Rebuilding my 640D N57 engine bottom end
Автокөліктер мен көлік құралдары
After finding metal shavings in the oil filter i decided to take engine out and replace the most likely cause which are the main bearings. In the end it turned out i needed a new crankshaft as the original had runout of 0.006mm.
Engine was reasembled with new headgasket, Main bearings, conrod bearing, crankshaft, oil pump, chains and tensioners, oil cooler seals, main seals, waterpump, thermostat and rocker cover gasket.

Hows it holding up? Hope it lasts 100k for you! I'm tempted to get a spare engine just because i dont trust the n57 bottom ends!
That's one hell of a job, well done! 👌 And that in-line 6 sound... man there's nothing better! 💪
Not that long ago, BMW 3.0 diesel engines were known for reliability. Now it seems that 2.0 diesels are more reliable than 3.0.
Amazing work, congratulations
Bravo! 👍👍👍
Awesome! Well done!
Respect,Nice work
Great work
Great work. The chain guides were upadated , the ones you have on go brittle and break
dobra robota !
Sehr gute Arbeit😎👍
Good job
nice one boy!
Hi Maciej, Admirable work. My Irish reg’d F06 has 143,000km. I will need to change the timing chains etc sometime. Do you work on other people’s cars?
Did you even check cylinder wear before honing them?
What was the issue for it to be rebuilt? my 640d will need the same rebuild, but i dont know how bad t is inside the block as been knocking sounds are loud
Did you have to resurface the head or the block for this repair?
Those jacks looks a bit unsafe to be working underneath 😊
Witam. Co to za preparat, którym spryskujesz cylindry podczas honowania? Dzięki z góry za odpowiedź .pozdrawiam. dobra robota.
What was the total parts wise?
What's the cost of parts nd labour
Have you checked the geometry of the cylinder block? It is believed that the cylinder block also deforms under load. What was the mileage on your car before the repair? Thanks..

I have checked the block, i did not spin a bearing, just found metal shavings and did this preventetively. Car was at 260k kms, done 13k since so far so good
Nice job, but - I think You should also replace the oil cooler - some of this meal shavings can stay at this place. Also are You sure is your block is straight and all bearings are concentric? I hope yours engine works well, regards.

Every crank journal has its own tolerance lasered on the block. There are bearing sets with all the same dimensions, but as much as I know you need to lookup the numbers on the block to determine which actual bearing size you need.. i hope your engine will last forever, it was a lot of work! edit: this is what i mean, here it is all bearing size 2: kzread.info/dash/bejne/lplht8athrW1l6w.html

Yes block and crankshaft both have their own numbers to tell which bearing size you need. Bearing sets are for conrod bearing i dont believe there are sets for main bearings as theyre all sold individually. All was done according to ASO instructions either way same as in the link you posted

Btw Im pretty sure anyone who had to do bearings on this engine has seen this video
I think you have too many decimal places in your runout specification. Actually, .006mm is well within the manufacturer allowed tolerance.
@maciejcymerys191

Yes i ment 0.06mm, max acceptable runout is 0.02mm, ive mixed mm with inch decimals
