is that the lighting or do I see copper on the bearing?
It's worn through the coating. There's a little divot by the oil hole also. This is the worst one. I'm going to change them out.is that the lighting or do I see copper on the bearing?
My knock happened suddenly, you would think the culprit would be obvious like yours.
Sometimes when an engine sits for a while (a month or so) a piece of carbon comes loose from the combustion chamber near the valves and sticks to the top of the piston and contacts the head,which can sound like lower end noise since it forces the rod against the crank momentarily. Any chance that could be the issue?
