Metal flakes in oil. Horrible or not so bad?
My 2006 m5 e60 with 70k miles started making a knocking noise from passenger side lifter closest to windshield. Reduced power. Garaged and shut down. Independent Bmw mechanic gave a quick look. Suggested engine replacement, but did not pull anything open. Metal flakes of copper/brass color in oil. Options seem like crankshaft wore out,or rod bearings. I am having the oil pan pulled to inspect further. It seems that I mostly read to just replace the engine. I'm hoping someone hear might give their experience that it is not complete engine failure (potentially) if the crankshaft, rod bearings, etc can be replaced and the system flushed. I understand that these are general problems and no specific answers are rock solid without more info, but I'm looking for a ray of hope here. I have ordered a test kit from blackstone also
