ЦЕПЬ БЫЛА ИДЕАЛЬНОЙ... Но мотор всё равно погиб! BMW M57 635d E64

HELLCAR Workshop — Estonia I'm on Instagram: (  / pavel_dovzenko  ) For inquiries: [email protected] A BMW 635d arrived to us for repairs directly on a car transporter after the timing chain broke. It seemed like a common occurrence... but after disassembling the engine, something unexpected was discovered. Overall chain wear was minimal, but several links had become critically worn, which led to the chain breaking. In this video: ✔ Unloading a car from a truck. ✔ Complete disassembly of an M57 engine. ✔ What caused the chain to break? ✔ Could it have been prevented? ✔ At what mileage is it really necessary to change the chain on a BMW M57?
