How does a 130,000 mile M4 engine look inside? Evolve S55 Billet Crank Hub Fix
HTML-код
- Опубликовано: 6 фев 2024
- Matt bought his F82 M4 with 125,000 miles on, and has done 5000 trouble free miles (other than 2 oil top ups...)
We were curious to see what the inside of the engine was looking like after that many miles, and having only been serviced to BMWs service intervals. Combine that with the small niggle of crank hub slip (although unlikely to ever happen with the plans for the car and how I drive) it seemed a good opportunity to upgrade the Crank Hub to the Evolve 4 pin billet hub.
We show the entire process of the Crank Hub upgrade, along with a detailed explanation of the issue, why it happens and how we have fixed it.

It's mesmerizing to me watching a skilled technician at work. Brilliant stuff Evolve 👌👌
You need to start uploading every week with series like these, they are very interesting.
That’s our plan!
OMG.......as soon as you see cellophane wrapped around the front of a car, you know your car is going to be looked after ..........really well☺
That's just for video
yeah but its the guys own car ,not a customers
11/10 for the atmospheric D&B soundtrack, class.
Love how you’ve chosen that, big part of my life back in the day just like BMW M cars were. We put on Scotlands first D&B clubs back in the 90ies. LTJ bukem days ❤️
Hard to beat when pairing with a Timelapse!
Fair point!
Keep up the good work love the channel ❤
Sounds like when you are queuing for a ride in alton towers in the 90s, maybe Oblivion. Top stuff.
I dont own a BMW but love watching your videos, the attention to detail is first class
The camera work is insane! Well done and thank you 🔥
Thats a great solution guys. Love to see quality innovation and parts in the BMW tuning scene. Great videos as well
Brilliant to watch a skilled technician at work. The photography and time lapse exceptional along with a fantastic explanation. Always a pleasure to watch the team at Evolve at work!
Top notch video quality , explanation and technician 🙏🏾
basically proper engineers who have come up with a good solution.
You made it look super easy! Excellent work by the technician! Thank you for sharing this information with us and providing solutions and upgrades for our cars!
great video as allways, and the music is spot on!!
Very interesting with high learning value Imran and of course the work and skills of your guys, just amazing!!!!
Guys it is long past midnight in the UK 🙂
Great video as always !! Greetings from San Diego California
Great fix bro 🙏🏾
Great video, and an excellent explanation.
Great video! Glad to see another S55 project, since I have an M2C. It never ceases to amaze me how car manufacturers can somehow convince themselves that designs, such as the crankhub on the S55, are adequate, when they could be significantly improved with only minimal incremental cost, such as using a keyed hub rather than the friction washer. Looking forward to seeing the video about changing the rod bearings.
Most probably designed that way so when it fails, they want the customer to go back to dealer for a new engine
@@JordzyBrev No, they don't want that level of warranty payment to the dealers or the reputational hit. BMW lost a lot of money trying to fix all of the N63's issues after the fact. Its mainly cost shortcutting or unnecessary engineering risk.
@@justinfrazier9566 Yeah this is a constant stupid take I see. They act as if the service cost goes directly to BMW lmao... If it would all car companies would make their cars unreliable as FUCK.
Great video!! Keep videos like this coming
Absolutely love your videos just wish you could do them more frequently 🇬🇧👍🇬🇧👍
interesting as always imran keep it up!!
Great content M'A
Great Video! I cant wait to bring my F82 (and G80 after the run in service) over for some work in the very near future :)
Great info
Jeeeeeesus what a job !
You guys doing exactly what's been done on Spencer Berke video
Nice Zelos Imran!
Thank you for the video. It makes me appreciate my Toyota even more 🤣🤣🤣👍👍👍🇬🇧🇺🇸🇬🇧🇺🇸🇬🇧
Satisfaction 👌🏽
Apart from the great mechincal work, great attention to details by having the protective film around the front end before doing the work. It's always painfull to see the clothing rubbing or banging onto any cars during any work around the engines
My friends M4 has over 200000km and it is driven extremely hard every day, everything is still original and it is still going strong!
I would say the S55 is the most reliable and robust M engine yet!
Little bit less mileage than this, but great to hear it's being driven hard and still going well :)
that we've seen so far...the S58 can prove to be bulletproof now that the crankhub is not an issue
stock engine is fine, high power ones problem.
B58 is better then s55
@lukeskywalker1666 it is by a mile but he talked about an M engine.
One hell of a job getting that sump off. Rediculas that so many items have to come off the car.
Besides the rods also the valves and pistons etc. would be interesting to see after 130,000 miles👍
That is the mightiest torque wrench I’ve ever seen, shit looks like Excalibur 🗡️ 🤣.. nice work on the CH👌🏼✅
A+ guys
Over the video! I’ve had it done but didn’t get to see what work went into it!
Any arguments against spline driven crank hub, why did you lads choose to 4 pin instead?
Excellent coverage and love the fact you’re documenting this so much over time 🙏
We have never personally fitted one, but have heard many reports of the spline type hubs failing. We’ve been fitting 4 pin hubs for probably 4-5 years now and have not had one issue, including many high horsepower/track builds.
Was going to say. I'm more interested in the condition of big and main bearings, along with bore condition and cam lobes. Hopefully see this in part 2.
To see the main bearings you would have to dissemble the entire engine, which we aren’t going to do. We showed the cam lobe in this video, they’re in quite good condition with the odd faint scratch but certainly nothing to worry about.
Holy effin crank bolt wrench!
Absolutely great information and detailed explanation of this problem . Love the way you/ your company design the solution. Do you know of any manual F80 stock configuration that has spun the crank hub?
Thank you! We don’t see many manual cars in personally. I don’t think I’d be too worried about a manual car at reasonable power levels but I’m sure it has happened.
Evolve, not to be confused with EV-love !
It's definitely ok now
Imran am I right in saying the crank is torqued to 600 FT-LBS from factory 🤔
Great fix this bit of this was checked regularly it would possibly help it from coming undone🤔
Great work Hash, plenty of it to do this job!!🙄
This is definitely a big part of it, and why we see some people do for example just the crank bolt guard and then have issues, likely cause of incorrect reinstallation. However if they had left it be it might’ve been just fine. Obviously any sort of upgraded turbos or maxing out stock turbos with E85 I think it’s a great idea. However highly beaten on cars like the Apex Ring F8x cars never get the fix and they’ve had zero issues. However they’re also driven properly for the most part. Theres a lot of different variables with the hub. Approaching 100K on my S55 with zero issues, daily driven like it’s stolen ;) maybe my car was just properly torqued from factory. Also am within factory power on just a CS map however with definitely plays a role. More power simply means the hub is more at risk to slip, no matter which way you spin it in.
I have a hybrid turbo f82, with 80k on it running about 600 whp. No hub fix, absolutely fine so far. The problem is overstated. I think big power, SMG box and aggressive down shifts are probably the combo that makes it slip. I also agree some of these fixes (not this one) look a bit dodge, I recon the issue could well be more common for people who have messed about with there crank hub than not.
nice
They probably did it to catch out people that run tuned cars. Figured out @ xxxlb-ft of torque impact , the friction material would slip and they wouldn’t have to pay out to fix. Then they started getting warranty claims for non-tuned cars due to dct behaving differently to auto and they fixed it to not risk it with next vehicle line
a nice fix, car manufacturers always seem to stuff something
Great video! Any plans for intercooler upgrade? Personally I’m considering the Wagner Tuning one.
Nothing with the current plans unless the standard one fails
Would love a S58 Achilles heal breakdown! I’ve heard the stock manifold cracks at around 30psi. I really and to get a G87 in a year or so.
So far the only thing does seem to be the intake manifold if wanting to go hybrid and push higher PSI, then the transmission.
If sticking to standard turbo power (which is still capable of a lot!) then it seems a very reliable well designed engine so far.
I thought Gintani was the first to come out with a pinned hub for the S55 way back in the days ?
Superb content and production. Have you any advice on PCV issue, can the valve cover just be replaced as preventative maintenance ?
We haven’t experienced much PCV ‘squeal’ on these cars. Matt’s does not have it currently.
It also happens to the first M engine s38 M5 M6
Just wondered why you would not do rod bearings while it is all apart 🇬🇧👍🇬🇧👍
Find out in the next video if they’re worth doing!
Really useful video, thanks. I have a manual M2 competition stock power. So, possibly not likely to be affected too much?
It’s quite unlikely with that combination
What I would like to know is, why would BMW not key the crank hub from the factory?
How come the coolant has to come out ?
do an f90 m5 transmission fluid change plz
why would they ever do this??? - You're solution is correct sir.
Wait you gotta do all of that just to change the crank hub?
How often does Matt change his oil? It would great to know his service regime as the engine is so mint
Matt has owned this car a few months, before that the car was serviced by BMW to their intervals.
Ok but did we fix the issue of the bolt coming lose... no
Great video, how much would this job cost ? And at what stage do you recommend doing this
We strongly recommend this for any customer wanting to go hybrid turbo or for DCT customers who may be using on track with heavy downshifting.
Price can be found on our website - www.evolveautomotive.co.uk/products/evolve-pinned-crank-hub-bmw-f87-m2-competition-f80-m3-f82-f83-m4-s55?_pos=1&_psq=crank&_ss=e&_v=1.0
The only way to get rid of that oil varnish is to change your oil at 5k kms intervals with ll4 oil
Curious what he did for maintenance to have it look that clean after that many miles
It was serviced by BMW to their intervals, but I think truthfully it also hasn’t been driven that hard which I imagine contributes to it.
Ok now I understand why this is a $3k job lol.
I really like these but can’t see me buying one, I live near the Lake District where it’s wet and muddy on the roads 95% of the time, I’d never be able to go full throttle without ending up in a hedge or wall. Wish this generation was 4wd!
It was built for stock power. I obviously only fails under modification.
Such a ball ache though going through all that to do the crank hub fix. So many parts to remove and put back together. I guess that’s why a lot of people don’t bother? What’s the cost for doing this???
It’s not a small amount of work but the only way to do it properly!

How is that an 18 plate a pre-facelift??
We explain that in the first video 😉 Built 11/16 but not registered until 2018
Is this necessary for a stock s55 engine? Rumour has it the future proofing weakens the integrity of the crank hub
Very clean internals, does evolve recommend engine flush at oil changes ?
Using good quality oil and changing regularly is more than sufficient in our opinion.
Is 5000 km sufficient for oil change interval in s55 engine?@@EvolveAutomotive
@@michalalewicz8570 you can't change your oil too soon, so every 5000km would be keeping it very fresh.
Is the crank hub a problem on the N55, or is it now powerful enough to shake it loose?
In theory it's the same design but we haven't carried out the fix to our N55 M2.
Was the timing chain changed as well or not required? I saw on your website that you offer to change timing chain as part of the crank hub change. Thanks
We did the timing chain on this one as it was high mileage. Didn’t overly show any signs of stretch but worthwhile preventative maintenance.
okay thank you@@EvolveAutomotive
Any thoughts on doing rod bearings while you have the oil pan off?
Stick around until the end of the video 😉
@@EvolveAutomotive Oops, lol
How much is a crank hub with installation for an s55

Can we get Matt an Eventuri Intake?
I promise I didn’t ask for this to be written but maybe one day 🤞🏻🙏🏻 it’s what the people want Imran 😂
I take it the n55 (m135i) is different then ?
No, N55 and N54 both share this crank hub design
I would have just pulled the motor doing all that work in frame
If I may ask, have turbo M cars ever suffered from Rod-bearing failure? 🤔
We’ve done quite a few F10 M5/M6 rod bearing changes now. This car was the first S55 we have done and all of our findings will be in the next video.
It’s certainly not on the S65/85 scale of issues.
quick question this is a 18 plate and it dont have lci tailights
We explained this in the previous video, but it has an 11/16 build date but wasn’t registered until 2018
@@EvolveAutomotive ah ok makes sense now thnx
BMW should have made the crank hub repair a factory recall
Would love to know the cost of this mod. As im local.

How in the hell did BMW reckon that friction material would work indefinitely?
I don't understand why bmw would design the hub like this and why did they not make an update and fix this issue?
How much does it costs?

So the crank hub still hasn’t failed at 130K. Good to know.
Truthfully we are unsure if the age/mileage of the car meaningfully affects the likelihood of the hub spinning. There’s many variables and whilst we’ve considered a way to test them we aren’t sure if the data obtained would be useful as advice.
@@EvolveAutomotive I have a stock 2015 F80 m3. 22K miles with BMW Full service history. Hopefully mine will last as long. Had a drivetrain message come up the other day but now disappeared.
Hopefully it lasts you a long time, enjoy it! 🙏🏻
how many engines have you really seen with spun hubs?
We have one in the workshop with one currently that luckily didn't spin it enough to cause engine damage. Our F80 M3 had it happen at 1000 miles on the dyno which required a replacement engine, and we've heard of many more.
back in the day not all engines were built so that if your timing belt skips(kinda same as spun hub) then piston meets valves.
if that happends, sh!t gets expensive real fast
@@EvolveAutomotive
Bmw knew better than what. Soon as my M2C warranty is up it’s gone.
I noticed you said miles instead of kilometers, why is that?
Because it’s in miles? 210,000km
I was just always under the impression only Americans use miles so I was thrown off hearing someone in the UK refer to it as miles, rather than kilometers.
Nope, we use miles too!
Mind = Blown.
By the way, love the content and love the Eventuri intake on my F80. Thing is nuts. Also had one in my E92 M3. Exceptional products.
Looks like an expensive labour cost alone 😂
If i have money i want to buy m4 or m3 touring and send to imran ...750-800 hp is good enough for me tho 😂
for the cost of this just buy extended warranty and use bolt on mods that can be removed lol
So fraud? Good plan.
@@EvolveAutomotive that’s your choice of comment lol… you’re advertising that this is safe and offers “piece of mind” on “high mileage vehicles”. Even with your so called fraud comment getting extended warranty compared to this over “piece of mind on high mileage” is hilarious get real buddy
@@EvolveAutomotive you mentioned that the bolt will come loose too… does the same thing happen with this kit over time? Probably. Great fix
@@EvolveAutomotive regardless I’m sure it’ll be noticed that it’s a common issue on s55 should the customer really be at fault and not covered? Depending on the length of modifications done and mileage is it really justifiable to call it fraud over a known defect especially when you say it was fixed in the b58? you sure are funny
130k miles ? On s55 that gotta be its 2nd engine
Original engine.
The idea of drilling into the crank with a hand drill and a guide makes me feel uneasy, there's no way that is perfectly centered down to 0.0001". I'd love to see how much the balance is off on the crank after this mod. This falls under "ghetto fix" for me imo.
Where did you get your 0.0001" tolerance from? Is that BMW's own spec?
@@LCOF bmw doesn't have a spec for centering 4 holes onto its crankshaft, but if you want to drill 4 holes into your crankshaft without balancing it later you better be dead on
BMW mechanics are the best - they get the most practice. Toyota/lexus mechanics are the worst - they have to fix imaginary faults.
😂
2jz with half mil miles makein 800hp this is nothing impressive 20 years later bmw struggling to make something reliable lol
I'd rather let it break and then buy a new car instead of doing all this.
Then you have more money than I 😅
Bmw engines have so many failure points, makes a range rover look reliable.
BMW is in the top percentile of reliability. Stop spreading miss info. The car in this video made it over 130K with no crank hub failure. It’s just a preventative measure for adding more power.
BMW.... Where changing rod bearings, motor mounts and crank hubs are regular maintenance. It's like a scam to own one of these cars.
