Well, this hurts to write, I've just done an oil change on my R and found some metal fragments in the oil, they were very small and seemed like potentially brass or copper (judging by colour)
Is there a known likely cause of this? Or am I due for a full rebuild.
The car runs and drives well, makes full boost and vacuum, with no knock, a slight sound through the low 2000rpm's which sounds like a vibration more than any kind of knocking or engine sounds. Minor oil leak which I'm 90% sure is the turbo drain hardline, but won't be able to confirm until the weekend.
Any advice on how to tackle this would be appreciated.
