles on it and it's still running strong. I just change the oil once every 4k miles and you're good. And it pulls like a jet engine. I had those plastic hoses upgraded to metal ones but that's it. That's the only work I've ever had done on it.
Here's the n63 owner
sir can you please do another 4.6 3V ik you’ve done one but I BEG OF YOU JUST ONE MORE
Eric, my stomach is hurting from LOL so much from this video and your ad lib humorous comments. I cannot imagine the noise that the engine made when the cycle of carnage started. Thank you for ICE destruction teardown entertainment to the Nth degree.
Really awesome video Thanks Champ
Why does it seem that every german engine he's taken apart, has been majorly over-engineered?
It seems as though they’re goal is to make it as complicated as possible & then a little more. They used to be very nice long running quality cars, now you couldn’t pay me to own 1, just junk.
Recently went through all my car subs and decided to let some go. Somehow this one has survived. Again.. Love your humour as well as your technical skill (although I can never forgive you for not doing a full restore on that e21 from my childhood..) Thankyou for all the great content and greeting from Oz 🇦🇺🏳️🌈
Great video, well done. 👍
Thank you Ryan.
Former BMW owner here. Tesla gained me as a customer because of this type of mess and I'm a mechanic. Never again 😂
Good evening Eric. You outdid yourself today. BMW (Blown Motor Works)is true today. The bottom end versus the top end of the engine destruction is priceless one of a kind.
Great work dude. 👍👍
