- After removing the engine from the car and disassembling everything, it is time to see what failed inside the engine. We going to check the most common issue with this engines aka the main bearings and the crankshaft. We have found some other issues during the job, like oil nozzle breakage, failed camshafts journals + caps and so on. In this video we going to take a look, what is happening inside the oil pump / vacuum pump.
The car that we are working on:
BMW F10 530xd N57D30

Everyone N57 owner should watch this video
Excellent
Mine failed ages ago and BMW replaced engine for free at 85k. It has since done further 70k and I’m worried it’ll happen again so stumbled on this.
Thanks!
I feel the pressure man :D Try changing the oil pump before that
Again the notorious N57, unfortunately. Thanks for sharing guys. Dutch regards, Nico.
Om de 7~8K olie verversen voorkom je dit wel hoor.
Notorious? It has a bulletproof rep in Australia. The guy has likely not changed the oil, used incorrect oil, or pushed it too hard when cold.
Looks like an oil pump though.
@@davehewisonphoto Yeap, one of those scenarios for sure! bearings will go only when there is no oil between the crankshaft and road bearings, and this will happen when the oil is still not to the working temperature and the engine is being pushed hard. Or oil was just too old with a lot of mileage.
@@35dfred20so true...99% drive them hard...and oil change every 20-25k...thats normal for failure...like u said.. some proper good oil every 10k and engine will last.
I spoke to a bmw warranty man and he said has seen these engines taken apart at 250.000 miles and showed min ware . Oil changes vital
Good luck installing the bulletproof oil pump! Great work as usual!
I think the main problem was a bended crankshaft, I think also this type of "lighter" crank with 4 counterweights was more prone to fail than the old one with 8 counterweights, the crank of the n57d30c m50d should be the best and the price is the same
Ей страшно е ,но поне е в добри ръце колата. Поздрави и успех с ремонта!
The N57 on my X5 had the same issue.
The check valve on the oil nozzle failed alowing the oil pressure to drop on the no. 1&2 rod & main cap
economically not repairable i guess, would be nice to understand the spraying nozzle failure, it's quite concerning, great video as always by the way !
Few colleagues tried to repair the main bearing tunnel, but the engines didn't last really long.
I always check the oil filter, if there are no chips, the bearings is still good .I think so ?
the opening of the frame halls becomes smaller. factory error
I've seen the pressure relief valve in those pumps stick open, venting the majority of the oil into the sump and little to the lubrication system. There's enough pressure normally to cope with that piston spray nozzle being broken I'd say, but the only way to test the pump is by submersing the oil pickup in a container of oil and spinning it anti clockwise with a T45 socket in a battery drill. You should see oil coming from the correct opening on the pump, if it just sprays out the vent hole it's the pressure relief.
Know for sure if I bought a n57 engine, I'd probably fit a new oil pump and do a number of short oil changes to give the engine it's best chance. You can remove the sump on these after removing the gearbox and change the pump wiith the engine in situ, so not the worst job.
You can change the oil pump without removing the gearbox.
@@crank3646 Yeah, really like how easy many things can be done on these cars are even with the N47/N57 engines in situ - think they're great engines, although you do need to change oil more frequently than BMW suggest. Had a couple of these in now with low oil pressure and it was the pump venting, both owners got really, really lucky.
Great content btw, some of the best on CZcams.
@@nemz7505 Thanks nemz! Yes that is why I always suggest changing the oil pump, because of this issue as well
Nice video. I wil try to find the video for the high pressure pump replacement :D
Hiya Crank , lesson for this video Rotating is ok but REVOLUTION would be a better term to describe for the crank spinning, so possibly human error made it fail , bad for the customer but good for you , that's life , expensive lesson for the customer , great video as always thanks for sharing ; )
Thanks Peter! You are right, sounds better. I have already recorded few videos using the rotating term, but in future will try to use your one :)
Is the bosch pump at the end of the video the CR/CP4S1/R40/20-S ? They fail a lot on VAG cars 1.9 / 2.0 TDI engine as well
It is Bosch CP4, the same as on VAG. But there is 10 times easier to do this swap, with CP3 pump than on BMW. At least I haven't seen someone to do it
Thank you for this detailed nice video! Keep it up ! 👍🏼👍🏼👍🏼
Good video. excellent mechanic.
good analysis
Great video. The car is in good hands, I hope that can comfort the owner.
Any b47 motors en the future???
start with measuring crankshaft which is bent as on ALL n57s, its always always that middle one, i have done 5 of them
Is the middle one out of line, not concentrical?
Can the crank be corrected?
@@giselamayer8383 According to a german channel it is almost always at cylinder 3 and 4, from around 160k km typically on heavier vehicles (5er, X5, X6, etc) and not really on 3ers.
@mgoogyi hi, may I ask, I have an 04 E46 330d touring. It was interesting to watch the amount of work that's been possible here just on the driveway with a pair of axle stands. Appreciate the model being worked on here is much newer than mine but from your experience do these crankshaft issues go back to the E46's too? (I note your comment about the 3 series), cheers
Good video👍👍👍
im sure the older high pressure pump doesnt generate enough pressure and that was the reason for the new one
How often should we change this bearings ?
You do a great explanation of every step you take ..
Thank you
At 200k km, after that on every 150k km
it will not help, N57 has issue with crankshaft which bends ,on ALL of N57, its not M57, you must replace crankshaft with bearings
Hi been watching your videos for quite some time now and have to say i am very impressed by your work. I have one question tho. Can the oil pumps on these make noise or are they submerged in oil to the point it is almost imposible? I bought my 330d lci 245hp a month ago, the engine was refurbished by the main dealer 20k km ago (i know what was done since i work as a painter there. I have been noticing a bit of a rattle lately on cold starts. All the chains, sprockets, tensioners and guides are new along with all the crank and main bearings. The oil pump was checked and was fine so they didnt replace it. No oil pressure lights no knocking noises, the vaccum pump also maintains more than -1 bar of vaccum.
Hello! I haven't heard oil pumps to make noises. If they start make any noises believe me, it will end up pretty fast and pretty bad. The pump should always be replaced, because it has an issue with the pressure regulater valve inside.
@@crank3646 thank you for your answer! What are the symptoms of the pressure regulator going bad?
Simple really. We all know after OFHG change that the engine should be primed. I prime even after a filter change. Hand first then starter prime. Should I have to….of course not. But will it help….absolutely
Well done once again, nice engine teardown as always.
How much crankshaft and engine block costs?
Thanks! New ones? I believe it was somewhere around 12-13k Euros
@@crank3646 I had to replace mine, and it was 17k euros
where is your store located at? I am going to buy a BMW I want to make sure it is in good condition
I don't speak english i don't understand all, the failure is from the nozzle break? Low pressure oil for the bearing with nozzle break?
yes, logic is that the hole became bigger thus loosing a lot of oil so pump can not make pressure.
При B57 има ли ги тези проблеми със лагерите и горната верига?
За да си спокоен с този двигател на 200к-240к км смяна верига с основни и биелни лагери + маслена помпа 😉 и да не забравяме по честа смяна на маслото а не както казват от бмв на 30к км 😀
Oil change every 5 to 10k max and you should be good with this engine, do dpf and egr off it is better for the engine
You can look for all the excuses you want. The fundamental problem is that these engines are poorly designed and built. The only answer is to stop buying them.
truth
Well done SHITTY BMW
Is n55 beter choice?
Not treu mine works fine after 212000k
so detailed, except no details of engine mileage?
How many miles was on this engine?
Страхотно видео. Каква е причната довела до тази повреда ?
Unregular oil changes, people do oil changes every 15-20.000+kms which is too much for these engines, do it every 5-8000 should be no problem (i know its expensive)
@@zlatkokrumpirko4287true, i change oil every 10k km..with oil filter.. and with good oil and engine would last
I wanted to replace my A7 with a bmw 640d but now i will think twice about it 😥😥
Buy the 640i instead. 3.0 petrol turbo engine found in m135i's etc, tune see's them at 380bhp easy, great sound, and great engine!
How do I prevent this happening? Any modifications available
Depending on how you drive, change oil every 10k km or less and use high quality engine oil.
Don't drive hard when the oil is cold.
@@agen1man true
@@davehewisonphotovery important. And engine warm up so quickly... but 99% ppl don't give a fuck..and with cold engine 50% pedal gas...torque is already 3/4...+ 20k oil change and engine is done at 200k.
Oil change every 10k with quality one.
Warm it up. And N57 would last.
Здравей.Къде се намира сервиза ти в Бургас ?
Здравейте! Има координати за връзка в описанието на видеото
Май са прекалено пренатегнати лагерите и за това е започнало това страшно износване, въпреки че са сменени ?
Автора каза, че според него като се е отчупила пръскалата на 2ри цилиндър е паднало налягането поради разликата в диаметъра. От там е задрал основния лагер.
Just happened to my buddy yesterday. We did major service - intake blast cleaning, Top timing chain with tensioner, valve cover gasket, fresh oil, 800km later it spun a bearing. There were like 3-4 weird flakes inside the old oil filter so nothing really worrying…
Hi,
I just did my oilchange an also had 3-4 very little aluminum chips. Very little. Iam about to open my engine. Not willing to drive it any more. What size did they have? Mine were about 0,5mm x 0,5mm
@@giselamayer8383 im sorry to say they were the same size. Turns out these engines fail because crankshafts bend and crack over time.
Hi, did you maybe know the mileage when that bearing spun?
@@marinpralija2047 ~240k kms
it was the 303hp version, e70 40d

Здравей! Какво би препоръчал на всеки, който иска да си купи кола с такъв мотор ?
Да си приготви 8-9к за първоначално обслужване :D
@@crank3646 Благодаря, за отговора. Очаквах сумата да е 5 :) Това, което наистина ме притеснява е да не си купя кола и после да се наложи да и търся мотор.
@@georgievvladimir За съжаление доста чест сценарий. Ако се използват афтърмаркет части, може и такава да е сумата, но ако се ползват оригинални части няма как да е по-малко
@@crank3646 8-9к??! Глупости!!! Refurbished engine струва 2300 паунда с 2 години гаранция :)
@@petkotodorov2655 Аз против нямам, взимайте и дерзайте. Аз моя опит няма да го споделям, че ще кажете че си ги насосвам. Само ще кажа, успех с гаранцията като стане нещо. Доскоро един продаваше двигатели с 200к км гаранция или 5 години експлоатация ама като почнаха да сгъват нещо смени телефония номер.
