BMW 3.0L Diesel B57 Engine Review | B57 Weak Points and Comparison with Other Engines

[@IT_Scientist]

Nope. Basicaly they finally debuged their 6cyl diesel to perfection! This time they made it perfect. So much service we had so far with cars with B57 nothing and I mean NOTHING needed to be chainged yet! Once client insisted to change the chains on 300k km mileage, but we did it just because he asked, and the chain was pefectly okay. Bottom problems also fixed, bearings good, pump is good, shaft is great, fuel system perfect, now even single turbo variants all uses piezo injectors.. So only thing you have to do is to get a car with as low mileage as possible and save it from that 30k km oil change period nonsense from BMW, and treat it every 9k with quality oil, and it will serve you forever! But if you got one with mountains of oil mud inside noone will help you... So I am so glad they finally made this exelent engine lineup! Both B58 and B57 simply requeres NO ADDITIONAL attention at all, just regular maitanance, if you happen to have B serries IC engine, you are lucky, just delete that BMW oil change periods 25-30k from your head, do it every 10k and you good to go! There is nothing to even compare here with N57s, totaly differend engine, this video is a bit missleading... You can even leave all eco shit on it, EGR, AdBlue etc.. all systems works now perfectly ideal now! Maintain and just Enjoy your B series!

I've already seen two b57 engines with broken timing chains both around 350k km

@@MrTurboDimaid say as just general rule of thumb for any N/B series bmw engine , inspect chains at 75,000 miles and change chains every 100,000 regardless.

M57 was pretty damn close to perfection

Please do a video for b57 vs n57. Love from India

I really want to know did BMW change the design of the crankshaft bearings on the B57?Are they any better than the N57 one's?I think it's disgraceful for such a great brand like BMW and a brand renowned for making the best driving cars,to have such factory made flaws like faulty crankshaft bearings.

[@chippyjohn1]

Exactly the same as N57. Difference is main bearings went to 55mm in N57 from 60mm in M57. B57 creates more torque and earlier than N57, so more stress on bearings at low rpm.

[@IT_Scientist]

@@onlyhuman7420 yes the whole bottom end engines problems are solved now, bearings will not degrade of you simply do oil change every 10k.km. They revised cylinders, pistons, injection systems as well and on the good side. As I said we teared appart B57 on 300k km mileage for a chain job, and there was nothing to be done, the chain was still in its normal operating range. Ofc.the inside of it was nice and clean which just confirms that only thing you need to care about now is an regular good quality oil change, like Xados for example. It will give it some extra coating for the parts. I also always use at least once one expensive bottle of metal treatment solution from Xados it's called like Stage1 revitalant costs arround 100€ it's a great additive to fresh oil that you can do every 100k km, it will polish and smooth out the most scrached parts, and works most on places where the load is biggest like on bearings, creates extra ceramic layer for your even more peace of mind on top of already very well done and redesigned engine after all lessons learned from past N series ones. Although I got to say with same treatment I was able to do 330000km on my N57D30A Stage2, was working like a clock before I sold it to my buddy who drives it further happy till this day! Remember: forget 20-30k oil periods, do it every 9-10k with Xado oil and use at least once Stage1 additive from them invest extra 100€. And enjoy that smoothness, power, torque and realibility on both N and now even more forgiving B series. And stop reading kids comments whos knowlage is from a guy who said a guy...etc. Listen people who actually works on them. My N57D30A original oil pump on 330000km was giving strong 1.1bar of oil pressure while its warm and perfectly working limiter at 4.5bars while its cold! Just show em some love and those diesels will get you arround the world!

M57n e61 here 330k driven hard daily ...and no chain stretch. Such a pity reliability went down from here. Think ill buy an n57 35d anyway. I had an e60 n47 see over 200k miles and had chain inspected before i sold and was alll good. I find bmw quite reliable in general. IBS system has been a nuisance on a few cars though.

[@shadowchrome_]

do not get N57 35d engine they have issues with bottom end bearings and in some cases even knock cranks out, very common to see with engine failures. even 30d model is far less likely but still susceptible to those issues too. keep ur m57 and save up money and get B57 if you really want to change

[@kol8fire]

​@shadowchrome_ ya ive since changed my mind, ive gotten somewhat handy at working on cars and do all my own maintenance and mods currently but replacing bearings seems like a lot of effort and would be paranoid i did someting incorrectly as it would be my first time doing it...and the cost of of paying to get it done here in Australia would be astronomical😮. Its just a shame as i do like the aesthetic of f10 and 640d even better, many going pretty cheap here, i didnt like their handling compared to e60 though. I think an m57 conversion into a patrol or old pajero will keep me busy and happy for now

[@shadowchrome_]

@ yeah it really is a shame about them as i agree, the F10 5 series and the 6 series gc are gorgeous cars and bloody quick and great on fuel but its not worth the hassle and paranoia of it randomly going kaboom. but yeah honestly M57 in a pajero swb would be wayyy more fun and reliable😭

Need help. 530xd 20k km 2022 lci. Motor feels and sound great, vibration of motor is normal, hood also feels nearly no vibration. However inside you feel vibration a lot (as if it resonates, seat and steering vibrations are felt, nearly to massage level) - same in all gears, N, D, R, P… all same - it is excessive only at idle…. As soon as you get to 900-1000rpm it is quite and smooth - hot or cold start also makes no difference. - oil is fresh (every 10k km I change) Motor was dropped down and installed back because car needed left front part changed due to accident. What can cause such vibration ?

[@willlong4258]

You need engine mounts
