Car has been running great with no indication of a motor problem. Imagine my shock when I pulled the drain plug on my FE and see half of a circlip. Don’t know where it came from but my first thought is a piston wrist pin. Any other ideas such as something out of rock arm assemblies would be appreciated. I’m running stock Ford adjustable rocker assemblies with aftermarket end supports. I’m pulling the valve covers and will scope the pan and cylinders. Any ideas will be greatly appreciated.
