Hey all, I have a 2011 BMW 335is and I inspected my filter at my last oil change and it looks like this opened up. Is this alarming or is a certain amount ok? The oil looked pretty clean. The car did have some engine work, the intake camshaft bearing ledge was replaced and it seems to be aluminum like it. Although that was in April, can it still be remenants of that breaking in? The yellow stuff seems to be filter material rather than copper. This is also just 3000KM interval, I had another oil change in August.
