Every week I post at least one new engine teardown video. Here are some of my favorites:
BMW N63 Total Destruction • BMW HOT-V N63 V8 Engin...
Mercedes M276 Turbo V6 • Driver RUINED This 30K...
Nissan VC-Turbo 3 Cylinder • Nissan VC-TURBO BAD AL...
VW EA888 2.0 Turbo Major Damage • Volkswagen 2.0L TSI EA...
Today's engine is a 560 Horsepower Hot-V Twin Turbo V8 from a 2014 BMW M5 with just 102k miles. The S63Tu is the second iteration of M-car hot-v v8 and there are a lot of improvements over the first generation, but that doesn't mean they're perfect. Squeezing 560hp from just 4.4L is a feat in itself and it comes at a cost. In this case, the engine locked up after a wide-open throttle pull getting on the highway. What causes this type of failure? Could it have been avoided? Was there pre-existing damage and the strain of a hard highway pull just pushed it over the edge? What do you think? Let me know in the comments!
Why do I do this? My name is Eric and I own and run a full service auto recycling business called Importapart. Part of our model incudes buying blown up, core, or bad engines and dismantling them. We salvage the good parts and recycle the rest! We do not repair or rebuild engines, 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!

[@CorbinGoodwin]

This is my old engine! When it locked up it was basically like doing a reverse clutch drop at 7000RPM. To answer your question about noise, yes the tubular crossover manifolds sound weird. Distinctly V8 but not what I’d call a cool or beautiful noise. I had done plugs about a thousand miles before this incident hence why they looked so clean. The car was actually quite new to me at only maybe 1500 miles of ownership after buying it on BaT, it seemed very well cared for and from Texas. The car was stock as far as I could tell, and I wasn’t even doing a highway pull, it was 2nd gear and when I went to go to third gear the engine’t. So sad to see how nice the motor was inside aside from that bizarro failure, this whole ordeal has really soured me on the F10 which is a shame because it’s a marvelous car in a few ways. For anyone wondering the DMF was completely shot and close to being two pieces. I have an SMF on there now with a few other refreshed and upgraded components and it really makes the manual feel the way it was supposed to. Oh, and Eric it was an honor to have you tear this sad chicken apart! I’m happy it worked out this way, a silver lining on the BMW cloud.

[@davidg3944]

Thanks for the inside scoop, Corbin.

[@ferrumignis]

A DMF on a gas V8 seems overkill, since they have some of the lowest torsional vibration of any common engine configuration. One of those times I wouldn't hesitate to go for a SMF conversion.

There is a machine shop local to me that I take all the BMW cranks I come across like that to him. He can easily machine the crankshafts to better than new condition and balances the whole assembly for me. The most expensive crankshaft he's done for me was $480 out of an S85. He also did an S63 crankshaft for me that was just like that. Turned out brilliant.

[@muddywater6856]

Yeah....if a long block is 38k, that much and more would be easily justified.

It's now 10 years old... 3x it's warranty design life and 2x it's mileage "life". it is also apparently now known that rod and main bearings are 50k PM replacement. Speed costs...how fast do you want to go?

[@budlanctot3060]

Since it's a main bearing, this crank could easily be chucked up in just about any lathe and the bearing shell machined off until the shell fell off, or turned down to a couple thousandths bigger diameter than the journal, then ground very close to finish diameter. If concerned about heat treatment, a heat treating company could easily restore to hardness. I don't see a major problem fixing this crank.

[@succulentslug]

Holy shit, I saw this engine and had a heart attack. I was test driving an m6 with this engine for a noise concern, turns out the noise was rod knock that only could only really be heard under load.

[@AcuraLvR82]

Hey Eric, heres an idea. When you pull the crank and set it up on the bench, you should tap it with a wrench and listen to the ring it makes. Forged cranks will make a very distinct high pitch chime. Something I learned working on Hondas.

[@robertmaag3897]

True test but not necessary. Look at the finish on counterweights. Shiny with a machined finish. Cast cranks have a dull, grayish finish. One more thing: hold any crank up by one end (may need a helper) and tap the other end as you stated. Steel/forged cranks ring like a bell while cast ones sound flat.

[@Conservator.]

That would be cool to watch! 👍

I have to give BMW credit, they’ve really improved their carbon issues. Not just the valves, but those two piece oil control rings. VW/Audi phased two piece rings out in 2014 but some engines had them until 2018. Engines that still have them start burning a ton of oil by around the 70k mile mark and those rings are plugged solid.

Change the oil before it gums up and you're fine. They even solved the whole DI valve buildup issue by running the valves hot af. It doesn't totally prevent buildup but I think in normal conditions it's no longer a maintenance concern for the life of the engine.

[@TestECull]

@@hwirtwirt4500 It's pretty easy to see a direct link between longevity and how substantially built something is, how stressed it is. The more stress you put on a part the more wear that part is going to receive. and the more substantially built those parts are the more resistant to that wear they will be. You ask 560hp out of a 4.4 liter V8 you're gonna be asking a hell of a lot more out of the tiny little bearings in it than if you ask 140hp out of a 4.1l inline six. On top of that, higher redlines ALSO increase stress on components. I'm not entirely sure what the redline of this V8is but I am 100% confident it is significantly higher than the redline of my C10's straight six haha. Prolly 6,000-6,500 if I was to guess, against my 4100. Which is why we see this engine on Eric's teardown stand in effectively a crib death scenario with no bearings left in it while the 250cid I6 in my 1971 Chevy C10 still has perfect oil pressure 53 years later. My I6 is asking a hell of a lot less out of a much more substantial build, so wear is pissant negligible even factoring in the shitty oils it had to contend with for most of its life. T'ain't no different than tire life. The more aggressively you drive the shorter your tires live.

[@Akiss]

Regarding why the bearing failed, the theory for S65s is that the timing chain is tensioner too tight from the factory, so the bearing cap closest to the timing chain is pulled up into the top cap, causing it to fail before the other rod bearings. So the rod bearings all fail in a matter of time, but starting with the closest.

THIS….. just makes me love the simplicity of my 2URGSE……. ISF…

[@ouch1011]

I am so glad I don’t work on cars anymore. For fun, I looked to see the labor time to replace valve cover gaskets on this engine in a 2014 M5… 19.5 hours! That would be enough time to remove, fully rebuild, and reinstall an engine in something like a mid-2000s Camry. At a BMW dealer, that would probably be between $4000-5000 _just for the labor charge_ depending on where you are at what the labor rate is. Maybe more, I’m not really sure what the labor rate is at an M-certified BMW dealer (other than that it is outrageous). These make a 6.4 Powersmoke/Powerbroke look like a gen 1 SBC.

[@mobius-1503]

Same. Im still a wrench in the garage on personal/collegues vehicles and get to call what il do vs don't but maaan. The amount of junk under the hood on modern fords/ chryslers esp the turbo'd varients...gives me a headache just looking at it.

[@Bankrollprimo]

Oh, this is going to be good. The M5 is and has always been my dream car, especially the manual transmission versions.

[@wafflesnfalafel1]

Thanks for the vid sir. I was actually sitting behind a bit newer pretty black M5 at a light today and when it took off, and not aggressively, the thing blew so much smoke out the pipes it obscured my view... Are all those beat on? No oil changes? Design issues? All three?

[@svenscholten7995]

Next time you remove the timinggears from the camshafts, lock them with a spanner. That way you prevent them from spinning on the impact and make valve contact on tdc pistons.

[@notyou6950]

X7M came with that motor if im not mistaken. When I worked at the plant that made them this that was the most expensive vehicle they assembled. It came with 3 day driving school which was mandatory before you picked your car at the factory. The race track is on the other side of Hwy 101. That vehicle was bad ass!

[@sandorpardijr8439]

It is such a great engine. My M5 makes 610 rwhp and 647 wtq. So much fun too daily. Mine is at 135k but spun a rod bearing at around 71k miles and was rebuilt by Pure Performance in Houston. So ridiculously fast and comfortable. It does sound a little odd though due to the exhaust manifolds crossing over the way they do.

[@ronnymb67]

So main bearings should be part of a 40K service 😂

[@aland7236]

Well the rod bearings were maintenance items on the previous V10s so this tracks.

[@peto22]

@@aland7236 In all S engines, the bearings have a short life. 10w60 oil, tight tolerances and people's understanding of the properties of those oils when cold.

[@markcoveryourassets]

Must be why the auto lease lady I know says to lease em for no more than four years 50k with full service plan included. Too bad they don't make bearings you can pour in with a bottle every 40k.

[@robertfaulkner7152]

It also makes you wonder if BMW still recommends oil changes every 15,000 MI. Maybe that's why the bearing went to sh*t. My maintenance intervals recommended by BMW on my 645Ci was every 15,000 mi but I changed it every 7000 mi. My independent mechanic even recommended it at 8000 mi ( 1k per cylinder )

[@ronnymb67]

@@robertfaulkner7152 Extended service intervals came to exist with the Germans - Mercedes, Audi, and BMW - in the late 90s. Not because oils are so much better but because they wanted to move more vehicles. Without anybody getting offended, the reality was the majority of people who purchased those vehicles could afford them and afford to maintain them. What scared people away from owning them was what they cost to maintain. So they gave us "lifetime" transmission fluids(ask me how many 120,000 mile failed transmissions I've seen) and long oil change/spark plug replacement intervals, etc. "JUST MAKE YOUR LEASE PAYMENT! YOU DON'T HAVE TO WORRY ABOUT ANYTHING ELSE! OIL CHANGES? ONCE A YEAR! TRANSMISSION SERVICE? NEVER!!! COOLING SYSTEM FLUSH? ONCE EVERY TIME HALEY'S COMET PASSES THE EARTH!" BTW... BMW is known to artificially inflate their lease residual values so they can offer tremendous lease deals and sail them out the door in mass.... All they care about is you make as few warranty claims as possible during that 4 years or 50,000 miles - pretty much to the word what my former Mercedes service director told me they care about. Once you hit 50,001 miles, you're on your own. And pity the fool who buys them used when they've had four oil changes in 5 years.. Even Toyota has taken to recommending 10K service intervals. And if you frequent KZbin channels, check out The Car Care Nut. He is a master Toyota / Lexus technician who tells people the same thing your independent mechanic has told you, and the same thing I've been telling people for years. If you lease it for 2-4 years, then do whatever they tell you and let the next driver worry about it. If you want to keep it for a good long time, do an oil change every 5 to 7,000 miles with a good quality synthetic.

We're all sooooo appreciative of the fact that Eric never has to resort to any sarcasm in these videos...

[@rdaw33]

I used to work on BMW's, and on especially any of the turbo engines, any needed service or repair was VERY labor intensive. As I watch this, it gives me flashbacks to those days. I DON'T MISS IT AT ALL!!!!! Plus I had a manager who was kind of a dick.

[@justsumguy2u]

We went from a finely-crafted BMW in the last episode to one of BMW's modern-day failures. I too have no explanation as to why one main bearing would fail when everything else looked fine

Really enjoy these videos, lots to learn about how certain brands are engineered, failure points, or mechanical abuse or neglect.

[@muddywater6856]

I think Toyota says that is from machining debris in the twin turbo V6.

[@johngassmann9581]

Really cool engine and interesting to see the changes from the first gen.

[@batman607]

I had a bearing do that a few times, rods and mains, and I took a torch and heated the bearing shell up until the Babbitt melted and came off the crank. Took it to the crank grinder, he ground it down, weld it up and grounding back down the standard. Good to go :-)

[@ferrumignis]

Welding a crank?? That sounds like a good recipe for putting a bunch of static stress into a highly stressed area. Metal spraying would be the way to go.

It is hilarious that someone wanted to try to save used coolant and oil lines for a BMW. Everyone I know says they are automatically replaced as a PM item. And they are still using a plastic impeller on waterpumps? For an engine like this?? Nuts!

[@JohnSmith-pl2bk]

Plastic lasts for the warranty life.. It's now 10 years old and still going...3x plus it's designed lifetime! My 33 year old JDM diesel is on it's 3rd cast iron w/p with a stainless steel impellor and integral viscous fan hub All non replaceable except as a complete unit....

Agreed, you'd need to be insane to use second hand cooling parts on any BMW engine, especially one this complex and stressed.
