Copper flakes in oil pan
Help, my engine produces "gold flakes"!
Removed today oil pan from my Gen4 engine just to check if all looks good from the botton and saw quite many copper flakes in oil pan!?
Made a photo of it. Has anyone had similar issue?
There are no larger pieces, only flat flakes (0.5 to 1.5mm) you see on picture.
Did cut open the oil filter and found copper dust there too.
Upwards from oil pan everything is very clean and cannot see any debries there.
Where can it come from?
I can exclude clutch and cylinder head, it is off and valve clearances were good.
