Really glad you left everything in the video. Breaking off bolts is extremely painful, and it really helpful as a hobbyist like me to see how you more experienced guys handle it!

Great video and explanations for tear down process of the engine.

12 mins in, this is probably your best video yet! I’ve been working on cars for 15 years hear and there, went to school for it even and learned a lot in this video 👌🏾

Had similar problems with my X5. Seized up in my driveway. Went to pick a part and grabbed a motor for about $400. Slapped it in and 60k miles later it's running strong. I've towed things cross country with it and it seems to run BETTER after working it like that. BTW those front differentials are junk. They just blow up unannounced. No parts available for them and the used diffs themselves are hard to find. I just disconnected the axles and front drive shaft and been running it as a 2wd for over a year. Def a love/hate relationship with these BMW V8s

Great video. Been thinking about buying a F10 M5. Kind of funny how rod bearings are issues throughout the entire bmw family. Had to replace the rod bearings in my Mini that only had 67k miles.

Great video! I have owned several ///M cars and always "lived in fear" of rod bearings.

Enjoyed it looking forward to seeing the outcome

240k miles on my 2010 X5M still running strong original motor and trans still, anything i should watch out for at this many miles? everything is seemingly fine haha for now

Played this game with my S63TU in my M5 at 81k miles. Shipped the whole car to Pure Performance in Houston. A touch under 14k and she was rebuilt and is still happy 14k miles later.

Just bought one with spun bearing. Looking forward to this project.

I'm familiar with that 'diesel smell'. It's the smell of burnt oil. Had a Ford shed the centre main bearing cap for some reason while I was driving @ high speed. Heard clank but the everything seemed OK for a while. About 5 mins. Later I i heard a clatter and simultaneously smelt diesel. Limped home and upon disassembly found the bearing cap lying in the bottom and a rod with burnt oil crusted on it. The stench was quite something.

Take the oil coolers to a diesel particulate filter cleaner place, they have ultrasonics there normally too.

Hats off to the work you do to these engines. Great video. I bought my X6M with 115k on it and through 5000 mile oil intervals and using the best detergent fuels, I now have 162,000 on it.

Well Nathan my engine as h may or may not remember is a n52. I put it up on jack stands to work through the issues bc quite frankly I got to much money and not to mention time in this car so I parked it before I fouled up something that couldn’t be fixed. Anyways when I did my oil pan gasket I noticed pieces of black stuff honestly looked like pieces of a gasket could that have been metal? I cleaned the pan with gas and they seemed to melt. I wish I had followed my first mind and done those bearings then. It just seems a bit complicated to me as to how to get the proper clearance. Also I was unaware this was yet another maintenance item til after I replaced the gasket. Thanks n keep up the great work

Dam. Feel sorry for the owner. Glad I decided to go for an e53 with m62. Vanos rebuild and timing guides are a cake walk compared to that.

The S63 was designed for a 50k mile corporate lease. When I look at this engine it makes be want an electric car. Change your oil every 5k. What a nightmare.

it looks like they've never changed the oil . If you want a reliable turbo bmw change the oil every 6000 miles. these turbo engines work at very high temp, thus makes oil goes bad very soon. Never turn off the car immediately after agressive driving because the turbos goes bad in that way. You have to let them cool down for about 2 minutes before turn off the engine.the Same goes for a cold start. When the engine is cold you have to wait at least 30 seconds before the trip, and never go over 2500 rpm until it gets warm.

Thanks Nathan for the Lesson. Question all the Hoses would it Help their Life to add a protective to them? I use to Work at Aeroquip and we made a fire hose shelve to help the Hose life. What do you think?

At 110,000 miles owners of comparable AMG cars are fitting blower upgrades. LOL Love the channel. I love all car repair!!

You have the coolest shop.

I thought I was going and have a nice 7 series in the end, but no, I bought a 2012 BMW 750Xi maybe an Alpine. It was a Copart purchase with mechanical issues, It starts and runs but has a bad knock. Thus far, timing chain test came back ok, but engine has one cylinder with low compression and I roughly measured piston travel through spark plug hole. I measure 6 out of the 8, couldn’t get #4 or #8. The cylinder with low compression also came up short on piston travel by about .3 inches. Assuming rod bearing .150” complete loss of the rod bearing would account for the lost travel. Will be pulling the engine, but am scared of what I will find?

What's the engine in the 21 M8 convertible with 750 horsepower? That had to be unlocked slowly I think it was like 500 horsepower and then it was raised up to 750hp after a break in time

Fracture cast is the word you’re looking for for the connecting rods and rod caps

Rod bearings in my 2012 X5M spun last year with only 49,500 miles. Meticulously maintained it & drove like a gentleman most of the time. Didn't matter. The bearing clearance from the factory is too tight. The BMW dealership wanted $36,000 to put a new engine in. Had it rebuilt with a new crank, King bearings, & ARP bolts, by the guys at Miami Engines for a fraction of that cost. Bearing in cylinder 2 looked like a pancake. Runs great now...fingers crossed.

If you maintain them they can last. I don’t care what anyone says. And learn proper driving habits. I bought mine with 80k miles. It’s turning 104k and runs like a clock. Turbos original and all. No wastegate issues or anything like that. I have the n63 though. 2013 m performance package with 458hp and 500lb/ft torque. Minor issues if you do preventative maintenance but it’s manageable at that point. I have the coolant plate leaking in my engine block ever so slightly but that’s it. I had the upper oil pan gasket leak at 88k other than that it’s a prestine car. It just make me upset to see these beautiful cars get beat to hell and left to die a tortured death like this X6M. This may be one of the very very few ones Nathan can’t bring back to life. Either way I still can’t wait to see what happens

I love my 6 cyl e39 even more now

Hi Nathan abit off subject but Iv got a e70 x5 3.0 sd , I hit a curb the other day and destroyed the wheels on right hand side so I replaced all the wheels with different ones now a lot of the time but not always when I floor it the dsc kicks in , any ideas? I’ve replaced all wheel bearings thinking it might have something todo with the pick up for abs in bearings but made no difference looked at wheel speed sensors with scan tool but we’re all within 1kph of each other and steering angle seems to be reading ok ! I’m no Mechanic and can not figure it out and not getting any codes ! Any help would be much appreciated! Top videos btw 👍🏻

Anyone got the conrod bearing bolts torque settings and procedure for this engine cheers 🤙

Hhhheeeyyyy im not the only one that's snapped a pan bolt!! Feeling your pain Nathan!

great channel my god I have a headache... this is why I won't buy or work on BMW or Mercedes products overly complicated for no reason and they always seem to blow up engines and the cost is just to much

I feel like I'm rolling the dice every time I start my F13 M6 lol, some seem to be very reliable with fbo stage 2 and 100k mi and some blow up stock with 40k mi. Mine's stock and 43k mi

ngl my m54 isnt fast by any means but for a car with 180k miles exactly its really fun!!!! also i saw a Champagne quartz metallic m5 pop up on facebook 88k miles seized engine would it be worth the and get a remand engine for it or just stay away from it he has it up for 17,500 and im max at 13,000 only because its an individual color and is fully loaded with every option.

Damn Nathan. How long did it take you to get that engine out? Thing is a beast! I'm not worthy.

Anyone know any reputable shops to do bearing swap on s63?

Them grindings are pumped through all the ports through the whole engine ??

Would that be an upper pan or a lower pan if the engine is upside down 🤣 I don't know how you can even attempt that job. Kind of like the transmission what would BMW charge for a factory rebuild or even a new one

What bearings should i put in my S63tu? I have 150k on it.

Put 150k hard miles on my n63 tuned bigger turbos and meth injection. Drive it like I stole it. The n63/s63 isn’t all bad.

Common Nathan on these that where not maintained 8k put another motor in the crank is shot? Can you see can it be polished

I wanted to ask how many miles should a cooling system refresh be done on a M54

To me the problem it's the oil pump chain, literally no tension and skipping teeth. Which will introduce oil starvation and destroy all the bearings simultaneously.

Sorry for random question, how long does the battery last on the Makita? Will it last a full tear down?

What source if any do you use? Alldata ?

How much do you think a full rebuild would cost the owner. Sure would be educational and entertaining to watch.

Why spend money on blackstone oil reports… just change the oil regularly and schedule a bearing change in your ownership… most importantly do not rev the engine or drive hard until the OIL is fully up to temperature… this is the same for Mercedes, Audi, Porsche, Ferrari..many high output / high rpm engine… they are not truck engines.

Aluminum bolts to save fuel lol so they don't oxidize I guess steal and aluminum does not mix good

The connecting rod process that creates two matching halves is called “Sintered”

So are you saying frequent oil changes wouldn’t have prevented this catastrophe?

If it's been sitting upside down for a while, it might not turn because oil could have hydro-locked a cylinder.

⭐️⭐️⭐️⭐️⭐️five star content

You're really fond of that ratchet you should try an impact gun I ake that back

One piece of metal in one of those hundred oil galleries and its game over. This is why they replace them at the dealer.

Yikes. I'll stick my e38. M62TU ain't all that bad.

Bearing material in oil coolers and lines, dude, you'd have to make sweet love to every part of this engine to get it running again. Car's not cool enough to justify that much work.

So what was the reason it is locked up??

Wow. These things make the M62 in my E53 look WAY better by comparison.

Lifetime oil. Or 20k mileage oil changes.

Damn bro engines don't look like they used to there's so many hoses and electronic things on them you have to wonder did they really just come to the end of what they could do to these engines and that's why we're going to Electric

So what version of s63 is this?

That’s what SHE SAID 😉😎👉💥👊

We tried to contact you about your extended warranty, you knew the risk....

I don't understand why you can not fix this engine. It takes about 4 to 8 hours to fix this engine. I've seen it done any number of times in DouYin(Chinese verson of Tiktok). The engine is still in good shape. You change the bearing and machine the crankshaft(need a machine shop) then it is perfect again. You are just not good enough for this job. You are just a parts swapper. Swapping parts is all you can do.

So I would assume buying a used 2013 X6M 88k miles With a Hamann exhaust and tune would be a big No NO?

Longevity and this engine don't belong in the same sentence. I've owned an M50, M54 and N55. They all had their own quirks, but this engine is big pile of s*%t lol.

You can buy a rebuild s63 with 2 year 100k mile warranty for 8k. Not worth paying to have you or anyone trying to salvage that clapped out motor.

Don’t know who in hell would pay $35k For all this work So it’s throwaway car after 80k miles

I would not listen to that Nathan

Tine for to put. Reliable engine in it. LS family way less more power for way less money

The sad reality of modern BMW engines. Audi, VW and Mercedes are not much better. Remember when BMW engines were really good? M44, M50/52 and the M60 3.0 4.0 V8. No big end failure, timing chain or Vanos bullshit. Everything since then has been a problem. M for Motoren, N for nightmare, S for sh...........

The solution from my Perspective. If you don't have the goose that lays golden eggs. Don't buy a BMW. 😁

this looks like n63

I cant understand one thing: You did so many hours to remove the engine and you wont simply machine the crankshaft to 1st oversize, swap few rods, change all the piston rings, replace the main bearings? Why man? I did many main+rod failures and they always run like a charm. But with BMW, I wouldn't think about installing the original bearings, because its clearly trash. 20 more hours and you can make a happy customer and yourself aswell.

sell it for parts and move on...

Who buys a used bmw m5? Why? These cars are meant to be purchased new with warranty.

Swap the engine with a V8 from Toyota, at least it'll be reliable, haha.

10k for eurotrash.. lol

Well.. my 2015 X5M just started knocking last week! What the actual fuck! 118.000km, stage 2 setup
