E60 M5 S85 Rod Bearing Issues | WHY The V10's Really Fail
Very comprehensive tutorial explaining some of the issues with the BMW S85 V10 E60 M5 motor that leads to premature rod bearing failure. This problem has 3 main reasons that contribute to the rod bearing wiping and I share some of my theories as to how this can be reduced or eliminated. We explain rod bearing clearances, oil viscosity and type, connecting rod thrust and side gaps and how all of these factors work in this supercar engine. This is one of the best saloon cars to drive and therefore understanding these issues can extend your driving enjoyment.

Mark,
In 2017 I had an E92 M3 6spd with 26k miles and always worried about premature bearing failure due to 10w60 spec'd molasses. After a lot of research at the time, I found info from a couple sources that BMW had followed Porsche's lead and unofficially approved the use of a thinner oil for non-track usage vehicles. Obviously, officially approving would have been a financial disaster. It seems that the heavier viscosity oil is always spec'd in anticipation of track usage and since most of these cars rarely see track duty, the ensuing bearing failure from DD usage was the end result. I was reluctant to go to the supposedly 'approved' 5w30 option and instead went 0w40 without any issues.
I've read the comments below insinuating that 'how dare you question engineering' but let's be honest, everyone's usage is going to vary and a race spec viscosity isn't going to fare well in a DD sedan.
Keep up the good work! It's from video's like yours and Timm's in the UK that allows me to entertain vehicles I would've previously stayed away from and missed the enjoyment. Just sold my 2019 M4 and bought a very low mileage E64 650i Sport and currently looking at a 29k miles E64 M6 cuz the wife likes the 650i so much. The new cars are great, don't get me wrong, but they don't have the same character or appeal to me or my wife.
I don't own an M5 but find this series very interesting. You have a Gallardo in the garage, but rave about the E60! A true enthusiast , keep these videos coming..
Oil need to get to a certain temp before you get 100% protection but boys get in and start up and foot on floor do not wait for engine to warm up !!
You can do that if u don't want the engine to work anymore ;)
Still buying one lol
I would do it all over again. I fall in love with the car every time I look back it or just drive it hard in M Mode. Cheers.
No love for a piece of junk.
I just got one for $7500. It helps when the seller doesn't know much about cars and doesn't have a lot of money to be throwing at it. That being said bearing wear becomes negligible with the use 5w30 or 0w40. But I wouldn't recommend the car to anyone who isn't either a mechanic or a blackbelt DIY.
Word
@@NickKautz I've heard that the v10 motor likes to be started with warm oil. I'll never own one but I doubt that the design or materials are inferior
Despite the e60 m5 problems, one day im going to be an owner of this beast. Great video by the way!
Best sedan EVER
Have u gotten an e60 m5 yet?? Asking because i want one too or the m6..
I love honda civics
Great video. I have been running 0w40 in my S65 for almost 100k Miles. Recently replaced the valve cover gasket so I got a peak inside the heads as well as the underside of the covers and they look brand new. Religious changes every 5k or sooner and stay on top of all fluid changes and maintenance like plugs and coils. Car runs better today than ever. Primary decat delete, BPM tune and she is a monster that will last many many more exciting miles. I can not wait to add a manual E60 M5 with the goal of eventually having the highest mile car of each in great working order. Keep up the great content, if only you were remotely local, would love to meet up and let you test my M3 for review.
Alex Martinez you cannot run ANY oil less than 10w60- 0 weight ?? That's insane. Wayyyy too thin
Anthony Michael you obviously have no clue what you are talking about.
From what i hear 5w50 is the best for s65/s85
Considering the RPM's, if you frame that as Revolutions Per *Mile*, Considering the power and displacement. 50-80K miles on rod bearing = 75-100k relative.
I live in Canada so what type of oil should I use the 10w60 might be to thick during the winter months.
Thanks for this video.
I'm planning on eventually getting an E60 so it's good to know the specific reason for failure.
However, since I live in winter for 8 months of the year, would this be a car I would have to keep in the garage most of the time?
Hey, what oil do u use in the beast?
bro what oil should i use if i dont drive very hard
That was some really good information! Thank you for that. Sounds like you’ve done quiet a bit of research on the matter and it made a tone of sense. Again thank you
Exoticcar great video! I really appreciate the time you took to explain all this and it makes perfect sense. Please keep up the good work.
We have a 2009 Interlagos Blue M5 and are at about 80K miles. Car has been damn near flawless but looking to do bearings soon. Great content thanks for posting.
+Scorny Motorsports thanks for watching and commenting. I also love the interlagos blue, stunning color in all light. Cheers.
On your e60 m5, did you do the 5w-40 engine oil swap over? ive been thinking about using 5w40 over 10w60.
Thanks for the information it was very informative. I’ve never been a fan of the v10 engine but always been under the impression that the v8 was a bulletproof lump,anyway you live and learn
It is a shame, it is such a beauty. I wish they had come with a dual clutch. The only buy one with a manual. 10w60 is what they have always spec with m cars. I would recommend a 0w40 Castrol , Penzoil, or Amsoil.
so what weight are you running in your M5 now?
Question, what type oil would you recommend me using for my 550i 2007?
VERY informative, thanks!
Dear Sir,I soo appreciate and thank you for such a fair and very clear explanation of this issue.Now, I just retired and have always owned and driven pretty hard my BMW's. Now as a retirement gifts I am getting myself a low-mileage 2008 e60 stick and also a low-mileage e92 which I plan on tricking-out( body-kits and all ).Now, my question and I more or less understand how engines work.What I need to know from you is, after what you've explained.....would it make sense to once purchased I should start using 0 -40 oil?Please ket me know soonest.Thank you,Roland D
Hi so i’m torn on wondering if i should continue a search for a 2007-2010 M5 which is also an E60 i guess? should i go for it and make sure that all the work has been handled and if not get it done? or should i look for a different car without a S85 engine? also love the videos!!!
whats the typical cost to have a shop do the rod bearings on a M5 ?
You do a great job of explaining this. I'm now a subscriber.
Many thanks for your support. Cheers.
Wonder if the oil recommendation with 5w-40 or 5w-50 oil is also applicable for the M3 E46 where BMW recommend 10w-60 witch is a very heavy and thick oil , if you do not track your car ?
What do the rest think or what is your thoughts / experience ?
5w50 would be good 10w60 is just insane for any car to run
What great content; thank you very much for taking the time to offer such great tips.
I agree with most of what you said but I find myself having to constantly add oil, almost weekly to my M5 as it stands with 10W 60. If we go lighter with the oil, wouldn't the car be burning that up in a heat beat? How could that be good for the engine? Let's not forget that the "10" number is just for cold starts depending on outside temp, you could drop that to 5 or 0 in the winter. But the 60 number may indeed be too thick in the long run but dropping all the way down to 30 is insane. How could you possibly think that this high revving 500 hp race car would take the same oil as a 530i? With proper warm up (10 full minutes) with the gauge red line getting down to 9,000 BEFORE you drive off away from your home, then bringing oil temp to norm, constant maintenance and oil changes, the engine will last forever!
Thanks for watching. Cheers.
@@ECPP Anytime, I love your channel but just trying to get the record straight. Also, maybe a dumb question but doesn't warming up your car properly, by nature thin the oil out so it can lubricate and get to all moving parts correctly? I would imagine that the idea that bmw had by making the moving red line on your tach was so that car owners could warm up the car fully to preserve the engine. I know the new school of thought is that your car warms up faster when driving but warming up faster is not the best way, warming it up longer so all moving parts get lubed adequately prior to driving and especially prior to harsh racing.
The couple M5 owners here use 0W40. They both have over 100k miles. We live in a colder climate, though.
Wat oil do u say 2 use
Great detailed video love it
Great ! Thanks for watching.
I had an E60 and with that weight of oil 10w60 I thought the motors where built loose from the factory with that weight required. Good info 👍
Thanks a lot for watching Tim.
Hi Mark, what oil do you use for the beast? Castrol has discontinued the 10W60 TWS oil and I'm looking for an alternative. Some people recommend the Shell Helix Ultra Racing 10W60, but it has no M-approval, the Castrol 10W60 Supercar does.
Ask BMW bud.
I like seeing ur channel grow Mark!
I love the e60 5 series well I dont own a m5 but I own a e60 05 530d and it's a wonderful car lots of tourq and reliability and an absolute joy to drive
What oil are you using?
Ive been trying to figure out if the rod bearing is a one time fix issue or a reoccurring problem which would make it a official default
Wait so, I was about to do rod bearings and I’m using 10w60.
But.. what if I change to 0W40 and let’s suppose the rod bearings have some wear… Will I still have to change the stock rod bearings? Cuz I changed the oil, what’s the point of changing then if 0w40 is gonna protect catastrophic engine failure?
Rod bearing change isn’t cheap you know
Hey Mark. What the heck are we suppose to do?
I have a e46 m3 and the e60 m5 and they are both using 10w60 and have been solid so far! Do you have any experience with the thinner oil? Thanks
ExoticCar PlayPlace Thanks. Blackstone lab analysis is sometimes higher and sometimes in the norm , so it's up and down... I've talked a couple of shops that do bearing on m's and they always recommend 10w60... but then again engine builders that I've talked to suggest going to a lower weight oil (5w30 , 0w40). I dont know what to think anymore. In the meantime I'll just enjoy the hell out of the car. Great channel , keep it up!
i hope you make a video on the difference between going from 60 to the new "recommended" 5-40 or 0-40 i would conduct a oil sampling with your current oil. and with the new oil change, see if you get the same or lessened levels of copper because of the new 5-40 oil change. it would be very interesting to see if the new oil really helps penetrate the rods and help create less wear. keep up the good work mark!
I had a e46 m3 I ran Mobil 1 from Walmart 15w50 . I changed every 8k and never had a problem. Bought it with 160k on it sold it with 195k was a great car.
Can anyone recommend a good BMW machanic in Charlotte NC?
Ypu got n m5
Thank you for this.. I'm shopping and being a mustang Cobra guy I'm new to bmw and want the luxury and performance
. And agree all day w the oil issue
Best of luck!
Great guy, thanks for sharing 👏🏻👍
So what oil do you run in your E60 M5? I just picked up one and running motul in it.
0w40. Trust me.
just got a m5 v10 103k miles for 20k$$ flat so thx so much for the info
Still going to buy one, is there any early signs of failure?? Is this in all e60 an issue?? I have heard of m5 with 270k on original bearings.
Sometimes a good mechanic can pick up a bottom end rod knock or send an oil sample to blackstone labs and they can tell you what trace elements of certain metals are indicators of worn bearings and may be found in the oil
Hallo this information is so helpful for me thank you so much sir !!!
Absolutely no problem. Thanks a lot for watching.
What about main rod bearings, I just changed rod bearings although I still hear a metalic sound on the bottom of the engine. Do main bearings also part of the issue, people are starting to mention that they also fail.
Its always a possibility but generally the lion's share of the stress and wear happens on the rod bearings, and the mains do no get much of the transferred stress and wear and tear. Typical rod knock comes from just that and the mains are not always obvious. That being said, could there be some other part, maybe alternator or tensioner pully,, etc.
ExoticCar PlayPlace appreciate the help my friend im thinking its the lifters
How many km on your car?
yea i want to change mine also befor some thing . big happens sooner
Super vid, bro.... thanks,... I still want an m5
Cheers, and you only live once. It did not stop me either. Have a great one.
Its not a bad car if you take your time to warm it up
I just took my pan off leaky oil line, my first middle bearing looks new? I'll check other tomorrow. I got ACL performance bearings. Car has 243,000Km
That’s awesome and would be curious to hear how they all look and what oil and weight you use. Warm up procedure would be good to know what you are doing
Hi Mark, I agree with a lot of what you are saying but my concern is that the s85 may run hotter at the crank than the new bmw's and maybe the other v10's which would explain why bmw use a thicker oil. I will be sticking with the 10w 60 in my E63 M6 for the moment
I think that is a smart choice warwick. I have always used oil additives for extra protection, like Prolong and more recently a far superior additive Turbo Maxx super lubricant.
5w30 for the break-in period(2k km) and 10w60 after that.Only those are allowed for the S85
Thanks for sharing
well explained. Good video！
Thanks a lot.
Is this the same for a 2007 M6?
Yes
Unfortunately, yes
Mark! Question for you. Will you be testing a thinner oil on your M5? I'm curious how the car will react to it. I'm thinking of trying it out myself in future. Thanks for great content:) 👍

Thank you for your video and support.
Marc M5 guru
This video is good for the culture.
Mark , have you already replaced your rod bearing? And are you currently using 5w 40 oil ? If yes are you gonna make a video if further in the future you’d not replace that part ? That was a great video honestly
Hi, No I have not done my own yet because I also only have about 53000 kms. I do use the 10-60 which I know is too heavy but I only drive in warm days and give lots of warm up. A thinner grade may very ell be in the cards, but I too have friends and acquaintenances who have experienced these bearing failures and I may also make a vid on this repair sometime in the future.
I think if you live in colder climates you are going to have rod bearing issues using the 10w 60. Mine has been in Arizona it’s whole life and had 10w 60 used every time and the blackstone labs report showed universal average of 7 for copper. Mine was at 6. Get your oil tested it is worth it. I have 114000 miles on mine.
I live in a cold climate and the couple M5 owners use 0W40.
Do you have oem bearings?
@@raymondchen6720 I sold the car because if there was anything that went wrong it was getting harder to find parts or I had to wait a long time. Have an f10 now.
I find it very hard to take reliable information from a Porsche guy about BMWs. Also you yourself had made a distinct point in another video to use the 10w60 as it also is a necessity for the vanos system to run as intended without risk of failure
^
and his grand theory at the end "o they figured out they could use thinner oil but then they couldnt admit this until the f10 even tho it was tru for the e60/s85 as well"..
ya maybe OR MAYbe they re-engineered the vanos system btwn the exx and fxx cars so that the vanos system could run w thinner modern performance oil ..
wish ppl would talk out their ass less on here
Great video!
Thanks!
Saw the video and read most of the comments...10-60...I leave in Greece where the temperatures are higher than most places and that viscosity is perfect for such a climate as ours. In colder places it might be "heavy" as the OP says, so go with 5-40 or even 5-30, fully synthetic of course. The climate is vital for the viscosity you use. Do REGULAR oil changes at 5000kms and check your oil level regularly to top it up. Bad mentainance from bad owners destroys the reputation of such high performance automobiles. Buy a good one and enjoy it!!!
Thanks a bunch for your input. Thanks for watching. Have a good one, Cheers.
What do you think about using 5w50 Mobile1?
I just bought a M5 with a blown motor.. and it's still reading like the oil is filled.. I can tell the design of the oil pan is bad. The front pick up most likely starves out causing the rod issues.. when I Finnish my motor I will keep just a little extra oil in it..
That Quasi dry sump is not as good as a true dry sump like in a Porsche, Ferrari, or Lambo.
So on my next oil change should I down grade to thinner oil ?????? I Haven’t changed the rod bearings
what is you mileage one your m5 .
93,830
I am a wrench-head and proud owner of S-Chassis too, those are my daily drivers. I know I'm going to get a lot of flaming, but I don't rev, drift nor do I race my M5. I'm normally drive it on P400 and adrive it 2x a week, It's an 08. I really try to baby it. I just recently been thinking about getting the rod bearings changed. But my question is, if I baby my S85 motor while driving on P400 would I minimize the possibility of engine failure or is this prone regardless of driving style?
Jr Zendejas-Ruiz it wont matter
Beat on it
Thanks
You are welcome
It make sense now, 10W-60 is ridiculous for a car with tight clearances such as this. I totally agree with you and would run an 0W-XX... 0W-40 sounds good. Most 0W oils seem to be very good. I run 0W-20 in my Type R (actually the factory recommendation) and I refuse to run 5W-30 or anything heavier even with my upgraded Turbo I will still be running 0W-20 specifically Motul 300V. I would plan to run Motul stuff in a BMW as well... I am looking at getting an E60 someday for myself, I won't let these reliability issues deter me from experiencing that wonderful V10 with a 6speed. The new BMW turbo engines are cool, but they don't stir my soul like this high revving V10 does. Whatever my next vehicle is needs to be something high revving and aural... it won't be an S2000 because I had that already. Whenever I get an E60 before I really drive it it's going straight to the shop to get the bearings replaced... so I just have to factor in repairs into the purchase price of the car.
Absolutely great choice. While the v10 is not real reliable, it is a gem and in my opinion, will be sought after soon as all vehicles are starting to sound like vacuum cleaners. We still only have 58000 kms on ours and should do us well in the future.
There are so many issues that can and will come at you; all costing thousands. SMG pump, clutch, every part of vanos, throttle actuators, bearings. Then you get to the every day car stuff like suffering 10-15 MPG, insurance. Then, you are paying the premiu///M for tires, brakes, bushings... For a 10+ year old car! I love the e60, everything about it! I have wanted one for years, been on test drives, searched and researched... Contemplated and decided I NEED one. But have not been able to pull the trigger, it's just is too risky. A literal game of Russian roulette. Buying it could be super rewarding, or it could be financial suicide. You might buy one and not have any issues, or you might buy one and have to spend 15,000 in maintenance in a single year in a car that looks new and has been meticulously maintained... At that rate, you would be better off buying a Lambo or Ferrari. It's to the point now where a 2015 M4 would cost about the same as an e60 M5 when you look at total cost of ownership on a yearly basis. I'm looking for a car with a budget of around $50,000, not a daily, just a toy. And I always come back to the M5/M6 with that v10, even though they're much less than that. But can't justify actually buying one.
get the alfa gulia QV manual, with a Tune will be faster and the V6 easy and cheap to fix compared with v10. this is what i will do. i will pass this one, the e39 m5 is better than this one
$15,000 in maintenance ?? lol what are you smoking ?? lol I own this car its no worse then a regular car 'if' you are smart about where to get your parts for maintenance. The car as given me no more trouble or expense then a Toyota since I had it, and i replaced the dreaded actuators for cheap. A fool can go bankrupt with any car, a smart owner can enjoy this car for little money.
31 acruz: how many KM u have on your engine?
50k bought it with 30k and I drive it everyday, summer and winter, go skiing with it, and mountain biking with it, great car reliable as a rock
the guy above doesn't have the balls to buy it, and its just projecting his fears to everyone without even owning the car. He will always be a watcher while others do the driving.
Is motorkote good?
Yes
Bmw should of at the least, addressed this serious issue, at the most build a high revving engine, with absolute precision. However, these cars are for the elite who lease these cars for the 3 year mark, then they hit the used market, it, s everybody else issues. Not good bmw. I have to stay away, due to the issues. Buy these cars, they are great cars, performance is stellar, but be prepared for these issues. Im glad this video exist, the public needs to learn the truth.
Is it the fact that the crankshaft wears egg shaped and this is the problem ,!!!!
Love this guy, grow the David Lynch haircut!!! 😊
Thanks a lot, mucho gracias.
@@ECPP You're genuine, indeed you know you're stuff. But there's no adjenda, no BS.
5w40 is a good balance..
trustgtr33 5w50 is better
0W40 gives the best protection for this motor.
I've ran 10w60 in both my s54s since new. No issues. Replaced bearings at 65k on both as well. I'm just about to dig into my s63 in about 2 months once it ticks over 65k. Let just be honest either do the maintenance or buy a less performance oriented engine rather than complain about what someone should have could have but didn't.....
I've watched brand new engines detonate on first start/break in.
Did I mention a Latvian tech who assembled s54s in the plant gave me a tip.....
Let your lubricants warm up not much but not cold before you give it the beans otherwise premature wear will occur in every BMW engine. Think not ....?
I've owned a dozen and all still ran perfectly or within spec tolerance so.....
Nice
Mark, i have a 2008 Lci now on 60K , ill be having the bearings replaced next month by a guy who does around 15 x S85 a year (bearings) he has done 44 x S85 bearing jobs.. 122 x S62 and 89 X S54 bearing jobs and he says 10W60 , the new M5 is not a high rpm car and there is no need for the 10w60 oil..
Sure Mark no problemo.. will be eind of may that ill bring the car in, but ill report back , car runs flawless and never had a single problem with it, so im very very interested @ how the old bearings look.... ill report back when i have news.. good video BTW... ive also read a lot of posts on m5board about what oil to use... and its a very debatable subject :D
the new M5 is not v10, it's v8 and it's turbocharged. Now bMW has released the "allaround" new BMW oil which is 5w30, in my oppinion that is wrong. Turbocharged engines also need to run with 10w60, if you want to keep your turbocharger safe and not consider it a maintenance job like brake pads.
Very simple. The same happened on those 2.7 dodge intrepid s. The solution was to grind or polish little more than specs the journals but of course eveybody at the end junk those cars since it was not worth a rebuilt.
But there’s even more. These idiots thought it was a good idea to put the water pump inside the engine. It’s stupid to put the water pump inside the engine especially if it’s driven by the timing chain.
Doesn’t the M6 E64 have this same problem?
Even i want to know, i plan to own one someday the exact same convertible soft top E64 M6
Yea has the same problem. I’ve owned mine for a month now and did heavy research. Go look up Troy Jeup on IG he knows his shit on the S85.
Heat is killing Rod bearings two for sure I have a2003 bmw 540i and every time I did oil change in my car I saw a tiny copper pieces in my oil filter after I modified thermostat for a lower temperature problem solved before temperature was 110C and after modification in very hot condition hits 90C . So I was lucky to figure out this and save my engine .
dude thats suck because that cars is a hell of a ride when driving on the limit
brilliant
Thanks
Switch to Motul ester 5w 50.. Been running for 20000 miles yet
Good stuff
Probably a measure to aid the emissions system function. Slack NA engines are inherently less predictable per given ignition timing and that is partially critical to a cleaner burn.
Doug brought me here :)
Nice. Thanks to Doug.
Me too
V10 is race engine that's built too tight.
I wonder if could take the engine change crank an rods to Honda spec an see what happens. ??
The S65 may be a bit more reliable, since it lasts a little longer the S85.
Rod bearing failure happens on the S54 as well, but not so much.
For rod bearings to be replaced on the S65, it should be done after 100k miles.
We still ALLLLL want one…!!
Absolutely, still an amazing car
Good works, rod bearings tolerances are too tight. Need a low viscosity oil for proper lubrication.
Do you drive an M5 ? Thanks for watching.
I like the fact that most of BMW drivers are engineers. I also hope that real motorization not die for the next 25 years.
I’m replacing the rod bearings sometimes next week. My M5 has 101k on the odometer. Im doing this as preventative maintenance. Sooner or later it has to be done. I Just order the parts and now just waiting for the shop to call me in and have the rod bearings replaced. I will let you know how it turns out.
ExoticCar PlayPlace will do.
Juan Milo u say 101k
Is the miles or km
Neil Burton. It’s miles. Sorry for the confusion
Make sure when you report back, don't be stupid and hide the price of both parts and labor. Aso tell us how the car "felt" before and after. I see so many idiot reviews where the guy tells us all kind of irrelevant moronic stuff about his personal life and nothing about what "we" as M5 drivers care about. How much were the parts (I noticed you already knew it and already missed the opportunity to give us an idea of the price), how much was the labor, and how did the car feel before and after. The rest is window dressing
31acruz Turner Motorsport website lists the complete rod bearing package for $1442.00., I am interested in labor cost also realizing it may be different from garage to garage.
Very informative video on the rod bearing issue mark! No engine is perfect, i still think the V10 in the M5 is a piece of modern engineering. currently there's a class action lawsuit on the bearing issue against BMW on both the M3 and the M5. luckily now there is an updated rod bearing part that meets the new clearance requirements. The kit is about $800 not including installation from a specialist. I do agree on the oil though the 60 grade is too heavy for this engine. now if you wanna know if you have rod bearing problems i suggest you get your engine oil analyzed and see if you have traces of copper, if you do, i would drive the car normally and don't be aggressive with the revs. And always, always wait until the the engine oil heats up to proper temperature before you press the pedal all the way down. likns down below

Now if you want to do it yourself here's a very good detailed walk through on changing the rod bearings. and i only recommend it if you really really really know your way around an engine and have lots of experience.

Thanks for this info Julian! I just wrote a comment saying there should be a class action on BMW for this issue. I might end up getting these updated rod bearings if/when I have to replace mine.
Yeah lets trust the Blackstone report to see how far the bearings are... if that report helps you sleep better at night go ahead.. but dont bet your life on it.. :D
how the hell is too heavy if it's recommended by BMW engineers ? guys, stop listening to anyone on the internet, and read that manual ! I owned lots of high powered cars, including a 321 cp 2.0 turbo engine modified to stage 3, M5 e60 which had the same 10w60 oil recommendation. I encountered zero problems with both cars changing the oil at 10000kms and even less if you like to floor it most of the time. Also if you are cheap with this car, it will behave cheap with you (you get the point). Remember that VANOS system uses the high pressure oil to move the camshafts, and also oil is used for operating the lifters, not just for lubricating.
I reckon the use of lighter oil in f10 m5 engine is not because oil tech moved on or bmw learnt something
In my opinion it is definitely more to do with the fitment of turbos
I've got an 06 with like 112,000 miles on it. I've read on the boards (so grain of salt) that these bearing failures tend to happen in the 50-70 k mile ranges as you said and if you get past that you may be okay. Like maybe some of the engines had bearings closer to the ideal 1.5 thou tolerances rather than the 1.3 that's killing engines? I don't know. Wishful thinking. I've considered replacing mine but I'm not sure if I'd trust a disinterested independent shop to really do the job right.
how is your M5 doing is it still alive Gavin?
Plastigage is not accurate enough to distinguish .0002 or 2 ten thousands of an inch. I do agree there is obviously a known issue with BMW motors, and many point at bearing tolerances, it there are many factors. Obviously a high performance motor with an expectation of lasting as long as a normal sedan, may be a challenge for any engineer. my 2 cents anyhow.
Good point and thanks for watching.
I have a theory that the clearance is too tight for the oil viscosity and apart from that people don’t warm up their engine
The F10 M5 has bearing failures as well.
There have been some catastrophic failures there
On the f10 the injectors fail and causes the cylinders wear and the engine to use oil. When we replace s63 engines bmw what us to replace the injectors as well. The face lift f10 engines(s63TU) is better with this isue fixed.
You have tolerance that's way too tight, oil starvation and evacuation, excessive heat then you toss in drivers taking the engine to recline and kaboom there goes any chance of reliability.
True
If I bought M5 or M6 with 1 or 2 owners And I'm not shore how they took care of it I would change them 100% and also change all oil in this car. I want fresh start with my Baby:)
Probably safe approach.
Yep. Change the rod bearings and while you have the engine out, you can coax a little more power with forged pistons, rods and some head work.
@@williambex967 you don’t need the engine out to do rod bearings
Stellar money pit .😁
Fun like crazy though.
@@ECPP You mean your wallet never hurt so good 😂👍👍👍
Probably the biggest endless money pits of all BMWs.
Seems like just putting a thinner oil will solve all the engine reliability issues...
It's the clearance, Clarence.
Mark perhaps we should round up as many E60/61 owners & email the ceo of bmw, if no reply can we do a class action movement / lawsuit ?
BMW designed to only last during the lease period. They are disposable cars.
