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!

    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.

    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

    I think you have too many decimal places in your runout specification. Actually, .006mm is well within the manufacturer allowed tolerance.
