#BMWS55 #S55ENGINE #BMWCRANKHUB - Авто та транспорт
The majority of the crank hub is for manual cars and them money shifting, which you are correct, it is the hard shock that loosens the crank bolt. There are no recalls for the crank hub issue. Also less than 2% makes up the crank hub failure but I would get this fix if it puts anyone's mind at ease. The 2017+ MY got a different bed plate, thus from BMW should have less chance of a crank hub failure. There is a Bimmerpost thread on how many have had the crank hub issue and those are just who we know but it wasn't many, again 2%. Of course there are also undocumented crank hub failure that is not accounted for but 2% on a forum, and also no one I know of except 1 person that I heard of that had this issue in 3 of my M groups / clubs puts my mind at ease for the failure not being common.
The DCT is solid as far as I know. I am in a few of the M groups / clubs and nv heard of a DCT going. I think the IC and the oil cooling should be upgraded for prolong track days but not a once or twice a yr kind of thing as the air to water cooled IC is pretty optimal and wayyy better than the air to air traditional IC. I believe majority of the issues are known on the N54 and N55 and not really the S55. Yes there are also oil leaks and from the oil housing gaskets and valve gaskets but I rarely see that in my F8x group. I myself am at 40k miles and stage 1 BM3 and the car has almost no metal material for the last Blackstone analysis. I also have an interval of 5k miles or 1 yr oil change instead of BMW's recommended 10k or 1 yr.
One thing I would definitely say is that for those that opted out of the carbon ceramics, better brake fluid such as RBF 600 should be replaced b4 a track day. It was mushy after a few heats of 5 to 10 laps for each heat. When my rotors are done, I'm going with Ferado DS2500, StopTech pads, and stainless steel brake lines. We S55 ppl definitely should not have rod bearing problems like the S65 and such the V10 M5. The S55 is pretty solid.
Just some clarification on the crank hub issue. The owners who have experienced this have almost all been tuners. If you are maintaining a stock setup, you probably have nothing to worry about. I have 75k miles on a 2015 f82 with zero engine issues. I’ve owned bmws with both the n54 and n55 engines and this engine by far has been the most maintenance and problem free of all the engines. BMW has a winner with this engine.
Do you think a stage 1 tune would make the crank hub spin?
@@tigeralpha1480 yes, happened to my friends m4 despite him being warned.
very cool!!! How is the N55? I have 77k on mine. solid engine?
(it has been maintained well.)
But the problem is in the S55, right?!
Dean, love your vids, and followed many of your suggestions. But, I've owned several BMWs and have never had one oil leak. Am I just lucky? Also, my most recent purchase was a 16 B6 Alpina. Will it have some of these same issues, or do the Alpina upgrades like mahle pistons, larger turbos and intercoolers, etc. fix several of these concerns? Thx
In the future I think this is going to be remembered as one of the best last BMW petrol engines
It is sad, but true!!!
S58
B58
B58 and S58 are far more better engineered
Also paired with that racing dct transmission which is second to none
I have an M3 Competition 2016 since it came out. NEVER had issues, 25k miles and going.
There is even a few reliability aftermarkets upgrades for this engine too. Glad there are aftermarket brands making BMW reliable.
Hi m8 just just looking for some advice I bought a 2018 bmw M4 competition 31000 miles of bavarian bmw 1 years warranty and I am worried about the famous crack hub issue is it covered under there warranty if it fails. Advise appropriated thanks 👍
I owned and driven 6 BMWs inside family, can't remember one leaking. Currently daily drive an F80 Competition and watching this one would think they leak everyday. I'm no specialist but from general opinion if you change the chargepipes you pretty much good to go while having that crankhub in mind.
Hey, great video by the way, I just wanted to ask you, what you think about the BMW V12s?
Good shout on the recalls, always a must to keep checking your car for recalls. Not sure if I am the only one here getting that impression from what you are saying - to be able to actually drive these cars in anger you literary need to replace most of it? LOL Also, did you said like hundred times in one of your recent vids "never remap BMW cars"? ;)
Would you recommend doing the gaskets for the valve cover oil pan and the oil filter one like every 60k miles? Is that like a good bench mark milage to fix these issues before they leak or would you recommend it to be done at 50k miles
No, I would replace them once they leak. I wouldn't let them leak for a long time! But I'm just saying I would try getting the full value of the gasket until it fails. No reason to replace a gasket that still works. Especially for the oil pan, valve cover and oil filter housing. If those gasket fail there is no major damage, it just leaks oil, that being said I would wait until the gasket fails to replace.
I own a n55 and my valve cover leaked out at 108k miles and my oil pan leaked at 130k miles and currently I'm at 140k and so far my oil filter gasket hasn't leaked yet. So these gaskets do last a while in my opinion. Just keep an eye on your motor and you'll be fine
Hey, hope you're having a good day great video btw, I just wanted to ask you what you think of the BMW V12s?
You missed one which is VERY common. The tapping sound from cold start which most owners mistake as normal. Exhaust Camshaft Bearing Alignment.
Just hit 100k 15 M4 6spd valve cover didn’t leak had to replace for PCV failure, I also replaced injectors they all failed, valvetronic sensor failed, still have to do ofhg and oil pan gasket both starting to leak, pulleys squeaking doing them soon w belts, besides that pretty reliable car drive it everyday
I agree they are reliable engines if maintained correctly !
Yeah that crankhub fix aint no joke. I the hunk of metal is like 1k for a quality one and half the shops quote hella install prices, which makes sense since your practically taking a part a large portion of the engine. I've seen pricing from freelancers as low as 2k but pricing as high as 9k from some shops for install/parts. Now with it done though it's nice knowing all I got wrong are those gasket oil leaks lmao
How about the cold engine rattle by incorrectly torqued camshaft bolts causing misalignment and thus what sounds like a hydraulic lifter that's gone weak.
Just hit 100k miles , not issues...100 octane full bolt on tune
Crank hub fix? Which tune? Dct?
what did you do to the crank hub?
How about the aluminum oil drain plug that’s way too easy to strip...
Quick question. I'm in the states, but called the dealership and they didn't have any record of a bulletin or repair notice for the S55 over here. Can you share more details on this?!
Thanks!
Me as well
This is not a recall here in the US because it was a very low failure rate, also it was rectified in 2016 anyway.
Isnt the Crank Hub extra designed to protect the Engine for Overpower? Like the Injektor fails and the Motor gets a real shock...the fixed Crank Hub just would destroy the Block aswell.
Can anyone tell me more about the bulletin number or shed some insight on the S55 Crank Hub recall? I'm in the US and couldn't find anything about a recall on it.
There is no recall for it here in the US as it is a rare fault.
From what i've read, the stock intercooler is INCREDIBLY effective, oftentimes more so than aftermarket units, however, some of the stock ones are known to leak, which is a different (but still valid) concern.
Your goated man I wanted to know more about my engine
Don’t recall bmw recalling the crank bins either…. They have ignored it as very few slip.
BMW has so many problems but people around the world 🌎 still like it and love it !
@BMW Doctor - 6:00 you said the crankhub issue only affects the competition models. Can you confirm that non comp models don't face this issue?
Affects all S55 engines
@@iAintEvenMaddd no this is for 14-16 only. Was resolved in 2017.
better than N55?? (In terms of reliability)
I had my 440i for 4 years now and never had anything leaking. Crank hub for s55s only 2016 before models have issues, the news ones rarely have any crank hub issues, unless super aggressively tuned.
Was this rectified on the lci models by a thicker friction washer between crank hub
As an M4 Owner i can tell you that's not true. Nothing changed mechanically
I got a e87 and the key range is literally 1meter do you think you could help, its had a new key the previous owner said.
That’s not a bad thing ... they clone frequencies now, people are even advised not not to open their car from a distance for safety reasons. I have an e92 and the range is max 3-5 meter
Anyone know what the campaign number is for the crank hub recall? I can't seem to be able to find it anywhere.
There is no recall for the crank hub. The 2017+ MY changed the bedplate for this, having less crank hub issues. The most common occurrences are on the 2015 - 2016 models and even then, it is less than 2%.
I have f82 m4 full bolt on and tune .never had any issue and no oil leak
and what about the crank hub? is it still stock ?
Was never aware there is a recall for the s55s due to the crank hub. Are you based in USA or UK?
He is in uk
@@petercan1020 searched it up on bmw uk recall website and there’s none for s55’s
Hi Dean I’ve got an e46 m3 silver grey manual with sunroof. 61000 miles 2004. What do you think it’s worth? Mint condition
10k
6.5k max
I plan to buy an 2004 325i for 1,300 us dollars, battery and ECU aren't working according to owner. what to look for so if its worth the buying
Music is louder than what's being said.
What are your thoughts on the S58?
It appears like you are trying to ‘do the right thing’ and make a video to assist potential owners in a buying decision. Don’t get me wrong, the sentiment is not lost on me, however, scaremongering helps no one, and it appears like you have completely over exaggerated the crank hub issue (which more or less doesn’t exist on a standard car). To suggest that you should have the rod bearings replaced just because you’re having the sump gasket changed is absurd! I would rather take my chances with the original factory fitted items than that let someone who is potentially under qualified, incompetent or just in a bad mood, mess with some of the most crucial components on any engine. You would be better spending the money changing the oil more frequently, then the rod bearings will likely outlast the car.
Theres no recalls for the S55 in the UK?
Yes there is !
@@BMWDoctor i checked online with my registration and it said there was no recalls? I have a 2015 M3
Then it would of already been done before your ownership. As it was happening most when it was first released some would have got it done some not
So on on a 2020 M2 comp the car probably already has the revised part correct??
@@sonneyanthony6926 yes most of the issues was 2016 and older
Rod bearings replaced? You tripping man. Also, crank hub is so blown out of proportion. Make sure you shift correctly or don't use kick down if you have a dct
I got the crankhub 4 pin upgrade on my f80, still not good to kickdown?
Got slug in my oil cap on my f80 m3 😮
All mechanics think crank hub is a common problem
I have something very important to say: I am big BMW fan, no wonder, right? 😁 And i am also first to comment on this video!✌🏼
Why spend $60k on a car that'll give you oil leaks? I've never owned one, I'm interested and am doing research, but with 3:20 ~ 3:40 that might make me steer away form them. Yeah its "luxury" its NORMAL to have oil leaks, just replace it when it happens. That's some copium if you ask me xD Seems like BMW owners are some serious masochists if that's the case lol I think they're motorcycles are better built than their cars.
Why make such a great engine and make it sound like a weedwacker
Re-manufacture the 80-90s engine.... all these new cars are rubbish.
Theyre too slow mane
those old engine's aren't better perse. the s55 is pretty much bulletproof
Can you be my dad?
