BMW HOT-V N63 V8 Engine Destruction! Internal Disaster! 4.4L Twin Turbo V8 Meets A Timely End.

To peruse our inventory and shop our parts, please visit www.Importapart.com or email us at [e-mail].
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!

[@Checryan]

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.

[@robertwest3093]

You must be quite the fan of this channel to ruin your own engine so we could be entertained. 😂

[@I_Do_Cars]

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!

[@Cartier_specialist]

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.

[@matspatpc]

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... :)

You are right about the pan being dropped so we could turn the crank far enough to get the torque converters bolts out.

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.

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.

[@briandonaldson9657]

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.

[@bobski3333]

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.

[@briandonaldson9657]

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.

[@bobski3333]

@@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.

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!

[@phillipmcintosh6489]

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.

[@Markomyt1]

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....

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

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! 😃

[@MASI_forging]

Great work dude. 👍👍

[@springguntunes]

Thank you Ryan.

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

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.

[@srt8madman727]

That was awesome. I'm pretty sure that was one of the top 3 destroyed engines that I've seen on this channel.

[@germanbosnia]

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.

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.

[@brendans1156]

I’d love to see a Porsche flat 6 at some point!

[@FixingWithFriends]

Are you _trying_ to jynx his car? haha

[@brendans1156]

@@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

[@narcisrivera7227]

Thanks for the video

[@Ratdweller]

That subtle n54 slander on the injectors;) keep up the great work love the vids

[@bobmeyer7009]

If I ever saw a nightmare engine, this is it. And that was before it blew up.

[@Hatemyself-xq7wt]

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.

[@Syncopia]

Here's the n63 owner

[@StreuB1]

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.

[@gmboy559]

Simply spectacular. Certainly in your Top 3.

[@BigHartAtack]

Engine tear down vid with Billy Madison references! I award you no points and may God have Mercy on your soul...

[@nickolaswilliams935]

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.

[@russellbrown1138]

this has got have been the best failure without actually exploding that I have ever seen you take apart. Keep up the great work and the fun disssembly

[@kevinsocha7853]

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.

[@UberUdder09]

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")

[@cadensunsdahl4837]

sir can you please do another 4.6 3V ik you’ve done one but I BEG OF YOU JUST ONE MORE

[@Backroad_Junkie]

Why does it seem that every german engine he's taken apart, has been majorly over-engineered?

[@dirtfarmer7472]

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.

[@JackPaarthurnax]

Best video yet!

[@nemethzsigmond4548]

Love it! Timing cover hid a real swiss knife with springs in it. This is actually an invention. Imagine a swiss knife which you pull out of the case, and everything just pops out. No more broken nails, you just put back what you don't need.

[@chuckz28]

Former BMW owner here. Tesla gained me as a customer because of this type of mess and I'm a mechanic. Never again 😂
