A tiny fleck of copper from the funnel you used to fill? Copper anti-seize? Meh... |
I’ve had multiple low pressure incidents and none of them showed up on my UOA report.
Been scratching my brain trying to think of what else would show up as copper besides a rod or main and not having any luck. I believe the copper layer is a bit deep in the bearing, I could probably pull one to check later this weekend. Maybe some crank thrust took the edge off a bearing but I don’t see that as much better of a problem.
