You have discovered why some BMW's are for sale or are traded in.Service advisor at BMW said the timing chain needs to be replaced. He is very vague and I can't get much information out of him. It is so frustrating. So the timing chain and rail guides are replaced. How reliable will that engine be after timing chain and guide rail pieces were found in the oil?
The cars have a reputation for failure starting @ 60k miles, and that is well deserved. But this is ridiculous....
